Abstract:
Model of the surface dimer formed by coupling adsorbing atom and surface substrate atom by covalent bond is proposed. This model is used for the calculations of the charge transfers between dimer’s atoms and between dimer and graphene substrate. Effects of Coulomb and electron-phonon interaction on charge transfers are thoroughly studied. Role of inter-adatoms dipole-dipole repulsion and exchange interactions are examined. Adsorption on epitaxial graphene is briefly discussed.

Abstract:
During the meandering motion of a dipolar vortex on a β-plane mass is exchanged both between the dipole and the ambient fluid and between the two dipole halves. The mass exchange (as well as the meandering motion) is caused by variations of the relative vorticity of the vortices due to conservation of potential vorticity. Previous studies have shown that a modulated point-vortex model captures the essential features in the dipole evolution. For this model we write the equations of motion of passive tracers in the form of a periodically perturbed integrable Hamiltonian system and subsequently s

Abstract:
We present a set of equations expressing the parameters of the magnetic interactions of an electronic system. This allows to establish a mapping between the initial electronic system and a spin model including up to quadratic interactions between the effective spins, with a general interaction (exchange) tensor that accounts for anisotropic exchange, Dzyaloshinskii–Moriya interaction and other symmetric terms such as dipole–dipole interaction. We present the formulas in a format that can be used for computations via Dynamical Mean Field Theory algorithms.

Abstract:
Dipole–exchange spin waves (SWs) are studied in ferromagnetic nanostructures with spherical geometries such as spheres, part spheres, and spherical shells, both individually and in finite-sized arrays. A microscopic theory is used based on a spin Hamiltonian, which incorporates the short-range exchange and long-range magnetic dipole–dipole interactions, as well as an external magnetic field applied in any direction. Our theory is advantageous for describing the dynamical properties of inhomogeneously magnetized samples, and the use of phenomenological boundary conditions is avoided. Numerical

In the paper, dipole-exchange spin excitations in a composite nanorice-type nanoparticle (prolate rotation ellipsoid) are investigated theoretically. A nanorice with a non-magnetic core and a shell composed of an uniaxial ferromagnet is considered. Spin dynamics in the above-described nanosystem is described using the linearized Landau-Lifshitz equation (in the magnetostatic approximation) with the addends that consider the magnetic dipole-dipole interaction, the exchange interaction and the anisotropy effects. An equation for the magnetic potential of the above-described spin excitations is

Abstract:
Abstract A transient, one-dimensional, model of the membrane of a proton exchange membrane fuel cell is presented. The role of the membrane is to transport protons from the anode to cathode of the fuel cell while preventing the transport of other reactants. The membrane is modeled assuming mono-phase, multi-species flow. For water transport, the principle driving forces modeled are a convective force, an osmotic force (i.e. diffusion), and an electric force. The first of these results from a pressure gradient, the second from a concentration gradient, and the third from the migration of proton

Abstract:
Abstract Quaternary Cationic Biocides (ammonium and phosphonium based) are broad spectrum and fast acting. Due to their compatibility, low cost, and high effectiveness, they are often used as biocides in oil and gas operations alone and also as formulation components for multi-biocide packages. They have also found use as additives in corrosion inhibitor formulations, emulsifiers, nonemulsifiers, and even as scale inhibitors. While they tend to work well in fresh water where there is little to no salt present, they are shown to provide decreasing performance as the salt concentration increases
