Previously we have shown that POCl3-mediated H-bonding-directed one-pot macrocyclization allows for the highly selective preparation of five-residue macrocycles as the predominant product with low yie
Antisense oligonucleotides(ASONs) and siRNAs have been applied extensively for the regulation of cellular and viral gene expression,and RNAi is currently one of the most promising new approaches for a
Modified deoxy-and ribo-nucleoside triphosphates are chemically synthesized in multiple steps due to the protection and deprotection of the nucleoside functionalities.To conveniently synthesize the S-
The gene product Sll1127 is a predicted 1,4-dihydroxy-2-naphthoyl-CoA synthase catalyzing an intramolecular Claisen condensation in the phylloquinone biosynthesis of the cyanobacterium Synechocystis s
The sustainable development of our future represents an unorthodox challenge in sciences and technologies.The exploration of unconventional chemical reactivities that could potentially result in more
The interfacial electron transfer(IET) dynamics of single CdSe core/multilayer shell(CdS2MLZnCd-S1MLZnS1ML) quantum dots(QDs) on the(110) surface of a rutile TiO2 single crystal and TiO2 nanoparticles
通过煤的部分气化制备了煤在不同加热终温下的半焦,详细分析了原煤和不同半焦的干燥无灰基挥发分含量,提出预测煤部分气化后生成半焦残余挥发分含量的新方法,即采用两个燃料特性参数FV和FC来分别表征挥发分二次析出特征温度和完全析出时的特征温度,这样根据原煤的工业分析和元素分析数据,就可以简单可靠地预测不同加热终温下所制得半焦中的残余挥发分含量.
Volatile organic solvents were considered to have little influence on the synthesis of mesostructured materials through evaporation-induced self-assembly(EISA),because upon evaporation they leave the
Photochemical and thermal isomerization of various azobenzenes was systematically investigated to understand the correlation between the molecular structure and transcis isomerization characteristics
