New vitamin B12 derivatives activates sGC
Background Protoporphyrin IX (PPIX) was shown to strongly activate in vitro the soluble guanylate cyclase enzyme (sGC), which makes it an interesting drug candidate for treatment of hypertension [1,2]. In order to overcome the problem of PPIX poor bioavailability (especially in the case of oral administration), we dec…
Preparation of titanium nanopowder by induction plasma technology
The spherical titanium nanopowder is prepared by induction plasma technology, according to scanning electron microscope, oxygen-azote mensuration equipment and inductive coupled plasma emission spectrometer, the morphology and chemical constitution of titanium nanopowder are characterized. With the processing paramete…
Effects of oxygen stoichiometry on the photovoltaic properties of La0.4Ca0.6MnO3-δ epitaxial films grown on miscut MgO substrates
We report the effects of lattice constants variation induced by oxygen stoichiometry on the photoresponse properties of La0.4Ca0.6MnO3-δepitaxial films grown on miscut MgO substrates. The oxygen content was changed by annealing the sample in oxygen and vacuum. With the decreases of oxygen deficiencies, the electrical…
Preparation, Spectral Characterization and Fluorescence Property of Schiffbase Mg(II) Complex Material
The reaction of 1-(1-hydroxy-2-naphthalenyl)-N, N-bis(3-aminopropyl)methylamine with MgCl2•6H2O in CH3CH2OH followed by recrystallization in CH3CH2OH gave rise to colorless block Mg (II) complex crystal material. The Mg (II) complex has been characterized by elemental analysis, IR spectra and molar conductivity. The p…

Antenna design using Transformation Electromagnetics (TEM)
We present two different points of approaches to a class of antenna designs, based on two variations of the Transformation Electromagnetics (T-EM) approach, both of which have been introduced recently in the literature. The first of these addresses the antenna and absorber design problems from the Transformation Optic…
Constraints on the temporal dispersion of passive metamaterials
Metamaterial applications such as cloaking, perfect lenses, and artificial permeability are restricted by the frequency dependence of the permittivity, permeability, and index of refraction. Here, causality and passivity together with integral identities for Herglotz functions are used to construct sum rules. The sum…
Stepped leader characteristics in developing horizontally within thunderclouds and in descending out of thunderclouds
We examine VHF and optical images of cloud-to-ground flashes to study IC leaders that propagated within thunderclouds and CG leaders that descended outside thunderclouds. It is shown that IC leaders developed smoothly and CG leaders propagated in a heavily branched manner. We speculate that, in the case of IC leaders,…
The ESR characters of unintentionally doped 4H-SiC with Si ion implanted
The intrinsic defects in epitaxial semi-insulating 4H-SiC that are implanted by Si ion, annealing after implanted respectively are studied by electron spin resonance (ESR). The results show that the intrinsic defects in Si ion implanted and annealing are the same as that as-grown 4H-SiC consist of carbon vacancy (Vc)…
Computational electromagnetic solutions for large-scale conductors, left-handed metamaterials and plasmonic nanostructures
We present some integral-equation approaches for the accurate solution of different problems in computational electromagnetics. First, an efficient MPI/OpenMP parallel implementation of MLFMA-FFT algorithm is presented for the solution of large-scale metallic conducting bodies. By combining the high scalability of FMM…
Computer Simulation of Variation Features of Double-Deck Rectangle Phase Grating
The variation features of double-deck rectangle phase grating were theoretically investigated, and the conditions for split of two bunches of light, three bunches of light and four bunches of light were discussed. By computer simulation, optimal parameters were put forward.
Effect of magnetic impurities in based on shungite electromagnetic absorbers on its shielding properties
The effect of ferromagnetic impurities in electromagnetic based shungite absorbers is studied. The presence of the particles magnetic powder in composite structure influences on attenuation and reflection characteristics of shielding material has been established. It is found that exact quantity of magnetic inclusions…
Intercalation effect on the optical properties, structure, and chemical composition of thin film systems
The effect of gaseous ammonia intercalation (IC) on the optical and structural properties of two-layer Ag-PbI2 systems and PbI2 films, both freshly prepared and irradiated by laser beams with wavelengths λ a = 442 nm and λ0 = 633 nm, is studied. The changes in the spectra of optical transmittance are shown to be cause…

AN INSIGHT INTO FIBER–SOLVENT MEDIATED MODULATION OF NANO-FIBRILLAR ORGANOGELS
The effect of gelation and the modulation of their properties with the variation of aliphatic hydrocarbon solvents, e.g., n-decane and n-dodecane have been presented for a homologous series of amides of L-alanine with fatty acids. The gelation properties of these compounds were studied by a number of physical methods…
Design, application and maintenance of HTR-10 full digital safety I&C system
The safety instrumentation and control (I&C) system of the 10MW High Temperature Gas-cooled Reactor (HTR-10) is the key system referred to the safety of the reactor. It is designed based on the advanced digital control techniques. This article introduced its architecture, configuration, design feature and engineering…
Superplastic forming of AZ31 magnesium alloy using resistance heating
Superplastic forming using resistance heating (SPFRH) is developed to solve the problems of high energy consumption and low efficiency. In this process, the sheet is connected in series with a high current circuit and heated directly by the electrical resistance. The heating rate of the sheet is controlled by current…
Self-aligned nanowires in tetrahedral amorphous carbon multilayer structures
In this work we combine ion track techniques to construct self-aligned vertical structures with nanometer dimensions. The main idea is to use multilayer targets and apply various etching techniques to create openings along the ion path. By irradiating such a multilayered sample including a tetrahedral amorphous carbon…
Nonlinear photonics of backward waves
Several nonlinear-optical coupling schemes in double domain positive/negative index metamaterials are proposed, which include ordinary and backward electromagnetic waves. One of them is investigated in the context of the applications to compensating strong losses inherent to plasmonic metamaterials and to design of no…
