Self‐ordered anodised aluminium oxide membranes can be used as a base for the growth of different nanoarrays. In this reported work, an efficient and effective method is implemented to fabricate highly ordered alumina nanowires (ANWs) covered with a uniform shell of 12 ± 2 nm Sn nanoparticles (Sn/ANWs). A two‐step ano…

New species H. hovsgolensis Vishnjakov, Kuliko…
Objective(s):Despite of wide range applications of polymeric nanoparticles in protein delivery, there are some problems for the field of protein entrapment, initial burst and controlled release profile. Materials and Methods: In this study, we investigated the influence of some changes in PLGA nanoparticles formulation…
The distribution and the microstructure of carbides and pearlite, orientation relationships of pearlitic component phase in 100Mn13 steel by solution treatment at 1050 °C and aging treatment at 525 °C were investigated by optical microscope and transmission electron microscope. The results show that there is a large n…
Inhibition of copper corrosion in 0.1 mol dm-3 Na2SO4 solution (pH 3) by two thiazole derivatives of 5-(5'-methylfurfurylidene-2')-2,4-dioxotetrahydro-1,3-thiazole (MFDT) and 2-thiono-5-(4'-ethoxybenzylidene)-4-oxotetrahydro-1,3-thiazole (TEBOT) was studied by weight loss and potentiostatic polarization measurements.…
This paper presents the combination technique in developing the woven kenaf fiber that is used as a new method to improve energy absorption performance. This method focuses on the effect energy absorption of angle orientation. Due to the low density, natural fiber such as kenaf fiber provides comparatively good mechan…
Titanium alloys present favorable properties to industry applications that depend on their composition and microstructure. Adding alloy elements and thermomechanical treatments can change the microstructure of titanium alloys. In this paper, Ti-15Zr alloys with different molybdenum quantities were prepared and hot-rol…
A study of crystalline structure, magnetic and magnetocaloric properties of Dy(Co 1- х Fe х ) 2 (х = 0.10, 0.15) intermetallic compounds was undertaken. Phase composition was controlled by X-ray diffraction analysis. Magnetic properties were measured with a help of SQUID magnetometer in magnetic fields up to 7 Т in th…
The intelligent systems of smart textile should contain flexible electronics, for example, sewn or stitched textile elements that function as conductive traces, sensor elements, electrodes or switches. The experiments for development of sewn touch and push switches are performed. For this reason silver coated multifil…
In this work we report the results of investigation of the magnetocaloric effect in Gd 100- x Y x ( x = 0, 5, 10, 15) cold rolled ribbons. It is shown that the magnetocaloric effect exists within a wide temperature interval 258-295 K and it is comparable with the magnetocaloric effect observed in bulk samples of pure…
In this paper, the microstructural and textural characteristics of a series of nanocrystalline CeZrFeO2 (CZF) loaded with different concentration of Fe were reported. Nanocrystalline CZF was synthesized at room temperature using water-in-oil microemulsion method. The microstructure and textural properties of CZF nanoc…
Utilization of flyash which is produced at large scale in coal based thermal power plant is a challenge. In this regard, our investigation provides distinctive way of utilizing flyash for designing and preparing high-performance EMI shielding materials. Herein, we report synthesis and characterization of multiwalled c…
This paper reviews the emergence and progress of phosphorene FETs, all within about a year. In such a short time, back-gated FETs evolved into top-gated FETs, gate length was reduced to the sub-micron range, passivation by high-k dielectrics or hexagonal boron nitride was demonstrated with temporal, thermal and mechan…
The study of production, transfer and accumulation of space charge in silicon rubber (SIR) under direct current (DC) is significant for the research of new high voltage (HV) DC cable accessories and the accessories' stable operation. In this paper, based on SIR materials used for cable accessories and the actual low w…
The effect of voltage ramp rate on the short-term dielectric breakdown strength of polymer nanocomposites is not well-documented. In this paper, the effect of DC field ramp rate on the large-area breakdown performance of melt-extruded bi-axially oriented polypropylene (BOPP) films incorporating 4.5 wt-% of nano-silica…
The absorbed moisture of epoxy resins (ER) and epoxy resin impregnated paper (ERIP) composites have a great influence on the insulation of ultra-high voltage direct current (UHVDC) bushings. The ER and ERIP samples were prepared according to a certain formulation. The moisture absorption behaviors of ER and ERIP in de…
Complex electric modulus is defined as the inverse of complex relative permittivity. In this paper, it is clearly shown by referring to the author's experimental results that electric modulus can be a significantly powerful tool for the analysis of dielectric behavior of various insulating polymers. The modulus is esp…
The lack of well defined abstraction levels and immature design tools have made the custom design and optimization of analog circuits slow, complex and laborious. Furthermore, CMOS technology beyond 10 nm faces fundamental limits which may restrict its applicability for future devices. In this paper, a Graphene Field…
UHV AC GIS spacer is the critical component of gas insulated switchgear (GIS) in UHV substation. It plays a supporting conductor, isolating chamber and electrical insulation role.
