Then a highly efficient and stereoselective hydrosilylation of terminal alkynes was developed by using the Pt(DVDS)/proazaphosphatrane complex as catalyst.

In this paper,isothermal batch static equilibrium adsorption experiments of four common saline cations(Na+、K+、Ca2+、Mg2+) were conducted in Fluvo-aquic soil from Fengqiu,Four isothemal equilibrium adsorption equations were used to simulate the equilibrium adsorption,and then the optimal isothemal equilibrium adsorption equations for each saline cation were gained.

In high speed centrifugation condition,the centrifugation temperature and NaCl ionic intension of reverse extraction solution were changed to study their effects on the separation degree and the interaction of protein and AOT,and the optimum centrifugation temperature and NaCl addition were selected.

A study on catalytic activity of solid superbase Na-Na_2CO_3/γ-Al_2O_3 in isomerization of vinyl norbornene;

The application of superbase reagent in metallation reaction;

The KF/Al_2O_3 nano superbase composite catalyst was prepared by a sol-gel method.

We investigated the effect of soils with different pH and soil extracts of nonsaline-alkali soil and saline-alkali soil on the germination and seedling growth of Leymus chinensis.
