This paper reports the development of an electronic temperature sensing (ETS) yarn by embedding commercially available thermistors within the fibres of a yarn. The thermistor is initially soldered onto a fine copper wire and then encapsulated to form a polymer micro-pod. The micro-pod protects the thermistor from mech…
This paper discussed on the preparation of natural CNF from kenaf bast fibre for the application as a support structure in enzyme immobilization. The treatments involved for this preparation were delignification, bleaching and high-intensity ultra-sonication process to obtain nanofibre with high cellulose content and…
The main results of the complex investigations of properties of high-strength weldable pseudo-α titanium alloys of the compositions 6%Al, 1.5%V, 1.0%Mo, 0.5%Zr, 0.1%C and 6%Al, 2.0%Mo, 0.5%Zr, 0.1%C, which determine their efficient use in components and units of transport steam-turbine plants, are considered. The stre…
The data on homoand heteroleptic molecular and ionic Sc, Y, and lanthanide thiocyanates are systematized and generalized. The influence of the metal cation, its coordination number, and the ligand environment on the formation of the coordination sphere and stereochemistry of rare-earth metal thiocyanates is studied. T…
The diffraction of a spatiotemporal optical pulse by a resonant diffraction grating is considered. The pulse diffraction is described in terms of the signal (the spatiotemporal incident pulse envelope) passage through a linear system. An analytic approximation in the form of a rational function of two variables corres…
Novel Non Conductive Film (NCF) was developed for high productivity process. To meet high productivity, we add viscosity stability on a hot stage and snap cure property at higher than 140C. In addition, the NCF is transparent for optical alignment process.
For anti-icing, supercooled water should be removed before frozen onto the contact surface. We use a hydrophobic coating for anti-icing and introduce the static- and dynamic-evaluation methods. The methods describe the contact surface between the hydrophobic surface and a supercooled-water droplet. The former is based…
Abstract A new diarylethene derivative containing an aminoquinoline unit was synthesized and its structure was determined by single crystal X‐ray diffraction analysis. Its properties such as photochromism, fluorescent switches and detection for metal ions were measured. The results indicated that the closed‐ring of th…
Interest in the development of new bioresorbable structures for various tissue engineering applications is on the rise. In the current study, we developed and studied novel soy protein-based porous blends as potential new scaffolds for such applications. Soy protein has several advantages over the various types of nat…
Three types of coal gangue are compared systematically. The burnout index and the comprehensive combustibility index are found to increase significantly as the ash content decreases. The Arrhenius activation energy is obtained by using the Ozawa-Flynn-Wall and Vyazovkin models.
Magnetic behavior of Bi3Nb1–x Mn x O7–δ solid solutions of cubic and tetragonal modifications has been examined in comparison. The magnetic susceptibility studies have revealed that paramagnetic manganese atoms in the solid solutions of cubic and tetragonal modification exist as Mn(III) and Mn(IV) monomers as well as…
This paper investigates and analyses use of numerical modeling by finite element method (FEM) at studying of consolidation processes of materials from powder by spark plasma sintering (SPS). Tasks of SPS process optimization is discussed in detail. Examples of numeric analysis of SPS of current conducting and non-cond…
We investigate the electronic structures of FeSe in the presence of different possible orders and spin-orbit coupling (SOC). It is found that only the ferro-orbital order (FO) and the collinear antiferro-magnetism (C-AFM) can simultaneously induce splittings at σ and M. Bicollinear antiferro-magnetism (B-AFM) and SOC…
Abstract This work shows the synthesis and structural, spectroscopic, and electrochemical properties of Mn III complexes supported with pyrrole‐ and indolecarboxamide ligands. In all cases, the respective ligand constitutes a N 4 coordination sphere about the Mn III ion. The Mn III complexes of pyrrolecarboxamide liga…
Abstract The reaction of the rigid polydentate Schiff‐base H 3 L with different dysprosium carboxylates afforded two novel centrosymmetrical dinuclear Dy III compounds, [Dy 2 (HL) 2 (CH 3 COO) 2 (DMF) 2 ] ( 1 ) and [Dy 2 (HL) 2 (PhCOO) 2 (DMF) 2 ] · 4DMF ( 2 ) with differing carboxylate groups. The two differing carbo…
Zapas model has shown good results in characterizing viscoplasticity in polymers and composites. Typically all viscoplastic parameters for this model are obtained in creep and strain recovery tests at different stress levels and at different test length. Obtaining parameters for highly variable bio-based materials is…
This paper deals with the occurrence of Partial Discharges on electrical equipment due to the high electric field exceeding the electric strength of Air. We can model PD occur in electrical equipment by using 4 types of electrode arrangement. There are Needle-Plane, Needle-Sphere, Needle-Needle, and Needle-Sphere. In…
In order to develop the neutron absorbing and shield materials, a hot-rolled 0.02%-Gd duplex stainless steel was prepared with 55 vol. % of ferrite and 45 vol. % of austenite. The σ phase with an average grain size of 9–11 μm in austenitic (γ) grains tended to be elongated parallel to the rolling direction, with (100)…
In situ characterization of micro- and nanoscale defects in polycrystalline thin-film materials is required to elucidate the physics governing defect formation and evolution during photovoltaic device fabrication and operation. X-ray fluorescence spectromicroscopy is particularly well-suited to study defects in compou…
Tungsten oxide (WO 3 ) nanoparticles were synthesised by a simple chemical precipitation method in various media, such as acidic, basic and neutral. Hydrochloric acid and sodium hydroxide were used to maintain the different pH levels and tungstic acid was used as the precursor for the synthesis of tungsten oxide. The…
