The meaning of GROUP is two or more figures forming a complete unit in a composition. How to use group in a sentence.
aAdditionally, most of the known examples feature two or more atoms between an NHC nitrogen and a diphenylphosphino group, leading to rather flexible, often hemilabile metallacycles 另外,大多已知的例子以两个或多个原子为特色在NHC氮气和diphenylphosphino小组之间,导致相当灵活,经常hemilabile metallacycles...

A functional group is a specific group (moiety) of atoms in a molecule, such that the group is responsible for the characteristic chemical reactivity of the molecule. From: Carbon Composites (Second Edition), 2017 About this pageAdd to MendeleySet alert Also in subject areas: Chemical Engineerin...
MTs exhibit the capacity to simultaneously complex with seven zinc (Zn2 +) atoms. Zn2 + is a potent second messenger that potentiates signaling through mitogen-activated protein kinase (MAPK) pathways that drive cell proliferation, differentiation and resilience, thus MT sequestration of Zn2 + ...
The present invention relates to a method for dividing two or more\nmore inorganic ions from the group of elements\nrare earths. To the starting solution containing\nsoluble salts of rare earth elements are acting\ncomplexing organic acid containing\none or more carboxyl groups\nand not more ...
Maps are studied, i.e., cell decompositions of closed two-dimensional surfaces, or two-dimensional atoms which encode bifurcations of Liouville fibrations of non-degenerate integrable Hamiltonian systems. Any finite group is proved to be a symmetry group of an orientable map (of an atom). More...
A quantum optics model of the asymmetric case of the interaction between two two-level atoms and quantum field, which obeys SU(1,1) Lie group, is proposed. The atom-atom interaction and the rotating wave approximation are suggested in the Hamiltonian operator. Our aim is to obtain the time...
