A composite right/left-handed (CRLH) transmission line with demultiplexing property is proposed towards short-range functional wireless interconnects. The CRLH line is designed by analyzing dispersion relation of the microstrip line having a split-ring and a double-stub structure to realize frequency selective propert…
In Korea, newly advanced installation method of containment liner plates was developed and adopted for the construction of Shin Wolsong Unit 2 NPP. The key method of the new installation method of concrete liner plates was using a three-stage-based modularization (lifting of 3 plate ring module) instead of using conve…
Coupling between pressurized gas sorption and tensile behavior was studied in a polyethylene (PE). Tensile and creep tests into hydrogen (30 bars) and nitrogen (30 bars) atmosphere were compared to experiments into atmospheric air. Gaseous environment was shown to have noticeable influence neither on the modulus / yie…
The mechanical behaviors of solid-liquid two-phase materials are affected by environmental conditions because of the moist structure of the materials. Therefore, material tests to investigate the solid-liquid interactions in these materials should be conducted by considering various conditions such as multiaxial stres…
Collective motion, such as flocks of birds or shoals of fish, is ubiquitous in nature. Physicists describe such fundamentally out-of-equilibrium phenomena with the new conceptual background of polar active matter. It is a system of polar particles, i.e. enable to use provided energy in order to move in their own direc…
The purpose of this research is to clarify the requirements for the high output power SMA engine. The main results obtained by this research are as follows. In order to increase the output power of the SMA engine, it is necessary to make the radius of the high temperature wheel as small as possible, while the minimum…
Analysis of recent experimental impedance spectra and polarization curves of nickel/yttria-stabilized zirconia (Ni/YSZ) patterned anode of a solid oxide fuel cell (SOFC) are used to determine the limiting steps in CO electrochemical oxidation kinetics. A comprehensive 1D model is proposed for the prediction of the ste…
The composite films of amorphous and nanocrystalline Fe73.5Cu1Nb3Si13.5B9powders/butyl rubber were prepared by pressing in the mold to shape. The piezomagnetic properties of composite films were studied in the temperature range of 20-50 Celsius degree with theshielding properties in the frequency band (30kHz-6000MHz)…
Fatigue strength is one of the most important mechanical properties. Durability and reliability of car parts are often defined by their fatigue strength, since most of them are loaded with dynamic, repeating or variable loads and the main type of failure is metal fatigue. Various surface hardening methods have a huge…
The magnetic and transport properties of bulk polycrystalline samples of double perovskite SrLaVMoO6 have been investigated. Structural analyses have shown that the samples are almost in single phase. Magnetization measurements have indicated that the SrLaVMoO6 compound exhibits a cusp at 125K, which is attributable t…
Haciendo uso de la quimica sol-gel, se han preparado ortofosfatos de composicion LiTi_(2)(PO_(4))_(3) y Li_(1.05)(Cr/Fe)_(0.05)Ti_(1.95)(PO_(4))_(3) a temperaturas moderadas mediante el metodo Pechini. Estas fases han sido caracterizadas estructural y microestructuralmente por difraccion de rayos X de polvo y microsco…
Mesoporous silica nanotubes (SNTs) and amine-functionalized SNTs (MSNTs) have been successfully synthesized and subsequently functionalized with blue fluorescent CdS quantum dots. The comparative study for several kinds of nanotube materials for the storage of ibuprofen indicated that the drug loading amount in CdS-in…
In this work we give a phenomenological picture about the properties of the laser interaction with V2O5 single crystals. Our experiments show that the damaged region of the crystal surface is surrounded by a humped surface. The inner part of the examined region is covered by amorphous V2O5 and the outer part of this r…
We report on soliton formation in laserwritten two-dimensional binary waveguide lattices. Even for small index contrasts between the sublattices, soliton intensity profiles and power thresholds strongly depend on whether “deep” or “shallow” channels are excited.
Molecular arrangement and morphology of Langmuir-Blodgett (LB) films for the several organo-modified montmorillonites were investigated by out-of plane and in-plane X-ray diffraction (XRD), and atomic force microscopy (AFM). These organo-modified montmorillonites are formed by cation exchange reaction with quaternary…
Based on the Mie scattering theory and the low density approximation,anderson localization of GaP photonic crystal is calculated theoretically and the factors are analyzed which influence on the anderson localization parameter.The results show that the photonic crystal of GaP has anderson localization phenomenon in mi…
By using a tensor method, spectral changes of a focused electromagnetic Gaussian Schell-model (EGSM) beam with twist phase. Our results show that the spectral shift of twisted EGSM beam is closely related to the degree of polarization, twist phase and correlation coe-cients of the initial beam.
A code has been developed with proper models for the thermal-hydraulic simulation of research reactors, and the accident of loss of offsite power of CARR (the China Advanced Research Reactor) has been analyzed. It is found that the transient can be departed into four parts with two peaks, and at last terminated to a n…
This paper discusses the possibility of realizing improvements in magnetic properties of non-oriented electrical steel sheets. In such sheets, a random {100} texture can increase flux densities and decrease iron losses, and the increase in flux density at 5000 A/m (B50) may be over 0.2 T, while decrease ratio of iron…
The utility of microwave heating and microwave generating of plasma as a synthetic technique toward the synthesis of Sb2Te3is reported. The solid-state microwave synthetic method was studied the effects of irradiation times and cycles, and molar ratio of Sb:Te at a 900 W irradiated microwave power in order to determin…
