ARIES-ACT1 power plant has been designed and configured to allow for rapid removal of full power core sectors followed by disassembly in hot cells during maintenance operation. To achieve high availability and maintainablity of a fusion power plant, power core components of a sector, including inboard and outboard FW/…
The thermal conductivity of wood-plastic composites in the solid and molten state (between 25 and 180 °C) is reported for polyethylene filled with pine wood flour (0 to 20%). The experimental data are compared with a simulation model to determine the effect of wood concentration. The results show that thermal conducti…
The structure and photoluminescence (PL) properties of Sr 3 SiO 5 : Sm 3+ and Li + -doped Sr 3 SiO 5 : Sm 3+ red-emitting phosphors were investigated. Samples were prepared by the high-temperature solid-state method. PL spectra show that the concentration quenching occurs when the Sm 3+ concentration is beyond 1.3 mol…
The aim of this study is experimental assay of sensitivity and stability of a bimetallic silver/gold SPR sensor chip. This chip utilizes the sensitivity of the silver and the stability of the gold. Moreover, the Silver layer (instead of usual Cr or Ti layer) was used as an adhesive intermediate layer between the Gold…
The effect of specimen surface curvature on profiles of asymmetric X-ray diffraction peaks obtained using the Bragg-Brentano geometry with a position sensitive detector (PSD) was studied. Asymmetric diffraction peaks were experimentally obtained from cylindrical surfaces with controlled curvature. Peaks were collected…
TiO 2 /X(X = Au and Ag) nanolayers are fabricated by depositing TiO 2 films using rf magnetron sputtering on thin quartz substrates embedded with Au and Ag nanoparticles. Enhancement of light absorption of the nanostructural layers is observed. These plasmonic and non-plasmonic materials are ordered in geometric arran…
We present the structural, surface and electrical properties of La 0.7 Ca 0.3 MnO 3 (LCMO) thin films of varying film thicknesses from 150 nm to 300 nm on single crystal LaAlO 3 (LAO) (h00) oriented substrate, prepared using Chemical Solution Deposition (CSD) technique. X-ray diffraction study shows that all LCMO film…
Abstract Intercalation of cationic surfactants hexadecylpyridinium (HDPy + ) and hexadecyltrimethylammonium (HDTMA + ) into the interlayer space of homoionic (Na-, Ca- and Zn-) smectites by solid-solid reactions was investigated. These reactions were complete within 15 min. Changes in the surface and structure of the…
Crystalline phases in heterostructures containing titanium and tungsten oxide films are studied after step annealing in vacuum at temperatures between 500 and 750°C. The films are deposited on a silica glass substrate by dc reactive magnetron sputtering. It is found that crystalline phases in single layers and bilayer…
The process of formation and structural organization of interpolymer complexes formed by macromolecules of poly( N -vinylpyrrolidone) and poly(methacrylic acid) chains grafted onto polyimide in solution is investigated via the method of polarized luminescence. A luminescent label of anthracene structure is covalently…
Molecular dynamics (MD) simulations were performed on molecular models of cellulose represented by two crystalline samples and amorphous samples. Simulated elastic properties and structures of each cellulose model were studied by MD simulations with the reactive force field and compared against experimental data for c…
Ammonium sulfate, ammonium bisulfate and ferric oxide are mixed at a molar ratio of 8:5:13 and heated in high temperature muffle furnace or fluidized bed at different temperature. To the sample, the thermal gravimetric (TG) analysis is used, the reaction residue is analyzed by fourier transform infrared spectroscopy (…
Epoxidation reaction is an important reaction in organic synthesis because the formed epoxides are intermediates that can be converted to a variety of products. Catalytic palm oil epoxidation using titanium-grafted silica, hydrogen peroxide, and peroxoformic acid was carried out at 60 °C in a fixed batch reactor. Tita…
Effect of grain size and Cl - concentration on corrosion behavior of Cu was investigated by using a series of electrochemical analysis in borate buffer solution (pH=8.40).The results indicated that in all cases, the Mott-Schottky plots of the passive films on the surface of Cu were linear with negative slop, and showe…
Abstract Protoporphyrinogen oxidase (PPO, EC 1.3.3.4) is one of the most significant targets for a large family of inhibitors that may be used as herbicide, bactericide, fungicide, or photosensitizing activator to treat cancer through photodynamic therapy (PDT). Molecular docking and CoMFA were combined in a multistep…
Effects from nonequilibrium superconductivity play a major role in the physics of superconducting nanoelectronics. Notably, charge imbalance arising from the point at which the superconducting device contacts normal-metal leads is prevalent, particularly in reduced dimensions. We investigate nonlocal transport signatu…
The optical properties of polypyrrole (Ppy) thin films upon 2 MeV electron beam irradiation changes with different doses. The induced changes in the optical properties for Ppy thin films were studied in the visible range 300 to 800 nm at room temperature. The optical band gap of the pristine Ppy was found to be 2.19 e…
The new method of pyridine pyrolysis is created, the some part of pyrolytic soot of which contains onion-similar carbon with high (10-13%) contents of nitrogen (or “pyridine carbon”). Nanoparticles of this “pyridine carbon” are formed only in a gas phase at the expense of reactions of polymerization and polycondensati…
Transparent conducting Al-doped ZnO (AZO) thin films were deposited on soda-lime glass substrates by DC magnetron sputtering with a novel sintered ceramic target, AZOY ® that contains a small amount of Y 2 O 3 in addition to Al 2 O 3 and ZnO. The effect of substrate temperature (T s ) on the structural, electrical and…
