We demonstrate current oscillation phenomena using the negative differential resistance in a one-dimensional halogen-bridged nickel compound, [Ni(chxn)2Br]Br2 (chxn=cyclohexanediamine). By attaching external resistors and a capacitor to a [Ni(chxn)2Br]Br2 sample, we obtain stable current oscillation at 90 K. The oscil…
Mn-doped SrTiO 3 samples (3% Mn) with different deviations from stoichiometry have been investigated using XAFS spectroscopy. It was shown the under various preparation conditions manganese atoms can sub-stitute A and B sites of the perovskite structure and are in them in different charge states. Impurity Mn 4+ ions t…
The influence of benzotriazole on electrochemical behavior of copper in borax buffer solutions, in pH range 8.0-12.3, with or without 0.05 M NaCl chlorides, was studied. Two methods were used in order to examine the effect of BTA: a) the Cu electrode was immersed for various time periods (5, 15 and 60 min) in 0.2 % BT…
Antibacterial packaging is gaining a lot of importance in the food industry. Plastics such as polypropylene, polyethylene, polyamides, polyethylene terephthalate, polyvinylidene chloride copolymers, etc., and paper, paperboard, and aluminum foils have been used as food-packaging materials. In the past, aluminum foil h…
We propose stable layered structures and ultrathin tubular configurations of titanium oxide (TiO 2 ) nanomaterials on the basis of first-principles calculations within density functional theory. The thinnest TiO 2 nanosheet is characterized by a reconstructed (001) bilayer of rutile TiO 2, while ultrathin TiO 2 nanotu…
Abstract Rectification properties of Au Schottky diodes were investigated in high‐temperature operation. These diodes were fabricated on a p‐type diamond single crystal using the vacuum‐ultraviolet light/ozone treatment. The ideality factor n of the Schottky diodes decreased monotonically with increasing measurement t…
Controllable modification of surface free energy and related properties (wettability, hygroscopicity, agglomeration, etc.) of powders allows both understanding of fine physical mechanism acting on nanoparticle surfaces and improvement of their key characteristics in a number of nanotechnology applications. In this wor…
The interest in biofibers has grown in recent years due to their expanding range of applications in fields as diverse as biomedical science and the automotive industry. Their low production costs, biodegradability, physical properties, and perceived eco-friendliness allow for their extensive use as composite component…
The influence of Sn doping on the growth of In2O3 on Y-stabilized ZrO2(100) by oxygen plasma assisted molecular beam epitaxy has been investigated over a range of substrate temperatures between 650 and 900 °C. The extent of dopant incorporation under a constant Sn flux decreases monotonically with increasing substrate…
The design elements of intelligent clothing were studied in this research. Both garment design as well as knitting technology concepts were applied to wearable electronic garments with aesthetic, functional, and technical features. In addition, a new garment design method is proposed for a specific task based on combi…
Columnar liquid-crystalline (LC) truxene derivatives containing branched flexible alkyl chains have been designed and synthesized. The dicyanomethylene and dithiafulvene substituents have been introduced into the pi-conjugated truxene framework to tune their electronic and redox properties as well as the molecular ass…
Lithium borohydride has a high reversible hydrogen storage capacity. For its practical use as an on-board hydrogen storage medium in mobile applications, the temperature and pressure conditions along with the kinetics of the hydrogenation/dehydrogenation cycles have to be improved. Lithium borohydride can be modified…
A series of ZnSe single layers having thickness between 30 nm and 1 m was deposited on c-Si and glass substrates at room substrate temperature. Thermal evaporation of ZnSe powder in high vacuum has been applied. Moreover, SiO x /ZnSe periodic multilayers prepared by the same deposition technique and having ZnSe layer…
Abstract Direct experimental evidence for the existence of a 2D electron gas in devices based on ZnO nanowires (NWs) is presented. A two‐channel core/shell model is proposed for the interpretation of the temperature‐dependent current–voltage ( I – V ) characteristics of the ZnO NW, where a mixed metallic–semiconductin…
The possibility of producing the ferroelectric state in nanoporous aluminum oxide loaded with triglycine sulfate and Rochelle salt has been studied. Our dielectric, pyroelectric and emission measurements give grounds to suggest that this state persists in the composites under study up to temperatures exceeding the Cur…
In recent years it has become clear that complex oxides provide an exceptional platform for the discovery of new physics as well as a considerable challenge to our understanding of correlated electrons. The tendency of these materials to display nanoscale electronic and magnetic inhomogeneity is a good example. Here,…
This article is a review of present-day methods of the formation of the structure of various metalasiloxanes (MS’s). Methods of designing the structure of catalytically active MS’s are discussed. In the description of synthetic methods and catalytic properties, the MS’s are divided into two groups, namely, individual…
Pure and hybrid exchange-correlation functionals, as typified by OLYP and B3LYP, respectively, yield dramatically different spin density profiles for a variety of paramagnetic iron nitrosyls. Not unexpectedly, based on the strongly noninnocent nature of the NO ligand, the strength of metal-NO spin coupling appears to…
LOCA-simulated experiments were performed with MDA, ZIRLO™, M5®, NDA, and Zircaloy-2 cladding specimens with local burn-ups ranging from 66 to 76 MWd/kg. Short test rods fabricated with the cladding specimens were heated, isothermally oxidized at 1,459 to 1,480K in steam flow, and finally quenched in flooding water. R…
This work focuses on the dynamic properties and energetics of the protein/peptide drug during its transport through carbon nanotubes (CNTs). A systematic study was performed on the interaction between the peptide and the CNTs. In the molecular dynamics (MD) simulations, the protein/peptide molecule Zadaxin is observed…
