As biocompatible metallic materials, titanium and its alloys have been widely used in the orthopedic field due to their superior strength, low density, ease of processing. However, further improvement biological response is still required for rapid osseointegration. Here, various Ti surface-treatment technologies were applied: hydroxyapatite blasting, sand blasting acid etching, anodic oxidatio...

steam reforming integrated with oxidation of methanol was considered with numerical simulation. the parallel micro-channels with circular cross sections were used. because when the catalytic deposited inside the rectangular micro-channels, it fills up the edges. hence, the approximation of a cylindrical channel is appropriate. effect of this changing in cross section was considered and results ...
