Sulfonated polysulfone (SPSF) flat ultrafiltration membranes were successfully prepared by immersion precipitation phase inversion method. N‐Methyl pyrrolidone was used as a solvent, and polyvinylpyrrolidone (PVP) was used as a polymeric additive in the casting solution. The effects of casting solution formulation and…
Ground tyre rubber (GTR) has been employed to modify asphalt binders used in hot-mix asphalt construction since the early 1960s. Proper formulation of GTR-modified asphalt binders provides for substantial improvement in performance over conventional asphalt binders, while providing an outlet for disposal of waste tyre…
The reaction of ethanol solutions of benzoylhydrazones of 2-trifluoroacetylcycloalkanones (H 2 L) with a solution of nickel(II) acetate in aqueous ammonia in 1 : 1 ratio gave complexes NiL · NH 3 with square structure. The composition and structure of the complexes were determined by elemental analysis, IR and 1H NMR…
The synthesis and electronic properties of a series of platinum(II) complexes composed of electron-donor and electron-acceptor components as potential photovoltaic materials is reported. The complexes are composed of triphenylamines (TPA) and pyridine-derivatized TPAs as the electron-donating components, and alkynyl d…
We study angular-dependent magnetoresistance in a low-${T}_{c}$ layered cuprate ${\mathrm{Bi}}_{2.15}{\mathrm{Sr}}_{1.9}{\mathrm{CuO}}_{6+\ensuremath{\delta}}$. The low ${T}_{c}\ensuremath{\sim}4$ K allows complete suppression of superconductivity by modest magnetic fields and facilitates accurate analysis of the uppe…
PURPOSE: To test whether red blood cell (RBC) membrane composition is modified in abdominal aortic aneurysms (AAA) patients. EXPERIMENTAL DESIGN: RBC membrane extracts from AAA patients (aortic diameter >3 cm, n = 7) and control subjects (n = 4) were analyzed by a label-free quantitative MS-based strategy, using spect…
Data on the main approaches to preparation of mono- and oligodentate glycoconjugates based on porphyrin scaffolds are surveyed. The prospects for using these compounds as sensitizers for photodynamic therapy of cancer and for suppression of bacterial and viral pathogens are considered. Data on the synthesis of oligode…
Abstract Sulfonated and fluorescent polymethylsiloxanes (SO3H‐PMS) were synthesized, and their effect as additives on in vitro calcium oxalate (CaOx) crystallization was evaluated. SO3H‐PMS was prepared by hydrosilylation and sulfonation reactions with poly(dimethylsiloxane‐co‐hydrogenmethylsiloxane) (PDMS‐co‐PMHS). S…
PURPOSE: The aim of this review was to assess research methods used to determine the fracture toughness of Y-TZP ceramics in order to systematically evaluate the accuracy of each method with regard to potential influencing factors. MATERIALS AND METHODS: Six databases were searched for studies up to April 2013. The te…
Thin films of tungsten trioxide were deposited on quartz substrates by RF magnetron sputtering. Different annealing temperatures in the range from 423 to 973 K were used under ambient atmosphere. The influence of the annealing temperature on the structure and optical properties of the resulting WO3 thin films were stu…
Divalent samarium complexes SmX 2 (X = Cl, Br, OTf) have been efficiently synthesized in one electrochemical step using a sacrificial samarium anode in the presence of tetrabutylammonium salts n Bu 4 NX (X = Br, Cl, OTf) as samarium ligand sources free of any metal additives. All complexes were analyzed by electrochem…
Degradable aliphatic polyesters are the cornerstones of nanoparticle (NP)-based therapeutics. In this paradigm, covalent modification of the NP with cell-targeting motifs and dyes can aid in guiding the NP to its destination and gaining visual confirmation. Therefore, strategies to impart chemistries along the polymer…
Inorganic fillers, the second largest component of the papermaking process, have poor bondability with cellulosic fibers, interfere in interfiber bonding, and reduce paper strength. Filler preflocculation/modification is a practical method for enhancing interactions between the filler particles and fibers. This articl…
In this paper, we present a solder method for the lap joint of the YBa2Cu3O7-xcoated conductor (YBCO CC) without removing the metallic stabilizer. Several solder joints with the same overlap of 80 mm were manufactured. In the case of self-field and at liquid nitrogen temperature, the resistances of solder joints are e…
The article offers a comparison of the sensitivities for vapour trace detection of Trinitrotoluene (TNT) explosives of two different sensor systems: a chemo-mechanical sensor based on chemically modified Atomic Force Microscope (AFM) cantilevers based on Micro Electro Mechanical System (MEMS) technology with optical d…
The self-phosphorylating deoxyribozymes identified by in vitro selection can catalyze their own phosphorylation by utilizing phosphate donor guanosine-5'-triphosphate (GTP) which plays a critical role in a majority of cellular processes. On the basis of the unique properties of self-phosphorylating deoxyribozymes, we…
Exploring intracellular behavior of suicide gene is significant for improving the efficacy and safety of herpes simplex virus thymidine kinase gene/ganciclovir (HSV-TK/GCV) system in cancer therapy. Molecular imaging represents a powerful tool to understand gene transportation and function dynamics. In this work, we r…
We have studied native point defects in the layered oxides of LiNi1/3Co1/3Mn1/3O2 and Li2MnO3, the promising cathode materials for rechargeable Li-ion batteries for the application of high lithium capacity, by performing first-principles calculations. Through the calculations of formation energies for native point def…
Autolysis-assisted process mediated by indigenous protease in combination with thermal hydrolysis and hydrolysis using papain was used for production of gelatin hydrolysate from skin of unicorn leatherjacket. Prior autolysis could enhance the yield and antioxidative activity of gelatin hydrolysates, especially when su…
The present study aims to investigate the effect of two organic corrosion inhibitors, i.e. benzotriazole and adenine on the corrosion behaviour of copper and mild steel upon exposure to palm biodiesel. Static immersion tests were conducted by exposing copper and mild steel coupons to palm biodiesel (B100) in the prese…
