SiO2-supported Ni-Mo bimetallic phosphides were prepared by temperature-programmed reduction(TPR) method from the phosphate precursors calcined at different tem
Carbon deposition is a commonplace phenomenon occurring in the catalytic reaction process,in particular in the system of direct dehydrogenation of ethylbenzene,
We designed and synthesized a triarm star-shaped rod-rod block copolymer(BCP),(poly{2,5-bis[(4-methoxyphenyl)-oxycarbonyl]styrene}-block-poly(γ-benzyl-L-glutam
Four thiophene derivatives were prepared by replacing the 3,4 positions of thiophene by―OCH3, ―CH3―COOCH3 and ―CN, respectively. The polycondensations via d
