4A). Later studies identified a number of problems associated with the conventional configuration, such as high internal resistance, low voltage production, pH imbalance and microbial inhibition due to migrated ions, membrane fouling and scaling, and migration of non-selective ions (Cao et al., ...
The 1,3-elimination of methoxide by carbanions generated from the reaction of (±)-1,3-dimethoxy-1,1-diphenylbutane with the alkali metals, lithium, sodium, and potassium, in various solvents was studied to determine the significance of cation–methoxyl coordination due to decreasing charge/...
The ground state was found to be a singlet, with no unpaired electrons on the yttrium ions and an iron(II) electronic configuration, in agreement with the oxidation states derived from the XANES measurements. As depicted in Fig. 5, inspection of the Kohn–Sham frontier molecular orbitals ...
2D electrode materials are often deployed on conductive supports for electrochemistry and there is a great need to understand fundamental electrochemical processes in this electrode configuration. Here, an integrated experimental-theoretical approach is used to resolve the key electronic interactions in outer...
Electron Transition: One of the responses of an atom to the removal or supply of energy is the transition of electrons from a lower energy level to a higher energy level or the reverse. The transition depends on the amount of energy removed or supplied. ...
