Scvcral isoxazolinc compounds were obtained by the 1,3-dipolar cycloaddition of benzonitrile oxide to 5-(R)-(l-menthyloxy)-2(5H)-furanone. The reaction conditio
Recent experiments revealed that the dielectric dispersion spectrum of fission yeast cells in a suspension was mainly composed of two sub-dispersions. The low-f
Two new spirostanol glycosides named agamenoside A and B, were isolated from the fcrmcnted leaves of Agave americana. Their structures were elucidated as (23S,
Copolymerization of styrene (St) with N-phenylmaleimide (NPMI) was studied with rare earth coordination catalyst Nd(naph)3-AlEt3 in toluene. Characterization of
With the low-lying energy levels, E2 transition branching ratios and absolute transition rates of the 134Ba and 108Pd, are investigated in the neutron-proton in
Friedberg, Lee and Zhao (FLZ) proposed a method for effectively evaluating the eigenenergies and eigen wavefunctions of quantum systems. In this work, we study
The heterogeneous free-radical polymerization of methyl methylacrylatc (MMA) and divinylbenzene (DVB) as cross-linker within supercritical carbon dioxide-swolle
Pyridinium ylids 4 were generated as reaction intermediates from the decarboxylation of pyridinium bctaincs 3, which were preparcd from the reactions of x-amino
Based on supersymmetric quantum mechanics theory, we introduced a supersymmetric unitary transfor mation to diagonalize the Hamiltonian of non-degenerate two-mo
