Chemical investigation on the ethanol extract from the whole plants of Delphinium chrysotrichum resulted in the isolation of two new diterpene alkaloids named delphatisine A （1） and delphatisine B （2）, respectively. The structures of the new compounds were deduced on the basis of their spectral data （IR, HREIMS, EIMS, 1 D, 2D-NMR）. This is the first report on the isolation of diterpenoid alkaloids from the D. chrysotrichum.

A theoretical scheme of quantum secure direct communication using teleportation is proposed. In the scheme, the sender needs to prepare a class of three-particle W states to use as quantum channel. The two communicators may communicate after they test the security of the quantum channel. The security of the protocol is ensured by quantum entanglement and quantum no-cloning theorem. The receiver can obtain the secret message determinately if the quantum channel is secure.

An improvement （Y-protocol） [Commun. Theor. Phys. 49 （2008） 103] on the quantum secure direct communication with W state （C-protocol） [Chin. Phys. Lett. 23 （2006） 290] is proposed by Yuan et al. The quantum bit error rate induced by eavesdropper is 4.17% in C-protocol and 6.25% in Y-protocoL In this paper, another improvement on C-protocol is given. The quantum bit error rate of the eavesdropping will increase to 8.75%, which is 1.1 times larger than that in C-protocol and 0.4 times larger than that in Y-protocol.

To search for pharmacologically and structurally interesting substances from traditional Chinese medicines, we Investigated the chemical compounds of Aconitum spicatum Stapf. Two new nordlterpenold alkaloids, namely spicatlne A （compound 1） and splcatine B （compound 2）, as well as 11 known norditerpenoid alkaloids were Isolated from the CHCIs portion of the 90% ethanol extract of the roots of A. spicatum. The structures of the alkaloids were characterized on the basis of their spectral data. One of the Isolated compounds showed significant cytotoxic activities （IC50 values 〈 200μmol/l.） against the HL-60 cell line.

The effects of gate oxide traps on gate leakage current and device performance of metal–oxide–nitride–oxide–silicon(MONOS)-structured NAND flash memory are investigated through Sentaurus TCAD. The trap-assisted tunneling(TAT)model is implemented to simulate the leakage current of MONOS-structured memory cell. In this study, trap position, trap density, and trap energy are systematically analyzed for ascertaining their influences on gate leakage current, program/erase speed, and data retention properties. The results show that the traps in blocking layer significantly enhance the gate leakage current and also facilitates the cell program/erase. Trap density ~10^(18) cm^(-3) and trap energy ~ 1 eV in blocking layer can considerably improve cell program/erase speed without deteriorating data retention. The result conduces to understanding the role of gate oxide traps in cell degradation of MONOS-structured NAND flash memory.
