The rest mass of an electron is the mass of a stationary electron, also known as the electron invariant mass. The charge to mass ratio of electron is e/m is the ratio between the charge of the electron by the mass of the electron which is 1.758820 - 10^1
Influence of confinement energy and band anticrossing effect on the electron effective mass in Ga1-yInyNxAs1-x quantum wells DOI: http://dx.doi.org/10.1103/PhysRevB.71.233301 S Tomic,E O’Reilly - 《Phys.rev.b》 被引量: 59发表: 2005年 How Does Chemistry Influence Electron Effective Mas...
We believe that all these factors have contributed to the fact that the chemistry of the long-range FA cross-link has not been characterized correctly. In light of the findings, we suggest the following mechanism of FA cross-linking (Fig. 5). The reaction starts with the accepted imine ...

The cation [Ge,C,H]+ has been generated by the electron ionisation of trichloromethylgermane. Collisional activation experiments were used to establish a Ge–C–H connectivity in this species, for which a significant fraction of the ion population was found to survive neutralisation-reionisation m...
In subject area: Chemistry Electron impact mass spectrometry (EI-MS) involves the bombardment of the vaporized metabolite by high-energy electrons (0–100eV), producing a molecular radical cation (M+·) having a mass equivalent to the molecular weight of the compound. ...
The electron ionization (EI) mass spectra of a series of bridgehead-substituted 3,3-dimethylnorbornan-2-ones, derived from natural (1R)-(+)-camphor, have been studied and their cleavage mechanisms rationalized on the basis of the substituent shifts as well as on the identification of relevant...

Microbiotas are a malleable part of ecosystems, including the human ecosystem. Microorganisms affect not only the chemistry of their specific niche, such as the human gut, but also the chemistry of distant environments, such as other parts of the body. Mass spectrometry-based metabolomics is one...
