Arsenic-doped ZnO films were fabricated by radio frequency magnetron sputtering method at a relatively low substrate temperature of 200 °C. Post-growth annealing in air was carried out up to a temperature of 1000 °C. The samples were characterized by Hall measurement, positron annihilation spectroscopy (PAS), secondar…
The voltage hold-off capability of 95% alumina insulator in vacuum is usually less than that of a similar-sized vacuum gap and also is far below its dielectric breakdown strength, due to its low surface flashover strength. In this work, bulk doping was taken into consideration to modify the surface of 95% alumina in h…
We investigate performance, scaling, and reliability of 3D stacked multilayer graphene (s-MLG) as a new material candidate for carbon based interconnects, aiming to break through the limit of graphene monolayer in which electrical conduction and the associated wire scalability and reliability are largely hampered by i…
Before nitrogen can be used as a radiator for edge plasma temperature control in experiments with beryllium as the wall material, the compatibility of nitrogen-containing plasma with beryllium has to be tested. Therefore beryllium samples were exposed to a variety of mixed N 2 /D 2 plasmas in PISCES-B and codeposits f…
Experimental simulations of ITER transient events with relevant surface heat load parameters (energy density and pulse duration) as well as particle loads were performed with a quasi-steady-state plasma accelerator Kh-50 and pulsed plasma guns. Additional shielding was observed during irradiation of the combined carbo…
Pure and Ni (2 at.%) doped cadmium sulde (CdS) nanoparticles have been synthesized by chemical co-precipitation method at room temperature. Eect of Ni doping on CdS compound semiconductors has been analyzed using X-ray diractometer, transmission electron microscope, energy dispersive spectroscopy, Raman and optical ab…
We report periodic ab initio total energy calculations to predict equilibrium morphology of molecular crystals. The approach is based on the adsorption of molecules upon the underlying crystal surfaces rather than the attachment of two-dimensional slices of thickness of interplanar distance. It takes into account the…
We examine the evolution of a liquid drop on an inclined substrate oscillating vertically. The drop is assumed thin, and the oscillations are assumed weak and slow (the latter makes the liquid's inertia and viscosity negligible, so the drop's shape is determined by a balance of surface tension, gravity, and vibration-…
The aim of this study was to investigate the suitability of using water melon peels as alternatives to wood-based particleboard composites. The water melon peels composite boards were produced by compressive moulding using recycled low density polyethylene (RLDPE) as a binder. The RLDPE was varies from 30 to 70wt% wit…
This work reports on Raman scattering of rhodamine (R6G) molecules absorbed on either randomly distributed or grating-like arrays of approximately 8-nm Ag nanoparticles developed by inert gas aggregation. Optimal growth and surface-enhanced Raman scattering (SERS) parameters have been obtained for the randomly distrib…
The effects of tetravalent hafnium doping on the structural, transport, and magnetic properties of polycrystalline La1−xHfxMnO3 (LHMO) (0.05 ≤ x ≤ 0.3) were investigated systematically. LHMO exhibited a typical colossal magnetoresistance effect via the double-exchange between Mn2+ and Mn3+ ions, instead of that betwee…
Deuterium ion-driven permeation through three different types of W specimens with varying grain size was measured as a function of temperature (500 K< T <1100 K). The steady-state permeation flux was microstructure independent and the inverse relationship with specimen thickness holds within a factor of two over the e…
Extensive environmental concern associated with the disposal of solid plastic wastes has stirred tremendous interest in the production and use of sustainable biodegradable polymers. Among the vast variety of available materials, Polylactic Acid (PLA) standout as the most commercially viable mass produced resin to date…
Abstract Monoclinic and hexagonal CePO 4 nanoparticles and nanorods were successfully synthesized from Ce(NO 3 ) 3 ·6H 2 O and Na 3 PO 4 ·12H 2 O solutions at pH 1–5 by a 180 W microwave radiation for 60 min. The products were characterized by X‐ray diffraction (XRD), Fourier transform infrared (FTIR) spectroscopy, an…
Abstract Fassinaite, ideally Pb 2 2+ (S 2 O 3 )(CO 3 ), is a new mineral from the Trentini mine, Mount Naro, Vicenza Province, Veneto, Italy (holotype locality). It is also reported from the Erasmus adit, Schwarzleo District, Leogang, Salzburg, Austria and the Friedrich-Christian mine, Schapbach, Black Forest, Baden-W…
0.95 (Na0.5Bi0.5)TiO3-0.05 BaTiO3 +1 wt% Bi2O3 (NBT-BT3) ceramic is used as target to deposit the NBT-BT3 thin films. The excess 1wt% Bi2O3 is used to compensate the vaporization of Bi2O3 during the sintering and annealing processes. NBT-BT3 thin films are successfully deposited using radio frequency (RF) magnetron sp…
Humic acid (HA)-coated Fe 3 O 4 ( Fe 3 O 4 /HA) superparamagnetic nanoparticles were synthesized by a chemical co-precipitation method with cheap and environmental friendly iron salts and HA. The as-synthesized samples were characterized by X-ray diffraction (XRD), high resolution transmission electron microscopy (HRT…
A Schiff base, namely N-(2-hydroxybenzylidene) thiosemicarbazide (HBTC), was investigated as inhibitor for carbon steel in saline water (SW) using electrochemical measurements such as: potentiodynamic polarization and electrochemical impedance spectroscopy (EIS). The morphology of the surfaces before and after corrosi…
The optical transmittance of nanostructured cubic PbS (lead sulfide) films with a D03 structure is measured in the wavelength range 300 to 3200 nm. The film thicknesses are in the range ∼120 to ∼400 nm. Electron microscopy of the microstructure shows that about half of the films’ particles are 60 nm or smaller in size…
Various types of epoxy/BN composites were prepared to optimize material conditions for high thermal conductivity and high breakdown strength. The best composite was found to be epoxy/conglomerated h-BN/ nano silica nano micro composite with thermal conductivity 12 W/m·K and BD strength 15 kVpeak/0.2 mm. One of the mos…
