The X-ray and magnetometry methods were used to study α-γ transformation mechanisms on heating quenched Fe-22.7 wt.% Ni-0.58 wt.% С alloy. Variation of heating rate within 0.03-80 K/min allowed one to switch from diffusive to non-diffusive mechanism of the α-γ transformation. Heating up primary austenitic single cryst…
In order to investigate the magnetic abnormality influenced by stress in weld seams, experiments on three types of weld seams were carried out and a stress concentration detection instrument - metal magnetic memory (MMM) tester was used. MMM tests on gas pipelines in Puguang initial station in China were conducted and…
18-8 stainless steel is one of the most versatile materials. Some of its uses are related to structural applications; in this case, the high mechanical properties required are obtained by controlled lamination after re-crystallisation annealing. In this work, detailed analyses by FEG-SEM and EBSD have been done to cor…
This review describes the application of different nanostructured materials in solar cells technology for improvement of sun-light harvesting and their efficiency. Several approaches have recently been proposed to increase the efficiency of solar cells above the theoretical limit which are based on a "photon managemen…
Chrysoberyl is one of the most interesting minerals for laser applications, widely used for medical purposes, as it exhibits higher laser performance than other materials. Although its utilization has been vastly expanded, the location of transition metal impurities, especially the iron that is responsible for chrysob…
Abstract Here, we present a novel method of growing protein crystals with nanofibers. Protein crystals were grown by incorporating nanofibers. No obvious differences were observed in diffraction data between fiber-containing and as-grown crystals. The fiber-containing crystals displayed an increased tolerance to osmot…
Direct correlation functions (DCFs) play a pivotal role in modern liquid-state theories and are virtually indispensable for non-mean-field implementation of the classical density functional theory (cDFT). Whereas analytical expressions have been derived for the DCFs of simple fluids and electrolytes, DCFs for molecula…
On the basis of the recently synthesized cyclo-1,4-phenylene-2′,5′-thienylenes ([ n ]CPTs) (Ito et al. Angew. Chem. Int. Ed. 2015, 54, 159–163), a set of nanoporous molecular crystals were designed, and the adsorption properties were investigated by means of Grand canonical Monte Carlo simulations, in which the force…
Abstract Fine features of the crystal structure of Zn0.9Ni0.1S, Zn0.9V0.1Se, Zn0.95Fe0.05Se semiconductor cubic single crystals have been characterized by neutron scattering at room temperature. It has been revealed that neutron‐diffraction scans of the single crystals, in addition to intense Bragg reflections of face…

Abstract Objective: Tissue integration of vascular grafts partially depends on the host response to injury, which immediately begins after implantation and restoration of the circulation. In an infected environment, the inflammation changes the incorporation patterns. The aim of the study was to observe the tissue inc…
The dipole moments of the ground and excited states of 4′-(hexyloxy)-4-biphenylcarbonitrile and 4-isothiocyanatophenyl 4-pentylbicyclo [2.2.2] octane-1-carboxylate nematic liquid crystals and their mixtures prepared in chloroform and dichloromethane were studied at room temperature. The dipole moments of the ground st…
The preparation of pure lithium niobate nanopowders was carried out by a matrix-mediated synthesis approach. Lithium hydroxide and niobium pentachloride were used as precursors. The influence of the chemical environment was studied by adding lithium halide (LiCl or LiBr). After thermal treatment of the precursor mixtu…
The relatively simple peptides assembled on the templates are excellent mimic of complex conformational and functional defined binding sites of proteins. The main benefit of experiments with artificial receptors arises from the relative simplicity of the interacting host-guest system allowing the understanding of the…
Zinc germanium diphosphide (ZnGeP2) is an attractive and promising functional material for different devices of the nano- and optoelectronics. In this paper, dispersion of phonon surface polaritons (PSPs) in ZnGeP2 has been studied in the 200-500-cm(-1) spectral range at 4 and 300 K. Dispersion of "real" and "virtual"…
Four algal specimens with morphological resemblance to Audouinella were collected in China, both bluish and reddish thalli included. Because of the taxonomic obscurity of the acrochaetioid lineage, a molecular phylogenetic analysis was performed to verify the phylogenetic position of these specimens based on three sho…
Abstract The paper presents results of the study of two narrow luminescence lines I1 and I2 at the energies of 3.339 and 3.393 eV respectively in solid state solutions Zn1‐xNixO. The luminescence spectroscopy with a sub‐nanosecond time resolution upon selective photoexcitation in the energy range of the inner shell Zn…
We prepared an asymmetric liquid crystal dimer possessing a terminal hydroxyl group, 2-{4-{7-[4-(4-cyanophenyl)phenyloxy]heptyloxy}phenyl}-5-(6-hydroxyhexyloxy)pyrimidine, and investigated the phase transition behaviour using polarising optical microscopy and differential scanning calorimetry. The compound exhibited a…
Biology uses dynamical mechanisms of self-organization and self-assembly of materials, but it also choreographs and directs these processes. The difference between abiotic self-assembly and a biological process is rather like the difference between setting up and running an experiment to make a material remotely compa…
Surface-functionalized carbon nanotubes (CNTs) are introduced into lithium-doped ZnO thin-film transistors (TFTs) as an alternative to the conventional incorporation of an expensive element, indium. The crucial role of surface functionalization of CNTs is clarified with the demonstration of indium-free ZnO-based TFTs…
