The charge distribution

In the present report, a novel concept of frequency response function (FRF) is introduced for piezoelectric beam. First, a model of Timoshenko beam bonded with a piezoelectric layer is established and used for deriving the conventional frequency response function acknowledged as mechanical frequency response function (MERF). Then, the output charge produced in the piezoelectric layer is calculated from the MFRF and therefore obtained frequency-dependent function is called electrical frequency response function (EFRF) for the integrated beam.

Three chalcones with a 2,3-dihydrobenzofuran linkage were analyzed by applying the density functional theory (DFT) and B3LYP approach with the 6-311G(d,p) basis set in this report. Spectroscopic and theoretical analyses were used to examine the structures of these three chalcones. The chalcone molecules' HOMO-LUMO energy was determined. Chemical reactivity parameters and molecular electrostatic surface potential (MESP) plots were obtained to gain useful insight into the distribution of charge density.

Ebook "Modern charge-density analysis" focuses on state-of-the-art methods and applications of electron-density analysis. It is a field traditionally associated with understanding chemical bonding and the electrostatic properties of matter. Recently, it has also been related to predictions of properties and responses of materials (having an organic, inorganic or hybrid nature as in modern materials and bio-science, and used for functional devices or biomaterials).

Ebook "Reactions of solids with gases (Comprehensive chemical kinetics, Volume 21)" addresses collision energy transfer and the effects it has on gas phase reactions, particularly at low gas density. Such systems include combustion, industrial gas phase processes and atmospheric/environmental processes. The book also discusses The Master Equation to give a good overview of the mechanics underpinning unimolecular kinetics. This new volume will be of interest to researchers investigating gas phase processes which involve unimolecular reactions and the related intermolecular reactions.

This thesis is dedicated to study how the charging behaviours of plug-in hybrid vehicles affect the local distribution network. This study focuses on two issues: the power loss and charging cost optimization. The multi-objective particle swarm optimization technique is applied to achieve the optimal charging schedule, resulting in acceptable additional power loss ratio and charging cost.

Poor induction of mucosal immunity in the intestines by current Salmonella vaccines is a challenge to the poultry industry. We prepared and tested an oral deliverable Salmonella subunit vaccine containing immunogenic outer membrane proteins (OMPs) and flagellin (F) protein loaded and F-protein surface coated chitosan nanoparticles (CS NPs) (OMPs-F-CS NPs). The OMPs-F-CS NPs had mean particle size distribution of 514 nm, high positive charge and spherical in shape.

In the study "Structural and electronic properties of germanene adsorbing O2, N2, and H2 gases: A DFT study" DFT calculations under van der Waals corrections are utilized to investigate the adsorption mechanism of the O2, N2 and H2 gases on germanene. The first-principles physical quantities are sufficiently developed to determine the structural and electronic properties, including the adsorption energies, optimal structural parameters, the electronic band structures, the charge density distribution.

In the study "Comparison of determining the 10B and 6Li depth profiles based on NDP and SIMS analytical methods" the comparison of the analytical results between SIMS (Secondary-ion mass spectrometry) and NDP (Neutron Depth Profiling) methods have been carried out with LiCoO2 and BSi samples. The NDP is an analytical method to analyze the component nuclide concentration versus depth distribution in a sample by detecting the charged particles emitted after the neutrons are absorbed.

Previous studies have observed mineral specific variations in the ratios of IRSL signals stimulated at the different discrete wavelengths of lines corresponding to Xe lamp emission lines, which fall within the broad excitation spectrum of IRSL. Meanwhile recent accounts of IRSL have referred to single trapping systems within the excitation band, and modelled excitation spectra as continuous gaussian distributions.

Spatially resolved optically stimulated luminescence (OSL) offers a means for rapid assessment of dose distributions in retrospective dosimetry and geochronology. Until recently, OSL imaging systems have largely been restricted to measurements of millimetre scale samples; this approach is not well suited for applications where the physical process of interest operates on centimetre scale (e.g., depth dependent trap eviction in exposed rocks, sediment mixing in soils, attenuation of gamma radiation, etc.).

In this paper, we propose a globally optimal scheduling scheme and a locally optimal scheduling scheme for EV charging and discharging. We first formulate a global scheduling optimization problem, in which the charging powers are optimized to minimize the total cost of all EVs which perform charging and discharging during the day. The globally optimal solution provides the globally minimal total cost.

Immobilized metal chelate affinity chromatography (IMAC) support was practiced for α-amylase immobilization. Poly(hydroxyethylmethacrylate-methacryloylamidotryptophan)-Ni2+[p(HEMA-MAT)-Ni2+] nanospheres, average diameter 100 nm, were produced by surfactant free emulsion polymerization. Characterizations of p(HEMAMAT)-Ni2+ nanospheres were carried out by Fourier transform infrared (FTIR) spectroscopy and scanning electron microscope (SEM). In addition, average particle size, size distribution, and surface charge were specified.

A new double molybdate Na2Co2(MoO4)3 was synthesized via solid-state reaction and characterized by single-crystal X-ray diffraction (XRD). This compound is a new member of the lyonsite structure type. It crystallized in the orthorhombic system, space group Pnma with cell parameters a = 5.272(2) Å, b = 10.816(3) Å, and c = 18.064(3) Å. The structure can be described as a three-dimensional framework with hexagonal tunnels in which the Na+ cations lie. The obtained structural model is supported by charge distribution analysis and bond valence sum validation tools.

The simplest ideas of antiaromaticity refer to regular monocyclic systems and the eigenfunctions of the Hückel Hamiltonian for 4n π electrons in such systems. The antiaromaticity is expressed in the energy penalty for such idealized systems relative to the Hückel energy for 2n noninteracting π pairs. Observed systems seldom achieve the regular planar geometry assumed in this picture, owing to their ability to ease the antiaromaticity penalty by departures from the regular geometry and also by export of the 4n π electrons’ charge to substituents.

Amorphous lithium niobate (LiNbO3) films were deposited onto silicon substrates by the radiofrequency magnetron sputtering method in a pure Ar environment and an Ar þ O2 gas mixture with various oxygen contents. The oxide charge existing in as-grown films has two components: the positive Qox distributed in the bulk of a film and the negative Qox located at the film/substrate interface with a maximum magnitude corresponding to an Ar (80) O2 (20) gas mixture.

The Charged Hard Sphere (CHS) reference system is applied to study the structural analysis of liquid 3d transition metals. Here we report the structure factor S(q), pair distribution function g (r), interatomic distance r1 of nearest neighbour atoms and coordination number n1 for liquid 3d transition metals viz: Ti, V, Cr, Mn, Fe, Co, Ni and Cu. To describe electron–ion interaction our own model potential is employed alongwith the local field correction due to Sarkar et al (SS). The present results of S(q) and g (r) are in good agreement with experimental findings.
