Polymerization of 4-vinylpyridine was carried out with the lanthanide coordination catalyst. The influence of the component in catalytic system and solvents had
A New Triterpenoid from “Gualou-xiebai-baijiu-tang” Consisting of Fructus trichosanthis and Bulbus a
A new triterpenoid saponin was isolated by bioactivity-guided isolation from "Gualou-xiebai-baijiu-tang" consisting ofFructus trichosanthisi and Bulbus allii ma
(-)-Menthol reacts with phosphorus trichloride to afford menthyl phosphorodichloridite 2,which further reacts with racemic 1, 1'-binaphthalene-2, 2'-diol to giv
The dynamics of a relativistic electron submitted to an intense, plane wave, linearly polarized laser field is reviewed. Based on the dynamics, the temperature
The air-solution equilibrium tension ye and dynamic surface tension ye, of nonionic surfactant alkyl polyglucoside have been studied. ye was measured by the Wil
Electrochemical Behavior and Its Electrocatalytic Activity of A P-Mo Heteropolyanion Modified ITO El
A new method for the preparation of an organic-inorganic composite fihm of the heteropolyanion has been developed by modifying P(Mo2O7)6-7 to the indium tin oxi
We study high energy proton-proton elastic scattering in the framework of Pomeron exchange model. The cross section of the process are calculated without any fr
We study pion-proton Orp) Drell-Yan (DY) dilepton production in the target rest frame with color dipole model. The prediction for πp DY cross section at the en
Meson Cloud Effect on △(1232) Resonance Transition Properties with a Relativistic Quark Model Approa
Based on a relativistic quark model approach, the transition properties of the first nucleon resonance △(1232), and the coupling constants gπNN, g△πN are in
