In this paper were defined thermal characteristics (thermal diffusivity up to 2000 °C, heat capacity up to 1250 ° C and thermal conductivity of up to 1250 °C) of oxide nuclear fuel with additives of burnable neutron absorber in the form of (Al,Gd)O 3 . Also for comparison samples UO 2 with gadolinium Gd 2 O 3 and pure…
The influence of stepwise deformation upon the electrical conduction of the AlMg6 aluminum–magnesium alloy is investigated experimentally. It is found that the nucleation and development of single deformation bands causing stepwise deformation increase the specific electric resistance of the alloy on average by 2–3%.…
This study is concerned with the research and development in the field of materials science, leading to the industrial applications especially for the development of materials by moulding process. The purpose of this study was to determine the influence of vanadium on microstructural, mechanical and electrochemical pr…
Production of renewable electricity and hydrogen in biorefinery can add a significant value towards development of a sustainable bioeconomy for the 21st century. Here, we investigate bioelectrochemical systems for conversion of biomass and waste using biological fuel cells and electrolysis cells. The ability to extrac…
The paper examines the impact of the initial state (the presence of impurities, surface preparation), and surface alloying on the kinetics of the oxidation of fuel cladding alloy E110. The studies concluded that the use of ionic polishing instead of traditional chemical polishing helps to reduce the rate of oxidation…
The electronic structures of -phase of solid oxygen (O2)4 are studied within the framework of densityfunctional theory. The intriguing molecule has been known to have magnetic properties at room temperature by applying pressure. Nevertheless, until now there was no evidence of band structure studied in the antiferroma…
Metallic nuclear fuel is a perspective kind of fuel for fast reactors. In this paper we conducted a study of the interaction between uranium-molybdenum alloy and ferritic- martensitic steels with additions of aluminum at a temperature of 700 ° C for 25 hours. The rate constants of the interaction layer growth at 700 °…
Nowadays, the rapid development in portable electronics, load leveling/peak shaving for the power grid and electric automotive, requires significant progress in high voltage and high capacity storage systems [1,2]. Lithium batteries are, to date, the most promising systems that can sustain this demand [3]; they have h…
The application of rate controlled sintering (RCS) technique for fabricating oxide fuel pellets in industrial conditions is investigated. Green pellets of UO 2 (with no additives) which underwent industrial-type compacting were sintered in reducing Ar - 8% H 2 medium using dynamic and isothermal RCS modes with exposur…
Water oxidation is one of the biggest challenges towards establishing a sustainable energy economy based on renewable energy. Non noble metal electrocatalysts can significantly reduce the costs and make usage of electrochemical water splitting on a large scale possible. Those metal oxide catalysts can be an effective…
Nanoparticles of palladium and its oxides are synthesized on carbonic materials via the laser ablation and deposition of metals in electric fields. Studies of the materials show it is possible to control the crystallinity, size, and chemical state of nanoparticles without changing the laser beam parameters.
Recently, many sorts of lithium batteries have been studied such as all solid and lithium-air batteries etc., for EV and ESS applications. Especially, all solid battery is one of the candidates for a large-sized battery in regard of the safety problem. Garnet-type LLZO electrolyte has good advantages with a high ionic…
Rf GD-OES (Radio Frequency Glow Discharge - Optical Emission Spectroscopy) is a technique which can provide a Depth Profile Elemental Composition of coatings and thin films. In the case of the Li ion Battery Electrodes, it is possible to get the variation of all the elements in the organic coating and underneath layer…
Chemical mechanical polishing (CMP) slurries formulated of cerium oxide nanoparticles (CNPs) and polyacrylic acid (PAA) are widely used in shallow trench isolation (STI) application. The critical parameter in slurry formulation is the amount of PAA which determines the extent of its adsorption on CNPs and the excess a…
An approach based on Electrochemical Impedance Spectroscopy (EIS) was formulated and investigated to understand the most efficient fuel conditions for suitable long term operation of a solid oxide fuel cell stack under power generation conditions. The procedure helped to reflect the individual effects of CO/H2 volumet…
The purpose of this study is to develop a forging process of automotive parts that satisfies the deformation characteristics. The analyses of temperature variation and deformation behavior of the material are important to obtain the optimal forging products. The hot compression test was carried out to know formability…
The method of acoustic spectroscopy is used for the first time for investigating the spectra of ultrasonic attenuation in the range of 3–100 MHz on oriented carbon nanotubes in the stabilized aqueous dispersion. The anisotropy of attenuation of ultrasound manifests itself in a significant distinction between the atten…
Recently there has been an increased interest in the development of small molecule electrooxidation catalysts such as (2,2,6,6-tetramethylpiperidin-1-yl)oxyl (TEMPO), for use in the anodic compartment of a biofuel cell. Some TEMPO derivatives are capable of electrochemically oxidizing short chain alcohols and various…
