The solubilities of the sulfonamide—sulfamethoxazole in methanol, ethanol, 1-propanol, 2-propanol, and chloroform have been determined at 293.15–323.15 K by a static equilibrium method. The experimental results can be approximated with Apelblat equation. The positive enthalpy Δsol H and entropy Δsol S for each system…
This review introduced the preparation and structural characterization of polyelectrolyte multilayers in recent years and also summarized the tribology research progress of the polyelectrolyte multilayers, including tribological properties, surface adhesion characteristics, and wear resistance properties. Statistics a…
Cu-W thin films were electrodeposited on indium tin oxide (ITO) glass substrates in an aqueous solution using a rectangular pulse current technique in a range of frequency from 0.2 MHz to 1 MHz. The W concentration in the Cu-W thin film measured with energy dispersive X-ray spectroscopy (EDX) was dependent on an ampli…
We analyze the effect of magnetic fluctuations in superconductors with strong spin-orbit coupling and show that they drive a phase transition between two superconducting states: a conventional phase with zero center-of-mass momentum of Cooper pairs, and an exotic phase with nonzero pair momentum. The latter is found t…
A upconversion nanocrystal of NaYF4:Yb/Tm was synthesized successfully by two different methods of solvothermal and hydrothermal, respectively. The properties of the products were characterized and compared. The results showed that the nanocrystal prepared by hydrothermal method exhibited uniform hexagonal phase and l…
Laser techniques such as pulsed laser deposition, combinatorial pulsed laser deposition, and matrix-assisted pulsed laser evaporation were used to deposit thin films for optoelectronic applications. High-quality transparent conductor oxide films ITO, AZO, and IZO were deposited on polyethylene terephthalate by PLD, an…
There are non‐linear behaviours in superconductive circuits such as superconducting metamaterial filter. In this study, the authors propose a distributed non‐linear equivalent circuit model for the superconducting metamaterial filter based on the stepped impedance resonator. This model can be used to predict the non‐l…
Using of cutting inserts is currently a normal part of the manufacturing process. The article deals with the tool wear evaluation of selected inserts for turning by electron microscopy. Use of electron microscopy helps closer analysis of machining consequences for these plates, because the microscope images captured w…
Notice of redundant publication "Micron-scale Raman amplifier: another progressive step towards the maturity of silicon photonics" It has been brought to the attention of the editors that this article contains redundancies when compared with an earlier article published by the authors in Datta T and Sen M 2017 Superla…
A near single-variant martensitic state of Co[Formula: see text]Ni[Formula: see text]Ga[Formula: see text] alloy was induced by a static axial stress of 66[Formula: see text]MPa. Upon application of a magnetic field pulse, the single-variant state of stressed specimen was transformed into a hierarchic martensitic stru…
Industrial waste stocks in Kazakhstan significantly increase and only 10-15 % of total generated industrial waste is utilized. Industrial waste dumps occupy large areas, have negative impact on the environment and degradation of landscape. Sustainable waste management strategy leads to waste recycling and development…
By using the Bergman representative coordinates, we give the necessary and sufficient condition for the degree of automorphisms of quasi-circular domains fixing the origin to be bounded by the resonance order, thus solving a conjecture of the author.
Abstract A series of organic-inorganic composite catalysts were prepared by modifying tungstophosphoric acid (H 3 PW 12 O 40 ) and propyl sulfonic acid-functionalized ionic complex. The obtained water-soluble catalysts were well characterized by Fourier transform infrared spectroscopy, X-ray diffraction, thermogravime…
The objective of this paper is to develop a mechanism-based theoretical model to explain fracture experiments conducted on nanographene platelet (NGP) reinforced thermoset polymer nanocomposite tested in pure Mode I and in mixed mode by the authors and other researchers. Remarkable improvement in fracture toughness, K…
Intravascular leiomyomatosis (IVL) is a benign smooth muscle tumor that evolves from the pelvic veins and can spread to the central veins and heart. Cardiac involvement is the most commonly reported presentation. Initial diagnosis is difficult, and IVL is commonly misdiagnosed as thrombus or atrial myxoma. Appropriate…
The rule that governs surface reactions provides very important information for fundamental studies in chemistry and biochemistry. The potential to define the chemical and physical properties of solid surfaces is decisive for chemical sensing, electronics and many other applications. The application of the technique i…
We presents a novel approach for in situ growth of highly-dispersed gold nanoparticles (AuNPs) on the electropolymerized methylene blue (PMB)/ITO electrode (Au/PMB/ITO) without using additional binding molecules and toxic reductants. Methylene blue (MB) monomers remaining in the PMB films on ITO served as both the red…
We revisit the classical problem of the molecular orientation inside a hybrid cell filled with liquid-crystals with various elastic constant anisotropies by means of Monte Carlo simulations using the Gruhn-Hess effective pair potential. We find some unstable defect lines and we discuss their arising in the system. We…
The possibility to determine the thermal conductivity of construction materials outside the laboratory conditions is useful for professional practice mainly for control and inspection activities on real existing buildings. This paper describes the method and results of measurements focused on different natural thermal…
In recent years human activities have influenced a significant increase in the amount of waste lubricants (WL). Annually the minimum number of waste lubricating materials in Russia amounts to 500 thousand tons, out of it only 14-15 % are reprocessed, the rest is illegally dumped into the soil or waterways. Environment…
