This paper describes the features of new membranes that can act as local biomedical devices owing to their peculiar shape in the form of mesh structure. These materials are designed to provide significant effects to reduce local inflammations and improve the tissue regeneration. Lamellar Hydrotalcite loaded with Diclo…
A method of calculation of multidimensional space of coatings formed from flat panels is described. Differential equations of equilibrium and deformations of shells with discontinuous parameters are given. The comparison of the calculation results envelope defined by the proposed method and by FEM is done. Ill. 2, bib…
BiFeO3-based nanopowders were prepared via a sol-gel method, in which the gel (with metal-nitrate, maleic acid and water used as raw materials) was sintered at 650°C for 2 hours. The aggregation of nanopowders was destroyed by high energy ball milling for 12 hours. BiFeO3-based nanoceramics were prepared by spark plas…

We designed complex phase-matching spectral grid by iterative domino algorithm, and analytically proved that it can achieve the maximum conversion efficiency. Experimentally measured conversion efficiencies agreed well with the numerical results.
There are some problems in the permanent magnetic circuit of the current permanent magnet biased magnetic bearings, such as small magnetic force, low magnetic flux density and lack of self-stabilization. To solve this problem, a new hybrid radial magnetic bearing structure has been proposed. The nonlinear model and li…
We investigate the electronic structure of a boride superconductor, ZrB12 employing high resolution photoemission spectroscopy and ab initio band structure calculations. Sharp B 1s and Zr 3d core level spectra with distinct signature of the satellites exhibits good quality of the sample. The band structure results ind…
A near-infrared wide-band polarization-insensitive absorber is demonstrated. It is composed of two-dimensional titanium disk arrays and a gold plate. The absorption at normal incidence is above 90% in the range of 164.2THz to 345.2 THz.
The electrical conductivity of graphite dispersions in potassium chloride (KCl) solutions in the alternating (1000 Hz) and constant electric field has been measured. In the alternating electric field (0.0005 - 0.01 М KCI) the electrical conductivity increases depending on the mass fraction of the dispersed phase. In t…
A dual-core spot size converter (DC-SSC) is integrated with a lateral grating assisted lateral co-directional coupler (LGLC) tunable laser by using no additional complicated fabrication processes. The excess loss due to the DC-SSC is only 0.5dB, and narrow full width half maximums (FWHMs) of vertical and horizontal fa…
Оne of the chemical methods of receiving an ultradisperse powder of cobalt by reduction of crystal salt of cobalt carbonate with hydrazine water solution is considered in the paper. Particles of the various sizes and forms have been received. The temperature and concentration factors influencing dimensional characteri…
Penetration of concrete targets was simulated based on self-compiled program generating two-dimensional random aggregate model. Random convex polygons were used to simulate the aggregate particles of concrete, HJC model to describe constitutive relations of the aggregates and mortar while concrete targets are subjecte…

In an alkaline methanol solution, dimerization of 1-phenyl-1H-tetrazole-5-thiol (HL) was carried out over metalloporphyrin catalysts under mild conditions. The dimer product, 1,2-bis (1-phenyl-1H-tetrazol-5-yl) disulfane (L-L), was characterized by determinations of infrared (IR), HPLC, NMR and elementary analysis res…
Antireflective structures were fabricated on fluorescent 6H-SiC for white LEDs to enhance the extraction efficiency. Average surface reflectance decreased from 22.1 % to 5.1 % over a broad range, and luminescence intensity was enhanced by 41 %.
A fast numerical method for the calculation in a zero-dimensional approach of the equilibrium isotopic composition of an iteratively used transmutation system in an advanced fuel cycle, based on the Banach fixed point theorem, is described in this paper. The method divides the fuel cycle in successive stages: fuel fab…
The Fe-Cu system in bilayer and alloy form was prepared using a D.C. magnetron sputtering system fabricated in-house, and studied by several techniques. Structural characterization of the samples was performed by X-ray and polarized neutron reflectivity and time-of-flight secondary ion mass spectrometry. SQUID magneto…
A framework to determine interfacial structure, temperature, and photovoltage dynamics based on surface sensitive ultrafast electron crystallography and voltammetry is demonstrated based on recent studies of surface supported nanomaterials.

Oxidative stabilities of single component nanoclusters are studied in the presence of an oxophilic element. Atomistic simulations are used to study the early stages of heterogeneous oxidation of a representative binary alloy nanoclusters such as Ni–Al. The role of oxophilic Al atoms in enhancing the oxidation of Ni at…
