Micro porous carbons are used for the sorption/separation of light gases, where as the carbon with broad pore size is applied for removal of large organic molecules. In this work activated carbon was prepared from natural material pine wood. Pine wood monoliths were carbonized in inert nitrogen atmosphere for different intervals of times. To enhance the surface area and to develop interconnecti...

Based on the basic mechanism and bionics principle that texture affects dynamic pressure effect of lubricating medium, a V-shaped converges along sliding direction is designed. Through numerical simulation, optimal geometric parameters distribution textures are obtained. A textured surface with various features prepared using nanosecond ultraviolet laser bearing steel as substrate. Tribological...
