As a key component for a future power substation system entirely consisting of solid insulating materials, a special connection system between different pieces of power equipment has to be developed. A soft dielectric such as silicone rubber and a hard one such as epoxy resin are to be used for this connection. This p…
We consider the imbibition of a liquid droplet into a deformable porous substrate. The liquid in the droplet is imbibed due to capillary suction in an initially dry and undeformed substrate. Deformation of the substrate occurs as the liquid fills the pore space. In our model, a pressure gradient in the liquid across t…
Hydrogen distributions around non-metallic inclusions in steels are successfully characterized with high-resolution tritium autoradiography. The autoradiographs show that hydrogen accumulation characteristics around the inclusions depend on types of the inclusions. In the case of MnS, hydrogen was inhomogeneously dist…
The behavior of fission gas in all major types of nuclear fuel has been reviewed with an emphasis on more recently discovered aspects. It is proposed that the behavior of fission gas can be classified in a number of characteristic types that occur at a high or low operating temperature, and/or at high or low fissile b…
Transport, thermal and magnetic measurements have been carried out on (Pr1-ySmy)1-xCaxCoO3. The system exhibits a structural phase transition accompanied by the spin state change from the intermediate spin (IS) state to the low spin (LS) state with decreasing temperature T. We have constructed a T-y phase diagram for…
Stark sublevels of multiplets of the $4{f}^{5}$ electronic shell ion have been determined and the Judd-Ofelt intensity parameters have been calculated. Decay curves of the luminescence originating with the $^{4}G_{5∕2}$ multiplet in ${\mathrm{K}}_{5}{\mathrm{Li}}_{2}{\mathrm{La}}_{1\ensuremath{-}x}{\mathrm{Sm}}_{x}{\m…
The conjugates of some kinds of anticancer agents with chitin and chitosan derivatives display good anticancer effects with a decrease in the adverse effects of the original drug due to a predominant distribution into the cancer and a gradual release of free drug from the conjugates. For instance, doxifluridine and 1-…
This paper presents geometric and algebraic algorithms and relevant optimizing operators for 3D computer modelling of yarns in fabric. New algorithms and approaches are successfully employed to create more realistic and flexible geometry models with consideration of the differential and topological structure of yarns.…
We studied the electrical properties of 20- and 50-nm-thick Ge 2 Sb 2 Te 5 and AgInSbTe films for nonvolatile lateral transistor memory devices. Both kinds of thin films were prepared as film samples and device samples which were then annealed at temperatures from 140 to 415°C. It is known that crystal size can be eff…
Conductive transparent In 2 O 3 thin films with (222)-preferred orientation were prepared by rapid thermal oxidation (RTO) in static air of indium thin films at condition 200°C/30 s. Detailed structural, electrical, and optical characteristics of the film are presented. The data are interpreted to give a direct bandga…
3D hydrocode simulation on the perforation and penetration of reinforced concrete target has been performed. The simulation aims to examine the influence of the following constitutive models for concrete on a projectile's residual velocity: (1) constant-yield strength (2) pressure-dependent yield strength (3) pressure…
The polar order and its switching characteristics have been investigated by means of optical second-harmonic generation interferometry in a compound N, N'-bis(3,4,5-trialkoxylphenyl)urea (R=n- C16 H33) being connected by intermolecular hydrogen bondings to form a columnar liquid crystalline phase. The polar structure…
The protonation of a simple meso-tetraphenylporphyrin in an organic-aqueous system was found to be induced by the counteranions. During the process of protonation, the counteranion of the proton sources binds with the porphyrin core and thus promotes the complexation of the porphyrin and protons. The interaction of po…
Extended abstract of a paper presented at Microscopy and Microanalysis 2005 in Honolulu, Hawaii, USA, July 31--August 4, 2005
The application of pulsed ultrasound for the degradation of the nonvolatile surfactants sodium 4-octylbenzene sulfonate (OBS) and sodium dodecylbenzenesulfonate (DBS) was investigated at a frequency of 354 kHz. By comparing the degradation rate constants with those of continuous wave (CW) ultrasound, observed pulse en…
The nanoclay, montmorillonite, and some modified nanoclays were used as sorbents for nonionic, anionic and cationic dyes. From the sorption differences among the different dye and clay structures, both chemical and morphological, the sorption forces that played important roles were identified. The nanoclay could easil…
The influence of high electrical fields on water treeing, electrical treeing, relaxation, conductivity and charge mobility in various polymers is reviewed within the context of a molecular model. The real value of the AC field acting on water trees is questioned and it is shown that the strain induced by very large fi…
Phase transitions in binary molybdates and tungstates of mono- and trivalent elements, as well as some of their physical properties are reviewed with a special attention to ferroelastic and ferroelectric behavior. There are many compounds with phase transitions of the displacement type and reconstructive ones. The aut…
An optical spectrometer has been integrated into a JEOL 8900R electron microprobe, which allows simultaneous collection of light, X-ray, and electron signals. The cathodoluminescence signal is collected from a monocular eyepiece, which is integrated into the electron optics of the electron microprobe. The optical acqu…
Abstract— LCD TVs have dramatically improved in performance during the last 2 years. At the same time, the sale prices decreased by more than 50%. Together with the introduction of digital terrestrial broadcasting, this resulted in increasing sales of LCD TVs. This paper gives an overview of the main liquid‐crystal di…
