Chromium (Cr) - The Electron Configuration of Chromium is [Ar]3d54s1. Chromium is a Lustrous, Hard metal which has a Silver-Gray Color. Learn about Chromium Element and its Properties and Uses.
The kinetic stability of Cr(III)/HS complexes could be explained by the d 3 electron configuration of Cr 3+ ions, a fact which is well known from classical Cr(III) complexes, and influences substantially the mobility of this heavy metal in the environment....
and chromate-based compounds on the graphene as an idealized configuration for AC. Materials and methods Materials Zinc-chloride (ZnCl2), potassium dichromate (K2Cr2O7-molecular weight (MW) = 294.19 g, an assay of 99%)), ethanol (C2H5OH), and urea (NH2CONH2), were procured from Sigma ...
The laser fluence is calculated from the equations explained in the Methods section. Furthermore, we have analyzed the structures using the Lumerical device software package to see the thermal distribution in the nano-antennas, and as an example the distribution of temperature for gold antenna is ...
Moreover, we demonstrate that this contrasting behavior can be explained only by the nature of magnetic coupling of the impurities to the Fe matrix. Specifically, Cr interaction with the dislocation core mirrors that of Ni if the Cr magnetic moment is constrained to be along the direction of ...
Thus, the difference in plateau current density between iron and chromium metal may be explained where ORR on the bare iron surface proceeds predominantly via the 4e− O2 pathway, Eq. (7), but proceeds on the oxide covered chromium metal via the 2e− pathway, Eq. (8). However, no ...
Contamination by hexavalent chromium has had a large impact on modern society and human health. This problem is a consequence of its great industrial appli
Two types of thermal hysteresis are seen in both longitudinal and Hall resistivity: the first can be explained by the quantization of spin density waves due to the finite film thickness (confirmed by X-ray diffraction measurements) and the second by domain-wall scattering of electrons. We also ...
Presence of Pt as co-catalyst yielded decrease of electron transfer resistance more than in the case of Pd particles. Accordingly, it can be concluded that Pt-CT electrodes have better electrical conductivity under light illumination, which can be assigned to the surface plasmon resonance effect ...
