La(Fe,Mn,Si)13Hx-based intermetallic compounds with field-induced first-order magnetic phase transition are one of the most promising materials for application in active magnetic refrigerators (AMR).
In this work there have been studied the processes of co-deposition and layer-by-layer electrochemical deposition of tin-silver alloys of the given composition with near-eutectic and peritectic content of components. To predict the thermal stability of electrochemical deposition of binary systems there have been conducted the thermal research in characteristics of the electrolytic alloys obtained...
A strategy for the selective formation of a pore sealing layer on mesoporous low-k applicable for a Cu dual damascene interconnection process is herein proposed. An ultra-thin, adhesive, and conformal pore sealing layer was formed on mesoporous low-k by spin coating macromolecules. The pore sealant on the Cu surface was selectively decomposed with the help of Cu2O induced oxidization. This selective...
The cupric oxide (CuO) thin films are promising materials in gas sensor applications. The CuO exhibits the highest sensitivity for hydrogen sulfide, but it may be also used as a sensor for carbon monoxide or nitrogen dioxide. The sensitivity and long-term stability are critical issues in gas sensor applications. The authors present the results of investigation on nano-thin film of CuO and CuO doped...
The pellet of Aspergillus oryzae CICC 2026 was found to exhibit glutamate decarboxylase activity, and γ-aminobutyric acid was testified by paper chromatography. Its biochemical and kinetic properties were characterized. The results showed the pellet did not accumulate γ-aminobutyric acid (GABA) in the fermentation broth, but catalyzed the α-decarboxylation of MSG to GABA...
Nucleotide sequences of the 16S rRNA gene of Thermobifida (formerly Thermomonospora) Q-0 was analyzed by MEGA v.3, and the phylogenetic tree showed the relationship between different strains in Thermobifida genus. A carboxymethyl cellulase I (CMCase I) was purified by fractional ammonium sulphate precipitation and ion exchange chromatography on DEAE-Sephadex. The enzyme showed the highest activity...
Since the very beginning of the flash memory era, the market has been dominated by the floating gate technology. However, as floating gate flash continues along a very steep scaling path, more and more barriers start to appear, limiting further scaling possibilities of the technology. At the same time, other concepts are preparing to take over. This paper concentrates on the prospect of high-k materials...
Simple ring-oscillator circuit has been used to estimate the degradation in circuit performance due to negative bias temperature instability (NBTI) effect but it fails to isolate the degradation from the NBTI for PMOS and the positive bias temperature instability (PBTI) for NMOS in high-K dielectric/metal gate CMOS technology. In this paper, we propose new circuit structures which monitor the NBTI...
A new type of unsaturated poly (ester-imide) Viz Phthalic anhydride-ethylene glycol-diethylene glycol - maleic anhydride -urea was prepared by meltpolycondensation. The copolymer was characterized by FT-IR, gel permeation chromatography (GPC) and thermal gravimetric analysis (TGA). Viscosity of the unsaturated poly (ester-imide) was measured with a Ubbelohde viscometer. The molecular structure of...
ldquoDevelopment for advanced thermoelectric conversion systemsrdquo supported by the new energy and industrial technology development organization (NEDO) has been successfully completed as one of the Japanese national energy conservation projects. Three types of the cascaded thermoelectric modules operating up to 850 K in high electrode temperature and two types of Bi-Te thermoelectric modules operating...
Alkaline metal (AM) atoms filled CoSb3 skutterudites are synthesized by melting method and sintered by spark plasma sintering. The maximal filling fraction or filling fraction limit (FFL) of AM (AM=Li, Na, K, Cs) in CoSb3 are estimated experimentally and show good agreement with our previous calculations based on density functional method. The effect of thermodynamics properties on FFL, crystallographic...
