Why are nanomaterials such a hot ticket? It's all about size. Thanks to their small dimensions (at least one dimension fewer than about 100 nm) and, therefore, high ratio of surface area to volume, nanoparticles have some very unusual and interesting chemical and physical properties. Ranging from melting point and ele…
Alumina ceramics can be widely used in electro vacuum area and microwave communication industry due to its excellent dielectric properties. However, the effects of the Y2O3addition on dielectric properties of alumina ceramics were rarely investigated. In this paper, alumina ceramics was prepared using Y2O3as additive,…
In this paper, dry ice is converted into few-layer graphene, which can be dispersed stably in N, N-Dimethylformamide (DMF) by adding pyrene-1-boronic as a stabilizer that non-covalently functionalizes the surface of graphene to obtain homogeneous colloidal suspensions. Moreover, we make use of vacuum filtration transf…
In the present study, an optimization strategy based on desirability function approach together with response surface methodology has been used to optimize turn-aided deep cold rolling process of AISI 4140 steel. A regression model is developed to predict surface hardness. In the development of predictive model, rolli…
The University of Manchester is one of the leading academic nuclear research centres in the UK. An import part of the engineering research at Manchester is being conducted to support the decommissioning plan for the Sellafield nuclear site in Cumbria. The primary focus of this research is the remote characterization o…
Abstract Understanding both the origin and procedures for removing inclusions in magnesium alloys results in castings with enhanced mechanical and corrosion properties. This article provides an overview of typical inclusions found in magnesium and its alloys, various techniques used to determine inclusion content, and…
Equal channel angular pressing (ECAP) is a materials processing method that allows very high strains to be imposed, leading to extreme work hardening and microstructure refinement. Cast Cu-2, 5 and 10 wt% Sn alloys in the form of 25mm diameter and 300mm long rods are ECAPed through 12 mm diameter, 120o inner angle, an…
Infectious diseases are responsible for thousands of worldwide early death .Many commercial antibiotics have been used to control human's infectious diseases all over the world. Calotropis procera Linn a wild growing plant of Asclepiadaecae family is known to possess multifarious medicinal properties. Total 80 non rep…
A new μ1,1-OMe-bridged dimeric iron(III) complex, [Fe2L2(μ1,1-OMe)2(NCS)2], where L is the deprotonated form of 2-[(2-ethylaminoethylimino)methyl]-5-methoxyphenol, has been prepared and structural characterized by elemental analysis, IR spectrum, and single crystal X-ray crystallography. The complex crystallizes in th…
Metamaterials with zero phase delay can guide light over hundreds of wavelengths without introducing phase variations so as to reduce the unwanted effects of frequency dispersion, which has been widely studied by researchers in the world. Based on the research works of our group, in this paper we summarize and review…
In this research the influence of adding SiC on microstructure and electrical properties of ZnO-based Nanocomposite varistors were investigated. SiC was added with amounts of 10-0 mass% to ZnO-based varistor composition. It is found that SiC allows reaching to high threshold voltage with formation of fine-grained ZnO.…
Clay is a mineral particles composed of silica-alumina base frame, has a layered structure and a hollowed space causing surface becomes very widespread and effective as an adsorbent. Adsorbent of clay is very effective to adsorb cation for having negatively charged surfaces, but its ability to adsorb anion is very low…
A 40-year-old Caucasian female patient presented to the outpatient General Surgery ward in "V. I. Lenin" Teaching Hospital complaining of a recurrent mesogastric pain that had lasted for 3 months. Physical examination showed a palpable mass confined to that area. She was then admitted with diagnosis of an abdominal tu…
The transmission of normally incident plane wave through an array of subwavelength metallic slits curved with a single step or mutli-step has been explored theoretically. The transmission spectrum is simulated by using the finite-difference time-domain method. The influences of surface plasmon polaritons make the end…
A recycled waste plastic (recycled high density poly ethylene RHDPE and recycled low density poly ethylene RLDPE) are exposed to environmental conditions during the usage for many years ago. Also the chemical contaminants in the internal composition had effects on the thermo-mechanical and other properties for these w…
Harmonic current is one of the major power quality problems due to non linear loads. In this paper the harmonic current in induction furnace load is compensated using active power filter. The inverters and rectifier switching creates harmonics in input side. It is then compensated by using active power filter with p-q…
Microstructure control in thin-layer multilayer ceramic capacitors (MLCCs) is one of the challenges for increasing capacitive volumetric efficiency and high voltage dielectric properties. In this paper, the X5R-MLCCs with ultra-thin dielectric layers (~1.2 μm) owning uniform grain size distribution were prepared by we…
This paper discusses transmissive ruled diffraction gratings. Recommendations are given concerning the choice of their design and parameters that provide high diffraction efficiency in the specified spectral region, in particular for determining the optimum line frequencies. Examples are given of diffraction gratings…
Uniform BaTiO3 polycrystalline coating layer on Ni nanoparticles is achieved by a novel sol-precipitation method. The Fourier transform infrared spectra (FT-IR) of the coated samples inhibit that there is typical Ba-O and Ti-O bond for crystalline BaTiO3.The influence of reaction time on the properties of the coated s…
A new technique for the formation of diamond-like carbon thin films with high growth rate on silicon wafers and glass surfaces was investigated. A pulsed plasma source based on disk magnetohydrodynamic accelerator was used; methane was a precursor. Scanning electron and atomic-force microscopy, X-ray photoemission spe…
