In addition, the utility of various tellurium- and selenium-containing heterocycles are summarized. Primarily, the synthesis of tellurium- and selenium-containing heterocycles of five- and six-membered rings are described with various degrees of unsaturation, as well as their benzo-fused analogues. In...
Chemical transformations that introduce, remove or manipulate functional groups are ubiquitous in synthetic chemistry1. Unlike conventional functional-group interconversion reactions that swap one functionality for another, transformations that alter solely the location of functional groups are far less explored...
Functional groups .In organic chemistry, functional groups are specific groups of atoms within molecules that are responsible for the characteristic chemical reactions of those molecules. The same functional group will undergo the same or similar chemical reaction(s) regardless of the size of the ...

As demonstrated in Fig. 1c, HCl treatments can tune the density of functional groups, which thereby generates various voltage outputs. The cycling stability of the device is another key parameter determining MEG performance. In this work, moisture was carried by N2 gas to the top surface of ...
Density-Functional Theory of Atoms and Molecules (International Series of Monographs on Chemistry) 2024 pdf epub mobi 用户评价 评分☆☆☆ 这本书的 appendix A 应该撕下来单独卖给刚学分析力学/刚学经典场论的人读。分析力学做变分的时候常常有人直接把泛函微分当偏导看,这进行到场论会导致一大堆错误理解,...
Nature Chemistry10,85–90 (2018)Cite this article 11kAccesses 47Citations 13Altmetric Metrics Abstract The selective (and controllable) modification of complex molecules with disparate functional groups (for example, natural products) is a long-standing challenge that has been addressed using catalysts ...
Untargeted metabolomic approaches are performed through collecting all mass spectra and using bioinformatics tools (e.g., XCMS) to identify, integrate, and compare ions among comparison groups. Both targeted and untargeted functional metabolomic approaches have recently revealed the functions of previously ...
