High quality GaAs/GaAsSb superlattices were grown by molecular beam epitaxy (MBE) and the Sb/As exchange action was characterized by high resolution X-ray diffraction (HRXRD).

The geometry structures and vibrational frequencies of the transition states(TS) for both abstract and exchange reaction have been obtained.

Preparation of supported Cs_2O solid base catalysts and performance of catalyzing transesterification reaction

With zinc acetate as catalyst and steric phenol Weizufen 1010 as antioxidant,the transesterification reaction conditions of NDC with EG and processing conditions for BHEN polycondensation were optimized by orthogonal experimentation.

By orthogonal (experimentation),the optimum transesterification reaction conditions of NDC with EG were obtained as follows: reaction temperature 210 ℃;mole ratio of EG/NDC 2.

In this article,reaction of transesterification of refined colza oil was studied on the basis of the studies of others,fatty acid methyl ester formate namely bio-diesel oil was obtained.
