This paper presents a deterministic performance assessment for spent fuel from deep-burn modular high-temperature reactors (DBMHRs) in the proposed Yucca Mountain repository. Typical DBMHR designs utilize fuel elements manufactured from graphite. The fuel itself is made of TRISO particles containing the fissile materi…
To suppress the thermal decomposition and to stabilize the crystal structure of Gd 3 Al 5 O 12 (GdAG) garnet, doping GdAG with smaller Ln 3+ (Ln=Tb, Dy, Ho, Er, Tm, Yb, Lu, and Y, respectively) to form (Gd,Ln)AG solid solutions was proposed in work. Carbonate precursors of (Gd,Ln)AG with an approximate composition of…
Influence of the short time external polarization of silver electrode contacted Ce0.8Sm0.2O1.9 electrolyte was studied. Silver is moving along the Ce0.8Sm0.2O1.9 surface during the -0.5 V cathodic polarization at 600°C. It caused both the increase of the electrode - electrolyte contact area and the triple phase bounda…
We have developed a new computational method to efficiently estimate capillary interactions among many moving particles at a free surface. A novelty of the method is the immersed free surface (IFS) model that transforms the surface tension exerted on a three-phase contact line on a particle surface into the surface te…
In this Letter, we propose an optical configuration of a four-domain vertical-alignment (VA) liquid-crystal (LC) cell, which can improve the γ-curve distortion by using a pair of patterned A plates, without any change in cell structure. In order to find the optimal parameter value of the patterned A film, we calculate…
Thick porous Si layers locally formed on a low resistivity Si wafer were studied for their application in on-chip RF device integration. A comparison was made between the above porous Si substrate and trap-rich high resistivity Si (trap-rich HR Si), which constitutes a state-of-the-art substrate for RF integration, by…
In this work thermal conduction in one-dimensional (1D) chains of anharmonic oscillators are studied using computer simulation. The temperature profile, heat flux and thermal conductivity are investigated for chain length N = 100, 200, 400, 800 and 1600. In the computer simulation anharmonicity is introduced due to Fe…
Abstract A simple and fast method was developed to fabricate pH‐responsive microcapsules. After the copolymerization of N ‐isopropylacrylamide (NIPAAm), methacrylic acid (MAA), and a crosslinker, poly(ethylene glycol) diacrylate, at 65°C in the presence of sacrificial CaCO 3 microparticles, hollow microcapsules were a…
Effect of CO2 saturation on the corrosion behaviour of AZ31B magnesium alloy in the presence of different concentrations of Na3PO4 solution was investigated by open circuit potential (OCP), potentiodynamic polarization and electrochemical impedance spectroscopy (EIS). As it was expected, in solution without CO2 the co…
An optimum configuration of Ag–Au and Cu–Au core–shell nanorods is proposed for biological sensing applications. The analysis of surface plasmon resonance (SPR) in metal nanoparticles by means of extended Gans theory reveals that the sensitivity of the nanorod is controlled by three main factors: composition, aspect r…
The electronic circular dichroism (ECD) and UV-visible absorption (UV-vis) spectra of Strandberg-type polyoxometalates (POMs) (R, R)-[(R*PO3)2M5O15](2-) (R* = CH3CH(NH3), (M = Mo, W)) have been explored using the time-dependent density functional theory (TDDFT) method. It demonstrates that the absolute configurations…
We show that a commercial microwave oven can be used after growth to increase alignment of carbon nanotubes (CNTs) and reduce their resistance as thermal and electrical interface materials. Forests of multiwall CNTs were grown directly on both sides of aluminum foils by thermal chemical vapor deposition (CVD) and subs…
Etching of indium tin oxide (ITO) thin films in high density chlorine plasmas is studied, with the goal of increasing the etching selectivity to photoresist. The ITO etching rate increases with ethylene addition, but is not affected by BCl3 addition. ITO exhibits a threshold energy for ion etching, whereas the photore…
In power system, the consistent power supply plays a vital role in generation, transmission and distribution. It is necessary to aid uninterrupted power supply by continuous monitoring of power apparatus. Mainly insulators are the integral part of the power system. Among them composite insulators are essential for the…
The basic possibility is studied for producing biocompatible oxide coatings on periosteal osteofixation devices from stainless steel using the air-thermal oxidation method. The properties of the coatings are studied at different temperature modes of oxidation. Steel osteofixation devices with air-thermal oxide coating…
Thermodynamics of (001) epitaxial ferroelectric films completely relaxed due to the formation of elastic domains with a three-domain architecture is presented. The polydomain structure and electromechanical response of such films are analyzed for two cases corresponding to immobile and mobile elastic domain walls. It…
Some indole derivatives are investigated as corrosion inhibitors for nickel in 0.5 M HCl solution using potentiodynamic polarization and electrochemical impedance spectroscopy (EIS) techniques. A significant decrease in the corrosion rate of nickel was observed in the presence of investigated indole derivatives. Poten…
In this paper, Ag-Zn alloy are dealloyed in 0.1M H2SO4 at a low temperature (2°C) to fabricate nanoporous silver and the dealloying kinetics has been systematically investigated. Comparison of the polarization curve of Ag-Zn alloy in 0.1M H2SO4 at room temperature and 2°C shows that lowering temperature can significan…
In the present work, we have synthesized ZnO nanostructures by sol-gel method in air at different selected sintering temperatures ranging from room temperature to 400 0 C and studied their structural, optical and ferroelectric properties. The synthesized samples are characterized by X-ray diffractrometer for structura…
In this study, a tempered martensitic matrix was obtained in a low carbon steel, by applying austenization, quenching and tempering heat treatments. After austenization at 1000°C for 30 minutes, steel samples were quenched in water and then tempered at 200, 540 and 600°C for 30 minutes. Hardness measurements were done…
