A further development of the method for obtaining local characteristics of multi-tip field emitter using spatial point pattern analysis was presented. The field emission characteristics of nanocomposite emitter single-walled carbon nanotubes / polystyrene were calculated. Two sets of emission sites with different curr…
An advantages of lead based ferroelectrics are a high values of polarization and adiabatic temperature changes due to electrocaloric effect. In this paper dielectric properties and electrocaloric effect in ceramics based on solid solution of lead magnesium niobate-lead zinc niobate Pb((Mg a8 Zna 2 ) 1/3 Nb 2/3 )O 3 (0…
The kinetic task about high-frequency conductivity and Hall constant of a thin conductive layer placed in the transverse stationary magnetic field and longitudinal alternative electric field is solved. The ratio between the layer thickness and the mean free path of charge carriers is supposed to be arbitrary. The skin…
One of the most important requirements for the reactor's active zone materials (made of zirconium alloys) is low hydrogen absorptivity since hydrogen embrittlement may cause zirconium cladding damage. Depending on the hydrogen content and operation temperature, hydrogen may be present in zirconium alloys as a solid so…
Most of the reported observations are about the dynamic properties of individual domain-walls in magnetic nanowires, but the properties of multiple stripe-domains have rarely been investigated. Here, we demonstrate a simple but efficient scenario for multiple domains injection in magnetic nanowires. The domain-chains…
In article number 1804321, Ying-Jie Zhu, Zheng-Dong Cai, Feng Chen, and co-workers report an enzymatic reaction strategy for the generation of biomimic nanominerals. The results provide in vitro evidence for the effect of ATP on the formation and stabilization of the biomineral, and demonstrate a potential strategy fo…
Stationary flows of viscous fluids with a static or moving contact line are considered. Contact line separates three phases: vapor, liquid and solid. No-slip condition on the solid-fluid surface and ordinary conditions with account constant surface tension for the fluid-vapor interface are supposed to be fulfilled. Th…
A Short Technical Communication on Ising Model as Mathematical Tools to Probe : CryoEM/SEM/TEM/Raman Spectroscopy/FTIR Based Images Using Python – An Interesting Insight into the Promising World of Image Processing.Though we refer to CryoEM Images it is applicable to all the images obtained through SEM/TEM/Raman Spect…
One of the promising tools for monolithic photonic integrated circuits (PICs) fabrication is focused ion beam (FIB) lithography. It's well-known that FIB etching process induces radiation defects formation and consequently leads to losses in internal quantum efficiency of luminescence. We demonstrate the possibility o…
The effect of photo-stimulated adsorption of cationic (polyethylenimine, PEI) and anionic (glucose oxidase, GOx) polyelectrolyte molecules on C-V characteristics of a electrolyte/insulator/semiconductor structure was investigated. We obtained that illumination of semiconductor during the adsorption of PEI increases a…
In the present study, the structural, optical and thermal behaviors of GeO2-PbO-CaO-SrO glasses were investigated to achieve the highest optical properties and thermal stability. Accordingly, different 50GeO2-(50-x)PbO-xCaO and 50GeO2-(50-x)PbO-xSrO (x=0, 10, 20) germanate glasses were prepared by the conventional mel…
We analytically and computationally study the generation of light in poly (methyl methacrylate) polymer optical fibres (PMMA POFs) doped with a typical coordination complex, or chelate, of Eu 3+ . The system has been modelled by means of four rate equations that describe the temporal and spatial evolution of the gener…
Periodic sequences of InAs monolayer in GaAs have been grown by molecular beam epitaxy. The properties of the structure have been modelled by transfer matrix calculation and experimentally studied by time-resolved photoluminescence. The structure obtained provides good localisation of excitons in quantum wells and ope…
Expensive immunomodulatory and antitumor drugs produced by leading pharmaceutical companies are made by chemical isolation of therapeutic polysaccharides from shiitake fruit bodies, but in doing so the biologically active complex of proteins, vitamins and minerals of the fungus is lost.The Institute of Engineering The…
L’entreprise Mécanicad se spécialise dans la fabrication des conduits de ventilation en plastique pour l’industrie minière. Certains des conduits sont fabriqués avec des brides d’attache afin de les relier entre eux dans la galerie. Le mandat de ce projet était d’étudier un procédé de déformation thermomécanique de la…
The results of the comparison of TEY and transmission methods of X-ray absorption spectra measurements as well as "thickness effect" modeling in the linear absorption coefficient spectral dependences of the C 60 -films in the NEXAFS C1s-spectra are represented. The calculations were performed with using linear absorpt…
In this paper, we report the development of a novel technique in which the magnetoresistance of nanostructures is perturbatively measured by transversally modulating the DC magnetic field. It measures the electrical transport counterpart of the transverse magnetic AC-susceptibility. The technique was developed in a co…
X-ray studies of binary vanadium-containing catalysts were carried out. The results of the investigations showed that in the W-V-O system three phases are formed, two modifications of WO 3 and one V 2 O 5 . Based on the analysis of diffraction patterns, it was found that in all samples of the Sn-V-O system are observe…
Abstract Removal of oil and organic pollutants from water is desired due to the frequent oil spill accidents and increase of industrial oily wastewater. The development of absorbent materials with high absorption capacity for separation and removal of oils from water should be of great importance to address environmen…
In this work, we analyze the length distributions of self-catalyzed GaAs nanowires grown on in-situ processed SiOx/Si(111) substrates. We propose the model that accounts for (i) gradual emerging of Ga droplets and nanowires, (ii) fluctuation-induced broadening of the length distributions, and (iii) the effect of nucle…
