The catalytic effect of the ion Zn 2+ in the degradation of the penicillins was much weaker than that of the ion Cd 2+, owing to the lesser ionic radius of the former and the fact that in the case of the reaction catalysed by Zn 2+, the compound S 2M occurred in a much greater...
According to previous reports, Zn2+ prefers to substitutionally dope RuO2 at Ru4+ sites30,48, which is readily understood by the similar ionic radius of Ru4+ (0.62 Å) and Zn2+ (0.60 Å)49. Zn-doped RuO2 retains the rutile structure of pristine RuO248, with negligible ...
Nevertheless, despite Zn2+ possessing a relatively smaller ionic radius (0.74 Å), its divalent nature, large atomic mass, and robust polarization induce the inevitable electrostatic adsorption with host materials, leading to low structural stability and sluggish Zn2+ diffusion [13], [14], [15]...
The lattice parameters increase with the increase of Znadditional amount, attributed to the larger ionic radius of the substituted ion Znthan Cuionic radius. Znsubstitution can improve the magnetic properties of CoCuZnFeO. CoCuZnFeOobtained at 800°C has the highest specific saturation magnetization ...
(Supporting Information; Table S2 and Figure S3) are consistent with the substitution of tetrahedrally coordinated Zn2+(ionic radius = 0.74 Å) into the hexagonal CdS (rCd+2= 0.97 Å) [60,61]. A gradual linear decrease in lattice parameters (a and c) with increasing zinc composition ...
On the other hand, S can easily permeate into the In(Zn)P core because there would be no such mass action as the ionic radius from the intensity of S is relatively small compared to Zn ratio of the main peaks in the S K-edge aXnAdSInsp. eTchterucmonocfenthtrea3t0io-nmriant-icooo...
[23]. As expected, shifting to the higher angle is attributed to the decrease in the lattice spacing as the Pb2+ions are incorporated into the ZnAl2O4matrix (see Fig.2c). This is due to the substitution of Zn2+(ionic radius 0.74 Å) [22] with bigger Pb2+(ionic radius 1.01–...
4.2.2Additive Electrolyte additives can not only improve ionic conductivity and broaden electrochemical voltage window, but also inhibit dendrite growth and regulate solvation structure. A variety of inorganic and organic additives is utilized for Zn ion batteries to suppress Zn dendrites and prohibits Zn...
