Active cloaking and illusion of electric potentials in electrostatics [PDF]

Scientific Reports, 2021
AbstractCloaking and illusion has been demonstrated theoretically and experimentally in several research fields. Here we present for the first time an active exterior cloaking device in electrostatics operating in a two-horizontally-layered electroconductive domain, and use the superposition principle to cloak electric potentials.

Identification of the Tetrel Bonds between Halide Anions and Carbon Atom of Methyl Groups Using Electronic Criterion

Molecules, 2019
The consideration of the disposition of minima of electron density and electrostatic potential along the line between non-covalently bound atoms in systems with Hal−···CH3–Y (Hal− = Cl, Br; Y = N, O) fragments ...

Self-Consistent Parameterization of DNA Residues for the Non-Polarizable AMBER Force Fields

Life, 2022
Fixed-charge (non-polarizable) forcefields are accurate and computationally efficient tools for modeling the molecular dynamics of nucleic acid polymers, particularly DNA, well into the µs timescale.

ELECTROKINETIC PROPERTIES, IN VITRO DISSOLUTION, AND PROSPECTIVE HEMOAND BIOCOMPATIBILITY OF TITANIUM OXIDE AND OXYNITRIDE FILMS FOR CARDIOVASCULAR STENTS

Бюллетень сибирской медицины, 2015
A state of titanium oxide and oxynitride coatings on L316 steel has been studied before and after their contact with model biological fluids. Electrokinetic investigation in 1 mmol potassium chloride showed significant (more than 10 times) fall of ...

Theoretical Studies on the Role of Guest in α-CL-20/Guest Crystals

Molecules, 2022
The contradiction between energy and safety of explosives is better balanced by the host–guest inclusion strategy. To deeply analyze the role of small guest molecules in the host–guest system, we first investigated the intermolecular contacts of host and

Implications of electrostatic potentials on ribosomal proteins [PDF]

Nucleic Acids Research, 1976
Potentiometric studies of ribosomal particles 30S, 50S, and 70S, were designed to investigate possible implications of the electrostatic potentials developed by the 16S and 23S rRNA fractions. Release of protons and proton titrations of these ribosomal fractions were examined as a function of Mg2+ and K+ concentrations. The effects of these cations fit

Enantioseparation of 5,5′-Dibromo-2,2′-dichloro-3-selanyl-4,4′-bipyridines on Polysaccharide-Based Chiral Stationary Phases: Exploring Chalcogen Bonds in Liquid-Phase Chromatography

Molecules, 2021
The chalcogen bond (ChB) is a noncovalent interaction based on electrophilic features of regions of electron charge density depletion (σ-holes) located on bound atoms of group VI.
