The electronic spectra and magnetic properties of rutile (TiO2), nonstoichiometric rutile (TiO2 − δ), and stoichiometric and nonstoichiometric rutiles doped with carbon or nitrogen (TiO2 − y − δC y and TiO2 − y − δN y , y(δ) = 0, 0.03, 0.06) have been calculated using the coherent potential method. The used method of…
Material design and synthesis are key steps in the development of catalysts. They are usually based on an empiric and/or theoretical approach. The recently developed high-throughput experimentation can accelerate optimisation of new catalytic formulations by systematic screening in a predefined study domain. This work…
Multiphoton microscopy is a valuable technique for producing high-resolution images deep within intact biological tissue in vivo. Furthermore, multiphoton microscopes that utilize longer-wavelength excitation at ∼1700 nm as well as higher-order excitation processes permit deeper imaging within the same tissue [1]. We…
We studied the effect of reinforcing phases introduced into the melt ex situ and formed directly in situ during mechanical activation of powders or mechanical mixing in the melt on the structure and mechanical and tribological properties of aluminum-matrix cast and aluminum-powder composites. Intermetallic inclusions,…
The main elements of the composition-structure-properties relationship are considered for radiation-resistant deactivatable protective organosilicate coatings in the system polyorganosiloxanes-layered hydrosilicates-metal oxides and salts. Examples of radiation-resistant protective coatings are given. It is pointed ou…
Fluoropolymer thin films were prepared by the ion-assisted vapor deposition polymerization (IAD) of 2-(perfluorohexyl) ethylacrylate (Rf-6) under Ar ion irradiation. The ion acceleration voltage V a largely affected the film characteristics. With increasing V a , the adhesion strength between the film and the substrat…
Metrological assurance has been developed and formed for a promising technique for measuring the mass fraction and number concentration of nanoparticles containing silver or zinc in different media, including those of a biological nature, i.e., the gamma-ray spectroscopy of neutron-activated samples along with dynamic…
A thin hollow elastoplastic or perfectly plastic disk placed in a rigid cylindrical container and subjected to the action of a temperature field is considered. The conditions of plane stress state are assumed. The Mises yield condition is satisfied in the plastic zone. The main feature of the problem formulation is in…
We show that Sm 10 Co 90 amorphous films exhibit anisotropic magnetostriction effects when a magnetic field is applied perpendicular to the imprinted easy axis of magnetization. At low applied fields (0–100 mT), we observe strong anisotropy in the field response. Parallel to the applied field, the strain scales linear…
(FeIn2S4)1 − x (In2S3) x alloy single crystals are grown by oriented crystallization in the entire range of component concentrations. For the single crystals, studies of the magnetic properties are carried out in the temperature range 4–300 K and the magnetic-field range 0–14 T. It is established that almost all of th…
Au core-Ag shell nanoparticles (NPs) have been grown on the silicon substrate with self-assembled well-define Au NPs by electroless plating method. The holding time of spin-coating strategy is a facile method for controlling the densities of Au NPs and treating them as an electrode for selective growth of Ag shell. Th…
A new kind of Schiff base, 4-((4-dodecylphenylimino)methyl)phenol (DPMP), is synthesized. Its structure is characterized by Fourier-transform infrared (FT-IR) and 1H nuclear magnetic resonance. Self-assembled films of DPMP are prepared on a copper surface. Electrochemical impedance spectroscopy (EIS) and polarization…
The effects of ultrasonic vibration solidification treatment (UVST) on the corrosion behavior of AZ80 magnesium alloy have been investigated by means of microscopy observations and electrochemical measurements. The results show that the UVST process improves the corrosion resistance of AZ80 alloy. The electrochemical…
ZnO nanoparticles-embedded hydrogenated diamond-like carbon (ZnO-DLC) films have been prepared by electrochemical deposition in ambient conditions. The morphology, composition, and microstructure of the films have been investigated. The results show that the resultant films are hydrogenated diamond-like carbon films e…
In the present study we report the influence of variation in amount of Zn on growth and optical properties of thin films of ZnO nanocrystals in silica matrix deposited by rf magnetron co-sputtering with substrate heating at 200 o C. RBS studies indicate change in the concentration of Zn in the films while Raman spectr…
Properties of nanoparticles are significantly different from their bulk counterparts, including their biological and toxic activity. The properties of silver nanoparticles governing their toxicological effects are summarized. These basic characteristics can be used as descriptors for modelling the toxic properties of…
Equal channel angular pressing (ECAP) in magnesium alloys due to severe plastic shear deformations provides both grain refinement and the slope of the initial basal texture at 40°–50° to the pressing direction. These changes in microstructure and texture contribute to the improvement of low-temperature plasticity of t…
The epoxidation of syndiotactic 1,2-polybutadiene (84 and 16% 1,2 and 1,4 units, respectively) with carboxylic peracids prepared in situ and m -chloroperbenzoic acid was studied. In the course of epoxidation in the presence of carboxylic peracids, oxirane groups are formed only through epoxidation of double bonds in t…
While an Hourly Price Forward Curve (HPFC) plays a defining role in the profitability of all power trading, there is a lack of consensus on the a priori requirements of a suitable HPFC, as opposed to the a posteriori quality measure that executed trades be profitable. We attempt to address this issue by reviewing the…
Chalcogenide glasses are interesting materials on account of their infrared application. In present paper, thin films of quaternary chalcogenide glasses, Se80.5Bi1.5Te18 − x Sb x , where x = 0, 2, 4, has been investigated for their optical properties using transmission spectra in the spectral range of 500–2500 nm.
