Abstract The importance of the electric potential along field direction in acceleration electrons quasi-perpendicular bow shock has been proposed. Nevertheless, mechanism by which are accelerated remains unclear from perspective situ observation. In this study, utilizing data obtained Magnetospheric Multiscale mission, we identify a double layer (DL) located within transition shock. It is found...

Single crystals of the title compounds were prepared by solid-solid reaction using BaCl2 or BaBr2 flux at 1100°C. The structures of these two new cobaltites were solved and refined in the trigonal symmetry with space group R3 m: a=5.716(2) Å, c=45.01(3) Å for Ba2Co4ClO7 and a=5.7434(5) Å, c=46.151(9) Å for Ba2Co4BrO7. The two compounds are isostructural and their structures can be considered as...

Aiming to introduce a multiresidue analysis for the trace detection of pesticide residues belonging to organophosphorus and triazine classes from olive oil samples, a new sample preparation methodology comprising the use of a dual layer of "tailor-made" molecularly imprinted polymers (MIPs) SPE for the simultaneous extraction of both pesticides in a single procedure has been attempted. This wor...

We present measurements of transmission of infrared radiation through double-layer metallic grating structures. Each metal layer contains an array of subwavelength slits and supports transmission resonance in the absence of the other layer. The two metal layers are fabricated in close proximity to allow coupling of the evanescent field on individual layers. The transmission of the double layer ...

A model for ionic solutions with an attractive short-range pair interaction between the ions is presented. The short-range interaction is accounted for by adding a quadratic nonlocal term to the Poisson-Boltzmann free energy. The model is used to study solvent effects in a planar electric double layer. The counterion density is found to increase near the charged surface, as compared with the Po...

When two charged surfaces and their accompanying electrical double layers (EDLs) approach each other in an electrolyte solution, the EDLs first begin to overlap and finally collapse under confinement. During this collapse we can observe repulsive forces and film-thickness transitions, which contain valuable information about different structural elements present at the interface. Sensing and di...

We study the mean-field Poisson-Boltzmann equation in the context of dense ionic liquids where steric effects become important. We generalise lattice gas theory by introducing a Flory-Huggins entropy for ions of differing volumes and then compare the effective free energy density to other existing lattice gas approximations, not based on the Flory-Huggins Ansatz. Within the methodology presente...

Abstract. A new model for the study of one-dimensional walls in magnetic multilayers is presented. We obtain the optimal scaling of this energy functional for low anisotropy double layers with magnetic layers of equal thickness. We prove that he optimal scaling may be attained by opposing Néel walls. We obtain the core length of the Néel wall, and a detailed description of its structure. We ill...

This paper addresses the challenges of fitting asymmetric photoelectron peaks by showing that use double Lorentzian (DL) line shape usually leads to high-quality, reliable, and reproducible fits. In contrast Doniach-Sunjic (DS) shape, used fit peaks, DL distribution is integrable produces higher-quality The functional form described in detail; examples application DS transition metals one metal...

System Area Networks (SANs), which usually accept irregular topologies, have been used to connect nodes in PC/WS clusters or high-performance storage systems. Since wormhole or virtual cut-through transfer is used for low latency communication, deadlock-free routings are essential in SANs. In this paper, we propose a novel deadlock-free deterministic routing called descending layers (DL) routin...
