High purity polysaccharide of pachyman was isolated from the powder of Poria cocos sclerotium with an yield of 77.8%. The intrinsic viscosity of polysaccharide
The trinuclear complex bis(18-crown-6)thallium tetracyanoplatinate [Tl2(18-crown- 6)2Pt(CN)4]·2H2O was prepared and its structure was determined by X-ray diffr
An N-hydroxyl peptide unit of H-L-Pro-L-Ala-L-Ala-β-(BnO)Ala-OMe was synthesized by stepwise chain building method in solution. Then, based on nitrilotriacetic
The behavior of a thin curved hyperelastic film bonded to a fixed substrate is described by an energy composed of a nonlinearly hyperelastic energy term and a d
We derive equations and study nonlinear dynamics of cascade two-photon laser, in which the electromagnetic field in the cavity is driven by coherently prepared
