CV studies indicated that the oxidation process has an irreversible and diffusion-like behavior in an oxidation mechanism with an equal number of electrons and protons. A possible reaction mechanism was proposed. Square-wave voltammetry (SWV) was applied as a very sensitive voltammetric detection ...
instability occurs when there is an imbalance in the number of protons and neutrons in the atomic nucleus. Basically, there is too much energy inside the nucleus to hold all the nucleons together. The status of the electrons of an atom doesn't matter...
More importantly, the outermost layer of iron atom contains five electrons similar to gadolinium, which can change the relaxation time of protons and engender greater r 1 and r 2 relaxation effects, thus showing certain potential in MRI applications [21]. So far, there are three kinds of iron...
4. Neutralization of O•−2O2•− by protons: O•−2+H+→HO•2O2•−+H+→HO2• (36) 5. Transient hydrogen peroxide formation and dismutation of oxygen: 2HO•2→H2O2+O22HO2•→H2O2+O2 (37) 6. Decomposition of H2O2H2O2 and the second reduction of oxygen: H2O2...
Contrast agents have been used to enhance the contrast and improve the resolution of diagnostic MRI by reducing either the longitudinal (T1) or transverse (T2) relaxation time of water protons. Consequently, two types of contrast agents, T1 and T2, enhance the positive (bright signal) or ...

of Cl−during seawater splitting, and the stability of the photoanode can be effectively improved by enhancing the metal-oxygen interaction. Taking the metastableβ-Fe2O3photoanode as an example, Sn added to the lattice can enhance the M–O bonding energy and hinder the transfer of protons ...
, the Ti4+ and Sn4+ ions have been predominantly used in mono- or co-doped configurations9. However, from quantum mechanical point of view, the electron transport in hematite with Zr doping is superior compared to Ti17, because Zr4+ does not trap electrons due to a low ionization ...
G Assanto,NF Smyth - 《IEEE Journal of Selected Topics in Quantum Electronics》 被引量: 4发表: 2015年 Solitary waves in plasmas We shall now discuss the propagation of electromagnetic waves through a hydrogen plasma – an electrically neutral fluid of protons and electrons. This will allow us...
The binding of the substrates sodium laurate and sodium 12-bromolaurate to the heme-containing domain of Bacillus megaterium cytochrome P-450 (BM3) (CYP102) has been studied by measurement of the relaxation effects of the unpaired electrons of the heme iron on the protons of water and of the...
