This paper presents a vector model of magnetization based on the three-dimensional (3-D) Stoner-Wohlfarth elemental operator. To account for the magnetic interactions between particles, a phenomenological mean-field ...
Finite-fringe interferograms produced for axisymmetric shock wave flows are analyzed by Fourier transform fringe analysis and an Abel inversion method to produce density field data for the validation of numerical models. ...
We perform theoretical calculations of the tunnelling current through various small organic molecules sandwiched between gold electrodes by using both a tunnel barrier model and an ab initio transport code. The height of ...

We have systematically investigated the diffusion mechanism of Li ions in Li2FeSiO4 and its delithiated product LiFeSiO4 based on the P21 symmetry using the first principle method. Calculations on the energy barriers for ...

Density functional molecular dynamics simulations have been carried out to understand the finite temperature behavior of Au19 and Au20 clusters. Au20 has been reported to be a unique molecule having tetrahedral geometry, ...

The adsorption of benzene molecules onto the Cu(1 1 0) surface has been studied using a crystalline linear combination of atomic orbitals approximation (LCAO). Adsorption energetics have been modelled at both the Hartree?Fock ...
Aperiodic Nanowire (NW) arrays have higher absorption than equivalent periodic arrays, making them of interest for photovoltaic applications. An inevitable property of aperiodic arrays is the clustering of some NWs into ...
Non-ultraviolet (UV) photoexposure of luminescent solar concentrators (LSC's) can produce photoproducts that cause additional extinction at wavelengths somewhat longer than the main dye absorption peak. This photo-induced ...
In this work, the acute oral toxicity of 20- and 120-nm ZnO powder at doses of 1-, 2-, 3-, 4-, 5-g/kg body weight was evaluated referred to the OECD guidelines for testing of chemicals.

In order to investigate the role of iron additive in the Ni3S2 electrode, the Ni3S2 electrode was prepared by addition of iron. The discharge properties of Na/Ni3S2 cells using 1 M NaCF3SO3 in tetra(ethylene glycol)dimethyl ...
Th adsorption energies of methanethiolate on Au(111) have been calculated using periodic density functional theory (DFT), based on the SIESTA methodology, with an internal coordination implementation for geometry input and ...

We discuss the design and fabrication of optical filters that are transparent to a preferred linear polarization, but are partially or substantially reflective to the orthogonal linear polarization. The filters are fabricated ...
A high temperature superconducting (HTS) linear propulsion system composed of a single-sided HTS linear synchronous motor (HTSLSM) in its middle and HTS magnetic suspension sub-systems on both sides has been developed. ...

Typically the grating problem is formulated for TE and TM polirizations by using, respectively, the electric and magnetic fields aligned with the grating wall and perpendicular to the plane of incidence, and this leads to ...
We study the analytic properties of the photonic crystal superprism resolution parameters p, q, and r introduced previously by Baba and Matsumoto [Appl. Phys. Lett. 81, 2325 (2002)], which characterize the potential ...
We consider the problem of localized flexural waves in thin plates that have periodic structure, consisting of a two-dimensional array of pins or point masses. Changing the properties of the structure at a single point ...
We study the propagation and localization of classical waves in one-dimensional disordered structures composed of alternating layers of left-and right-handed materials (mixed stacks) and compare them with structures composed ...

We show that no consistent scalar definition of impedance is generally possible for photonic crystals. Instead, we present a rigorous semianalytic matrix definition of impedance for square lattice photonic crystals, defined ...
A subspace of a multipartite Hilbert space is said to be locally indistinguishable if any orthonormal basis of this subspace cannot be perfectly distinguished by local operations and classical communication. Previously ...
