The dielectric properties of Ag/ZnO composite material are investigated and a strong low-frequency dispersion phenomenon is found. The experimental results are systematically studied in the frequency range of 0.1—107 Hz and in the temperature range of 173—473 K. By means of normalization of conductivity, it is found t…
Soda and kraft pulping experiments were carried out in order to investigate the pulping characteristics of bamboo grown in Vietnam. The merit of kraft pulping was not observed for bamboo pulping from the viewpoint of delignification and screened pulp yield. The improvements of delignification during soda and kraft pul…
The growth of helium cluster in titanium crystals at room temperature has been simulated detailedly by means of molecular dynamics. The mechanism of helium cluster growth in metal materials has been investigated from the viewpoint of energy. It is found that, as the helium cluster grows, dislocation loops are formed a…
Rhodium adsorption on （6, 6） single-walled carbon nanotubes （SWCNTs） was systematically investigated by density functional theory （DFT）. According to the analysis of adsorption configurations and adsorption energies, it is found that the most stable configurations are I-H1, I-H2, O-H1, O-H2 and O-B1. The adsorption en…
市販の水性6種類及び油性2種類の木材保護塗料で塗装されたスギ心材を, 南向き傾斜45度の条件で24ヶ月間の屋外暴露試験に供し, 塗装面の変色, 表面欠陥率, 撥水度の変化を評価した。また, 木目の隠ぺいの程度に関する因子として, 塗装面の早・晩材のコントラストを評価し, 耐候性能との関係を考察した。水性塗料の耐候性能は, 製品間で大きく異なった。24ヶ月後の色差 (ΔE *ab) は, 水性塗料では10～50, 油性塗料では10～20の範囲に分布した。色差の小さい水性塗料は, 表面欠陥率でも油性と同様に比較的低い値を示した。撥水度は, 油性塗料では18ヶ月後まで80%を上回ったが, 水性塗料の多くはそれまでに80%を下回った。変色…
Nano-crystalline silicon films were prepared from SiH4 diluted with hydrogen by plasma enhanced chemical vapor deposition at a pressure of 230 Pa. The effect of hydrogen dilution on their growth rate and crystalline properties were investigated. The experimental results indicate that the crystalline fraction and grain…
Description Sixteen peer-reviewed papers provide a global review of the latest research in small volume specimen testing. These papers cover: • Specimen Size Limitations in J-R Curve Testing • Fracture Toughness Evaluation • Application of Subsize Specimens for Re-Irradiation Embrittlement Monitoring of First Generati…
In this work we present the influence of atomic disorder on the electronic and magnetic properties of Ni2MnGa1-xGex and Ni2MnSn Heusler alloys.Ab initio band calculations were performed for the experimental lattice parameters.We applied SPR-KKR-CPA methods in the local spin density approximation.
In this paper, we describe the preparation of glass ceramics in the Ga2S3 - GeS2 - CsCl system Visible and infrared transmitting glass ceramics were reproducibly obtained by appropriated heat treatment of the base glass Crystals with controllable size of about 40 nm were homogeneously generated in the glassy matrix X-…
Water adsorptions on TiO2-terminated SrTiO3（001） surfaces at four kinds of coverages （0.25 monolayer（ML），0.5ML，0.75ML and 1ML） are investigatedby by using density functional theory calculations. Molecular and dissociative adsorptions of water are comparatively investigated. The nudged elastic band method is employed t…
This study aims to evaluate the resistance of three types of particleboard panel to biodeterioration, two of which bonded with synthetic resins and one bonded with PVC plastic. Composite panels were made using sugar cane straw particles as raw material which were bonded together with urea-formaldehyde (UF), tannin-for…
High-quality single crystal of a novel cerium silicide CeRh 3 Si 2 , crystallizing with the orthorhombic ErRh 3 Si 2type structure, was grown by the Czochralski pulling method and studied by means of specific heat measurements.The antiferromagnetic ordering of the compound manifests itself as a pronounced lambda-shape…

The th…
The electron field emission performance of CNT doped with one nitrogen atom in different atomic layers and adsorbed with H2O molecules of different numbers was investigated through the first-principles calculations. The results show that the structure of the systems investigated is stable. The margin of the density of…
In constructing a review from such a huge body of published science, editors must make many choices, none of which would have been possible without Sci-Finder® (i.e., Chemical Abstracts) of which we have made optimal use. Details like the organization, selection of articles, and the brevity of the abstracts is our fau…
Values of DHC rates in Zr alloys are sensitive to measurement procedures. A standard method has been developed at the laboratories of AECL and evaluated in a round-robin involving ten IAEA member states. Two test materials were used—Zr-2.5Nb pressure tubes in the cold-worked (CANDU™) and heat-treated (RBMK) conditions…
