Two kinds of radiation-induced structural changes were observed in U-Mo/Al dispersion fuel: radiation-induced recrystallization of U-Mo fuel particles and radiation-induced amorphization of interaction products. During irradiation, U-Mo fuel showed refined microstructures of submicron-size grains due to dynamic recrys…
Abstract Dinuclear and tetranuclear copper(II) complexes with a ligand bearing phthalocyanine and Schiff-base coordination sites were prepared and characterized. The dinuclear complex has two copper(II) phthalocyanine units linked by 2,6-diiminomethyl-4-methylphenol. The imino nitrogen (Schiff-base) coordinates to two…
The novel coupling recrystallization model is proposed in this study. First, the deformation microstructure was simulated by the finite element method based on the strain gradient crystal plasticity theory. The calculated dislocation density and crystal orientation were transferred to the recrystallization phase-field…
Estudou-se a evolução geoquímica e mineralógica em três perfis distintos de alteração de rochas serpentinizadas que ocorrem nas imediações dos municípios de Alpinópolis e Fortaleza de Minas, no sudoeste do Estado de Minas Gerais, sob regimes de umidade e de temperatura údico e térmico, respectivamente. Nas condições a…
Pizgrischite, (Cu,Fe)Cu14PbBi17S35, is a new mineral species named after the type locality, Piz Grisch Mountain, Val Ferrera, Graubunden, Switzerland. This sulfosalt occurs as thin, striated, metallic lead-grey blades measuring up to I cm in length, embedded in quartz and associated with tetrahedrite, chalcopyrite, py…
One of the critical issues of Flibe/V-alloy blanket with REDOX control by Be is a large tritium inventory in V-alloy structures. Among the possible solutions to this issue would be to control REDOX not by Be but by addition of MoF6 or WF6 enhancing the reaction from T2 to TF. The present study investigated feasibility…
The present paper is to describe the behavior of tritium in Flibe as a self-cooled liquid blanket of a fusion reactor quantitatively. In order to avoid the generation of corrosive TF, Flibe is maintained under reduction atmosphere to transform TF to T2 to keep a faster reaction rate compared with a residence time in a…
Partial discharge (PD) measurement is an established condition monitoring technique used to assess the deterioration of high voltage insulation systems such as power transformers and gas-insulated switchgear. Two popular monitoring techniques employ radiated RF measurements and conventional apparent charge measurement…
In order to design an efficient air-conditioning system, the specifics of the transient thermal and physiological responses of a human body to the hygrothermal environment should be taken into account. This response will strongly depend on the behavior of heat and moisture transport, and moisture accumulation in the c…
Variable Frequency Microwave (VFM) technology has reduced the full cure temperatures of 350degC for PI films to as low as 175degC with only one hour cycle times. PBO films, with standard cure temperatures of 350-380degC, can be fully cured at 185-200degC in one hour with VFM. The resulting VFM cured film properties ar…
Abstract It is known that for painted metals the presence of hydrosoluble species within the layer of atmospheric corrosion products, mainly chlorides and sulphates, beneath the coating promotes osmotic blistering and underfilm metallic corrosion when the concentration of the soluble salts exceeds a critical level. Ho…
Miessiite, a new mineral species of ideal composition Pd11Te2Se2, is cubic, space group Fd 3 m (#227), a 12.448(2) A, V 1929.0 (4) A3, Z = 8. The strongest six lines of the X-ray powder-diffraction pattern [ d in A(I)( hkl )] are: 2.395(80)(511,333), 2.197(100)(440), 1.875(25)(622), 1.555(25)(800), 1.305(25)(931) and…
Abstract Two sets of water‐soluble poly(phenylene vinylene)s were synthesized and their optical properties were studied. The aqueous solubility of all these polymers is rendered by pendant sulfonate groups. One set of polymers (polymer I series) contains, in addition to the sulfonate pendants, dimethoxy substituents,…
Abstract In this study, the Taguchi method, a powerful tool to design optimization for quality, is used to find the optimal process parameters of pulse cathodic protection system for the calcareous deposits' formation. An orthogonal array, main effect and the signal‐to‐noise (S/N) ratio are employed to investigate the…

In this paper, a detailed analysis of the dispersion characteristics of metamaterial transmission lines, based on the lumped element T-circuit model is carried out. One of the main relevant characteristics of these artificial lines is the possibility to tailor the phase response. This leads to unique properties which…
Polymer stabilization (PS), in which mesogenic monomers doped in a liquid crystal (LC) medium are photocured by UV light, is an attractive technique because the physical property of LCs can be improved and furthermore new characteristics may arise. In this study, we have investigated the effects of polymer doping on t…
Abstract Charged nano‐colloidal particles self‐assemble and display ordered arrays or other structures at liquid interfaces. We used Monte Carlo (MC) simulations to examine the effect of long‐range repulsive collective inter‐particle interactions on structural—transitions from liquid‐like to crystal‐like. We used the…
This article is part of an extended study concerning the reactivity of acetylenic systems at high pressure and aims to the investigation of the high pressure synthesis and stabilization of polyacetylenic chains. The data for diphenylacetylene (DPA) are interpreted by establishing a comparison with the results obtained…
