) porous network structure with high specific surface area, which is conducive to the exposure of more active sites. It is interesting to note that the catalytic activity of oxygen reduction strongly depends on the proportion of graphic N rather than the total N content. Key words: oxygen reduction reaction; nitrogen-doped carbon; porous structure; red-blood-cell-like morphology Cite this article......
are ideal heat dissipation materials widely applied in field of aerospace, such as porous wick for loop heat pipe. Due to the structure characteristics and harmless to human body, copper porous..., porosity, pore structure and pore size distribution are the guarantee of excellent heat transfer and permeability for porous materials. The microstructure of materials is mainly influenced......
