In this study, QUV accelerated weathering of polyvinyl chloride (PVC) composites with different amounts of titanium dioxide (TiO 2 ) particle was conducted to investigate the effect of TiO 2 particle on the surface morphology and the mechanical properties. The results indicate that the surface morphology of PVC withou…
Disposal of polyethylene used as carry bags is the greatest challenge increasing day by day. Composite materials were prepared by mixing Fly ash (FA) and nanostructured fly ash (NFA) from thermal power station as filler and blends of Waste polyethylene (WPE)(carry bags) collected from municipal solid waste (MSW) with…
Solid particles can be used as stabilizers for oil/water (o/w) emulsions instead of the conventional surfactants. Emulsion polymerization of styrene, as an example of polymerizable oil, was started in the current study after ultrasonication of the monomer into aqueous phase with aid of montmorillonite nanoplatelets as…
An aluminium phosphate based high emissivity coating has been deposited on Ni based superalloy C-263 by dip coating method wherein the substrate was immersed in a chemical sol followed by curing of the green coating. Deposition of the coating by spraying the sol on the substrate surface has also been explored. The pre…
In order to improve toughness of rigid poly(vinyl chloride) (PVC), we prepared multilayer graphene (MLG) filled PVC composites through conventional melt‐mixing methods by taking advantages of easy dispersion and high flexibility of graphene. Microstructure, static, and dynamic mechanical properties of the MLG/PVC comp…
The damage profile of oxide dispersion strengthened steels after single-, or simultaneous triple-ion irradiation at different conditions has been characterized using a low energy positron beam in order to provide information on microstructural changes induced by irradiation. Doppler broadening and coincident Doppler b…
Those researchers who are part of the metamaterials community stand at a fork in the road – does the maturation of metamaterial fabrication lead to a focus on applications and technology, or does it suggest an opportunity to pursue more blue-sky scientific concepts? At Metamaterials 2013 in Bordeuax, one speaker focus…
Strontium and magnesium doped ceria solid solutions (Ce0.99Sr0.01O1.995 and Ce0.99M0.01O1.995) were synthesized by a cost effective solid state reaction. The doped and un-doped CeO2 samples were sintered at 1200 °C, 1300 °C and 1400 °C to investigate the effect of sintering temperature and doping on density, structura…
Natural marine polysaccharides such as chitosan, sodium alginate and carrageenan; after depolymerization by different techniques, have shown promising plant growth promoting and other biological activities. Chitosan after irradiation with Co-60 gamma-rays have proven to be a miraculous plant growth promoter in differe…
High-energy synchrotron X-ray diffraction was used to investigate the isothermal precipitation of δ-hydride platelets in Zircaloy-4 at a range of temperatures relevant to reactor conditions, during both normal operation and thermal transients. From an examination of the rate kinetics of the precipitation process, prec…
The crystal size distribution in polynuclear growth is numerically studied using a coupled map lattice model. The width of the size distribution depends on c/D, where c is the growth rate at interface sites and $D$ is the diffusion constant. When c/D is sufficiently small, the width W increases linearly with c/D and s…
Here, we report a general and facile method for effective layer-by-layer exfoliation of transition metal dichalcogenides (TMDs) and graphite in water by using protein, bovine serum albumin (BSA) to produce single-layer nanosheets, which cannot be achieved using other commonly used bio- and synthetic polymers. Besides…
The quantum confinement effect and phonon scattering in low dimensional nanostructure is effective in the improvement of the efficiency of thermoelectric generators. Bi2Te3 nanowire arrays were prepared in Al2O3 templates through the use of electrochemical deposition. Chemical mechanical planarisation was employed to…
Lithium-zinc-titanium ferrite synthesis under the high energy action, including mechanical activation of initial reagents mixture in a planetary mill and subsequent heating of reaction mixture by a high-energy electron beam, is investigated using x-ray diffraction and thermal analyzes. The composition of initial reage…
The ferromagnetic La1-xSrxMnO3+δparticles have recently been prepared from the flux of sodium nitrite at ≈500°C [1,2]. The advantage of this facile method is the high yield of cubic-shape nanocrystals without a very fine matter that is common for an alternative preparation via sol-gel route. The size of the as-prepare…
Due to excellent magnetic properties, sintered Nd-Fe-B magnets have been used in various fields for many years [1, 2]. However, Nd-Fe-B magnets show a relatively low temperature stability of performance which is a main disadvantage for the application in some special cases. In order to improve the temperature stabilit…
A cetirizine hydrochloride polyvinyl chloride (PVC) membrane drug sensor was developed by using an ion association complex generated with sodium tetraphenylborate and cetirizine hydrochloride as an electroactive substance. In a sodium dihydrogen phosphate–sodium hydroxide buffer solution of pH 5·0, the linear range of…
Subject of the paper is the simultaneous variation of the electrical and rheological properties of vacuum deposited thin layers on flexible substrates and on textile substrates: fiber, threads and fabric, different foils. The aim of the study is oriented to establish the optimal technological regime and the selection…
The study is concerned with two types of disordered epitaxial graphene: (i) graphene with randomly located carbon vacancies and (ii) structurally amorphous graphene. The former type is considered in the coherent potential approximation, and for the latter type, a model of the density of states is proposed. The effects…
This work is focused on an experimental study of E26-2 pipeline steel tearing by mode III. The crack propagation length is obtained as a function of the applied force magnitude for specimens of different thicknesses and widths. The critical stress intensity factor and the essential work needed for crack propagation ar…
