We present the results of spectral investigations of optical and dielectric characteristics of solid Langmuir films of meso-substituted palladium tetraphenylporphyrin. Based on these characteristics, the spectrum of the polarizability α g of the ground state of the molecule has been obtained. Necessary Lorentz correct…
The synthesis and physical-chemical characteristics of sorbents based on mesoporous silicates MCM-41 and SBA-15 with grafted sulfide functional groups are described. Similar experiments were performed on silica gels for the comparison. For the above materials, the X-ray and texture characteristics before and after fun…
Cube-like basic aluminium sulfate crystals were prepared by a facile template-free hydrothermal strategy. The microstructures, morphologies and textural properties of as-synthesized material were characterized by X-ray diffraction (XRD), field-emission scanning electron microscopy (FE-SEM) and transmission electron mi…
The paper considers the dynamic problems for piezomagnetoelectric nanodimensional bodies with account for surface stresses, surface electric charges and surface magnetic pseudocharges. For transient problem the new mathematical model is suggested, which generalize the model of the elastic medium with damping propertie…
Nanocrystalline NiO electrode is successfully electrosynthesized for supercapacitor application. The nanocrystalline NiO electrode is characterized using scanning electron microscope (SEM). Nickel oxide is a highly porous and the film surface looked smooth and composed of fine elongated particles. The supercapacitive…
Effects of cyclic straining on the development of lattice defects were studied in a medium carbon steel containing globular cementite, using thermal desorption analysis (TDA) of post-charged hydrogen that acts as a tracer. The TDA curves were statistically analyzed using Gaussian function in order to separate comprise…
The manufacturing of car interior parts with a soft touch surface is possible in a one-step injection moulding process, in which an injection moulded carrier is overmoulded with a compatible foamed thermoplastic elastomer (TPE). In contrast to the complex conventional process the structural foaming of the TPE componen…
In this paper, the Al 7003 alloy in the as-annealed condition was processed by dual equal channel lateral extrusion (DECLE) at room temperature. The microstructure and mechanical properties of the as-annealed and DECLEed alloys were examined. The results showed that the microstructure of as-annealed Al 7003 alloys was…
Fluorescence turn-off probing of Ag <sup>+</sup> in aqueous medium was realized by the utilization of a type of conjugated polymer-based nanodispersion.

Morphology-selective crystallization of manganese, nickel and iron oxides on pre-synthesized cubic cuprous oxide for photocatalysis is reported. Manganese oxide formed nanorods lying down on the surfaces of Cu2O while nickel oxide formed monodisperse nanospheres. Iron oxides formed vertically aligned nanosheets. Depos…
The paper studies the morphology, phase and elemental composition of bimetallic Al/Zn nanoparticles. It is found that metallic Al and Zn phases have interfaces within a single particle. The conversion mechanisms of Al/Zn nanoparticles in aqueous-alcoholic solutions with different water concentration are studied. It is…
Open-framework germanates are a group of germanium oxides with a well-defined porous structure, suitable for ion-exchange and gas adsorption applications. Recently, Ni incorporation into the porous structure by establishing Ge-O-Ni bonds with the molecular complexes [Ni(H2N(CH2)2NH2)2] was realized. We investigate the…
Electrochemical copper and aluminum oxidation using alternating current of industrial frequency was carried out in an aqueous sodium acetate solution. Simultaneous oxidation of metals accelerates copper oxidation, but does not significantly influence the aluminium oxidation rate. It results in the preparation of the c…
Abstract Here we review commonly used techniques for the production of large area and high quality graphene to meet the requirements of industrial applications, including epitaxial growth on SiC, chemical vapour deposition (CVD) on transition metals and growth from solid carbon source. The review makes a comparison of…
The studies of the microstructures of polycrystals produced of five varieties of wurtzitic boron nitride powders at p = 8 GPa in a range of 1600–1800°C have been considered. Particles-platelets of powders differed in size of the developed surface, thickness, and substructure. It has been found that the basic factors r…
The Seebeck coefficient S is a temperature- and material-dependent property, which linearly and causally relates the temperature difference △T between the “hot” and “cold” junctions of a thermoelectric power generator (TEC-PG) to the voltage difference △V. This phenomenon is the Seebeck effect (SE), and can be used to…
Excimer-laser-assisted metal organic deposition is a straightforward process for growing uniaxially oriented Dion–Jacobson perovskite thin films.
The ability to control the nanoscale shape of carbon nanostructures during wide-scale synthesis process is an essential goal in research for Nanotechnology applications. This paper reports a significant progress toward that goal. Variant CVD has been used for the synthesis of the samples studied. Curvature, hybridizat…
To develop the high-volume energy storage device based on ceramic capacitors, we attempted that Ti metal particles working as internal electrodes were distributed in barium titanate (BT) layers. We compared two kinds of the metal particles; uncoated Ti metal particles and Ti-BT core-shell particles (Ti metal particles…
