Polycrystalline aggregate models are built based on the theory of Voronoi diagram, then crystal plasticity finite element method (CPFEM) is used to study the relationship of microstructures and stress-strain responses in Ti-6Al-4V alloy during uniaxial tensile tests at room temperature. Stress-strain responses of the…
Operating the microfocus X-ray source at high power is required to achieve high temporal reso- lution. However, the thermal loading of the anode focal spot is a limiting factor in determining the maximum power of an x-ray tube. In this paper, a transmission window based on polycrystalline diamond, for improved brightn…
A detailed study on the morphological evolution of one-dimensional (1D) vanadium pentoxide (V2O5) nanostructures was performed. Small-angle X-ray scattering (SAXS) and electron microcopy techniques were used for the analyses of the influence of synthesis parameters on a hydrothermal synthesis method of V2O5 nanostruct…
Having a great number of concrete structure classifications it is recommended to specify the following three principal types: microstructure – cement stone structure; mesostructure – structure of cement-sand mortar in concrete; macrostucture – two-component system that consists of mortar and coarse aggregate. Every me…
In the present study, in-situ UV reduction of graphene oxide (GO) during photo-polymerization of the epoxy-novolac nanocomposite and its effect on the thermal properties of nanocomposite were investigated at different loading level of GO. Chemical structure and structural distortion of GO before and after UV irradiati…
The ability of the complex hierarchical structure of nacre to withstand huge work of fracture beyond its constituent materials has generated much interest in its growth mechanism and biomimicry studies. However, the structural features directly involved in the robust mechanical properties have not been successfully id…
The research on the influence of melt processing with electromagnetic acoustic fields on the structure and properties of binary alloys Al–12%Si and Al–20%Si was conducted. The frequency of electromagnetic field induced in the loop antenna was changed between 500, 1000 and 2000 kHz during the experiments. Melts were pr…
A gold( <sc>i</sc> )–pyrazolato complex has been designed as a luminescent probe for cysteine (Cys).
The work represents the results of forming Zn-based nanoprecipitates in nanoporous amorphous silicon dioxide on silicon substrate by the template synthesis method. SEM and AFM images of the surface after chemical and electrochemical deposition of zinc were obtained. The analysis of photoluminescence of the precipitate…
Asian Journal of Chemistry, a Multidisciplinary Chemistry Journal is an Peer Reviewed International Journal and publishes from India. The journal has been established since January 1989 on a firm foundation of International Quality Research. This Journal encompasses all branches of chemistry and its sub – disciplines…
A multiband circular polarizer based on fission transmission of linearly polarized wave for x -band application is proposed, which is constructed of 2 × 2 metallic strips array. The linear-to-circular polarization conversion is obtained by decomposing the linearly incident x -polarized wave into two orthogonal vector…
The paper presents the development of high strength anticorrosive coating based on epoxy formulated with poly(aniline-co-2,3,4,5,6 pentafluoro aniline)/SiO2 composite. The composites display outstanding barrier properties against corrosive ions. SiO2 particles were found to significantly improve the microstructure of…
To extend directed self-assembly (DSA) of poly(styrene-block-methyl methacrylate), PS-b-PMMA, for higher resolution and potentially improving pattern line edge roughness (LER) and placement accuracy, we have developed a next generation material platform of organic high-χ block copolymers ("HC series", AZEMBLYTM EXP PM…
This article presents research findings on examination of quality of paving elements. Were investigated and analyzed performance properties of paving slabs on following: accuracy of geometric dimensions, appearance, compressive strength, frost resistance, water absorption and abrasion. Based on these results recommend…
Simple LED batch reactors have been constructed and used for the efficient and selective photooxidation of pyrroles and selected dienes.
The analysis of the service conditions of nuclear power constructions in case of low-cycle fatigue showed, that appearance of macrocrack is inadmissible. The conditions of safe operation require collecting of reliable information about material’s state at the stage of damage accumulation of dispersed microcracks. It w…
Jute fibres (Corchorus olitorious L.), an environmentally and ecologically friendly product, were chemically modified and treated as surface treatment which was carried out by mercerizing jute fabrics with aqueous solutions of NaOH (5,10 and 20%) at different soaking times (30, 60 and 90 minutes) and temperatures (0,…
We have studied the local structure and valence electronic unoccupied states of CsBi <sub>4</sub> Te <sub>6</sub> and CsBi <sub>3.5</sub> Pb <sub>0.5</sub> Te <sub>6</sub> ( <italic>T</italic> <sub>c</sub> ∼ 3 K) by EXAFS and XANES measurements.
In this paper, an aerosol-based process is shown for imparting antibacterial property to textiles. Metal nanoparticles (copper and silver) are produced by means of DC electrical discharges (glow and arc) between two electrodes in nitrogen at ambient pressure and passed through textile fabrics (cotton, polyester and ly…
This paper is devoted to computer modeling of composite structure the column base under question is contact interaction of bodies, which, when taken into account, allows to simulate the interaction of their constituent elements undergoing deformation. In modern tower buildings with braced framing, column structural de…
