Summary form only given. A SLot-excited ANtenna (SLAN) long racetrack ECR plasma source was newly designed and fabricated. The source can be utilized for roll-to-roll plasma processing such as thin film encapsulation of large-area OLED (organic light emitting diode) panel and functioning or modification of fabric surf…
Dispersion properties of a rectangular metallic waveguide periodically loaded with dielectric resonators (DRs) are investigated both theoretically and by full-wave simulations. Forward and backward wave propagation has been observed in the waveguide at below cut-off frequencies for the fundamental TE10 mode, when the…
As the go as the vigorous development of Chinese nuclear power industry, nuclear power technology is increasingly mature. During Nuclear power plant construction preparation period, a large number of production materials need to be standardized and need professional management, which are still needing to be solved. Th…
In this study, we have coated the inner surface of YSZ channel using LSM powder ink through depressurization process for making the cathode of a stacked planar-type SOFC module. To coat the surface of YSZ channel uniformly, we tried to find the optimum manufacturing condition for LSM ink. We used four different disper…
This paper presents a hybrid method for fast analysis of electromagnetic (EM) scattering from large-scale aperiodic structures (e.g., Penrose and Danzer tilings), which integrates the characteristic basis function method (CBFM) and the adaptive integral method (AIM). The CBFs defined on the macro block facilitate a su…
The optical response of irregular spherical nanoclusters (NCs) are studied by Monte Carlo simulations. Deviations from nominal arrangements are considered by introducing either randomly variable sizes of the constituent particles or random displacements of particle locations around the NC core. The impact of disorder…
The creation of possible local defects on metal-oxide surfaces due to irradiation with a high-energy proton beam was investigated by using a series of gas adsorption isotherms for methane (CH 4 ) on a MgO powder surface. After a MgO powder surface having only a (100) surface had been irradiated with a 35-MeV proton be…

The offshore deep and ultra deep water explorations summed to the distant points of the Brazilian coast bring to national industry important technological challenges. Considering production and transportation need of large volumes of natural gas and oil in a safe condition from offshore installations, the use of large…
The oxidation resistance of FeCrNi heat-resisting steel at 1150°C and 1200°C is analyzed and studied using XRD, SEM and EDS techniques. The results show that the oxidation resistance of the heat-resisting steel is improved remarkably after adding yttrium. The value of oxidation rate of experimental Sample 1 (without a…

In this study, the covered yarn, composed of stainless steel wires as the core and bamboo charcoal roving as the sheath, is made on a ring spinning machine and then knitted into bamboo charcoal/stainless steel fabric by an automatic 14-gauge horizontal knitting machine. According to the test results, both far infrared…
La2/3Sr4/3MnO3 (LSMO) can exhibit anisotropic electrical transport properties in bulk crystals. Artificial layered heterostructures offer the possibility of confining magnetic moments to two-dimensional sheets and increasing the anisotropy compared to bulk crystals. As shown by Shah et al. (pp. 1322–1327), an LSMO cat…
Field emission properties of CNTs(carbon nanotubes) have been investigated in the various field, such as flat panel display and x-ray sources. Especially, the x-ray tube which fabricated using the CNTs can be operated with low power consumption compare with filament-based x-ray tubes. The cold cathode - CNTs- can be o…
Summary form only given. Field emission display (FED) has advatanges in brightness, power consumption, color rendition, response time and operating temperature range. Early prototypes of triode-structured FED using Spindt-cathode were expensive to manufacture in large area. Using self-assembled one-dimensional nanomat…
The problem of determining the loading conditions under which the maximum softening of materials is attained with minimal fracture energy consumption is posed in many practical applications (in building, explosion, drilling, grinding, metal processing by cutting, domestic and industrial waste processing, food industry…
Commercially available magnesium alloy is extensively used in structural engineering components although, like many magnesium-based materials, it suffers from poor corrosion resistance, particularly in moist environments, which limit wider application. Previously, by reducing the contact area of metal substrate with s…

Based on the Pauling’s nature of chemical bond, the valence electron structures of diamond and c-BN crystals have been constructed. Then the relationship between covalent bond and glide plane system is analyzed. The results show that the hardness of diamond and c-BN is correlated to the covalent electron structure and…
Graphene film on nickel substrate is synthesized by using thermal chemical vapor deposition method. The field emission characteristics of the graphene film are measured. The turn-on field of 6.4 V/μm and the emission current as large as 1.5 mA is achieved. The current stability of graphene film is very good with fluct…
