As part of the Fast Reactor Cycle Technology Development (FaCT) Project, JSFR (Japan Sodium-Cooled Fast Reactor) core design efforts have been made to cope with the transuranic (TRU) fuel compositions expected during the light water reactor (LWR)–to–fast breeder reactor transition period, during which various kinds of…
The influence of preliminary incomplete shape memory (SM) deformation on the generation of reactive stresses in single crystals of the Cu-13.6 wt % Al-4.0 wt % Ni alloy under conditions of constrained SM deformation has been studied. It has been found that, with an increase in the deformation, the value of reactive st…
The described generator produces a wide-aperture flow of charged plasma particles (electrons, positive and negative ions) with a cross-sectional diameter of at least 120 cm, which propagates to a distance of 50 cm or more (depending on the operating mode and the geometric dimensions of the vacuum chamber). The uniform…
below 10% leading to an overall r² of 0.87.This highlights that our present scoring function is a blueprint for integration into general empirical scoring functions, which at present ignore halogen bonding interactions.Hence, recognition of halogen bonding will be implemented soon into protein-ligand docking and scori…
Widespread use of caching provides advantages for users and providers, such as reduced network latency, higher content availability, bandwidth reduction and server load balancing. In Information Centric Networking, the attention is shifted from users to content, which is addressed by its name and not by its location.…
The interface between titanium dioxide and biological solution is relevant for the bioactivity of titanium implants. Adhesion phenomena between inorganic solids are of general interest for mineralization and bone formation processes. Such interfaces are complex systems with many constituents including the hydroxylated…
A technique of covering stainless steel electrodes with a thin galvanic nickel coating containing vanadium-pentoxide particles as inclusions is developed, and regularities of the cathodic evolution of hydrogen on the modified electrodes in 30% KOH solution are studied. The content of vanadium in the surface layer of t…
Spectral luminescent properties of Zn(II) tetraphenylporphyrin (ZnTPP) and its complexes with some amines (methylamine, dimethylamine, trimethylamine, ammonia, and pyridine) are studied experimentally. The absorption and fluorescence spectra and the fluorescence quantum yield of ZnTPP in 1,2-dichloroethane are measure…
This study presents an analysis of various size metal particle waste (MP) influences on Portland cement (PC) paste hydration course, concrete sample structure densification during hardening and physical-mechanical properties. Investigations have shown that MP filler accelerates maximum heat release rate in PC pastes.…
Abstract Directional solidification technique is an important research instrument to study solidification of metals and alloys. In the paper the model [6,7,8] of directional solidification in special Artemis-3 facility was presented. The current work aimed to propose the ease and efficient way in calibrating the facil…
The evolution of the phase composition, nanostructure parameters, and macroscopic stress in soft magnetic Fe95 − x Zr5N x films (prepared by ion-plasma deposition onto quartz substrates) during their annealing has been investigated by X-ray diffraction. During deposition, depending on the N content, either a mixed str…
유체이송 기술은 최근 마이크로 유체시스템 개발에서 핵심문제로 인식되고 있다. 본 논문에서는 외부동력을 사용하지 않고 액적을 이송시킬 수 있는 새로운 개념을 제안하고, 수치해석을 통해 증명하였다. 제안된 장치는 표면을 단순하게 친수성과 소수성 표면의 복합표면으로 구성하는 것이다. 새로운 개념을 입증하기 위한 수치해석은 보존적인 압력기반 유한체적방법에 기초한 비정렬 셀 중심 방법 및 VOF 방법에 체적포착법인 CICSAM을 채용하고 있는 자체개발 코드(PowerCFD)를 사용하였다. 연구결과 본 연구에서 제안된 개념이 마이크로 유체시스템에서 액적이송에 대해 우수한 성능…
The structure of hydroxyapatite plasma coatings on a titanium substrate has been investigated by the X-ray Rietveld method. The hydroxyapatite crystal structure in plasma-deposited samples is characterized by strong distortions of its main element (tetrahedral PO 4 cluster) and coordination calcium polyhedra, as well…
The character of changes in the light-reflection coefficient in the zone of indicator patterns of flaws on a magnetic-field-visualizing film was determined during magnetic testing of ferromagnetic plates. The flaw detection in specimens was performed in an applied field directed in parallel to the inspected surface. E…
Fe2+ doped silica sol was prepared using tetraethoxysilane (TEOS) as precursor, ethanol as solvent, hydrochloric acid as catalyst and aqueous solution of ferrous iron by sol-gel method under the follow condition: [TEO:n [EtO:n [H2=1:6:11, reacted at 70°C for 120 min with stirring. Through characterization of the prepa…
Channel waveguides were written in a fluoroindate bulk glass containing thulium, with a femtosecond laser operating at 800 nm, 100 fs pulses and a repetition rate of 1 kHz. Formation of waveguides occurred for average powers from 1 to 8 mW (corresponding to energies of 1–8 μJ) and scan velocities in the range of 0.1–4…
This paper presented the main objective characterization of cracks in welded joints of ferritic steels, since these are considered one of the most serious types of discontinuities in welds of these steels. These discontinuities are formed when tensile stresses are developed in a fragile material, unable to plastically…
With the certification of PAS 55 in 2013, there is a need for Tenaga Nasional Berhad (TNB), an electric utility company in Malaysia to further enhance the systematic assessment methods to evaluate asset performance in order to sustain the certification. Among the vital assets in TNB are the distribution transformers,…
Improved power conversion efficiency (PCE) of flexible polymer bulk heterojunction solar cells based on regioregular poly(3-hexylthiophene) (P3HT) and methanofullerene [6,6]-phenyl C61-butyric acid methyl ester blends with a non-thermal annealing active layer have been obtained by using 1,2,4-trichlorobenzene as the s…
Coercive force H c of a minor hysteresis loop of steel is shown to be determined by the parameters of the saturation hysteresis loop. The sensitivity of H c to the structure- and phase-sensitive parameters of a metal is analyzed, a technique for an effective use of the results of measuring H c in magnetic structural a…
