In situ atomic force microscopy study of Alzheimer's beta-amyloid peptide on different substrates: new insights into mechanism of beta-sheet formation. (1/503)

We have applied in situ atomic force microscopy to directly observe the aggregation of Alzheimer's beta-amyloid peptide (Abeta) in contact with two model solid surfaces: hydrophilic mica and hydrophobic graphite. The time course of aggregation was followed by continuous imaging of surfaces remaining in contact with 10-500 microM solutions of Abeta in PBS (pH 7.4). Visualization of fragile nanoscale aggregates of Abeta was made possible by the application of a tapping mode of imaging, which minimizes the lateral forces between the probe tip and the sample. The size and the shape of Abeta aggregates, as well as the kinetics of their formation, exhibited pronounced dependence on the physicochemical nature of the surface. On hydrophilic mica, Abeta formed particulate, pseudomicellar aggregates, which at higher Abeta concentration had the tendency to form linear assemblies, reminiscent of protofibrillar species described recently in the literature. In contrast, on hydrophobic graphite Abeta formed uniform, elongated sheets. The dimensions of those sheets were consistent with the dimensions of beta-sheets with extended peptide chains perpendicular to the long axis of the aggregate. The sheets of Abeta were oriented along three directions at 120 degrees to each other, resembling the crystallographic symmetry of a graphite surface. Such substrate-templated self-assembly may be the distinguishing feature of beta-sheets in comparison with alpha-helices. These studies show that in situ atomic force microscopy enables direct assessment of amyloid aggregation in physiological fluids and suggest that Abeta fibril formation may be driven by interactions at the interface of aqueous solutions and hydrophobic substrates, as occurs in membranes and lipoprotein particles in vivo.  (+info)

Ethanol-induced structural transitions of DNA on mica. (2/503)

The effect of ethanol on the structure of DNA confined to mica in the presence of Mg2+was examined by varying the ethanol concentration and imaging the DNA by atomic force microscopy. Contour length measurements of the DNA show a transition from all-B-form at 0% ethanol to all-A-form at >25% ethanol. At intermediate ethanol concentrations, contour lengths suggest that individual molecules of air-dried DNA are trapped with mixed compositions of A-form and B-form. The relative composition depends on the ethanol concentration. Fitting the length distributions at intermediate ethanol concentrations to a simple binomial model results in an upper bound estimate for the A-form and B-form domains of approximately 54 bp in the individual molecules. In addition to length changes, the apparent persistence length of DNA decreases with increasing ethanol concentration. At high concentrations of ethanol (>20%), DNA formed several higher order structures, including flower shaped condensates and toroids.  (+info)

Microstructure and homogeneity of dental porcelain frits. (3/503)

The microstructure and homogeneity of three commercial dentin and incisal unfired porcelain frits (one conventional and two ultra-low fusing types, fused-to metal were analyzed by X-ray diffractometry, scanning electron microspectroscopy, and wavelength- and energy dispersive X-ray microspectroscopy. The average contents of tetragonal and cubic leucite for the conventional and one of the ultra-low fusing type frits were 20.1-22.6 wt% and 0-2.6 wt%, respectively, whereas those of another of the ultra-low fusing type frits were about 11.5-11.6 wt% and 2.9-4.6 wt%, respectively. The conventional type frits seemed to be admixtures of three kinds of glass frits. One of the ultra-low fusing type frits seemed to be an admixture of four kinds of glass frits. Another ultra-low fusing frits seemed to be only one kind of glass frit dispersed with small size, less than 1 micron, leucite crystals. There were no remarkable differences in microstructure and homogeneity between dentin and incisal porcelain frits in each brand.  (+info)

Phase imaging by atomic force microscopy: analysis of living homoiothermic vertebrate cells. (4/503)

Atomic force microscope-based phase imaging in air is capable of elucidating variations in material properties such as adhesion, friction, and viscoelasticity. However, the interpretation of phase images of specimens in a fluid environment requires clarification. In this report, we systematically analyzed atomic force microscope-derived phase images of mica, glass, and collagen under the same conditions as used for living cells at various tapping forces; the resulting data provide critical information for the interpretation of phase images of living cells. The peripheral regions of COS-1 cells consistently show a more negative phase shift than the glass substrate in phase images at set-point amplitude: free amplitude (Asp/A0) = 0.6-0.8. In addition, at all Asp/A0 values suitable for phase imaging, tapping frequency appears to be high enough to ensure that phase shifts are governed primarily by stiffness. Consequently, phase imaging is capable of high resolution studies of the cellular surface by detecting localized variations in stiffness. We demonstrate that phase imaging of a bifurcating fiber in COS-1 cell cytoplasm is readily capable of a lateral resolution of approximately 30 nm.  (+info)

Atomic force microscopy imaging of DNA covalently immobilized on a functionalized mica substrate. (5/503)

A procedure for covalent binding of DNA to a functionalized mica substrate is described. The approach is based on photochemical cross-linking of DNA to immobilized psoralen derivatives. A tetrafluorphenyl (TFP) ester of trimethyl psoralen (trioxalen) was synthesized, and the procedure to immobilize it onto a functionalized aminopropyl mica surface (AP-mica) was developed. DNA molecules were cross-linked to trioxalen moieties by UV irradiation of complexes. The steps of the sample preparation procedure were analyzed with x-ray photoelectron spectroscopy (XPS). Results from XPS show that an AP-mica surface can be formed by vapor phase deposition of silane and that this surface can be derivatized with trioxalen. The derivatized surface is capable of binding of DNA molecules such that, after UV cross-linking, they withstand a thorough rinsing with SDS. Observations with atomic force microscopy showed that derivatized surfaces remain smooth, so DNA molecules are easily visualized. Linear and circular DNA molecules were photochemically immobilized on the surface. The molecules are distributed over the surface uniformly, indicating rather even modification of AP-mica with trioxalen. Generally, the shapes of supercoiled molecules electrostatically immobilized on AP-mica and those photocross-linked on trioxalen-functionalized surfaces remain quite similar. This suggests that UV cross-linking does not induce formation of a noticeable number of single-stranded breaks in DNA molecules.  (+info)

Computer-assisted morphometry of cell-substratum contacts. (6/503)

AIM: Quantitative analysis of size and shape of the cell-substratum contacts in Dictyostelium and comparison of these parameters between wild-type cells and the cells bearing cytoskeletal protein mutations. METHODS: Reflection interference contrast microscopy (RICM) was used to image the areas of contact between aggregation-competent Dictyostelium cells and weakly adhesive mica surfaces. The cell-substratum contact areas were automatically identified in RICM micrographs by digital image processing. Information about the size and shape of the contact areas was obtained by using the shape descriptors based on two-dimensional geometrical moment invariants. RESULTS: Lack of either of the two actin-crosslinking proteins, a-actinin and 120 kDa gelation factor, similarly affects the cell-substratum interactions of Dictyostelium cells. The shape descriptors, elongation and dispersion, of the contact areas were reduced by 10% to 30% in mutant cells when compared to the wild type, but the size of the contacts was not affected. CONCLUSION: Video microscopy combined with digital image processing and quantitative image analysis is capable of revealing small phenotypic effects of cytoskeletal protein mutations on the level of single cells. Such automated microscopic methods are expected to gain importance and find a widespread use in biomedicine.  (+info)

Risks of respiratory disease in the heavy clay industry. (7/503)

OBJECTIVES: Little information is available on the quantitative risks of respiratory disease from quartz in airborne dust in the heavy clay industry. Available evidence suggested that these risks might be low, possibly because of the presence in the dust of other minerals, such as illite and kaolinite, which may reduce the harmful effects of quartz. The aims of the present cross sectional study were to determine among workers in the industry (a) their current and cumulative exposures to respirable mixed dust and quartz; (b) the frequencies of chest radiographic abnormalities and respiratory symptoms; (c) the relations between cumulative exposure to respirable dust and quartz, and risks of radiographic abnormality and respiratory symptoms. METHODS: Factories were chosen where the type of process had changed as little as possible during recent decades. 18 were selected in England and Scotland, ranging in size from 35 to 582 employees, representing all the main types of raw material, end product, kilns, and processes in the manufacture of bricks, pipes, and tiles but excluding refractory products. Weights of respirable dust and quartz in more than 1400 personal dust samples, and site histories, were used to derive occupational groups characterised by their levels of exposure to dust and quartz. Full size chest radiographs, respiratory symptoms, smoking, and occupational history questionnaires were administered to current workers at each factory. Exposure-response relations were examined for radiographic abnormalities (dust and quartz) and respiratory symptoms (dust only). RESULTS: Respirable dust and quartz concentrations ranged from means of 0.4 and 0.04 mg.m-3 for non-process workers to 10.0 and 0.62 mg.m-3 for kiln demolition workers respectively. Although 97% of all quartz concentrations were below the maximum exposure limit of 0.4 mg.m-3, 10% were greater than this among the groups of workers exposed to most dust. Cumulative exposure calculations for dust and quartz took account of changes of occupational group, factory, and kiln type at study and non-study sites. Because of the importance of changes of kiln type additional weighting factors were applied to concentrations of dust and quartz during previous employment at factories that used certain types of kiln. 85% (1934 employees) of the identified workforce attended the medical surveys. The frequency of small opacities in the chest radiograph, category > or = 1/0, was 1.4% (median reading) and seven of these 25 men had category > or = 2/1. Chronic bronchitis was reported by 14.2% of the workforce and breathlessness, when walking with someone of their own age, by 4.4%. Risks of having category > or = 0/1 small opacities differed by site and were also influenced by age, smoking, and lifetime cumulative exposure to respirable dust and quartz. Although exposures to dust and to quartz were highly correlated, the evidence suggested that radiological abnormality was associated with quartz rather than dust. A doubling of cumulative quartz exposure increased the risk of having category > or = 0/1 by a factor of 1.33. Both chronic bronchitis and breathlessness were significantly related to dust exposure. CONCLUSIONS: Although most quartz concentrations at the time of this study were currently below regulatory limits in the heavy clay industry, high exposures regularly occurred in specific processes and occasionally among most occupational groups. However, there are small risks of pneumoconiosis and respiratory symptoms in the industry, although frequency of pneumoconiosis is low in comparison to other quartz exposed workers.  (+info)

Polymer-cushioned bilayers. II. An investigation of interaction forces and fusion using the surface forces apparatus. (8/503)

We have created phospholipid bilayers supported on soft polymer "cushions" which act as deformable substrates (see accompanying paper, Wong, J. Y., J. Majewski, M. Seitz, C. K. Park, J. N. Israelachvili, and G. S. Smith. 1999. Biophys. J. 77:1445-1457). In contrast to "solid-supported" membranes, such "soft-supported" membranes can exhibit more natural (higher) fluidity. Our bilayer system was constructed by adsorption of small unilamellar dimyristoylphosphatidylcholine (DMPC) vesicles onto polyethylenimine (PEI)-supported Langmuir-Blodgett lipid monolayers on mica. We used the surface forces apparatus (SFA) to investigate the long-range forces, adhesion, and fusion of two DMPC bilayers both above and below their main transition temperature (T(m) approximately 24 degrees C). Above T(m), hemi-fusion activation pressures of apposing bilayers were considerably smaller than for solid-supported bilayers, e.g., directly supported on mica. After separation, the bilayers naturally re-formed after short healing times. Also, for the first time, complete fusion of two fluid (liquid crystalline) phospholipid bilayers was observed in the SFA. Below T(m) (gel state), very high pressures were needed for hemi-fusion and the healing process became very slow. The presence of the polymer cushion significantly alters the interaction potential, e.g., long-range forces as well as fusion pressures, when compared to solid-supported systems. These fluid model membranes should allow the future study of integral membrane proteins under more physiological conditions.  (+info)

Results obtained by direct measurements of the forces acting between polar mica surfaces interacting across solutions of triolein containing phosphatidylethanolamine (PE), polyglycerol polyricinoleate (PGPR), and a PE/PGPR mixture are presented. It was shown that PE adsorbed on mica from anhydrous triolein and thus rendered the surface nonpolar. The change in ordering of the liquid triolein molecules induced by bringing two such surfaces together gives rise to a structural force with two force barriers. In contrast, the adsorption of PGPR from anhydrous triolein resulted in a steric force barrier with a range of 120 Angstrom. It was also found that from the mixture of PE and PGPR in triolein both additives adsorbed as a complex on mica surfaces. The presence of these aggregates on the surfaces gave rise to a very long-range strong repulsive force. We discuss the implication of the measured forces to colloidal stability of particle dispersion in nonpolar media and compare the efficiency of ...

Normal and friction forces were measured between physically adsorbed and chemically grafted layers of hyaluronic acid (HA), an anionic polyelectrolyte in presence the of lubricin (Lub), a mucinous glycoprotein on mica surface using a Surface Forces Apparatus (SFA) with a surface radius R~2cm. This work demonstrates that high friction coefficients does not necessarily correlate to surface damage and that chemically grafted HA acts synergistically with Lub to provide enhanced wear protection to the surface. Increasing the concentration of Lub enhances the threshold load that a chemically grafted HA surface can be subjected to before the onset of wear. However, Lub fails to provide wear protection if HA is physically bound (not chemically grafted) to the mica surface and damage occurs at loads less than 1 mN (Pressure, P, 10atm) regardless of the amount of Lub, indicating that the molecules in the bulk play little or no role in camouflaging the surface from damage. Lub penetrates into the ...
The main result of our simulation is that the restructuring of a monolayer consisting of C18 surfactant molecules was observed, but any restructuring of a monolayer consisting of C24 surfactants never underwent such a restructuring. The C24 surfactants maintained the monolayer structure in both P1 and P2 simulations, as depicted in Fig. 2. By contrast, cylindrical micelles formed during the P1 simulation for C18 molecules, and in the meantime water molecules from the top of the monolayer proceeded toward the mica surface and replaced the surfactants. During the P2 simulation, these cylindrical micelles were further transformed into spherical ones. The processes for C18 surfactants are illustrated in Fig. 3. For a better understanding of the dynamics of the spatial rearrangement of the systems, the number densities of certain components were calculated as a function of the position along the normal axis with respect to mica sheets at different moments in time. The five components that were ...
Study of the transformation of smectite to illite, chlorite or vermiculite via interstratified clay minerals needs precise qualitative and quantitative determinations of the different layers in the mixed-layer clays and is generally based on X-ray diffraction (XRD) patterns after specific treatments of the clay samples. Saturation with K or Mg followed by ethylene glycol (EG) solvation are classical methods used to identify high-charge smectite and vermiculite. These procedures have been applied to two experimental clays, one composed of smectite layers and the second, a mixture of vermiculite and smectite layers. Different methods of glycolation (EG vapor or liquid EG) produce significant differences in the XRD patterns. Comparison with literature data indicates that K-saturated, high-charge smectite (~0.8 , total charge ,1/unit-cell) and Mg-vermiculite (whatever its charge) do not expand in ethylene glycol vapor (d values ~14-15 Å). Expansion to 17 Å in liquid ethylene glycol occurs for ...
The clay minerals have iron associated with them in several ways: 1. (1) as an essential constituent 2. (2) as a minor constituent within the crystal lattice where it is in isomorphous substitution and 3. (3) as iron oxide on the surface of the mineral platelets. Nontronite, hydromica, some chlorites, vermiculite, glauconite and chamosite contain iron as an essential constituent. Kaolinite and halloysite have no site within the lattice for iron, but in certain environments iron oxide (goethite or hematite) is intimately associated as a coating on the micelles. Analyses of clay minerals show that the content of Fe2O3 varies: 29 per cent (nontronite), 7??3 per cent (griffithite), 4.5 per cent (hydromica), 5.5 per cent (chlorite), 4 per cent (vermiculite) and 18 per cent (glauconite). The FeO content is: 40 per cent (chamosite), 7.8 per cent (griffithite), 1-2 per cent (hydromica), 3 per cent (glauconite) and 2 per cent (chlorite)....
Abstract: In a natural clay, the occurrence of a high sensitivity, i.e. a high quotient between the shear strength of the undisturbed and remolded softs respectively, under undrained conditions, is connected to thixotropic effects and to quickness.. The general composition of the soils in which quick clay occurs is described, and mention is made of the occurrence of non-argillaceous rock fragments in a matrix of clay particles. Illite is the main clay mineral. Quickness occurs both in salt-leached, marine deposited clays and in clays deposited in fresh water. The pore water of these clays is low in electrolytes and undecomposed organic material. It is found that quick clays often occur near peat and similar humic deposits. Also briefly discussed is the internal stress distribution in natural clays under various consolidation conditions, the structure of quick clays and their conditions of formation. The consistency of clays is considered, as is the stability and coagulation conditions of ...

It has been shown that expression of ligands for NKG2D is associated with malignant transformation (15), and MICA expression was described for many epithelial tumors. This has led to the implication that the NKG2D/NKG2DL system may play an important role in immune surveillance of tumors (17). In fact, two recent reports described that tumor cells highly expressing NKG2DL were rejected by NK cells and CD8 αβ T cells and stimulated tumor immunity against the parental cell lines in a mouse model (16, 22). It was shown that the immune response observed in these studies was critically dependent on the expression levels of NKG2DL on the tumor cells. Therefore, reduction of MICA expression by release from the cell surface would potentially reduce immunogenicity of tumor cells. To investigate whether the effect of sheddases on MICA surface expression mirrored the changes in the levels of sMICA in the culture supernatants, C1R-MICA*04 cells, HCT116 cells, and HeLa cells were cultured in fresh culture ...
The interaction between lipid bilayers in water has been intensively studied over the last decades. Osmotic stress was applied to evaluate the forces between two approaching lipid bilayers in aqueous solution. The force-distance relation between lipid mono- or bilayers deposited on mica sheets using a surface force apparatus (SFA) was also measured. Lipid stabilised foam films offer another possibility to study the interactions between lipid monolayers. These films can be prepared comparatively easy with very good reproducibility. Foam films consist usually of two adsorbed surfactant monolayers separated by a layer of the aqueous solution from which the film is created. Their thickness can be conveniently measured using microinterferometric techniques. Studies with foam films deliver valuable information on the interactions between lipid membranes and especially their stability and permeability.

A molecular level understanding of interaction forces and dynamics between asymmetricapposing surfaces (including end-functionalized polymers) in water plays a key role in the utilization of molecular structures for smart and functional surfaces in biological, medical, and materials applications. To quantify interaction forces and binding dynamics between asymmetric apposing surfaces in terms of their chemical structure and molecular design we developed a novel surface forces apparatus experiment, using self-assembled monolayers (SAMs) on atomically smooth gold substrates. Varying the SAM head group functionality allowed us to quantitatively identify, rationalize, and therefore control which interaction forces dominated between the SAM surfaces and a surface coated with short-chain, amine end-functionalized polyethylene glycol (PEG) polymers extending from a lipid bilayer. Three different SAM-terminations were chosen for this study: (a) carboxylic acid, (b) alcohol, and (c) methyl head group ...
One-pulse magic angle spinning (MAS) 29Si and 1H-29Si cross-polarization (CP) MAS nuclear magnetic resonance (NMR) spectroscopy was performed on minerals with OH groups and on hydrous aluminosilicate glass samples. The silanol-group samples used were krauskopfite, rosenhahnite, thaumasite, ussingite, and KHSi2O5 with known Si to H distances and ellenbergerite, the proton positions of which are not as well defined. The Si-H distances from the minerals can be compared with the cross-polarization time constants (τSiH) and the proton spin-relaxation times in the rotating frame [τ1ρ(H)], and a rough correspondence exists between a minerals shortest Si-H distance and its τSiH value. Also, fast [τ1ρ(H)] values correspond to large bulk H densities. The CP spectra of the hydrous aluminosilicate glass samples were fitted with two peaks, representing two different Si environments within the glass structure. The contact-time curves of the higher frequency peak imply τSiH similar to the mineral ...
Descrição: We establish and quantify correlations among the molecular structures, interaction forces, and physical processes associated with light-responsive self-assembled surfactant monolayers or bilayers at interfaces. Using the surface forces apparatus (SFA), the interaction forces between adsorbed monolayers and bilayers of an azobenzene-functionalized surfactant can be drastically and controllably altered by light-induced conversion of trans and cis molecular conformations. These reversible conformation changes affect significantly the shape of the molecules, especially in the hydrophobic region, which induces dramatic transformations of molecular packing in self-assembled structures, causing corresponding modulation of electrostatic double layer, steric hydration, and hydrophobic interactions. For bilayers, the isomerization from trans to cis exposes more hydrophobic groups, making the cis bilayers more hydrophobic, which lowers the activation energy barrier for (hemi)fusion. A ...

To date, the fundamental details of the molecular structural changes and associated mechanisms, which take place during the formation of aluminosilicate geopolymer gels, have remained largely elusive. Here, density functional theory-based coarse-grained Monte Carlo modeling, a multiscale simulation technique, is used to simulate the geopolymerization reaction and to determine the molecular mechanisms controlling this process. Silica supplied by the alkaline solution plays a significant role in enhancing the dissolution of the solid aluminosilicate precursor (metakaolin, in this case) and the polymerization of the gel. In the reaction between NaOH and metakaolin, in the absence of initially dissolved silica, the solid precursor completely dissolves and the aluminosilicate gel forms via the percolation of small aluminosilicate clusters. On the other hand, in the presence of dissolved silicate, the metakaolin only partially dissolves, as the aluminosilicate gel precipitates on the surfaces of the ...
Precise determination of the elastic properties of soft condensed matter at the nanoscale is important in many situations, from substrate characterization to cancer cell differentiation. When measuring these properties at the nanoscale through contact mechanics, adhesive effects dominate the interaction and prevent obtaining quantitative results. As a solution to this problem, a non-contact measuring mode in liquid has previously been developed for the surface force apparatus (SFA). [1] Advantages of this technique are the non-invasiveness of the measurement and the prevention of probe contamination. SFA measurements are however limited by the macroscopic size of the probe, requiring homogeneous samples and introducing substrate effects in soft films thinner than 300 nm.. To surpass these limits our project has moved the technique to the AFM platform where microscale probes can be utilized, allowing for lateral resolution below the micron scale. In contrast to conventional AFM, the technique is ...
The aim of this thesis work is to study the physico-chemical properties of poly(ethylene oxide), PEO, based brush polymers both in solution and at solid/aqueous interfaces. The importance of studying the surface properties of brush polymers can be related to a broad spectrum of interfacial-related applications such as colloidal stability, lubrication, detergency, protein repellency to name a few. In many applications it is desirable to form brush-like structures through simple physisorption. In this context the surface properties of PEO based brush polymers differing in molecular architecture were studied, using ellipsometry and surface force apparatus (SFA), to gain some understanding regarding the effect of molecular architecture on the formation of brush structures. The molecular architecture was varied by varying the charge/PEO ratio along the backbone. This study demonstrates that the formation of a brush structure at solid/aqueous interface is due to interplay between the attraction of the ...
An abrasive composite is presented having a controlled rate of erosion, the composite comprising abrasive particles dispersed in the binder, wherein the binder comprises an addition polymerized resin having clay particles dispersed therein. The abrasive composite may be adhered to various substrates, including paper, cloth, polymeric films, and nonwovens. The clay particles allow the binder, and thus the composite, to controllably erode upon abrasion of a workpiece, thus exposing fresh abrasive particles to the workpiece. Coatable compositions comprising clay particles dispersed in a binder precursor composition, and optionally containing abrasive particles, are also described, as well as methods of making and using the composites and articles.
Read independent reviews on Aluminosilicate Glass Slides 1000A Gold (Au) over 50A Titanium Adhesion Layer - 1 x 3 x 0.7mm from AMS Biotechnology (Archived Products) on SelectScience
SEM investigation indicates a complex mineral assemblage is present. Subhedral kaolinite and illite commonly coat grains and occur as cement. Fe oxides are present as well. Back-scatter imaging indicates that an unidentified subhedral to anhedral aluminosilicate occurs as does an unusual Ag-bearing aluminum phosphate. Chlorine is also detected in particles near the Ag-bearing aluminum phosphate and this is consistent with low temperature hydrothermal mobilization and deposition of Ag. Some aluminosilicate grains may be detrital however some appear to post date kaolinite and illite mineralization. The Ag-bearing phosphate has textures consistent with late phase mineralization and does post date other textures. Fe-oxides appear to occur as multiple generations. The aluminosilicate may be impact related and if enough sample material can be extracted definitive X-ray investigation will enable phase identification, potentially placing more constraints on impact conditions. Further studies of high ...

Hydrocarbon conversion processes are disclosed which are catalyzed by novel pillared clay compositions. The clay contains pillars which are at least partially fluorided. These pillars are metal fluoro hydroxy cations where the metal can be Al, Zr, Si/Al, Ti or Cr. The clays which can be pillared with these pillars are the smectite clays which include hectorite and beidellite along with synthetically prepared smectite clays. These clays are prepared by pillaring the clay, followed by calcination and then treatment with a fluoride salt such as ammonium bifluoride.
Lab Manager: Dr. Virginia McLemore. Clay Material Testing The NMBGMR has facilities to characterize the mineralogy and ceramic properties of clay materials. Testing capabilities include particle-size distribution analyses to measure the amounts of clay, silt and coarser material present; X-ray diffraction analyses to determine the mineralogy of both bulk-rock samples and clay-size material; and leaching tests to measure the amount of insoluble material present. The results of these tests aid in determining the value of clay materials to the public and industry, and their importance in scientific research. Recent projects of the clay material testing laboratory include the characterization of mine rock piles and soils contaminated by heavy metals. Another important area of study is the evaluation of clay material resources for existing and possible new industries in New Mexico. Although the clay materials laboratory cannot accept outside samples on a regular basis, contract testing is possible on ...
What are the benefits of using it in our fish tanks and ponds? The first main benefit of this clay is in its high mineral content that provides well over 50 macro, micro and trace elements remineralizing the aquatic system. All living organisms, including goldfish, require a constant supply of these elements for various biological processes to function normally. It also improves fish digestion. Second, is its detoxifying effect. The clays particles are so small that the action of water molecules is enough to keep them in suspension or colloidal state. The surface area of particles in one gram of clay can reach almost 10,764 sq.ft (1000 sq.m). Negatively charged clay particles have the ability to trap or flocculate heavy metals, pesticides, free radicals and even virus cells, etc., making them easily removable with mechanical filters and water changes. Third, it accelerates bio filter work by positively affecting nitrifying bacteria, at the same time, based on the article mentioned above, it ...

In order to characterize the petrological and chemical effects of illuviation, we collected 17 samples of saprock adjacent to, and 14 samples of corestone from, an ~6.7 m high tonalitic corestone (tor). Based on thin section observations, all saprock samples are characterized by a network of transgranular and intergranular cracks filled or lined with illuviated clay. In contrast, the silicate framework has been weakly to mildly weathered, and as result, biotite has been partially transformed into mixed-layer biotite/vermiculite, plagioclase has been weakly weathered to a dusting of smectite, and hornblende has been weakly weathered to Fe- and/or Mn-oxyhydroxide. The weathering of biotite translates into an ~5-6% loss of K mass while the weathering of plagioclase resulted in no statistically significant loss of Ca or Na mass.. The above effects of eluviation contrast markedly with the statistically significant additions of Si, Al, Fe, Mn, Ti, Sc, Cr, Cu, Rb, Y, and Yb mass produced by ...

EFEK BO PADA AGREGASI TANAH …. Diunduh dari sumber: 26/10/2012 Bacterial cells with a coat of extracellular polysaccharides (EPS) are enveloped by clay particles. The pore space where clays and bacteria interact, bounded by silt- and sand- size particles, is relatively enriched in organic matter including EPS residues. Fungal hyphae are attached to the outside surface of an aggregate. At normal soil pH conditions, the cell has a net negative surface charge. Most clay particles adhere to the cell surface by bridging through polyvalent cations, represented by M n+ (a) although some may be attached directly by electrostatic interactions, either in face-to-face (b), or edge-to- face (c) association.

The work reported in this thesis builds on research into electrical degradation of mica. The present work is concerned with the study of the deleterious mechanism of partial discharge (PD) induced surface and bulk disruption on mica. Many high voltage (HV) insulation systems incorporate composite materials containing mica as a matrix material. Mica, a naturally occurring mineral possesses attractive thermal, electrical, chemical and physical prope11ies, all highly desirable attributes for successful HV insulation. Investigation of electrical breakdown phenomena in dielectric media is unde11aken before proceeding to the mica - PD study which constitutes the major part of the work High grade Muscovite mica was selected for the experimental work; samples were exposed to four HV electrical stress regimes: AC point-plane, AC m1ificial voids, AC m1ificial vented voids and DC impulse with thermally stressed samples in an ambient air atmosphere. In addition the effect of electrode material and void ...
left-handed. Box 6-1 DNA Has 10.5 Base Pairs per Turn of the Helix in Solution: The Mica Experiment. This value of 10 base pairs per turn vanes somewhat under different conditions. A classic experiment that was earned out in the 1970s demonstrated that DNA absorbed on a surface has somewhat greater than 10 base pairs per turn. Short segments of DNA were allowed to btnd to a mica surface. The presence of 5-terminal phosphates on the DNAs field them in a fixed orientation on the mica. The mica-bound DNAs were then exposed to DNAse I, an enzyme (a rieoxyrifconude-ase) that deaves the phosphodiester bonds in the DNA backbone. Because the enzyme is bulky, it t5 onfy able to deave phosphodiester bonds on the DNA surface furthest from the mica (think of the DNA as a cylinder lying down on a flat surface) due to the stenc difficulty of reaching the sides or bottom, surface of the DNA. As a result, the length of the resulting fragments should reflect the periodicity of the DNA, the number Of base pairs ...

to miss the 3/8 top of the folded paper.. Cut out your printed design (being careful not to touch the image if it is freshly printed). Leave a border of blank paper around the image.. Run white polymer clay through your pasta machine at the thickness you want your piece to be. I used setting #2 (PM2), the second from largest thickness. You need a sheet large enough for your design.. Lay your sheet on your baking surface. If you dont, when you move the piece you risk cracking or distorting the transferred image.. Lay your printed image on the clay with the ink side down (toner actually).. Burnish (rub) the image all over using slight pressure. Dont press so hard that you distort the clay underneath.. When you have rubbed the entire surface of your design very well, lift a corner of the paper. If the paper is not stuck to the clay, burnish it longer.. Grab the corner of your paper and RIP it off in one quick motion.. The ink stays behind, on the surface of the clay.. Trim your clay around ...
To soften polymer clay, hold it in your hands so your body heat can warm it up. If the clay is especially hard, lay a hot water bottle over the clay for about 20 minutes, or microwave it for 10 seconds at a time until it is warm. Once the clay has warmed, knead it with your hands for about a minute, then roll out the clay into a snake shape. The friction from rolling out the clay will help make it soft and pliable. If its too hard to roll out with your hands, try smoothing it out with a rolling pin.
Sub-zeptoliter thermal decomposition of Insulin Fibers. (a) shows a 1x2µm AC (tapping) mode image of insulin fibers deposited on a mica surface. After imaging, a series of thermal-bending compensated, low-temperature thermal cycles were performed in a 12x6 array of points. A small selection of those locations are indicated by the colored markers in both (a) and (b). (b) shows an AC image of the same region after the thermal cycling was complete, showing numerous gaps in the fibers where thermomechanical decomposition has occurred. (c) shows the local thermal expansion (top deflection plots) and resonant frequency shifts (bottom plots) associated with the thermal cycles, color coded by location. Note the clear signal associated with thermal decomposition of the fibers visible in the resonant frequency shift curves. The deflection curves show no significant response at the same temperature. Note that some tip broadening has occurred during the thermal cycling that reduces the resolution between ...
The variation and anisotropy in hydraulic conductivity and the coefficient of consolidation was investigated for two Swedish sulphide clays. A series of constant rate of strain oedometer tests was performed on samples trimmed in the vertical and horizontal direction. A methodology to evaluate the horizontal coefficients of consolidation c h via the horizontal hydraulic conductivity k h and the vertical compression modulus M v is proposed. Laboratory evaluations of c h are also compared with determinations of c h from in situ piezometer measurements in vertically drained sulphide clay. Furthermore, the validity of the empirical correlation between hydraulic conductivity change index C k and initial void ratio e 0, C k = 0.5e 0 (Tavenas et al. in Can Geotech J 20(4):645-660, 1983b), was investigated for the sulphide clays. The results from the investigation show large ranges in measured hydraulic conductivities and coefficients of consolidation. However, the results indicate that the correlation C ...
Clay was totally in his element playing football - a group date tailor-made for him - while Becca and a crowd watched. Toward the end of the game, Clay clinched a touchdown for his team but was immediately on the ground with a noticeable injury. As it turns out, Clay had hurt his wrist badly enough that he had to leave and go to the hospital.. While he returned later in the episode, he told Becca that he had to leave to care for his wrist, which needed immediate surgery. She was visibly upset but understood that his family (and future wife, whoever that may be) depends on him to earn a paycheck by playing football..

Abstract: An experimentally determined Ca-Mg exchange isotherm of montmorillonite is reported. The selectivity coefficient of this exchange over a wide range of Mg saturation was calculated and found constant.. Standard free energies of exchange, thermodynamic equilibrium constants and activity coefficients of the exchangeable Ca and Mg ions in vermiculite and montmorillonite, were predicted from knowledge of the microstructure of these two clays, assuming that coulombic forces are the main ones playing a role in the interaction between the counterions and the charged clay surface. The standard free energies of exchange (ΔG°CaMg = 238 cal/mole) predicted a preference for Ca in montmorillonite and a preference for Mg in vermiculite (ΔG°CaMg = −1665 cal/mole). The predicted thermodynamic equilibrium constants were compatible with the experimentally determined selectivity coefficients KCaMg = 0·67 as compared with KsCaMg = 0·68 in montmorillonite, which remains constant over all the range ...
The ice nucleation characteristics of montmorillonite mineral dust aerosols with and without exposure to ammonia gas were measured at different atmospheric temperatures and relative humidities with a continuous flow diffusion chamber. The montmorillonite particles were exposed to pure (100%) and diluted ammonia gas (25 ppm) at room temperature in a stainless steel chamber. There was no significant change in the mineral dust particle size distribution due to the ammonia gas exposure. 100% pure ammonia gas exposure enhanced the ice nucleating fraction of montmorillonite mineral dust particles 3 to 8 times at 90% relative humidity with respect to water (RHw) and 5 to 8 times at 100% RHw for 120 min exposure time compared to unexposed montmorillonite within our experimental conditions. The percentages of active ice nuclei were 2 to 8 times higher at 90% RHw and 2 to 7 times higher at 100% RHw in 25 ppm ammonia exposed montmorillonite compared to unexposed montmorillonite. All montmorillonite ...

The sorption properties of Transcarpathian clinoptilolite towards Nd(III) and Gd(III) under dynamic condition have been studied. Nd(III) was sorbed with the best efficiency on the uncalcined clinoptilolite samples from the solutions at pH 6.5. Clinoptilolite samples that were previously calcined at 250°C exhibit the maximal sorption capacity towards Gd(III) from the solutions at pH 9.5. Nd(III) and Gd(III) sorption on clinoptilolite mechanisms are different: Nd(III) is sorbed according to the ion-exchange mechanism, and the sorption of Gd(III) is carried out mainly by means of the adsorption of soluble hydrolyzed forms of Gd(III) on the zeolite surface. The differences in sorption mechanisms of these lanthanides give an opportunity to separate Nd(III) and Gd(III) from the solutions at pH 9.5. The maximal sorption capacity of the clinoptilolite regarding Nd(III) and Gd(III) at the optimal conditions was found to be 1810 and 6500 μg/g. The best desorbent of Nd from the clinoptilolite is 7 M ...

Perlite and Vermiculite are two ingredients that are useful for growing plants in the pot or anywhere else. To aerate your soil, any of these two materials can be added to the soil. They allow a good amount of air to reach the roots and thus they are great and extraordinary rooting mediums. They are similar as well as different from each other in their own way. They have their own advantages and disadvantages.. Perlite is basically a volcanic rock and vermiculite is a natural mineral. Both of them expand when exposed to heat and that too at high temperature. Due to this property of Perlite and Vermiculite, they are commercially used for gardening purpose and are popular rooting mediums. To understand both the ingredients, you need to have a clear knowledge about them. Here are some facts about Perlite and Vermiculite.. ...
A mineral lick (also known as a salt lick) is a place where animals can go to lick essential mineral nutrients from a deposit of salts and other minerals. Mineral licks can be naturally occurring or artificial (such as blocks of salt that farmers place in pastures for livestock to lick). Natural licks are common, and they provide essential elements such as phosphorus and the biometals (sodium, calcium, iron, zinc, and trace elements) required in the springtime for bone, muscle and other growth in deer and other wildlife, such as moose, elephants, tapirs, cattle, woodchucks, domestic sheep, fox squirrels, mountain goats and porcupines. Such licks are especially important in ecosystems with poor general availability of nutrients. Harsh weather exposes salty mineral deposits that draw animals from miles away for a taste of needed nutrients. It is thought that certain fauna can detect calcium in salt licks. Many animals regularly visit mineral licks to consume clay, supplementing their diet with ...
Keywords: Diet, feeding, milk yield, zeolita. Abstract: Objective. To determine the efficiency of clinoptilolite supplements on milk production and somatic cell count (SCC). Materials and methods. 80 Holstein-Friesian cows were used, between 2 and 4 years of age ad between their first and third lactation. Two groups made up of 40 animals were constituted, and one of the following treatments were assigned randomly: Control group (n=40) with a basal diet, and experimental group (Clinoptilolite; n=40) with a basal diet + 3% (p/p) of clinoptilolite. The basal diet consisted of corn, hay, sunflower flour, barley grains, wheat bran and soy flour. The experiment lasted 16 weeks (February to June 2013) and began 4 weeks before the expected delivery date. 2560 milk samples were taken (morning and evening), and the farm was visited twice a week. Results. The mean values for the control group and the clinoptilolite group were 30.63±0.851 and 33.66±0.756, respectively. Milk prouction for the ...
Co-adsorption of norfloxacin (Nor) and Cu(II) on montmorillonite at pH 4.5, 7.0 and 9.0 was studied by integrated batch adsorption experiments and extended X-ray absorption fine structure (EXAFS) spectroscopy. Under such pH conditions the dominant species of Nor are cation (Nor+), zwitterion (Nor±), and anion (Nor−), respectively. Results indicated that Nor sorption decreased with an increase of solution pH. The presence of Cu(II) slightly suppressed the Nor+ sorption at pH 4.5, while increased Nor± and Nor−sorption on montmorillonite at pH 7.0 and 9.0, respectively. In contrast, Nor increased Cu(II) adsorption at pH 4.5, but had little effect on the adsorption of Cu(II) on montmorillonite at pH 7.0 and 9.0. Spectroscopic results showed that, at pH 4.5, Nor+ was sorbed on montmorillonite by the formation of outer-sphere montmorilloniteNorCu(II) ternary surface complex. At pH 7.0, montmorilloniteNorCu(II) and montmorilloniteCu(II)Nor ternary surface complexes co-exist. At pH 9.0, ...

Two clay minerals of the similar 2 : 1 layer structure and chemical composition, vermiculite and montmorillonite, were studied using a wide spectrum of experimental methods in their original states and the magnetically modified states after mixing with microwave-synthesized iron oxide particles. This magnetic modification led to different microstructural morphology influencing magnetic behaviour at room and more pronounced at low temperatures.
Molecular dynamics and reverse Monte Carlo simulations are used to investigate the structure of calcium aluminosilicate glasses with low silica content. The polymerized network is close to that expected from a random distribution for all compositions with important amount of Al-O-Al linkages. Minor species such as triclusters and free oxygen atoms are present. The main structural variations are the changes in the ring size distribution or the Qn distribution. The ring statistics indicate the presence of 4-membered rings, with larger rings at high silica content. We observe that Al enters preferentially the tetrahedral polymerized units with increasing SiO2. A noteworthy structural property of the structure of these glasses is the presence of a significant amount of non-bridging oxygens, even in the fully charge-compensated glasses. The Ca environment correspond to a distorted polyhedra with seven oxygen neighbors. The variation of the glass transition temperature of these glasses are explained based on

This is a bit of a long read but very much worth it! Read it and learn!. Far removed from prominent view, exists an age old substance in nature, known as Calcium Montmorillonite Clay. There are only a limited number of Calcium Montmorillonite Clay deposits around the world. The first site was discovered in Montmorillon, France in the 1800s, hence the name, Montmorillonite. For centuries Native American healers used it internally and externally in the treatment of a variety of illnesses. In years past sailing vessels departing from France were known to store clay on board for the treatment of dysentery as well as other ailments. Animals, domestic and wild alike, instinctually drawn to clay deposits have been observed licking the clay as part of their everyday diet, and rolling in it to obtain relief from injuries.. A recognized detoxifying agent, nutrient and bactericidal Calcium Montmorillonite Clay is in the smectite group of clays. Only those clays within the smectite group have the ...
The stability of montmorillonlte colloid dispersion has been studied by measuring the viscosity and Zeta-potential of the colloid dispersions. Results show that they are higher for Na-montmorillonite than for Ca-montmorillonite, suggestlng that the former is expected to show a greater tendency of dispersion. In mixed Na/Ca-montmorillonite the replacement of 10% absorbed Ca~(2+) by Na~+ will increase the viscosity and Zeta-potential. When the exchangeable sodium ion of montmorillonite colloids reaches a value of about 50-60% of ECP the viscosity and Zeta-potential will be close to those of pure Na-collolds,which means the double layer thickness of the colloids approximates that of pure Na-colloids. It has also been shown that the viscosity and Zeta-potential of montmorillonite colloid dispersion are closely related to the kind of exchangeable cations. In montmorillonite colloids they increase with increasing concentration of electralytes (NaCl, Na_2CO_3 and Na_2C_2O_4) in the dispersion. Also, they are

DNA is the bio-polymer containing the genetic information needed for the development and functioning for all living organisms. It has a polymeric structure consisting of units called nucleotides, each consisting of a non-polar, hydrophobic interior (the base pairs) and polar, hydrophilic exterior which is negatively charged due to the phosphate groups along the backbone of the DNA. Its heterogeneous properties permit DNA molecule to interact with other molecules and different types of substrates at the same time. It is important to understand the DNA morphology on flat surface that serves as a template for DNA based sensors and microarray applications, particularly under an electric field. Taken together, the ability to deposit a single DNA molecule on the electrode is essential to increase its specificity. In our study, we optimize the conditions in order to control a single DNA molecule adsorbing and desorbing to/from the electrode. Simultaneously dynamic imaging enables us to analyze its ...

The process of separating the phosphate rock from the matrix is known as beneficiation and produces two waste products, quartz sand and phosphatic clay. The quartz sand is disposed of by pumping it back to mined-out cuts left during the mining process. The phosphatic waste clay is near collodial size material, 0.002 mm in particle size, and has a tendency to remain in suspension for long periods of time when mixed with water. As the clay wastes mixed with water leave the beneficiation plant, the slurry is about three percent solids by weight. The clay wastes are composed of montmorillonite(smectite), attapulgite (palygorskite), kaolinite, illite, phosphate minerals, and silt size material. All of the above clay minerals occur in a complex combination in the natural state and causes numerous varation in settling characteristics of phosphatic clays (USBM, p. 17, 1983). The USBM (p. 17, 1983) states that the phosphatic clays containing greater amounts of attapulgite settle much slower than those ...

Vermiculite is commonly cited as an ingredient in different soils, like potting soil. But what is vermiculite and why is it used?
Mineral licks are muddy depressions maintained by larger Neotropical mammals, such as peccaries and tapirs. Quite often, these mineral licks are visited by dozens and hundreds of fruit-eating bats at night (Voigt et al. 2007). Interestingly, most of these bats are pregnant and lactating females. What are these bats doing at mineral licks? Growing evidence accumulates that they consume muddy water; but for what reason? We have formulated two hypotheses that are not mutually exclusive: Nutrient supplementation and detoxification (Voigt et al. 2008).

The saturation index of clay minerals like Gibbsite, Kaolinite, Illite, Montmorillonite and Chlorite in groundwater were studied in detail by collecting 29 groundwater samples from the shallow coastal aquifers in and around Kalpakkam. The samples collected were analysed for major cations, anions and trace elements by using standard procedures. The study reveals that pH has a significant role in the saturation index (SI) of minerals. It also shows that the relationship of electrical conductivity to the SI of these minerals is not significant than that of the ionic strength, log pCO2 values, and alumina silica ratio have significant relation to the SI of these clay minerals. The SI of these clay minerals was spatially distributed to identify the areas of higher SI. Silica has good correlation to SI of Kaolinite, Gibbsite and Montmorillonite and Al has good correlation to SI of all the minerals except to that of Chlorite.. ...

It is now well admitted that hydrophobic interactions and hydrogen bonds are the main forces driving protein folding and stability. However, because of the complex structure of a protein, it is still difficult to separate the different energetic contributions and have a reliable estimate of the hydrogen bond part. This energy can be quantified on simpler systems such as surfaces bearing hydrogen-bonding groups. Using the surface force apparatus, we have directly measured the interaction energy between monolayers of lipids whose headgroups can establish hydrogen bonds in water: nitrilotriac-etate, adenosine, thymidine, and methylated thymidine lipids. From the adhesion energy between the surfaces, we have deduced the energy of a single hydrogen bond in water. We found in each case an energy of 0.5 kcal/mol. This result is in good agreement with recent experimental and theoretical studies made on protein systems showing that intramolecular hydrogen bonds make a positive contribution to protein

Clay minerals formed through chemical weathering have long been implicated in the burial of organic matter (OM), but because diagenesis and metamorphism commonly obscure the signature of weathering-derived clays in Precambrian rocks, clay mineralogy and its role in OM burial through much of geologic time remains incompletely understood. Here we have analyzed the mineralogy, geochemistry and total organic carbon (TOC) of organic rich shales deposited in late Archean to early Cambrian sedimentary basins. Across all samples we have quantified the contribution of 1M and 1Md illite polytypes, clay minerals formed by diagenetic transformation of smectite and/or kaolinite-rich weathering products. This mineralogical signal, together with corrected paleo-weathering indices, indicates that late Archean and Mesoproterozoic samples were moderately to intensely weathered. However, in late Neoproterozoic basins, 2M1 illite/mica dominates clay mineralogy and paleo-weathering indices sharply decrease, ...
