Single walled carbon nanotubes (SWNTs) have been shown to be highly sensitive gas sensors. However, attaching functional groups with selective sensing functions on nanotubes without destroying the intrinsic electronic property of the nanotubes is still challenging. Here, we report a new method of coating SWNTs with a thin layer of SiO2 using 3-aminopropyltriethoxyysilane as coupling layers. The...

The aim of this study was to deyelop a noyel hydroxyapatite (HA) coating method on zirconia using glass coating technique. A borosi)icate glass, the mixture of the glass ttnd HA (3e, 50, 70, and 90 mass%), and the 100% HA were coated on two kinds of zirconia discs and fired at 900-950'C. After the final coating, the surface of the sample was etched for 3 min in an acid-mixture of 3% HF and 5%HN...

In this work, modified silicone tie-paints were prepared in a simple way for securing adhesion between the epoxy anticorrosive primer and fouling release coating. Hydroxy-terminated polydimethylsiloxane (PDMS) mixture containing fillers accessory ingredient was as base component. N-(2-Aminoethyl)-3-aminopropyltrimethoxysilane (DAMO) mechanically mixed with other functional additives curing ATR-...

in this research controlled coating of magnetite (fe3o4) nanoparticles with sio2 was investigated. the fe3o4 nanoparticles were synthesized via chemical co-precipitation and then coated by silica according to stober method. effects of tetra ethyl ortho silicate (teos) concentration and ethanol to teos on the coating thickness were investigated. x-ray powder diffraction, fourier transform infrar...

A nanostructural hydroxyapatite (HA) coating was deposited to the porous Ti6Al4V acetabular cup implants using a room temperature electrophoretic deposition (EPD) process in order to achieve the improved bonding strength between the implants and cells, fast healing, good corrosion resistance and long-term stability after implantation. The micropores created in the coating will improve the bioac...
