The significance of secondary metabolites as antimicrobial agents and its chemistry in the drug development process is reviewed. The genus Anogeissus (Combretaceae) is widely distributed in most tropical and subtropical countries of the world. Anogeissus is a genus of trees, shrubs or small trees....

Meanwhile, highly stable Zn plating/stripping for over 1500 h, an average coulombic effi-ciency of >99% in long-term cycling, and ultralong storage life (the cells can work well after stored over 1 year) are simultaneously realized in the novel electrolyte. Benefitting from these aspects, ...
This review will discuss recent progress in the chemistry of secondary polyphenols produced during food processing. The production mechanism of the secondary polyphenols in black tea, whisky, cinnamon, and persimmon fruits will be introduced. In the process of black tea production, tea leaf catechins...
When tested in Li||LiFePO4 cell, this electrolyte provides long-term cycling with a capacity retention of 98.3% after 1000 cycles at 1 C and an excellent rate performance of 20 C, as well as an areal capacity of 1.35 mA h cm-2 at the cathode areal loading of 9 mg cm-2. Moreover,...
