Silicon is one of the most abundant materials on the earth crust(28%by mass,second after oxygen)and it is one of the most used materials for the mankind.
Glassy carbon(GC)is a class of nongraphitizing carbon made by firing polymeric precursors such as phenolic resin or furfuryl alcohol resin in an inert atmosphere.
A3BX4-type compounds,such as,Li3PO4,Ag3PO4,and Ag3VO4,have aroused increasing research interests in solar energy conversion and storage,environmental remediation,and solid electrolyte applications,whi
Observation of high-temperature superconductivity in compressed sulfur hydrides has generated an irresistible wave of searches for new hydrogen-containing superconductors.
A -200 K superconducting phase in dense hydrogen sulfide is an important milestone for the searching novel superconductor with high critical temperature [1,2].
