    通过调节自由基生成策略对 RhB 选择性光催化氧化的新见解†
    摘要:
    罗丹明 B (RhB) 经常被用作模型污染物,但其光催化机制仍存在争议。在此,将Ag NPs夹在CdS QD和无定形TiO 2 (a-TiO 2 )之间,旨在构建具有高选择性氧化活性的CdS/Ag/a-TiO 2催化剂。当使用罗丹明B(RhB)作为模型有机化合物时,CdS/Ag/a-TiO 2复合材料不仅可以调节自由基的产生,而且可以将RhB向罗丹明110(Rh-110)的转化率提高至高达可见光照射80分钟时为82%。一系列自由基清除实验表明,CdS/Ag/a-TiO 2复合材料可以在不同反应阶段调节羟基自由基(·OH)和超氧阴离子自由基(·O 2 - )的作用,从而使RhB和RhB的过度氧化。 Rh-110 被抑制。因此,提出了RhB选择性氧化的瞬态保护机制来解释Rh-110的反应选择性。尽管·O 2 -和·OH在RhB的光催化选择性氧化过程中都很重要,但当·O 2 -的影响大于·OH时

    An improved method for the simultaneous sequence-specific identification of mRNAs in a mRNA population allows the visualization of nearly every mRNA expressed by a tissue as a distinct band on a gel whose intensity corresponds roughly to the concentration of the mRNA. In general, the method comprises the formation of cDNA using anchor primers to fix a 3'-endpoint, producing cloned inserts from the cDNA in a vector containing a bacteriophage-specific promoter for subsequent RNA synthesis, generating linearized fragments of the cloned inserts, preparing cRNA, transcribing cDNA from the cRNA and performing two sequence specific PCR amplifications of the cDNA. In preferred embodiments, the method comprises comparing the length and at least part of the nucleotide sequence of the PCR products to expected values determined from a database of nucleotide sequences. The method can identify changes in expression of mRNA associated with the administration of drugs or with physiological or pathological conditions. Also provided are vectors and primers useful for the practice of the improved method.

    hydroxyl radicals (·OH) and superoxide anion radicals (·O2−) at different reaction stages so that the overoxidation of RhB and Rh-110 were repressed. Therefore, the transient state protection mechanism of selective oxidation of RhB was proposed to explain the reaction selectivity for Rh-110. Although the effects of both ·O2− and ·OH are important during the photocatalytic selective oxidation of RhB,
