Comparative evaluation of two density gradient preparations for sperm separation for medically assisted conception. (1/455)

To evaluate and optimize the sperm separation efficiency of a novel silane-coated silica bead (Puresperm), serial studies were carried out to compare the various sperm parameters between: (i) three-layer (90%-70%-40%) Puresperm and three-layer (90%-70%-40%) conventional polyvinylpyrrolidone (PVP)-coated silica bead (Percoll) gradients; (ii) three-layer (90%-70%-40%) and two-layer (90%-45%) Puresperm gradients and separately the same for Percoll; and (iii) large (3.0 ml) and small (0.75 ml) semen loading volumes on three-layer Puresperm gradients. Normozoospermic semen samples were treated and analysed in 12 replicates for each experiment. Manual evaluation of concentration, percentage motility, percentage vitality, percentage normal morphology; computer-assisted semen analysis evaluation of concentration, percentage motility, grade of motility, motion characteristics (curvilinear velocity, linearity, amplitude of lateral head velocity, beat cross frequency, percentage hyperactivation); and yields from the initial semen samples were compared. Percoll was found to be superior to Puresperm in concentration, percentage motility, percentage vitality and yields after three-layer density gradient centrifugation. There were no significant differences in sperm parameters between two- and three-layer Percoll gradients, but three-layer Puresperm gradients behaved significantly better than two-layer gradients. Large semen volume loads on three-layer Puresperm gradients resulted in greater sperm concentrations, percentage motility, percentage vitality and percentage normal morphology, but small semen volume loads produced greater yields of good-quality spermatozoa. In the light of Percoll being withdrawn from the shelf for the use of assisted reproduction because of the presence of PVP, three-layer Puresperm gradients with large semen loading volumes appear to be an attractive alternative for sperm separation in medically assisted conception.  (+info)

Cationic silanes stabilize intermediates in DNA condensation. (2/455)

In vitro condensation of DNA has been widely studied to gain insight into the mechanisms of DNA compaction in biological systems such as chromosomes and phage heads and has been used to produce nanostructured particles with novel material and functional properties. Here we report on the condensation of DNA in aqueous solutions by cationic silanes, which combine the condensing properties of polyamines with the cross-linking chemistry of silanes. DNA can be reversibly condensed into classical toroidal and rod-shaped structures with these agents. At low silane concentrations DNA forms a variety of looped structures with well-defined characteristics, including flower- and sausage-shaped forms. These structures suggest that at low silane concentrations a DNA-DNA contact in which the strands are at very large angles to each other is stabilized. Changes in these structures observed as a function of silane concentration suggest possible pathways for the formation of toroids and rods.  (+info)

Factors affecting the shear bond strength of orthodontic brackets to porcelain. (3/455)

The aim of this investigation was to establish a regime for orthodontic bonding to feldspathic porcelain, which ensures adequate bond strength (6-8 MPa) with minimal damage on debond and consisted of an ex vivo investigation measuring the effects of porcelain surface preparation and thermocycling on shear bond strength of orthodontic brackets. One-hundred-and-twenty feldspathic porcelain bonded crown surfaces were divided into 12 equally-sized groups to assess the effects of: (1) glaze removal, (2) application of hydrofluoric acid, phosphoric acid, or omission of acid treatment, and (3) silane priming upon the bond strength of premolar brackets bonded with Right-on (TM) composite resin adhesive. Specimens were subjected to thermocycling and then to shear debonding forces on an Instron machine. Removal of the porcelain glaze, or use of hydrofluoric acid, prior to bonding were found to be unnecessary to secure the target bond strength. Hydrofluoric acid application was associated with increased porcelain surface damage. Thermocycling caused a significant reduction in shear bond strength to porcelain (P < 0*001). The best regime for orthodontic bonding to feldspathic porcelain was to apply phosphoric acid for 60 seconds, and prime with silane prior to bonding. Usually the porcelain surfaces could be repolished. Refereed Paper  (+info)

Relationships among cell attachment, spreading, cytoskeletal organization, and migration rate for anchorage-dependent cells on model surfaces. (4/455)

Many research and commercial applications use a synthetic substrate which is seeded with cells in a serum-containing medium. The surface properties of the material influence the composition of the adsorbed protein layer, which subsequently regulates a variety of cell behaviors such as attachment, spreading, proliferation, migration, and differentiation. In this study, we examined the relationships among cell attachment, spreading, cytoskeletal organization, and migration rate for MC3T3-E1 osteoblasts on glass surfaces modified with -SO(x), -NH(2), -N(+)(CH(3))(3), -SH, and -CH(3) terminal silanes. We also studied the relationship between cell spread area and migration rate for a variety of anchorage-dependent cell types on a model polymeric biomaterial, poly(acrylonitrile-vinylchloride). Our results indicated that MC3T3-E1 osteoblast behavior was surface chemistry dependent, and varied with individual functional groups rather than general surface properties such as wettability. In addition, cell migration rate was inversely related to cell spread area for MC3T3-E1 osteoblasts on a variety of silane-modified surfaces as well as for different anchorage-dependent cell types on a model polymeric biomaterial. Furthermore, the data revealed significant differences in migration rate among different cell types on a common polymeric substrate, suggesting that cell type-specific differences must be considered when using, selecting, or designing a substrate for research and therapeutic applications.  (+info)

The use of silane-coated silica particles for density gradient centrifugation in in-vitro fertilization. (5/455)

Silane-coated silica particles (PureSperm) were evaluated as an alternative to Percoll for gradient separation of spermatozoa, for use in assisted reproduction. Recovery of motile and morphologically normal spermatozoa after using a four-layer Percoll and a two- and four-layer PureSperm gradient respectively was recorded. In-vitro fertilization (IVF) results after using PureSperm for the sperm preparation were also evaluated. No difference in sperm recovery or sperm motility was found when comparing the use of Percoll and the four-layer gradient of PureSperm. When using a two-layer PureSperm gradient, motility was significantly decreased (P < 0.05) compared to Percoll. Normal sperm morphology increased from 8-17.2% after using Percoll and to 12.7% and 11.4% after using a four-layer and a two-layer PureSperm gradient respectively. All gradient preparations showed a significant decrease in the teratozoospermia index compared to the ejaculate (P < 0.01). No significant differences in IVF results regarding fertilization and pregnancy rates were found when PureSperm or the swim-up technique were used for the sperm preparation. PureSperm seems to be an acceptable alternative to Percoll but although the percentage of sperm recovery was higher after PureSperm we still recommend the swim-up technique to be the first choice, as a higher percentage of progressive motile spermatozoa is obtained without using other chemicals than IVF culture medium.  (+info)

Photodynamic therapy with the phthalocyanine photosensitizer Pc 4 of SW480 human colon cancer xenografts in athymic mice. (6/455)

Photodynamic therapy (PDT) using the silicon phthalocyanine photosensitizer Pc 4 [HOSiPcOSi(CH3)2(CH2)3N-(CH3)2] is an oxidative stress associated with induction of apoptosis in various cell types. We assessed the effectiveness of Pc 4-PDT on SW480 colon cancer xenografts grown in athymic nude mice. Animals bearing xenografts were treated with 1 mg/kg body weight Pc 4 and 48 h later were irradiated with 150 J/cm2 672-nm light from a diode laser delivered at 150 mW/cm2. Biochemical studies were performed in xenografts resected at various time points up to 26 h after Pc 4-PDT treatment, whereas tumor size was evaluated over a 4-week period in parallel experiments. In the tumors resected for biochemical studies, apoptosis was visualized by activation of caspase-9 and caspase-3 and a gradual increase in the cleavage of the nuclear enzyme poly(ADP-ribose) polymerase (PARP) to a maximum of approximately 60% of the total PARP present at approximately 26 h. At that time all Pc 4-PDT-treated tumors had regressed significantly. Two signaling responses that have previously been shown to be associated with Pc 4-PDT-induced apoptosis in cultured cells, p38 mitogen-activated protein kinase and p21/WAF1/Cip1, were examined. A marked increase in phosphorylation of p38 was observed within 1 h after Pc 4-PDT without changes in levels of the p38 protein. Levels of p21 were not altered in the xenografts in correspondence with the presence of mutant p53 in SW480 cells. Evaluation of tumor size showed that tumor growth resumed after a delay of 9-15 days. Our results suggest that: (a) Pc 4-PDT is effective in the treatment of SW480 human colon cancer xenografts independent of p53 status; (b) PARP cleavage may be mediated by caspase-9 and caspase-3 activation in the Pc 4-PDT-treated tumors; and (c) p38 phosphorylation may be a trigger of apoptosis in response to PDT in vivo in this tumor model.  (+info)

Silanized nucleic acids: a general platform for DNA immobilization. (7/455)

We have developed a method for simultaneous deposition and covalent cross-linking of oligonucleotide or PCR products on unmodified glass surfaces. By covalently conjugating an active silyl moiety onto oligonucleotides or cDNA in solutions we have generated a new class of modified nucleic acids, namely silanized nucleic acids. Such silanized molecules can be immobilized instantly onto glass surfaces after manual or automated deposition. This method provides a simple and rapid, yet very efficient, solution to the immobilization of prefabricated oligonucleotides and DNA for chip production.  (+info)

Tethered polymer-supported planar lipid bilayers for reconstitution of integral membrane proteins: silane-polyethyleneglycol-lipid as a cushion and covalent linker. (8/455)

There is increasing interest in supported membranes as models of biological membranes and as a physiological matrix for studying the structure and function of membrane proteins and receptors. A common problem of protein-lipid bilayers that are directly supported on a hydrophilic substrate is nonphysiological interactions of integral membrane proteins with the solid support to the extent that they will not diffuse in the plane of the membrane. To alleviate some of these problems we have developed a new tethered polymer-supported planar lipid bilayer system, which permitted us to reconstitute integral membrane proteins in a laterally mobile form. We have supported lipid bilayers on a newly designed polyethyleneglycol cushion, which provided a soft support and, for increased stability, covalent linkage of the membranes to the supporting quartz or glass substrates. The formation and morphology of the bilayers were followed by total internal reflection and epifluorescence microscopy, and the lateral diffusion of the lipids and proteins in the bilayer was monitored by fluorescence recovery after photobleaching. Uniform bilayers with high lateral lipid diffusion coefficients (0.8-1.2 x 10(-8) cm(2)/s) were observed when the polymer concentration was kept slightly below the mushroom-to-brush transition. Cytochrome b(5) and annexin V were used as first test proteins in this system. When reconstituted in supported bilayers that were directly supported on quartz, both proteins were largely immobile with mobile fractions < 25%. However, two populations of laterally mobile proteins were observed in the polymer-supported bilayers. Approximately 25% of cytochrome b(5) diffused with a diffusion coefficient of approximately 1 x 10(-8) cm(2)/s, and 50-60% diffused with a diffusion coefficient of approximately 2 x 10(-10) cm(2)/s. Similarly, one-third of annexin V diffused with a diffusion coefficient of approximately 3 x 10(-9) cm(2)/s, and two-thirds diffused with a diffusion coefficient of approximately 4 x 10(-10) cm(2)/s. A model for the interaction of these proteins with the underlying polymer is discussed.  (+info)

Nuclear Magnetic Resonance Studies of the Hydrolysis and Molecular Mot by Hye-Jung Kang, Wiriya Meesiri et al.Nuclear Magnetic Resonance Studies of the Hydrolysis and Molecular Mot by Hye-Jung Kang, Wiriya Meesiri et al.
The hydrolysis and dynamics of silane coupling agents have been probed using nuclear magnetic resonance (NMR) spectroscopy. The hydrolysis of γ-aminopropyltrimethoxysilane and γ-aminopropyltriethoxysilane were studied using proton NMR spectroscopy. The rates of hydrolysis were dependent on the water and silane coupling agent concentration as well as their chemical nature. The methoxy-substituted silane hydrolyzed much faster than the ethoxy-substituted one. The molecular motion of γ-aminopropylsilane-d2 immobilized on a silica surface and as the bulk polymerized siloxane were characterized by 2H solid-echo NMR techniques. It was found that the motion of the silane coupling agent on silica was more restricted than in the condensed polymer. Deuterium oxide exchange experiments also showed that the motion of deuterons on the amino group is much faster than those of the deuterons on the methylene group in silane coupling agents. © 1990.

Altering Ion Transport Across Alumina Nanotube Membranes by Sai Sumana PenumetchaAltering Ion Transport Across Alumina Nanotube Membranes by Sai Sumana Penumetcha
This research project examines the transport of ions through porous alumina membranes with channels of ̃200 nanometers in diameter. The test molecule is the permeate anion 1,5-naphthalene disulfonate (NDS2-), which as absorbance in the ultraviolet range and also exhibits fluorescence. This allows direct examination of transport by utilizing ultraviolet-visible spectroscopy as well as fluorescence spectroscopy. Adding substituents through strong alumina-silane linkages further modifies all the surfaces of the alumina nanotube membranes. Membranes are soaked in solutions containing either octadecyl trimethoxysilane (ODTMS) or isobutyl trimethoxysilane (IBTMS). Ion transport across the membrane treated with the hydrophobic octadecyl trimethoxysilane was hindered significantly, while the membranes exposed to a short alkyl chain isobutyl trimethoxysilane demonstrated only a slight blockage of ion transport.

Reed and wheat straw particleboards bonded with urea formaldehyde (UF) resin were manufactured from two different material configurations (i.e., fine and coarse particles). The board densities were in the range of 0.550-.90g/cm3. The effects of particle size and board density on the board properties were examined. The properties of particleboard produced from fine particles were better than those made from coarse particles. An increase in board density resulted in a corresponding improvement in the board properties. The properties of OF bonded reed and wheat straw particleboards were relatively lower than those of commercial particleboards. Three silane coupling agents were used to improve the bondability between the reed and wheat particles and OF resin. Results of this study indicate that all the board properties were improved by the addition of silane coupling agent. The degree of improvement achieved from each coupling agent was different; epoxide silane was found to be more effective for reed straw

decachlorotetrasilane - Registration Dossier - ECHAdecachlorotetrasilane - Registration Dossier - ECHA
There are no reliable short-term data available for decachlorotetrasilane (CAS 13465-77-5), therefore good quality data for appropriate structural analogues, trimethoxysilane (CAS 2487-90-3) and tetraethyl orthosilicate (CAS 78-10-4), have been read across. All substances share the same silanol hydrolysis product, monosilicic acid. The other hydrolysis products are hydrogen chloride for decachlorotetrasilane, methanol for trimethoxysilane and ethanol for tetraethyl orthosilicate. A 72-h EC50 value of ,100 mg/l (nominal) (highest concentration tested) and NOEC of ,6.3 mg/l (nominal) have been determined for the effects of trimethoxysilane (CAS 2487-90-3) on growth rate and biomass of Pseudokirchneriella subcapitata.

Treatment of the complex Mo(NO)Cl3(NCMe)2 with the large bite angle diphosphine, 2,2′-bis(diphenylphosphino)diphenylether (DPEphos) afforded the dinuclear species [Mo(NO)(P∩P)Cl2]2[μCl]2 (P∩P = DPEphos = (Ph2PC6H4)2O (1). 1 could be reduced in the presence of Zn and MeCN to the cationic complex [Mo(NO)(P∩P)(NCMe)3]+[Zn2Cl6]2-1/2 (2). In a metathetical reaction the [Zn2Cl6]2-1/2 counteranion was replaced with NaBArF4 (BArF4 = [B{3,5-(CF3)2C6H3}4]) to obtain the [BArF4]− salt [Mo(NO)(P∩P)(NCMe)3]+[BArF4]− (3). 3 was found to catalyze hydrosilylations of various para substituted benzaldehydes, cyclohexanecarboxaldehyde, 2-thiophenecarboxaldehyde, and 2-furfural at 120 °C. A screening of silanes revealed primary and secondary aromatic silanes to be most effective in the catalytic hydrosilylation with 3. Also ketones could be hydrosilylated at room temperature using 3 and PhMeSiH2. A maximum turnover frequency (TOF) of 3.2 × 104 h-1 at 120 °C and a TOF of 4400 h-1 was obtained at ...

Cell Density Cell densities in the 31, 63, 130, 250, 500 and 1000 mg a.i./L treatment levels averaged 83, 136, 137, 89, 11 and 0 x 10E4 cells/mL, respectively. Statistical analysis based on Williams Test determined a significant reduction in cell density in all treatment level tested as compared to the pooled control. Based on Williams Test the NOEC was determined to be ,31 mg a.i./L. Additional statistical analysis (Bonferronis Test) determined a significant reduction in cell density in the 31, 250, 500 and 1000 mg a.i./L treatments. The effect on the 31 mg a.i./L treatment level is not considered treatment-related since the two higher concentrations (63 and 130 mg a.i./L) were not affected and were less than 10% inhibited. Therefore, the NOEC was determined to be 130 mg a.i./L. The 96 hour EC50 for cell density was calculated to be 260 mg a.i./L, with 95% confidence intervals of 190 and 360 mg a.i./L.

The chloro and azido complexes trans-[PdCl(4-C5NF4)(PiPr(3))(2)] ( 3) and trans-[Pd(N-3)(4-C5NF4)(PiPr(3))(2)] ( 4) can be prepared by reaction of [PdF(4-C5NF4)(PiPr(3))(2)] ( 2) with Et3SiCl or MeSiN3, respectively. In contrast, reactions of 2 with Ph3SiH or Me2FSiSiFMe2 give the products of reductive elimination 2,3,5,6-tetrafluoropyridine ( 5) or 4-(fluorodimethylsilyl) tetrafluoropyridine ( 6) as well as [Pd(PiPr(3))(2)] ( 1). In a catalytic experiment, pentafluoropyridine can be converted with Ph3SiH into 5 in 62% yield, when 10% of 2 is employed as catalyst. Treatment of trans-[PdF(4-C5NF4)(PiPr(3))(2)] ( 2) with Bu3SnCH=CH2 in THF at 50 degrees C results in the formation of [Pd(PiPr(3))(2)] ( 1) and 4- vinyltetrafluoropyridine ( 7). Complex 2 is also active as a catalyst towards a Stille cross-coupling reaction of pentafluoropyridine with Bu3SnCH= CH2 to give 4-vinyltetrafluoropyridine ( 7) with a TON of 6.

N2 - The catalytic hydrosilylation of aldehydes in the presence of PBu3 modified Au(I)-complexes was investigated. In situ IR and NMR experiments have revealed that both, the ligand PBu3 and the substrate aldehyde play an important role in stabilizing the gold catalyst and/or forming the catalytically active species. In their absence the reducing power of silane destabilizes the gold (I) catalyst giving rise to gold clusters or particles. Several side reactions involving water and oxygen were also investigated. A plausible reaction pathway as an alternative to the well-accepted mechanism for the transition-metal homogeneously catalyzed hydrosilylation of aldehydes has been proposed to accommodate the experimental observations..

Leicester Research Archive: Some reactions of organogermanium compounds.
A comparative survey of published work on the reactions of organic derivatives of the Group IVB elements has been made, and the function of these elements in such reactions is discussed. The influence of the trimethylsilyl- and trimethyl- -germyl- substituents on the strengths of some carboxylic acids indicates that the inductive electron-releasing effect is slightly greater, and steric effects consider- -ably less, in the latter group. The alkaline cleavage of numerous tetra-organo- -silanes, -germanes, and -stannanes has been examined. The absolute and relative rates vary widely with the constitution of the compounds, but the germanes are generally much less reactive than the silanes, which are rather less reactive than the stannanes. The tetraorgano-stannanes are often less reactive than might be anticipated. The results are interpreted in terms of decreasing availability of the vacant d-orbitals for transition- state stabilisation as we descend Group IVB. The trimethylaralkyl-germanes and ...

Surface modification of argon-plasma-pretreated poly(tetrafluoroethylene) (PTFE) film via UV-induced graft copolymerization with glycidyl methacrylate (GMA) was carried out first. Reactive adsorption of γ-aminopropyltriethoxysilane (APS) onto the GMA graft-copolymerized PTFE (GMA-g-PTFE) film surface was performed by the simple immersion of the film in the APS solution. The adsorption process was studied as a function of the APS concentration, the immersion time of the graft-modified PTFE film in the APS solution, and the washing protocol. The chemical composition and morphology of the silane-modified surfaces were characterized by X-ray photoelectron spectroscopy and atomic force microscopy, respectively. The performance of the silane-modified PTFE surface in adhesion promotion was investigated. The T-peel adhesion strength of the evaporated Cu on the PTFE film with the reactively adsorbed organosilane increased significantly to about 12.15 N/cm. This adhesion strength was more than twice that ...

http://www.kemi.se/lagar_eng/pdf/app5_8.pdf. Soil dissipation. The Meeting reviewed the final report of a 3-year soil dissipation study (4 applications per year) for which an interim report was reviewed by the 1989 JMPR. It confirms the 1989 observations that over 92% of the radioactivity is confined to the top 8 cm of soil over the test period, and that the predominant residues in this segment are flusilazole and its silanol metabolite IN-F7321. The author cites statistical evaluation of the data to support the view that residues will reach a steady level at 57% of yearly application levels after repeated application levels under worst-case conditions. The report cites the steady-state conclusion, the strong adsorption to the top layers of soil, the lack of residues exceeding 0.01 mg/kg in the 24-36 cm soil depths and the weak leaching potential indicated in other studies as evidence that residues in ground water were unlikely. While the data indicate that over 92% of the radioactivity remains ...

Sol-gel entrapped lipases gained an increasing attention in the last years, as biocatalysts for several practical applications. In this study, lipases from Candida antarctica B (C-Lecta) has been immobilized by sol-gel entrapment using binary and ternary silane precursor systems containing vinyl-trimethoxysilane. The presence of vinyl functional groups in the sol-gel matrix could be important for specific applications that need further functionalization of the sol-gel matrix. The obtained enzymatic preparates were used as biocatalysts for kinetic resolution of racemic 2-hexanol and 2-octanol, by acylation with vinyl acetate in n-hexane medium. The immobilization resulted in high activity and enantioselectivity values. ...

Aliphatic, fluorinated aliphatic or substituted aromatic hydrocarbon substituents are the hydrophobic entities which enable silanes to induce surface hydrophobicity. The organic substitution of the silane must be non-polar. The hydrophobic effect of the organic substitution can be related to the free energy of transfer of hydrocarbon molecules from an aqueous phase to a homogeneous hydrocarbon phase. A successful hydrophobic coating must eliminate or mitigate hydrogen bonding and shield polar surfaces from interaction with water by creating a non-polar interphase. Although silane and silicone derived coatings are in general the most hydrophobic, they maintain a high degree of permeability to water vapor. This allows coatings to breathe and reduce deterioration at the coating interface associated with entrapped water. Since ions are not transported through non-polar silane and silicone coatings, they offer protection to composite structures ranging from pigmented coatings to rebar reinforced ...

Catalytic hydrosilylation of C=C bonds in alkenes in the presence of Ru(II)-phosphine complexes takes place only for alkoxy-substituted silanes in the absence of solvent and in the presence of small amounts of O-2. The activation effect of trace O-2, noted previously for rhodium and other transition metal phosphine complex catalysts for several catalytic processes, has been little studied to date. In this work, oxygen is considered to cause removal of phosphine as its oxide, formation of intermediate dioxygen complexes (followed by oxygenation of Ru-Si= to an Ru-O-Si= moiety with elimination of disiloxane) and possible formation of Ru(IV) species. The studies include the characterization of isolated intermediates (well defined complexes or their mixtures) from an RuCl2(PPh(3))(3)-HSi(OC2H5)(3) system and general mechanisms for the hydrosilylation of alkenes in the presence of Ru(II) precursors are discussed.. ...

Tris(trimethylsilyl)silane, TTMSSTris(trimethylsilyl)silane, TTMSS
Tributyltin hydride is the reagent of the choice for the reduction of functional groups after a radical mechanism. But organotin compounds are toxic and can sometimes only be separated laboriously from nonpolar reaction products. It was necessary to find new reagents which made the adaption of these radical methods possible in (pharmaceutical) production, without having fear of toxic impurities.. Silanes are often an alternative. But the Si-H - bond in silanes is relatively strong compared to the appropriate bond in tributyltin hydride. The discoveries gained from the 80s, that replacement of alkyl by silyl groups weakens the Si-H bond at the central silicon atom, were very important for the discovery of tris(trimethylsilyl)silane as reducing agent.

A uniaxial natural fabric of Hildegardia populifolia was treated with 5% sodium hydroxide solution for 1 h, and the resulting changes were analyzed by polarized and scanning electron microscopic techniques. The untreated and treated H. populifolia fabric was reinforced in epoxy and toughened with 10% polycarbonate. The variation of the flexural strength and flexural modulus with different fabric contents and fiber orienrations was studied. The effect of sodium hydroxide and a silane coupling agent on the flexural properties of the composite was also studied. It was observed that the flexural properties increased on alkali treatment and when the coupling agent was used. The morphology of the cryogenically fractured surfaces indicated good bonding between the matrix and the reinforcement when a coupling agent was used. © 2006 Wiley Periodicals, Inc.

Biopolymers are easily denatured by heating, a change in pH or chemical substances when they are immobilized on a substrate. To prevent denaturation of biopolymers, we developed a method to trap a polynucleotide on a substrate by hydrogen bonding using silica particles with surfaces modified by aminoalkyl chains ([A-AM silane]/SiO2). [A-AM silane]/SiO2 was synthesized by silane coupling reaction of N-2-(aminoethyl)-3-aminopropyltrimethoxysilane (A-AM silane) with SiO2 particles with a diameter of 5 μm at 100 °C for 20 min. The surface chemical structure of [A-AM silane]/SiO2 was characterized by Fourier transform infrared spectroscopy and molecular orbital calculations. The surface of the silica particles was modified with A-AM silane and primary amine groups were formed. [A-AM silane]/SiO2 was trapped with single-stranded nucleic acids [(Poly-X; X = A (adenine), G (guanine) and C (cytosine)] in PBS solution at 37 °C for 1 h. The single-stranded nucleic acids were trapped on the surface of the [A-AM

The design of novel protein-nanoparticle hybrid systems has applications in many fields of science ranging from biomedicine, catalysis, water treatment, etc. The main barrier in devising such tool is lack of adequate information or poor understanding of protein-ligand chemistry. Here, we establish a new strategy based on computational modeling for protein and precursor linkers that can decorate the nanoparticles. Moringa oleifera (MO2.1) seed protein that has coagulation and antimicrobial properties was used. Superparamagnetic nanoparticles (SPION) with precursor ligands were used for the protein-ligand interaction studies. The molecular docking studies reveal that there are two binding sites, one is located at the core binding site; tetraethoxysilane (TEOS) or 3-aminopropyl trimethoxysilane (APTES) binds to this site while the other one is located at the side chain residues where trisodium citrate (TSC) or Si-60 binds to this site. The protein-ligand distance profile analysis explains the ...

Silane coupling agents are commonly employed to link an organic polymer to an inorganic substrate. One of the widely utilized coupling agents is 3-aminopropyltriethoxy silane (APTES). In this study, the authors investigated the ability of APTES to retain thermo-responsive poly(N-isopropylacrylamide) (pNIPAAm) on hydroxylated surfaces such as glass. For comparison purposes, the authors also evaluated the retention behaviors of (1) polystyrene, which likely has weaker van der Waals interactions and acid-base interactions (contributed by hydrogen-bonding) with APTES, on APTES as well as (2) pNIPAAm on two other silane coupling agents, which have similar structures to APTES, but exhibit less interaction with pNIPAAm. Under our processing conditions, the stronger interactions, particularly hydrogen bonding, between pNIPAAm and APTES were found to contribute substantially to the retention of pNIPAAm on the APTES modified surface, especially on the cured APTES layer when the interpenetration was ...

Fabrication of biosensors and microarrays, and more generally of an inorganic device coupled to a biomolecule, has its main issue in bioconjugation, i.e. the immobilization of a working biological probe onto a solid surface. Bioconjugation represents a current challenge crossing both material sciences and biomedical applications [1-3]. Lots of chemical protocols have been reported in the literature in order to passivate and functionalize surfaces: the immobilization of biological species should not prevent their functions, and thus should also ensure their correct organization and orientation. The standard example in this field is gold functionalization by self-assembled monolayer, which gives an appropriate distance from the support surface and a strong binding to biomolecules. In the case of semiconductors and their related materials (oxides, nitrides and their porous formulae), it is not so straightforward to find a common route of functionalization: in particular, on silicon and silicon ...

Alumina platelet reinforced epoxy matrix composites with an architecture resembling to natural nacre were fabricated by a hybrid conventional method called Hot-press Assisted Slip Casting process (HASC). Correlation between processing parameters, platelet content, platelet orientation and mechanical property enhancement of the fabricated composites was examined. In order to investigate the effect of interfacial compatibility and bonding on the mechanical properties of the fabricated inorganic-organic composites, platelet surfaces were modified with both epoxy- and amino-functional silanes. As received and functionalized platelet surfaces were studied by X-Ray Photoelectron Spectroscopy (XPS) to confirm the success of surface modification. Fabricated bio-inspired bulk lamellar composite materials were characterized in terms of their microstructural architecture and mechanical properties. The results obtained indicated that HASC processed composites exhibit enhanced flexural strength, stiffness ...

In ceramic injection molding, since the particles are very fine, the powders are usually agglomerated. The agglomerates are broken up during the process of high shear mixing, but to retain the deagglomerated state, the use of processing aid is also necessary. Coupling agents, also part of the processing aid, is often used to improve the bonding of polymer to the ceramics. Thus,it is possible to imagine the complex nature of the binder systems that are used for CIM. Given below are examples of some of the commonly used materials in the binder systems: Polypropylene, polyethylene, polyvinyl chloride, paraffin wax, microcrystalline wax, polyethylene glycol, cellulose, polycarhsilane, several alcoxides, agar, vegetable oil, stearic acid, stearates, olates, silanes, titanates, etc. E. water being evaporated).

Epoxidized palm oil (EPO) based polyols were produced from three different molar ratios of EPO and glycerol (1:1.0, 1:1.5, 1:2.0) via hydroxylation reaction. The reduction of oxirane content from 2.9 to 0.04%, the increase in hydroxyl value to 509.6 mgKOH/g and high viscosity of synthesized polyols indicates the opening of epoxy ring and also showed the grafting process had been occurred. Based on FTIR and NMR spectrum, hydroxyl group has been chemically grafted onto the opened epoxy ring of EPO. Polyol-1.5 synthesized from 1 mol of EPO react with 1.5 mol of glycerol was chosen in formulating polyol-silane resin due to its optimum properties and characteristics compared with others. The polyol-1.5 was mixed with different types of silane and hardener to formulate polyol-silane resin. Each silanes was varied with three different weight percentages (10, 30 and 50 wt %).

2,3-Di-O-benzyl-4,6-O-benzylidene-thiohexopyranosides, on activation with 1-benzenesulfinyl piperidine and triflic anhydride, react with allyl silanes and stannanes, and with silyl enolethers to give C-glycosides. In the mannose series the beta-isomers are formed selectively whereas the glucose series provides the alpha-anomers. This selectivity pattern parallels that of O-glycoside formation and eliminates the need to consider donor-acceptor hydrogen bonding in the formation of the O-glycosides.

This study presents a simple approach to perform selective mass transport through freestanding porous silicon (pSi) membranes. pSi membranes were fabricated by the electrochemical etching of silicon to produce membranes with controlled structure and pore sizes close to molecular dimensions (approximately 12 nm in diameter). While these membranes are capable of size-exclusion based separations, chemically specific filtration remains a great challenge especially in the biomedical field. Herein, we investigate the transport properties of chemically functionalized pSi membranes. The membranes were functionalized using silanes (heptadecafluoro-1,1,2,2-tetrahydrodecyl)dimethylchlorosilane (PFDS) and N-(triethoxysilylpropyl)-o-polyethylene oxide urethane (PEGS) to give membranes hydrophobic (PFDS) and hydrophilic (PEGS) properties. The transport of probe dyes tris(2,2-bipyridyl)dichlororuthenium(ii) hexahydrate (Rubpy) and Rose Bengal (RB) through these functionalized membranes was examined to ...

A simple polyol-free synthesis route to Gd2O3 nanoparticles for MRI applications: an experimental and theoretical studyA simple polyol-free synthesis route to Gd2O3 nanoparticles for MRI applications: an experimental and theoretical study
This thesis work focuses on the design and production of nanoparticle based contrast agents for signal enhancement in magnetic resonance imaging (MRI). Three different synthesis routes are explored, primarily to produce crystalline gadolinium oxide (Gd2O3) nanoparticles, and surface modification is done to obtain stable, dispersible, biocompatible probes inducing high proton relaxivities.. In Paper I and II we utilized the polyol synthesis method and nanoparticle purification was performed with dialysis. Active surface functionalization was achieved by an innermost layer of 3-mercaptopropyl trimetoxy silanes (MPTS) and an outer layer of bifunctional PEG. Surface capping was shown to greatly affect the water proton relaxation to a degree which is strongly dependent on the purification time. PEGylation also induced stabilizing effects and the ability to provide the nanoparticles with luminescent properties was proven by linking the fluorescent dye Rhodamine to the bifunctional PEG.. In Paper III ...

Patent US4808511 - Vapor phase photoresist silylation process - Google PatentsPatent US4808511 - Vapor phase photoresist silylation process - Google Patents
A process for improved vapor phase silylation of photoresist is disclosed. The process uses silylation materials which either produce a strong base such as dimethylamine upon reaction with a resist film or which contain an improved chemical leaving group such as acetate. The process is effective at temperatures of 135 C. and below. Preferred silylation materials are N,N-dimethylaminotrimethylsilane and trimethylsilylacetate.

Barium siloxides and catalysed formation of Si-O-Si motifs - Université de Rennes 1Barium siloxides and catalysed formation of Si-O-Si motifs - Université de Rennes 1
The first unsupported barium siloxide, the homoleptic dimer [Ba {μ -OSi(SiMe ) } {OSi(SiMe ) }], is presented, and its structural features are discussed in the light of DFT computations. This complex, together with the related [Ba{μ -OSi(SiMe ) }{N(SiMe ) }] and their parent [Ba{N(SiMe ) } ] , mediates the formation of asymmetric siloxanes R Si-O-SiR through the first case of main group metal-mediated dehydrocoupling of silanols and hydrosilanes. Early kinetic analysis highlights an unusual catalytic manifold.

An improved process for the preparation of thermoplastic vulcanizates from butyl rubbers by hydrosilylation crosslinking of acrylic or alkacrylic functionalized copolymers of isobutylene and paramethylstyrene is disclosed. The functionalization results in lower compression and tension set than when using conventional butyl rubbers. Other physical properties of the thermoplastic vulcanizate are improved consistent with more efficient crosslinking of the functionalized copolymer.

The rich surface chemistry of mesoporous metal oxides is an important reason why they are widely used in applications such as catalysis, biomolecular separation, etc. At times the surface is modified or functionalized with organic species for stability or for a particular application. In this work, nanocast metal oxides (TiO2, ZrO2 and SnO2) and SiO2 were modified with amino-containing molecules using four different approaches, namely (a) covalent bonding of 3-aminopropyltriethoxysilane (APTES), (b) adsorption of 2-aminoethyl dihydrogen phosphate (AEDP), (c) surface polymerization of aziridine and (d) adsorption of poly(ethylenimine) (PEI) through electrostatic interactions. Afterwards, the hydrolytic stability of each functionalization was investigated at pH 2 and 10 by zeta potential measurements. The modifications were successful except for the AEDP approach which was unable to produce efficient amino-modification on any of the metal oxides used. The APTES, aziridine and PEI ...
