Total cross sections (TCSs) of electrons scattering from triatomic molecules over the energy range from 30 to 5000 eV are investigated employing a new semi-empirical formula. The TCSs of electrons scattering from triatomic molecules SO2, NO2, and CO2 are calculated. The quantitative TCSs are in ...
itself to call this what is is — a “Solar Glut” dumped on the grid. Instead rooftop solar is a “juggernaut” and the grid faces a “low demand warning”, as if you personally are the problem, for not using enough electrons. Don’t blame the artificial pointless ...
Even though both could donate electrons in the redox reaction with I-2, the former was considered a greater contributor for the RC of hydrochar. From this study, the origin of RC of hydrochar can be identified as: oxygen-containing functionality, humic-like matter and PFRs. By e...

(seeSections 2.1 and 2.2). Fundamentally, a semiconductor catalyst is irradiated with the photon energy, resulting in the excitation of electrons (e−) from the valence band to the conduction band, leaving a hole (h+) behind in the conduction band. In typical water-splitting mechanisms, the...
