Silica film coating method for veneering resin composite. (3/3)

The preceramic polymer perhydropolysilazane (PHPS) is an attractive candidate as a coating material to prevent discoloration of veneering resin composites. At the present time, however, a practical method to apply this material is not available. The purpose of this study was to establish a low-temperature method for applying a silica film coating to a veneering resin composite. Two types of PHPS, NP and NL, were coated onto a veneering resin composite. The specimens were exposed to hydrogen peroxide vapor at 97 degrees C, and the state of the conversion process was evaluated using FT-IR. With exposure to the hydrogen peroxide vapor, a 0.5-microm-thick silica film similar to that produced by baking was formed on the surface of the NP samples in 10 min, while a 0.2-microm-thick film was formed on the NL in 15 min. The silica coating method described in this study may mitigate the discoloration of veneering resin composite.  (+info)

The thrust of this thesis is to study oral solid dosage formulation using hot melt coating method and to use pharmacokinetic modeling and simulation (PK M&S) as a tool that can help to predict pharmacokinetics of a drug in human and the probability of passing various bioequivalence criteria of the formulation based on the PK of the drug. Hot-melt coating using a new method, direct blending, was performed to create immediate and sustained release formulations (IR and SR). This new method was introduced to offer another choice to produce IR and SR drug delivery formulations using single and double coating layer of waxes onto sugar beads and/or drug loaded pellets. Twelve waxes were applied to coat sugar cores. The harder the wax the slower the drug was released from single coated beads. The wax coating can be deposited up to 28% of the weight of the core bead with 58% drug loading efficiency in the coating The cores were coated with single or double wax layers containing acetaminophen.

A method for coating or impregnating a substrate such as a textile fabric with a treatment material such as a water or stain resistant coating comprises the steps of (a) combining a substrate and an inert transfer vehicle (e.g., a sheet material) in a pressure vessel, the inert transfer vehicle carrying the treatment material; (b) pressurizing the vessel with a carbon dioxide medium; and then (c) agitating the substrate and the inert transfer vehicle together in the pressure vessel with the substrate and the inert transfer vehicle at least periodically immersed in the carbon dioxide medium so that the treatment material is transferred from the inert transfer vehicle to the substrate.
A method for coating a sealant (39) on a separator (40) for a fuel cell. The separator has a sealing groove (118) formed therein, and widths of the sealing groove at a coating-start portion (39a) and a coating-end portion (39b) of the sealant are made greater than widths of remaining portions of the sealing groove. The sealant coating-start portion and the coating-end portion are made to intersect at a place where the width of the sealing groove is large. Adhesion between the coating-start portion and the coating-end portion is improved, and also, degrees of freedom of a sealant coated position increase, and sealability of a cell for a fuel cell is improved.

The utilization of Electroless Nickel-Phosphorus (EN) coatings has witnessed a staggering increase during the last two decades. Many outstanding characteristics of the EN coating method have generated a lot of interest in various industries including oil and gas, electronic, chemical, automotive, aerospace, and mining. Some of the highlighted characteristics of EN coatings are superior corrosion and wear resistance especially in environments containing H2S and CO2, superior mechanical properties, uniform coating thickness, excellent surface finish properties, superb adhesion characteristics, and wide range of thickness. The EN coating process is based on a redox reaction in which a reducing agent is oxidized and Ni+2 ions are reduced on the surface of the substrate materials. Once the first layer of Ni is deposited, it acts as a catalyst for the process. Consequently, a linear relationship between coating thickness and time usually occurs. If the reducing agent is sodium hypophosphite, the ...

Excessive use of antibiotics in human and animal husbandry is known to promote the selection and development of bacterial strains showing resistance to antibiotics.. Pathogens cause millions of infections and worldwide economic damage every year. The current ("gold" standard) detection methods of bacterial, viral or suspect cells in samples are not optimal. The current method is time consuming. Rapid pathogenic tests are not sensitive enough to detect very low numbers of cells in fluids, without an initial separation and concentration procedure. CBMR is currently developing a real time sensor system, this is a peptide-based coating method that is able to bind particles to an increased extent. It works like a magnet that attracts iron particles. The sensor selectively extracts particles, thereby rendering a high concentrate with specifically sought-after properties.. Possible other applications for AMPs are to eradicate pathogens from body surfaces of colonized patients, or to coat medical ...
A new high-temperature soft soldering system has been developed by the Bureau of Mines for use on copper, copper alloys, and low-carbon steel; the method is applicable to automobile radiators and home appliances.

Porous silica films with various porosities were prepared via a sol-gel method using a nonionic amphiphilic triblock copolymer F127 as the structure-directing agent. Doppler broadening of positron annihilation radiation (DBAR) spectra were collected for the prepared films using a variable energy slow positron beam. Different linear relationships between positron annihilation line shape parameters S and W are found for the as-deposited films and calcined ones, indicative of the decomposition of the copolymer porogen in the as-deposited films upon calcination. This also reveals the variation of positron annihilation sites as a function of F127 loading or porosity. Strong correlations between positronium 3γ annihilation fraction, S parameter and porosity of the mesoporous silica films with isolated pores are obtained, which may provide a complementary method to determine closed porosities of mesoporous silica films by DBAR. ...
0072] At least the base material layer 1, the adhesive layer 2, the metal layer 3 and the sealant layer 4 are laminated in this order to obtain a laminate. Specifically, a solvent containing the resin composition is first applied to at least one of the base material layer 1 and the metal layer 3. For the application of the solvent, a coating method such as an extrusion method, a gravure coating method or a roll coating method can be employed. Next, the solvent is evaporated. Next, the base material layer 1 and the metal layer 3 may be bonded and laminated to each other. Lamination of the base material layer 1 and the metal layer 3 with the resin composition interposed therebetween can be performed by, for example, a dry lamination method. Next, the resin composition situated between the base material layer 1 and the metal layer 3 is irradiated with an ionizing radiation or heated to cure the resin composition, thereby forming the adhesive layer 2. For example, when the base material layer 1 is ...

The coating of thin films is applied in numerous fields and many methods are employed for the deposition of these films. Some coating techniques may deposit films at high speed; for example, ordinary printing paper is coated with micrometre-thick layers of clay at a speed of tens of meters per second. However, to coat nanometre thin films at high speed, vacuum techniques are typically required, which increases the complexity of the process. Here, we report a simple wet chemical method for the high-speed coating of films with thicknesses at the nanometre level. This soap-film coating technique is based on forcing a substrate through a soap film that contains nanomaterials. Molecules and nanomaterials can be deposited at a thickness ranging from less than a monolayer to several layers at speeds up to meters per second. We believe that the soap-film coating method is potentially important for industrial-scale nanotechnology.. ...

0064] In an embodiment of the system and corresponding method of the disclosed subject matter, the translation of the expandable member with respect to the positioning device is a ratio of 1:1. The expandable member can be inflated to or above nominal pressure to minimize any compressive force resulting from the pressurized fluid impacting the expandable member. By utilizing a positioning device that does not contact the surface of the expandable member, the risk of interfering or disturbing the coating fluid applied by the outlet can be minimized. Additionally, the absence of contact between the expandable member and the positioning device is advantageous in reducing the forces required to establish the relative movement between the expandable member and the outlet of the applicator. As previously noted, the coating method and system of the disclosed subject matter can be performed on a fully assembled medical device, e.g. balloon catheters, wherein the force required to rotate or otherwise ...
ZnO thin film of 80 nm thickness was deposited by the sol-gel spin coating method on SiO2/Si substrate and subsequently post-annealed at 500°C with a flow of oxygen for 60 min. Crystallographic structure of the sample was characterized by X-ray diffraction (XRD) method while a field emission scanning electron microscope (FESEM) was used to investigate the surface physical morphology and chemical composition. The sensitivity of the sample was tested to acetic acid vapor with different concentrations (20 ppm, 40 ppm, and 80 ppm) in the temperature range of 200-400 °C. The results showed that the ZnO thin film can be introduced as an acetic acid vapor sensor with a good reliability and detection limit of 20 ppm at the operating temperature of 320°C.

Cadmium chalcogenides with appropriate band gap energy have been attracting a great deal of attention because of their potential applications in optoelectronic devices. In this work CdS thin films were deposited on p - type silicon substrates by sol - gel spin coating method at different substrate temperatures. The CdS deposited wafers were characterized by X‐ray diffraction method (XRD), Scanning Electron Microscopy (SEM), Photoluminescence spectroscopy (PL), Raman spectroscopy and Fourier Transform Infra - Red spectroscopy (FTIR). XRD analysis showed that the films have crystallites with classical hexagonal structure along (0 0 2) plane. The grain size was found to be in the range of 111.79 nm to 167.66 nm varying with the annealing temperature. The SEM micrograph of annealed CdS thin film showed uniform granular structures with very well defined grain boundaries all over the surface. The Raman spectra of the CdS films presented a well-resolved line at 300 cm−1 (1LO) and at 611 cm-1 (2LO). PL

Highly porous 45S5 bioactive glass-based scaffolds were fabricated by the foam replica technique and coated with collagen by a novel method. After an initial cleaning step of the bioactive glass surface to expose reactive –OH groups, samples were surface functionalized by (3-aminopropyl)triethoxysilane (APTS). Functionalized scaffolds were immersed in a collagen solution, left for gelling at 37 °C, and dried at room temperature. The collagen coating was further stabilized by crosslinking with 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide (EDC) and N-hydroxysuccinimide (NHS). Applying this coating method, a layer thickness of a few micrometers was obtained without affecting the overall scaffold macroporosity. In addition, values of compressive strength were enhanced by a factor of five, increasing from 0.04 ± 0.02 MPa for uncoated scaffolds to 0.18 ± 0.03 MPa for crosslinked collagen-coated scaffolds. The composite material developed in this study exhibited positive cell (MG-63)
Hematite (alpha-Fe2O3) is a promising semiconductor as photoanode in solar hydrogen production from photoelectrolysis of water due to its appropriate band gap, low cost and high electrochemical stability in aqueous caustic electrolytes. Operation of such photoanode in a biased photoelectrochemical cell constitutes an anodization with consequent redox reactions at the electrode surface. alpha-Fe2O3 thin film photoanodes were prepared by simple and inexpensive dip coating method on fluorine doped tin oxide (FTO) glass substrate, annealed in air at 500 degrees C for 2 h, then electrochemically oxidized (anodized) in 1 M KOH at 500 mV for 1 min in dark and light conditions. Changes in structural properties and morphology of alpha-Fe2O3 nanoparticles films were investigated by XRD, Raman spectroscopy and a high resolution FESEM. The average grain size was observed to increase from similar to 57 nm for pristine samples to 73 and 77 nm for anodized samples in dark and light respectively. Broadening and ...
Recently a perovskite-based material with exceptional photovoltaic properties has been discovered: CH3NH3PbI3. Energy conversion efficiencies beyond 19% have been reported for solution-processed thin film solar cells based on this perovskite.

In this paper we have successfully demonstrated a new micromachined fuel processing system including vaporizer, catalytic combustor and methanol steam reformer. This fuel processing system utilizes the thermal energy generated from the catalytic hydrogen combustion to heat up the entire system. For the first time, we have used carbon nanotubes as a supporting structure of Pt catalyst for combustion. The catalytic combustor could supply the energy to heat the reformer and maintain its working temperature. We have also developed a new coating method of reforming catalyst (Cu/ZnO/Al2 O3 ) and observed that adequate amount of hydrogen can be generated for PEMFC. We have successfully reported the feasibility of the proposed fuel processing system in each assembled component.. Copyright © 2006 by ASME ...
We introduce a method that combines two-photon polymerization (TPP) and surface functionalization to enable the indirect optical manipulation of live cells. TPP-made 3D microstructures were coated specifically with a multilayer of the protein streptavidin and non-specifically with IgG antibody using polyethylene glycol diamine as a linker molecule. Protein density on their surfaces was quantified for various coating methods. The streptavidin-coated structures were shown to attach to biotinated cells reproducibly. We performed basic indirect optical micromanipulation tasks with attached structure-cell couples using complex structures and a multi-focus optical trap. The use of such extended manipulators for indirect optical trapping ensures to keep a safe distance between the trapping beams and the sensitive cell and enables their 6 degrees of freedom actuation.. © 2015 Optical Society of America.

Low-density polyethylene (LDPE) nanocomposites containing metal oxide nanoparticles are considered as promising candidates for insulating materials in future high-voltage direct-current (HVDC) cables. The significant improvement in dielectric properties compared with unfilled polymer is attributed to the large and active interface between the nanoparticles and the polymer. The nanoparticles may also initiate cavitation under stress and potential accelerated aging risks due to the adsorption and inactivation of the protecting antioxidants. This study is focused on the possibilities of achieving well-balanced performances of the polyethylene nanocomposites for HVDC insulation via tailoring the particle interface in the nanocomposites.. A facile and versatile surface coating method for metal oxide particles was developed based on silane chemistry. The developed method was successfully applied to 8.5 nm Fe3O4, 25 nm ZnO and 50 nm Al2O3 particles, with the aim to develop uniform coatings that ...
The researchers targeted their fluorescent protein to the liver - an organ particularly difficult to visualize because of its high blood content. Adenovirus particles containing the gene for iRFP were injected into mice. Once the viruses and their gene cargoes infected liver cells, the infected cells expressed the gene and produced iRFP protein. The mice were then exposed to near-infrared light and it was possible to visualize the resulting emitted fluorescent light using a whole-body imaging device. Fluorescence of the liver in the infected mice was first detected the second day after infection and reached a peak at day five. (See accompanying images.) Additional experiments showed that the iRFP fluorescent protein was nontoxic.. "Our study found that iRFP was far superior to the other fluorescent proteins that reportedly help in visualizing the livers of live animals," said Grigory Filonov, Ph.D., a postdoctoral fellow in Dr. Verkhushas laboratory at Einstein, and the first author of the ...

Surface finish must be appropriate for the design objectives. If the part roughness is much greater than the coating thickness, then the coating cannot work properly. In a sliding wear application, the peaks of the roughness can shear off, exposing substrate material. In some applications, a part should not be too smooth either. In these applications a mirror finish can lead to sticking caused by suction between parts. A micro-rough finish can be advantageous to break the vacuum between parts allowing air to penetrate. BryCoat has finishing capabilities to change surface finish in many cases ...

Here, we sought to develop a cell culture surface conversion technique that would not damage living cells. An alginate thin film, formed on a glass plate by spin coating of sodium alginate solution and dipping into calcium chloride solution, was used to inhibit adhesion of cells. The film could be removed by ethylenediaminetetraacetate (EDTA) at any time during cell culture, permitting observation of cellular responses to conversion of the culture surface in real time. Additionally, we demonstrated the validity of the alginate thin film coating method and the performance of the film. The thickness of the alginate thin film was controlled by varying the rotation speed during spin coating. Moreover, the alginate thin film completely inhibited the adhesion of cultured cells to the culture surface, irrespective of the thickness of the film. When the alginate thin film was removed from the culture surface by EDTA, the cultured cells adhered to the culture surface, and their morphology changed. ...
We show that the high-energy ion irradiation of embedded metallic spherical nanoparticles (NPs) is not limited to their transformation into prolate nanorods or nanowires. Depending on their pristine size, the three following morphologies can be obtained: (i) nanorods, (ii) facettedlike, and (iii) almost spherical nanostructures. Planar silica films containing nearly monodisperse gold NPs (8â€"100 nm) were irradiated with swift heavy ions (5 GeV Pb) at room temperature for fluences up to 5Ã-1013 cm-2. The experimental results are accounted for by considering a liquid-solid transformation of the premelted NP surface driven by the in-plane stress within the ion-deformed host matrix. This work demonstrates the interest of using ion-engineering techniques to shape embedded nanostructures into nonconventional configurations ...

The optical transmittance of the film coated on the glass slide was comparable to that of the microscope glass slide. Atomic Force Microscopy (AFM) was used to characterize the surface structures; a tipless probe allowed measurement of the force of interaction with superhydrophobic surfaces. The interaction force between the AFM probe and the superhydrophobic surface was reduced greatly compared to that between the probe and the flat surface treated with fluoroalkyl silane ...

We demonstrate both theoretically and experimentally that a gold nanostrip supported by a thin dielectric (silicon dioxide) film and a gold underlay forms an efficient (Fabry-Perot) resonator for gap surface plasmons. Periodic nanostrip arrays are shown to exhibit strong and narrow resonances with nearly complete absorption and quality factors of ~15-20 in the near-infrared. Two-photon luminescence microscopy measurements reveal intensity enhancement factors of ~120 in the 400-nm-period array of 85-nm-wide gold strips atop a 23-nm-thick silica film at the resonance wavelength of ~770nm. Excellent resonant characteristics, the simplicity of tuning the resonance wavelength by adjusting the nanostrip width and/or the dielectric film thickness and the ease of fabrication with (only) one lithography step required make the considered plasmonic configuration very attractive for a wide variety of applications, ranging from surface sensing to photovoltaics.. ©2011 Optical Society of America.

VI is translated as a precursor (pVI) that is cleaved at both N- and C-termini by AVP. Whereas the role of the C-terminal fragment of pVI, pVIc, is well established as an important co-factor of AVP, the role of the N-terminal fragment, pVIn, is currently elusive. In fact, the fate of pVIn following proteolytic cleavage is completely unknown.
