The hydrotalcite-like compound [Zn 2 Al(OH) 6 ]NO 3 mH 2 O (shorted as ZnAl-NO 3 ) was intercalated with the chelating agent EDTA (ethylene diamine tetraacetic acid) by anion exchange to uptake cadmium ion from aqueous solutions. The materials synthesized in this work were characterized by chemical analysis, FT-IR (fo…
С помощью методов математического моделирования оценивали влияние технологических параметров электронно-лучевой плавки на содержание легирующих элементов в слитке титанового сплава ВТ19, а также адекватность построенной математической модели для многокомпонентных титановых сплавов. На основании расчетов определены опт…
This study aimed to develop an optimal sizing system and a draping pattern for hip protector based on an analysis of anthropometric characteristics of Korean older women. A hip protector is a specialized form of pants or underwear containing pads along the outside of each hip. The 3D body scan data of Korean older wom…

As a type of accident-tolerant fuel, fully ceramic microencapsulated (FCM) fuel was proposed after the Fukushima accident in Japan. The FCM fuel consists of tristructural isotropic particles randomly dispersed in a silicon carbide (SiC) matrix. For a fuel element with such high heterogeneity, we have proposed a two-te…
Dihydrodipicolinate reductase is an enzyme that converts dihydrodipicolinate to tetrahydrodipicolinate using an NAD(P)H cofactor in L-lysine biosynthesis. To increase the understanding of the molecular mechanisms of lysine biosynthesis, we determined the crystal structure of dihydrodipicolinate reductase from Coryneba…
This review is focused on the use of the water splitting reaction for characterizing oxygen vacancies in supported metal catalysts and more generally to get insight into the high-temperature modifications of metal–support interactions. Three supports widely used in catalysis are considered, namely alumina, silica and…
In this study, we present a new process of developing silver nanoparticles (AgNPs), using intercalated clay (saponite)/poly acrylamide (PAAm) nanocomposite (NC) hydrogels, via the reduction of silver ions with NaBH 4 in aqueous solutions. The –NPs obtained are very stable at room temperature due to the extended coil c…
Stress-driven grain boundary motion is one of the main mechanisms responsible for microstructural evolution in polycrystalline metals during deformation. In this research, the interaction of shear-coupled grain boundary motion (SCGBM) in face-centered cubic metals with crack, which is a common type of structural defec…
Temporal evolution and spatial distribution of acoustic cavitation structures in a thin liquid layer were investigated experimentally with high-speed photography. The inception and disappearance processes of cavitation bubble cloud revealed that the metastable cavitaton structures formed in the thin liquid layer cause…
The microstructural stability in three as-extruded Mg alloys (Mg–0.6Ca, Mg–1.9Sn and Mg–1.9Sn–0.6Ca) at high temperature (673 K) is studied by optical microscope (OM), scanning electron microscopy (SEM), and its effect on the mechanical properties is tested by tensile test. The grain size of Mg–1.9Sn–0.6Ca alloy is re…
Silk cocoon is composed of multiple layers. The natural silk cocoon containing all layers was cut as a rectangular shape as defined as total group. The inner and outermost layers were removed from the total group and the remained mat was defined as the middle group. The objectives of this study was to compare the tota…
Attapulgite (ATT) is a one‐dimensional (1D) nanorod which shows great potential as an effective filler for enhancing polymers. However, natural ATT is hard to develop its nanoscale reinforce advantages because it always tend to aggregate in the matrix. In this work, hybrid filler composed of ATT nanorods attached on t…
Previous work has shown that a low level of sulphate impurity in chromic acid can significantly change the growth rate and the morphology of porous anodic films formed on aluminium at a constant voltage. The changes were associated with incorporation of sulphate into the films. The present study employs electron micro…
Polyaniline–Nd2O3:Al2O3 nanocomposites were prepared by in situ oxidative polymerization method using different weight percentages of oxide powders. The prepared nanocomposites were characterized by Fourier transform infrared spectroscopy and X-ray diffraction for molecular and crystal structures. Scanning electron mi…
Tricine can be considered as effective corrosion inhibitor for the corrosion of zinc in neutral chloride solutions. • The studied Tricine compound ( N -( Tri ( hydroxymethyl ) methyl ) glycine ) acts as efficient corrosion inhibitor. • Electrochemical techniques were used to evaluate Tricine as corrosion inhibitors. •…
UNLABELLED: Complex formation and conformational transitions of biological macromolecules in solution can be effectively studied using the information about overall shape and size provided by small angle X-ray scattering (SAXS). Hybrid modeling is often applied to integrate high-resolution models into SAXS data analys…
Purpose To develop and optimize a multislice glycosaminoglycan (GAG) chemical exchange saturation transfer (GagCEST) sequence for volumetric imaging of articular cartilage, and to validate the sequence against T 1ρ relaxation times in whole joint imaging of tibiotalar cartilage. Methods Ex vivo experiments were used t…
Liquid crystals (LCs) display many of the flow characteristics of liquids but exhibit long range orientational order. In the nematic phase, the coupling of structure and flow leads to complex hydrodynamic effects that remain to be fully elucidated. Here, we consider the hydrodynamics of a nematic LC in a hybrid cell,…
Highly crystalline zinc oxide (ZnO) nanowires (NWs) were synthesized through chemical bath deposition (CBD) method by using a simple seeding technique.
