标题:通过双重光还原产生噻吨酮氢阴离子及其在催化光还原中的用途
摘要:阴离子是预催化剂的还原形式,是一种特殊类型的光氧化还原催化剂,与传统的铱或钌络合物不同.其中,由于快速的非辐射衰变,自由基阴离子的激发态寿命通常要短得多.在此,我们报告了噻吨酮氢阴离子(5)的发现,这是一种具有长激发态寿命的超还原光催化剂(e Ox * =-2.74 V Vs Sce,τ S = 4.1 Ns).使用5作为催化还原剂,我们开发了一系列光还原反应,包括氢化,还原脱卤,脱氧氢化和脱氧,从而证明了2E连续光致电子转移(conpet)策略的可行性和催化剂的多功能性.

摘要:The invention relates to crystalline nanometric olivine-type LiFe 1-x M x PO 4 powder with M being Co and/or Mn, and 0≦x≦1, with small particle size and narrow particle size distribution. A direct precipitation process is described, comprising the steps of: providing a water-based mixture having at a pH between 6 and 10, containing a dipolar aprotic additive, and Li (I) , Fe (II) , P (V) , and Co (II) and/or Mn (II) as precursor components; heating said water-based mixture to a temperature less than or equal to its boiling point at atmospheric pressure, thereby precipitating crystalline LiFe 1-x M x PO 4 powder. An extremely fine particle size is obtained of about 80 nm for Mn and 275 nm for Co, both with a narrow distribution.

摘要:The present invention provides a new method for extracting Homoharringtonine (HHT) by culture cells or culture plant tissues. Also, disclosed are methods of obtaining HHT from semi-synthesis and biosynthesis. The present invention disclosed that HHT combined with some botanical drugs could induce cancer cells to resemble normal cells. To add some botanical drugs combined with HHT can significantly increase anticancer effects of HHT. These drugs include Matrine (MAT), Guanzhongsu (GU), Maidongsu (MU), and Indirubin (IND). The experimental data showed that above drugs have strong synergisms effects for treating leukemia and other cancer cells and more safe.
