Nanocomposites for Decontamination of Multicomponent Technogenic Dilutions
Employing model solutions we have tested a new technological method of neutralization of multi-metal containing effluences including low radioactive ones. The proposed approach seamlessly combines the positive properties of both physical chemical methods and nanotechnology using silica-magnetite nanocomposite SiO2/Fe3…
New Bismaleimide-Silica Hybrid Materials: A Critical Assessment of Properties in Correlation with the Method of Synthesis
New hybrid materials have been prepared by sol–gel technique. They have been obtained from bismaleimide monomers either in reaction with N-(3-triethoxysilylpropyl)furan-2-carboxamide monomer, by a Diels–Alder reaction, or in reaction with (3-aminopropyl)triethoxysilane following a Michael addition reaction. The sol–ge…
Features of Ferroelectric States in the Simple-Perovskite Mixed-Oxide System (1−x)Pb(Zn1/3Nb2/3)O3–xPbTiO3 with Lower Ti Contents
A mixed-oxide system (1 − x)Pb(Zn1/3Nb2/3)O3–xPbTiO3, which has a simple perovskite structure, has been reported to exhibit remarkable piezoelectric responses for 0 < x ≤ 0.08. To understand the ferroelectric states for 0 < x < 0.10, the crystallographic features of plate-shaped single crystals with various sample ori…
Multiphysics modeling of multiferroic artificial materials by the finite element method
This paper proposes an investigation of the magnetoelectric (ME) effect of multiferroic artificial ME composite combining a piezoelectric matrix medium incrusted of magnetostrictive particles. The modeling has been performed on a 0-3 type multiferroic artificial ME composite in using a multiphysics code based on the f…

Catalytic Destruction of a Surrogate Organic Hazardous Air Pollutant as a Potential Co-benefit for Coal-Fired Selective Catalytic Reduction Systems
Catalytic destruction of benzene (C 6 H 6 ), a surrogate for organic hazardous air pollutants (HAPs) produced from coal combustion, was investigated using a commercial selective catalytic reduction (SCR) catalyst for evaluating the potential co-benefit of the SCR technology for reducing organic HAP emissions. Bench-sc…
Comment on “Temperature dependence of atomic vibrations in mono-layer graphene” [J. Appl. Phys. 118, 074302 (2015)]
In an interesting recent study [Allen et al., J. Appl. Phys. 118, 074302 (2015)] (see also their Erratum [Allen et al., J. Appl. Phys. 118, 159902 (2015)]), Allen and co-workers measured the mean square amplitudes of graphene lattice vibrations between 100 and 1300 K and used a simplified theoretical approximation for…
Spin polarisation using gate voltage through a Rashba barrier in graphene
Abstract Gate-tunable spin-resolved scattering through a Rashba spin–orbit (SO) coupling graphene barrier is considered theoretically by using a mode-matching method. In this structure, we investigate the dependence of the tunnelling transmission probability on the spin orientation of the incident electron. It is foun…
El crecimiento en los extremos: reactividad de grupos terminales en polímeros para la síntesis de copolímeros bloque
Tres diferentes tipos de reacciones utilizando grupos terminales en polímeros fueron analizados para la síntesis de copolímeros dibloque, tales como: a) los grupos azida (R N3) y el alquino (R C CH) para obtener una cicloadición 1,3-dipolar (química clic); b) los polí- meros ,−hidoxi-telequélicos (HO R OH) y los diiso…
Temperature-dependent recombination velocity analysis on artificial small angle grain boundaries using electron beam induced current method
The details of the process of carrier recombination via the Shockley-Read-Hall (SRH) defect level, at the grain boundaries of multicrystalline silicon, were investigated. For this, the temperature-dependent recombination velocities, as determined by experiments, were analyzed by the application of an electron beam ind…

Scanning electron microscopy showed internal multiple hollows was f…
Topological modification of the electronic structure by Bi-bilayers lying deep inside bulk Bi 2 Se 3
We observe the modified surface states of an epitaxial thin film of a homologous series of (Bi2)m(Bi2Se3)n, as a topological insulator (TI), by angle-resolved photoemission spectroscopy measurements. A thin film with m : n = 1 : 3 (Bi8Se9) has been grown with Bi2 bilayers embedded every other three quintuple layers (Q…
