银漂色位移染料性能的研究

本文对几种银漂染料的色位移和复色性能与其分子结构的关系进行了研究。结果显示,以N-苯甲酰化J-酸、G-酸、变色酸为偶合组分的染料具有较好的位移和复色性能,而以R-酸、N-酰化H-酸等为偶合组分的银漂染料性能较差。位移染料M-16、C-20的初步涂布应用表明,其样片感光度分别提高了3.8和6.3倍。     

Crystal Structure and Electrochemical Behavior of Copper Complex with 6-Hydroxymethyl-substituted Tris（2-pyridylmethyl） Amine, [CuCl（C19H20N4O）]ClO4

1 INTRODUCTION The copper plays an important role in metallo-proteins involved in significant electron transfer andoxygenation reactions[1]. Various model complexesfor such enzymes have been synthesized and the re-activity to oxygen been investigated…

The Elastic Continuum Limit of the Tight Binding Model

The authors consider the simplest quantum mechanics model of solids,the tight binding model,and prove that in the continuum limit,the energy of tight binding model converges to that of the continuum elasticity model obtained using Cauchy-Born rule.The technique in this paper is based mainly on spectral perturbation theory for large matrices.
