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 ...

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.

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 ...
Feldspars melt into a glass like consistency, and flow, like a thick liquid at high temperature. A clay containing too much feldspar would be unsuitable as a potters clay since objects made from it would simply melt into a puddle in the kiln instead of maintaining the desired shape. Most potters clays contain no more than 15% feldspar, but porcelain clays may contain up to 25%. The other 75% is made up of non-melting refractory materials. Some glazes, on the other hand, contain up to 100% feldspar, since the purpose of a glaze is to melt and flow over the surface of the clay body.. Feldspars melt at about 1150 degrees C. The feldspathic glass they produce surrounds the refractory clay particles and fills up the pores between them. Due to the free fluxes they contain, feldspathic glasses will also bind to the surfaces of the refractory particles thus helping to bind the ceramic body together. The more feldspathic glass a ceramic body contains, the denser the fired body will be. Each of the three ...

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 ...
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.

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.
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. (Sumber: Theng and Orchard (1995).

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 ...
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.
... is a coarse-grained intrusive igneous rock of the same general composition as granite but with the quartz either absent or present in relatively small amounts (,5%).. The feldspar component of syenite is predominantly alkaline in character (usually orthoclase) . Plagioclase feldspars may be present in small quantities, less than 10%.. When present, ferromagnesian minerals are usually hornblende amphibole, rarely pyroxene or biotite. Biotite is rare, because in a syenite magma most aluminium is used in producing feldspar.. Syenites are usually peralkaline and peraluminous, with high proportions of alkali elements and aluminium.. Syenites are formed from alkaline igneous activity, generally formed in thick continental crustal areas, or in Cordilleran subduction zones. To produce a syenite, it is necessary to melt a granitic or igneous protolith to a fairly low degree of partial melting. This is required because potassium is an incompatible element and tends to enter a melt first, whereas ...
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).

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 ...

Dwyer testified that while he had initially expressed doubts about his identification of Clay, telling police he "wasnt ready to say thats the guy," he said his pre-hypnosis certainty was eight on a scale of one to 10. Dwyer testified that 11 days after the shooting, he agreed to be hypnotized a second time. During this session, he said, he saw the "film of what occurred." When the men get into Boyajians cab, the film was "frozen with a frame on the screen," and the screen zoomed in so that he could get "a close-up view of the faces of the three individuals." Dwyer even claimed that he got a "closer view" than he had from his cab.

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 ...

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.

The porous properties of silica prepared from heat-treated Transvaal vermiculite (South Africa) by acid leaching were determined. The effect of temperature on the destruction of the crystal structure of the vermiculite was determined, leading to the adoption of heating conditions of 600 o C for 2 h which produce a fully amorphous sample. The heat-treated samples were leached with 2M hydrochloric acid at 80 o C for 0.5, 2 and 8 h and their porous properties were characterized by measuring their specific surface areas and pore volumes. The highest surface area and pore volume (559 m2/g and 0.51 ml/g) was obtained for the sample leached for 8 h. Thermal amorphisation of vermiculite exerts a negative influence on the porous properties of the mineral.. ...

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 present invention provides a process for modifying a crystalline aluminosilicate zeolite having a Constraint Index of from about to about 12 which comprises: a) steaming the as synthesized crystalline aluminosilicate zeolite containing organic template material to decompose at least a portion of said template material and to extract zeolitic aluminum; and, b) contacting the zeolite resulting from step (a) in the ammonium, alkali metal or hydrogen form with a dealuminizing agent which forms a water-soluble complex with aluminum to remove a further quantity of zeolitic aluminum therefrom.
At its peak, the Libby mine may have provided 80 percent of the worlds vermiculite, most of which was contaminated with what would become known as Libby Amphibole Asbestos. The contamination was not limited just to the mine site; Libby residents were able to pick up free truckloads of asbestos-contaminated vermiculite for use at home. The vermiculite was used to pave driveways and in public areas (boat ramps, ice rink, running track, baseball fields and school yards). Children played in piles of vermiculite that could be found throughout the community. Also, attic insulation contaminated with Libby asbestos may still be in schools, businesses and as many as 35 million homes around the United States alone ...
Four clays were treated with each of eight surfactants at three treatment rates. Volclay and the clay fraction from two montmorillonitic soils were treated with 100, 50, and 10 mmol /100 g.; and kaolinite was treated with 10, 5, and 1 mmol /100g.. Adsorption was measured quantitatively by the thermogravimetric method. Adsorption mechanisms were investigated by X-ray diffraction and differential thermal analysis.. The surfactants included three anionic, three cationic, and two nonionic compounds. The anionics were not adsorbed in appreciable quantities and anion exchange of kaolinite appeared to be equal to or somewhat greater than that of montmorillonite. Anionics had no effect on the d-spacing of montmorillonite and did not interfere with hydration of clay surfaces.. Cationics were strongly adsorbed by the clay surfaces through ionic bonding in amounts equal to or even greater than the cation-exchange capacities of the clays. The excess material was probably held by van der Waals forces between ...
The purpose of this study was to quantify and compare the amount of water absorbed by six commercially available resin-modified glass ionomer cements and to investigate the possible influence of time and resin content on water sorption. The materials evaluated included Variglass used as a restoration, base and liner; Fuji II LC; Fuji Liner; Vitrebond; Vitremer and Photac-Bond. Z100, a composite resin, was used as control. All specimens were manipulated according to manufacturers instructions and then subjected to a water sorption test based on the ISO 4049 requirements. Storage in water was further extended to 1 month to evaluate the effects of time and indirectly cement maturity on water sorption. Data were subjected to one-way ANOVA and Duncans test at 0.05 significance level. Results show that the composite resin control had significantly less water sorption than all the resin-modified polyalkenoate cements evaluated. Variglass when used as a base or restorative had the least water sorption ...
Attapulgite clay also known as palygorskite is a mineral clay which possess good adsorption properties based on its adsorption capacity, porous structure and moderate cation exchange properties. The study investigated the effectiveness of naturally occurring and hydrochloric acid modified attapulgite as adsorbents for Cr (VI) remediation in wastewater. The physical properties of the clay were characterized using a range of techniques. X-ray diffraction confirmed the purity of the clay while BET analysis indicated an increase in surface area from 131.4 to 183.2 m2/g after acid modification. The modified attapulgite was predicted to have an adsorption capacity of 75 mg/g compared to 2.1 mg/g for the naturally occurring attapulgite. The increase in adsorption capacity was attributed to a change in surface area as well as changes in the surface chemistry of the clay. The adsorption isotherms were best described by the Langmuir mono-layer adsorption model while the kinetics fit the Langren first ...
In this study, thermoplastic poly(ester ether) elastomer (TPEE) nanocomposites with phosphorus-nitrogen (P-N) flame retardants and montmorillonite (MMT) were prepared by melt blending. The fire resistance of the nanocomposites was analyzed by limiting oxygen index (LOI) and vertical burning (UL 94) tests. The results show that the addition of the P-N flame retardants increased the LOI of the material from 17.3 to 27%. However, TPEE containing P-N flame retardants only obtained a UL 94 V-2 ranking; this resulted in a flame dripping phenomenon. On the other hand, TPEE containing the P-N flame retardant and organically modified montmorillonite (o-MMT) achieved better thermal stability and good flame retardancy; this was ascribed to its partially intercalated structure. The synergistic effect and synergism were investigated by Fourier transform infrared spectroscopy and thermogravimetry. The introduction of o-MMT decreased the inhibition action of the P-N flame retardant and increased the amount of ...
0010] Inventors of the present invention conducted intensive studies on an inorganic filler and a resin composition in order to provide an adhesive material having sufficient adhesiveness and sufficient heat resistance. As a result, the inventors found that a layered clay mineral dispersed in an adhesive agent does not undergo complete interlayer separation, but the layered clay mineral is dispersed in the adhesive agent with its layers being in a stacked state. Therefore, the resulting adhesive composition suffers from variations in physical properties. Further, the inventors found that, where an adhesive tape is produced by using the adhesive composition, stress is liable to be concentrated on peripheries of particles of the layered clay mineral in the adhesive agent during peel-off of the adhesive tape, resulting in cohesive failure of the adhesive agent. As a result of further studies, the inventors found that, where an organophilic layered double hydroxide (B) organically treated with an ...
Respirable particles of high-percentage silica content from anthracite and bituminous coal mine dust samples were analyzed for aluminosilicate clay surface coating, by measuring silicon and aluminum X-ray spectra using scanning electron microscopy-energy dispersive X-ray analysis (SEM-EDS). Silicon and aluminum elemental ratios were determined with incident electron energies of 20 and 5 keV to reveal whether surface occlusion was present. Some 20 respirable-sized, non-agglomerated particles with silicon fraction of signal of 75% or more (for elements above sodium) were analyzed for each of 12 coal mine dust samples. Mine dust samples were from U.S. anthracite and bituminous coal mining regions involved in epidemiological studies of the U.S. National Study of Coal Workers Pneumoconiosis. Some particles of high-percentage silica content exhibited a decrease in the ratio of silicon-to-aluminum K-alpha line intensities with decreasing electron beam accelerating voltage, consistent with aluminosilicate clay
