New conducting thin films derived from M(dimt)2 salts (M=Ni(II), Pd(II)) by using poly counter cations

Two kinds of new M(dmit)₂ salts (M=Ni and Pd, (dmit=1,3-dithole-2-thione-4,5-dithiolate)) containing poly(4-vinyl-N-octanylpyridinium) (PVOP) as counter cations were synthesized. Semiconducting thin films derived from these salts were prepared by electrochemical deposition method. The Ni(dmit)₂ film shows an extremely smooth and uniform surface. The film-forming property of the Ni(dmit)₂ salt has been improved significantly by using PVOP as counter cation.

Molecular Dynamics Study of gases H2,D2 and T2

The classical Molecular dynamics simulation has been used to study the equation of state of gas H2,D2 and T2.It has also been investigated that the isotope mass affects on the accuracy of equation of state.Our calculated Iesults show that the classical effect is principal and the isotope mass effects on the equation of state are obvious for the much light gases.At the same time,some useful theoretical data of equation of state for these gases have been provided.It is found that the classical simulation is still effective to the quantum gas.However,the quantum mechanics simulation and the improvement of intermolecular interaction potential are necessary if more accurate computational results are expected.

CONVERGENCE OF INEXACT CONIC NEWTON METHODS

A conic Newton method is attractive because it converges to a local minimizzer rapidly from any sufficiently good initial guess. However, it may be expensive to solve the conic Newton equation at each iterate. In this paper we consider an inexact conic Newton method, which solves the couic Newton equation oldy approximately and in sonm unspecified manner. Furthermore, we show that such method is locally convergent and characterizes the order of convergence in terms of the rate of convergence of the relative residuals.     

Synthesis,characterization and in vitro cytotoxicity screening of some triarylbismuth(V) di(N‐salicylidene)amino carboxylates and the crystal structure of (2‐HOC6H4CHNCH2CO2)2Bi(C6H5)3

Four novel triarylbismuth(V) di(N‐salicylidene)amino carboxylates were synthesized. Their structures were confirmed by IR, ¹H NMR, ¹³C NMR and elemental analysis. The crystal structure of (2‐HOC₆H₄CH?NCH₂CO₂)₂BiPh₃ was determined by X‐ray diffraction. The in vitro cytotoxicity of all compounds against three human cancer cells (HL‐60, BGC‐823 and MDA‐MB‐435) at 10 µM are reported. Copyright © 2005 John Wiley & Sons, Ltd.     

Regioselective Propargylation of Aldehydes with Propargyl Bromide Mediated by Sn-In in Aqueous Media under Microwave Irradiation

Tin-indium were employed in the propargylations of various aldehydes with propargyl bromide in the presence of SnCl2 and C6H5（CH3）3NBr under microwave irradiation to afford the corresponding homopropargyl alcohols exclusively in high yields. All the reactions were completed smoothly in predominantly aqueous media in 200 seconds only.
