BN nanotubes are coated with SnO(2) by a simple chemical reaction in solution. BN nanotubes are stirred inside a SnCl(2) solution at room temperature for 1 h. The coating is uniform with complete coverage. The coating thickness is typically 1-5 nm. The coating layer contains SnO(2) nanoparticles with sizes ranging from 1 to 5 nm.

In this work, formation of diamond coating is studied using large-scale molecular dynamics (MD) simulation. The diamond coating is studied to explore how and to what extent the temperature and pressure affects the deposition structure. To analyze the coating results, the radial distribution function and the fraction of diamond (sp bonds) is calculated. It is found that the sp fraction in the de...

A novel method, snow globe coating, is found to show significant enhancement of the short circuit current JSC (35%) when applied as a scattering back reflector for polycrystalline silicon thin-film solar cells. The coating is formed from high refractive index titania particles without containing binder and gives close to 100% reflectance for wavelengths above 400 nm. Snow globe coating is a phy...

An improved coating of gasification catalyst for carbon-graphite fibers is provided comprising a mixture of a polyvalent metal such as calcium and a monovalent metal such as lithium. The addition of lithium provides a lighter coating and a more flexible coating when applied to a coating of a carboxyl containing resin such as polyacrylic acid since it reduces the cross-link density. Furthermore,...

After coating, the resist film contains a remaining solvent concentration depending on the resist, the solvent, the resist film thickness and the resist coating technique. The softbake reduces the remaining solvent content in order to: avoid mask contamination and/or sticking to the mask, prevent popping or foaming of the resist by N2 created during exposure, improve resist adhesion to the subs...

introduction: tooth avulsion is a real dental emergency. if immediate replantation is not performed, the avulsed tooth may be lost due to inflammatory or replacement resorption. this animal study aimed to evaluate the bone response to the titanium coating of the root surface as an artificial barrier, and prevention of resorption of avulsed teeth. methods and materials: this experimental study w...

nano-films consisting of an alternating sequence of positively and negatively charged polyelectrolyteshave been prepared by means of the electrostatic layer-by-layer sequential assembly technique on mildsteels. the mild steels were pretreated electrochemically to modify the mild steel surface. the modificationof the mild steel surface resulted in increasing the adhesion of the obtained nano-fil...

B16/F10 melanoma cells, in a medium containing fibrinogen, form a coating of fibrin(ogen) on their surfaces. This coating is cross-linked in a manner characteristic of catalysis by cellular transglutaminase. The fibrin(ogen) coating on the surface of these tumor cells provides protection against the lytic effect of autologous lymphokine-activated killer cells.

There are some arguments between the use of hydroxyapatite and porous coating. Some studies have shown that there is no difference between these two coatings in total hip arthroplasty (THA), while several other studies have shown that hydroxyapatite has advantages over the porous one. We have collected the studies in Pubmed, MEDLINE, EMBASE, and the Cochrane library from the earliest possible y...
