Micro/Nano lithography of Diamond Carbon Films for use as Masters in Soft

In this study we demonstrate the use of Diamond-Like-Carbon (DLC) as a template for producing polymer micro/nano stamps and 3-D polymer structures. Intricate surface relief patterns can be formed on the DLC surface from lithographic techniques by Atomic

Decreased Platelet Adhesion and Enhanced Endothelial Cell

This study also revealed the lowest platelet adhesion on S-Ti of all the samples. In summary, without using pharmaceutical agents, significantly less platelet and greater endothelial responses on nanometer to submicron rough titanium were observed in this study compared to flat titanium and, thus, nanometer to submicron surface features on titanium should be further studied for vascular stent

Fabrication and evaluation of micromill

The micromill-grinding tool is a compound tool that has both micromilling and microgrinding abilities. Local electroplating was employed to fabricate micromill-grinding tools with CBN abrasive. The grits topography of the flank face was measured, and the graphical investigation was carried out to evaluate the distribution of the grits. It is found that the coatings were well electroplated and

(PDF) Guided assembly of nanoparticles on

Only when the intrinsic diamond is hydrogenterminated (H-diamond), a thin (10 nm) conductive layer is formed close to the diamond surface (surface conductivity) under ambient conditions [13]. While this feature attracted considerable interest and research effort in the past [14], research on electronic properties of highly resistive oxygen-terminated intrinsic diamond (O-diamond) has been
