Several methods of decontamination, such as melting, heating with flame, isotopic exchange with gaseous hydrogen, replacement with hydrogen, and thermal desorption under moist gas, were tested on stainless steel, INCONEL®, beryllium, copper, and aluminum bronze contaminated with tritium. The detritiation methods were…
For the DyMnO3 multiferroic with a modulated magnetic structure, switching of its spontaneous electric polarization (P ‖ c axis) near the ferroelectric transition (T < T FE ∼ 20 K) is revealed by measuring the dielectric hysteresis loops. It is found that the coercive field strongly increases as the temperature decrea…
A review of the condition assessment methods of porcelain insulators shows that there is motivation for further improvements particularly regarding applications in distribution systems. Acoustic and high frequency (HF) methods are quite attractive mainly due to better immunity to noise and the relative easiness with w…
Microbially influenced corrosion (MIC) of steel has gained increasing attention in recent years because the damage caused by this process is a significant cost factor for industry. Consequently, inhibition of corrosion and especially the development of corrosion protective films is an important present-day research to…
Highly transparent and conductive B-doped ZnO (BZO) thin films have been prepared by a newly developed vacuum arc plasma evaporation method that provided high-rate film depositions using sintered BZO pellets and fragments. The obtained electrical and optical properties of the deposited BZO thin films were considerably…
In order to clarify the peripheral chain substitution position effect on columnar mesophase and stacking structures, we have synthesized three novel series of discotic liquid crystals (1-3) having octakis(phenoxy)phthalocyaninato copper(II) as a central core and one peripheral chain at the para position (1), meta posi…
In this paper, we describe the effects of ultrasonically preformed cavitation multibubbles in molten metal on both the onset of nucleation and the grain refinement of the solidified metal. Wood's alloy, that is, a bismuth-based quaternary eutectic alloy having a low melting point, was employed in the experiments. It w…
A metal-free phthalocyanine with four pyridyl donor groups, bound through ethylthio ester bridges on the periphery, have been prepared. The pyridine donors were quaternized with iodomethane to a water-soluble tetracationic phthalocyanine. The tetranuclear supramolecular phthalocyanine was prepared by the coordination…
BCC wires macroscopically deformed by axisymmetric elongation (wire drawing) develop an intense <011> fibre texture and exhibit a characteristic non-uniform deformation of the grains evident in transverse sections (grain curling or “Van Gogh sky structure”). The extraordinary grain morphology induced by the <…
Crystal Growth of CdSe Quantum Dots Adsorbed on Nanoparticle, Inverse Opal, and Nanotube TiO2 Photoelectrodes Characterized by Photoacoustic Spectroscopy, Toyoda, Taro, Uehata, Terumasa, Suganuma, Rihito, Tamura, Satoru, Sato, Akira, Yamamoto, Kana, Shen, Qing, Kobayashi, Naoki
Abstract Irradiation hardening and microstructural change of oxide dispersion strengthened (ODS) ferritic steels were investigated by using the ion-irradiation technique. The material used for the present study was K3 (16C-2W-0.3Ti-4.6Al-0.4Y2O3) ODS ferritic steel for the application to Generation IV concept advanced…
It has been shown that the aliovalent substitution of sodium ions for strontium or barium ions in strontium barium niobate relaxor ferroelectric causes a decrease in vacancy content of the samples and a linear variation of unit cell volume with sodium concentration. The variation of c lattice parameter with sodium con…
Mesoporous Ce-Mn-MCM-41 molecular sieves with Si/(Ce+Mn) molar ratios of 43, 61, 79, and 97 were synthesized under hydrothermal conditions using CTMABr (cetyltrimethylammonium bromide) as sur- factant and manganese acetate and cerium sulfate as sources of Mn and Ce, respectively . The Ce 4+ and Mn 3+ ions were coordin…
In the first part of this review, the authors give a survey on the literature of vibrational spectroscopy of phenol, phenol derivatives, and other phenolic componds from the last decade of the last century through today. The classical and modern methods of vibrational spectroscopy are also introduced and a glossary is…
Supramolecular triads composed of free-base porphyrin, fullerene, and ferric porphyrin were constructed by using “covalent-coordinate” binding strategy. For this, a free-base porphyrin was covalently linked to a fullerene entity bearing a pyridine ligand, and was subsequently utilized to coordinate ferric porphyrins b…
In article results calculation of energy the ultrasonic vibrations disseminated in a welding zone of thermoplastic materials in view of reflecting and passing properties of borders welded materials, support and the working tool of oscillatory system are presented. Dependence of time necessary for bonding of materials,…
The breakdown behavior of aluminum alloy (AA)7075 (UNS A97075) samples at various tempers was studied using an in-situ observation system. All under-aged and peak-aged samples showed surface layer dissolution and transient current peaks associated with a breakdown phenomenon at potentials lower than the potential requ…
Nearly 3 decades ago, a dendritic structure was stepwise synthesized for the first time as a new type of molecules with promising applications. During years a huge effort has been devoted to implement the synthetic skills concerning the synthesis of these molecules and especially, new methods for purification and char…
Due to a continuous power density increase, the thermal stresses endured by the electrical insulation of rotating machines are also increasing. However, up to now, most of the characterizations (breakdown voltage, permittivity, loss tangent) are usually carried out in a temperature range which rarely exceeds the therm…
The possibility of modifying the properties of poly(4,4′-oxydiphenylene)pyromellitimide films by introducing into prepolymer solutions nanoparticles of various compositions and structures [hydrosilicate nanoparticles in the form of layered structures (montmorillonite) and nanotubes; carbon nanofibers] was examined. Ne…
