Computational Analysis of Electrochemical Behavior and Fullerene-Based Adsorbents for Extraction of Acetamiprid [PDF]

open access: yesIranian Journal of Chemistry & Chemical Engineering, 2023
Using density functional methods, the results of the analysis of traditional adsorbents and adsorbents based on nanosized particles capable of trapping acetamiprid molecules in fruits and plants are presented.

Improved calculations of mean ionization states with an average-atom model

open access: yesPhysical Review Research, 2023
The mean ionization state (MIS) is a critical property in dense plasma and warm dense matter research, for example, as an input to hydrodynamics simulations and Monte Carlo simulations.

Zintl Salts Ba2P7X (X = Cl, Br, and I): Synthesis, Crystal, and Electronic Structures

open access: yesCrystals, 2013
Two barium phosphide halides, Ba2P7Br and Ba2P7I, were synthesized and structurally characterized by single crystal X-ray diffraction. Both compounds crystallize in the monoclinic space group P21/m (No. 11) and are isostructural to Ba2P7Cl.

Electron States on the Rough GaAs (100) Surface, Formed by the Surface Acoustic Wave and Adsorbed Atoms [PDF]

open access: yesЖурнал нано- та електронної фізики, 2017
The theory of electron states is developed on the adsorbed surface of semiconductor which is bounded by the rough surface. The surface roughness are formed by both quasi-Rayleigh acoustic wave and adsorbed atoms.

Local representation of the electronic dielectric response function

open access: yesPhysical Review B, 2015
We present a local representation of the electronic dielectric response function, based on a spatial partition of the dielectric response into contributions from each Wannier function using a generalized density functional perturbation theory. This procedure is fully ab initio, and therefore allows us to rigorously define local metrics, such as "bond ...

Electron localization function from density components [PDF]

open access: yesJournal of Computational Chemistry, 2016
This work addresses the decomposition of the Electron Localization Function (ELF) into partial density contributions using an appealing split of kinetic energy densities. Regarding the degree of the electron localization, the relationship between ELF and its usual spin‐polarized formula is discussed.

Understanding the Molecular Mechanism of the Rearrangement of Internal Nitronic Ester into Nitronorbornene in Light of the MEDT Study

open access: yesMolecules, 2019
The characterization of the structure of nitronic esters and their rearrangement into nitronorbornene reactions has been analyzed within the Molecular Electron Density Theory (MEDT) using Density Functional Theory (DFT) calculations at the B3LYP/6-31G(d)

Electron Localization Function for Noncollinear Spins

open access: yesPhysical Review Letters
Understanding of bonding is key to modelling materials and predicting properties thereof. A widely adopted indicator of bonds and atomic shells is the electron localization function (ELF). The building blocks of the ELF are also used in the construction of modern density functional approximations.
