With the aim of invesgating effect of the two polymer phases of ABS on improved fire performance of ABS filled with magnesium hydroxide, we have prepared ABS filled with surface-treated magnesium hydroxide (MH) via compounding poly (styrene-acrylonitrile) (SAN) and polybutadiene filled with MH as well as by compoundin…
In this paper we study unusual optical properties of a metasurface composed of two orthogonal metal strips located on both sides of a thin polymer film. Combination of strong electric and magnetic dipolar resonances leads to resonance for both co- and cross-polarizations in the range of 150-250 GHz. Elasticity of the…
Our simulation reveals that the programming current of phase change memory (PCM) is expected to dramatically reduce to tens of μA with the help of a heating layer. TiSiN films by reactive RF magnetron co-sputtering are investigated for application to the heating layer of the ultra-low-current PCM. The resistivity of T…
The study of NiFe magnetic nanoparticles (MNPs) has a wide range of applications because of the unique composition and its magnetism. In this paper, a brief review is presented on the different methods for the preparation of the bimetallic magnetic nanoparticles, along with our preliminary work on the synthesis of thi…
The aim of this paper is to present the results of laboratory research on Ionic Polymer-Metal Composite (IPMC), in context of energy harvesting applications. IPMC is a novel type of material, a smart polymer, which can work as a sensor or an actuator. One of its biggest advantages is low actuating voltage of about 4V…
In this work, the crimp properties of PTT/PET bicomponent filament with different component ratios were investigated. The results show that, after boiling water treatment for 15 minutes, the crimpability of 50/50 component ratio is superior to that of 40/60 and 60/40 component ratio. Heat treatment can realize the shr…
In this study rubber toughened polyester composite filled with kenaf was exposed in different environmental condition such as in artificial sea water (SW), distilled water (DS), environment exposure (Ex) and soil exposure (SL). Rubber-toughened polyester-kenaf fibre composites were prepared by adding 25% of kenaf fibr…
This article refers to the design technique related to the cross-section absorption properties of the materials absorbing electromagnetic waves. The methodology of construction of absorber, measurements of microwave absorption, description of the original laboratory set-up for measuring the absorption characteristics…
Through testing and analyzing Surface micromorphology of protective film and elemental composition and content of vacuum counter-pressure filling AZ91D magnesium alloy by SF6 mixed gas, the effect of SF6 concentrations on protective film of vacuum counter-pressure filling molten magnesium alloy was studied. The result…
TiO2adsorption on GaN(0001) line defect surface has been explored by employing density functional theory. The total energy, density of states, surface energy (adsorption energy), formation energy and electron density of the various models have been obtained. Our calculations indicate that the model containing [11 line…
The physiological state of E. coli K12 bacterial cells under the action of TiO 2 nanoparticles (0.04 g/L) was investigated with the method of staining by an acridine orange fluorescent dye in order to elucidate the mechanism of the antibacterial activity of nanoparticles. Experiments were performed in deionized water…
Fibre materials, as thermal insulation materials, will be an optimum choice for inflatable mini cold storage. The evaluation index such as infrared spectrum, thermal stability and thermal conductivity is closely related to the selection and application of fibrous insulation materials. The results showed that the trans…
We present calculations of the total and m-fold electron-loss cross sections using the DEPOSIT code for highly charged U(q+) ions (q=10,31,33) colliding with Ne and Ar targets at projectile energies E=1.4 and 3.5 MeV/u. Typical examples of the deposited energy T(b) and m-fold ionization probabilities Pm(b) used for th…
Combined with the pre-test results, homogenization, plastic deformation, aging and other processes of Mg-7.1Gd-4.6Y-1.3Nd-0.5Zr (EW75) magnesium alloy was studied in engineering tests. The results show that in engineering test the large ingots (Φ500×800~900mm) of the EW75 alloy using two-stage homogenization treatment…
Nuclear quadrupole resonance (NQR) is a newly developed branch of radio frequency (RF) spectroscopic technique, allowing the detection of many substances containing quadrupole nuclei, such as14N and35Cl, widely existing in explosives and narcotics respectively. In this paper, we focus on the research of its detection…

Trivalent chrome has an abroad application in the area of leather tanning, electrolytic plating and dyeing due to the strong capability of coordination. Pollution caused by chrome salts cannot be ignored. This paper proved that the chrome tanning wastewater can be treatment by chrome chelates (CRBD). The supernatant w…
The ultraviolet-induced one-dimensional vibration of Ti ions in the red phosphor Sr(Ti0.939,Al0.061)O3:Pr3+ was successfully visualized using high-resolution X-ray diffraction, which was already predicted by X-ray absorption spectroscopy. The vibration of Ti 3d-eg states becomes clear with decreasing temperature, acco…
In this paper, we report about the first experimental verification of evanescent waves enhancement inside wire metamaterial. The enhancement is originated by resonant pumping of standing waves inside the wire metamaterial. An excellent agreement between the experimental data and numerical results is found. Furthermore…
Laser driven mass transportation on a single carbon nanocoil (CNC) has been investigated, by regulating the controlling current and the laser focus position. It is found that a paraffin microsphere on a single CNC can be removed by the irradiation of an infrared laser beam on the CNC body near themicrosphere. This phe…
