Hypocrellin A(HA), a photosensitive perylenequinone compound of Hypocrella bambusae , inhibited the proliferation of several tumor cell lines. Human cervical ca
A two-step Taylor-Galerkin fractional-step finite element method, which is of second order accuracy in space and time, was proposed for the three-dimensional fr
A new catalytic process for the synthesis of aldehyde from alcohol by oxidation with H2O2 with high selectivity was studied. In this system, heteropolymolybdate
In the present paper, we calculate the Gaussian correction to the critical value Jc⊥ caused by quantum spin fluctuation in a two-dimensional spatially anisotro
In the present paper the Lie symmetrical non-Noether conserved quantity of the Poincaré-Chetaev equations of a generalized classical mechanics under the genera
To improve the biological anticancer activity of 20(S)-camptothecin, a novel class of 20(S)-20-O-camptothecin β-aminopropionates were designed and synthesized
Thirteen homocamptothecin derivatives were synthesized and in vitro antitumor activities were evaluated by the standard MTT method. The results showed that some
In this article, the error analysis in the quantum counting algorithm is investigated. It has been found that the random error plays as important a role as the
Iodine was found to be an efficient catalyst for the one pot synthesis of α-amino phosphonate from aldehydes, anilines and diethyl phosphite. The influences of
