thus, posit designing ultrafine iron-based NP/graphene oxide composite membranes for advanced reduction of HAAs, which provide nanoconfinement effects to achieve reduced activation energy for the formation of reducing radicals for DCAA dechlorination. Furthermore, the reductants, including S(IV) and cont...
Metals are defined as those elements which have characteristic chemical and physical properties. The familiar types of metals are (iron, aluminium, copper, lead, zinc, silver, gold, etc.) are common elements.
Calculations of complete energy level schemes for 4 f n and 4 f n 1 5 d 1 electronic configurations of free trivalent rare-earth ions have been performed. Semi-empirical Hamiltonian was used for the calculation of 4 f n configuration while a fully relativistic first-principles many-electro...
An ionic compound is composed of a metal cation and a nonmetal anion. The transfer of electron/s from the cation to the anion creates the electrostatic force of attraction which creates the ionic bond. Answer and Explanation:1 In an ionic compound, the cation...

The last structure was discussed as an electron transfer between the O 2𝑝2p valence band and the Fe 4𝑠4s conduction band. Such assignment was confirmed by the derivation of the crystal field splitting energy for both octahedral and tetrahedral iron ions, respectively. The obtained energies ...
Among the metal oxide nanostructures, iron oxide has promising applications for cancer biomarkers detection due to its fast electron-transfer kinetics, strong adsorption, high surface-to-volume ratio, non-toxic nature, and biocompatibility [75]. Carbon nanomaterials include graphene, fullerenes, multi-...
For the two highest switching frequencies (30 kHz for Si-IGBT and 100 kHz for SiC-MOSFET), the SiC-MOSFET-based converter can offer the reduction of 73% of the core volume for alloy core, and 77% for the iron core, having around 60% lower cost. In this case, the best compromise ...
