The optical absorption of 4H-,6H-and 15R-SiC single crystals has been measured at room temperature. The band gaps were calculated,and the reasons for band gap s
The title compound E-4,4'-bis(N,N-di-n-butylamino)stilbene (abbreviated to BDBAS) was synthesized by a simple and effective solvent-free wittig reaction wit
Density functional theory periodic slab calculations were carried out for CO adsorption on a series of Mo modified Pt(111) surfaces to provide an insight into t
A novel ternary borate, sodium strontium pentaborate, NaSrB5O9, has been prepared by solid-state reaction below 800 ℃. The single-crystal X-ray structural anal
