Zinc acetate dehydrate as starting material along with diethanolamine as stabilizer, and isopropyl as a solvent were used to synthesis ZnO thin films in different low molarities. Sol-gel spin coating method was used in depositing ZnO on porous silicon substrate surface. In other to prepare substrate, p-type silicon wa…
Electrospun nanofibres are an excellent cell culture substrate, enabling the fast and non-disruptive harvest and transfer of adherent cells for microscopical and biochemical analyses. Metabolic activity and cellular structures are maintained during the only half a minute-long harvest and transfer process. We show here…
Decontamination of fuel pins is an important process step in nuclear fuel fabrication. Decontamination assumes greater significance with respect to fuels containing plutonium, owing to both plutonium’s high radiotoxicity arising from its long biological half-life and its relatively short radioactive half-life. The adv…
In the present study, the role of pH on the corrosion behavior of two titanium alloys, beta Ti-15Mo and mixed Ti-6Al-4V has been examined in phosphate buffer saline solution at the open circuit potential (OCP) and at 1 V vs. SCE anodic potential. The techniques involved were Open Circuit Potential (OCP), Electrochemic…
BACKGROUND: Cancer is a potentially fatal diagnosis, but due to modern medicine there is a potential cure in many of these cases. The rate of treatment success depends on early disease detection and timely, effective delivery of tumour specific treatment. There are many ongoing researches aimed to improve diagnostics…
Herein, the effect of different TM (Co, Ni and Cu) doping on structural, optical and magnetic properties of ZnO nanostructures has been studied. Zn1−x TM x O (TM=Co, Ni and Cu) nanostructures were prepared by a microwave assisted chemical route and characterized by X-ray diffraction (XRD), field emission scanning elec…
The corrosion behavior of welded maraging steel in sulfuric acid solutions has been studied over a range of acid concentrations and solution temperatures by electrochemical techniques such as Tafel extrapolation and electrochemical impedance spectroscopy. The studies have revealed that the corrosion rate of welded mar…
We report 75 As NMR studies on single crystals of rare-earth doped iron pnictide superconductor Ca 1− x Pr x Fe 2 As 2 . In both cases of x = 0.075, 0.15, a large increase of ν q upon cooling is consistent with the tetragonal-collapsed tetragonal structure transition. A sharp drop of the Knight shift is also seen just…
This paper focuses on the evaluation of the performances of three different antenna sensors suitable of Partial Discharge (PD) measurements. Monopole, triangular and spherical antennas were simulated by means of the surface moment method. The transmitting system is modeled by a power electronic device with a fault cur…
Halloysite Nanotubes (HNTs) are nanomaterials composed of double layered aluminosilicate minerals with a predominantly hollow tubular structure in submicron range. HNTs are characterized by a wide range of applications in anticancer therapy, sustained agent delivery, being particularly interesting because of their tun…
Abstract Polymer grafting of carbon black (CB) has been intensely researched as polymer modification is one of the effective means for improving the solubility and compatibility of carbon black. Recent advances in the polymer grafting methods allow the introduction of polymers with well controlled composition, structu…
In the new research plan of Plasma Research Center of the University of Tsukuba, a high heat-flux divertor simulator (E-Divertor) was proposed by using an end-mirror exit of a large tandem mirror GAMMA 10/PDX device. Experiments for characterization of end-loss plasma flux have been extensively performed at the end-mi…
After giving the specifications of compact plasma device for the study on plasma-wall interactions, AIT-PID, focusing on the electron energy distribution of helium plasmas, the experimental and analytical results for the determination of power transmission factor through the sheath formed on the helium defected tungst…
Solid polymer electrolyte based on poly (vinyl pyrrolidone) (PVP) complexed with different weight per cent ratios of KClO4 salt was prepared using solution cast technique. The complexation of the salt with polymer was confirmed by Fourier t ransform infrared (FT-IR) spectroscopy studies. Electrical conductivity was me…
Enhancement of the catalytic activity of phthalocyanine catalysts by their immobilizing on polymer matrices has been studied. It has been found that the immobilization of sulfonated cobalt phthalocyanines on polymers enhances their catalytic activity in the oxidation of sodium diethyldithiocarbamate with air oxygen un…
For phase-change memory to be considered a true universal memory it would have to combine MLC storage, for low cost per bit, with adequately high endurance and at least moderate data retention. However, this appears to be particularly difficult to achieve, because of phenomena such as material segregation, which comes…
The influence that manufacturing processes have on electrical steel properties is investigated. The investigation is carried out by considering changes in measured electromagnetic quantities and the changes to parameters of a physics-based hysteresis model. The parameters of an inverse Jiles-Atherton hysteresis model…
De-oiled cakes could be a potential source of renewable energy that can supply liquid and gaseous fuels through thermo-chemical conversion processes. Thermal properties and reaction kinetics of de-oiled cakes play prominent role in design, operation, and modeling of these systems. In the present work, thermogravimetri…
Zinc oxide (ZnO) powders were synthesized by a simple precipitation and a hydrothermal process at the temperature range RT-100°C. In precipitation process, the powders were formed by mixing aqueous solutions of zinc nitrate with NaOH aqueous solution under controlled process conditions such as precursor concentration,…
Natural fibre-reinforced composites were prepared using a lignin-phenolic resol binder, in which 30 wt.-% of the phenol was substituted by a modified lignosulfonate from renewable resources. The reinforcement of the lignin phenolic binder matrix was accomplished by different natural fibres. The non-woven flax, flax/wo…
