An Auger study of the oxidation of zinc has been carried out to confirm that the relative intensities of the metal lines in election-beam induced Auger spectra are directly proportional to the number of valence electrons and therefore of direct use in investigating surface oxidation of metals....
Based on the above analysis of the results, the related mechanism of ion release is illustrated in Fig.4. First, the ions rapidly released after 1 day come primarily from interstitial sites of PB, ZnPB-1 and ZnPB-3, because the porous of MOF can absorb a large number of metal ions, ...
Most of the chemical bonds in the perfect galena crystal are covalent bonds, and only a small number of ionic bonds. Since the internal valence charge is balanced, the adsorption ability of galena to external ions is not strong. In natural galena, due to the presence of lattice defects, ...
The linear sweep voltammetry (LSV) experiments were performed with a scan rate of 5 mV s−1at various disk rotation speeds of 400, 625, 900, 1225, and 1600 rpm. The number of electrons transferred (n) at different potentials were calculated by using Koutecky-Levich Eqs. (1)-(3...

No, zinc is not a magnetic material. Magnetism depends on a material having unpaired electrons, whose spin can extend their magnetic field. But zinc does not have unpaired electrons in the valence shell, so it is not attracted by a magnetic field.
number and intrinsic electrochemical activity of the active sites of ORR and OER catalysts are also important factors in achieving good performance of ZAB. Theoretically, the intermediate absorption energy barrier can be used to evaluate the intrinsic catalytic activity of an electrocatalyst. Several surf...
The peak at around 380 nm (E1, 3.26 eV) is attributable to the near band emission (NBE), which arises from the recombination of the electrons in the valence band (VB) of the ZnO and the holes in its conduction band (CB); the peak at 400 nm (E2, 3.1 eV) is associated with ...
Moreover, TPs molecules can effectively reduce the number of additives, which is conducive to the preservation of water-based electrolyte properties and ionic mobility (Fig. 1c). Studies showed that the introduction of TPs additive induced dense and smooth dendrite-free zinc deposition and excellent...
