Transparent Sr Li B 9 O 15 (SLBO) glasses were fabricated via the conventional melt-quenching technique. X-ray powder diffraction and differential thermal analysis carried out on the as-quenched samples confirmed their amorphous and glassy nature, respectively. The dielectric constants in the 100 Hz to 10 MHz frequenc…
Lithium was electroplated on a fresh magnesium surface.The deposit was tested as a negative electrode in a cell containing LiFePO 4 as a positive electrode.The reactions that took place on charging the cell were total conversion of phospholivine into a heterosite structure and lithium deposition onto Li͑Mg͒.On dischar…
Systemes hydrodynamiques permettant l’evaluation de l’encrassement des surfaces, de l’adherence des souillures et de leur nettoyage en laboratoire. Cinq systemes hydrodynamiques sont presentes dans cette synthese bibliographique : la cellule a plaques paralleles, le jet impactant, la cellule a flux radial, le disque r…
Shear deformation can induce normal stress or hydrostatic stress in metallic glasses [Nature Mater. 2 (2003) 449, Intermetallics 14 (2006) 1033]. We perform the bulk deformation of three-dimensional Cu 46 Zr 54 metallic glass (MG) and Cu single crystal model systems using molecular dynamics simulation. The results ind…
The cobalt carbonyl nitrosyls Co(NO)(CO)n (n = 4, 3, 2, 1) and Co2(NO)2(CO)n (n = 5, 4, 3, 2) have been studied by density functional theory. The lowest energy structures for the mononuclear derivatives Co(NO)(CO)n (n = 3, 2, 1) parallel those of the corresponding isoelectronic Ni(CO)n+1 derivatives. In addition, a th…
Six hundred thousand tons of beer lees are discharged annually in Japanese breweries. It is well known that purine compounds are one of substances which cause the gout and beer especially contains a lot of purine compounds such as adenosine, adenosine 5’-phosphate and so on, compared with the other alcoholic drinks. T…
Effect of composition of a monomers mixture on the kinetics of radical polymerization in solution of tetrafluoroethylene with perfluoro(3,6-dioxa-4-methyl-7-octene)sulfonyl fluoride is studied.
This research was conducted to investigate the suitability of utilizing hazelnut (Cory/us avellana L.) husk along with European Black Pine (Pinus nigra Arnold) chips to produce general purpose particleboards. Panels with a target density of 0.70 g/cm3 were manufactured using 0,10, 20,30,40,50 and 100 % husk in the mix…
Polyethylene-MMT nanocomposites were prepared by in situ polymerization methodology using TpMs*TiCl3 (1) intercalated into the gallery of Cloisite® 30B (C30B) using methylaluminoxane (MAO) as activator. From the powder X-ray diffraction (XRD) analysis it was observed that the basal spacing of the activated organoclay…
In this paper we present the microstructural study behind the growth of carbon nanotubes (CNTs) on the multimetal buffer layers due to its importance in microelectronics and microelectromechanical systems applications. Two different buffer layers, i.e., aluminum (Al) and titanium nitride (TiN), were deposited on the c…
This paper presents the analysis of leakage current characteristics of outdoor polymer insulator due to pollution under wet conditions. In this work, laboratory based pollution performance tests were carried out on 11kv silicon rubber polymer insulator under AC voltage at different pollution levels with sodium chlorid…
The structures adopted by a range of hydrotris(3,5-dimethylpyrazolyl)methane complexes [ML(2){HC(pz')(3)}](+) (M = Rh, Ir; L(2) = diene) have been investigated. There is low steric hindrance between ligands in [Rh(eta-nbd){HC(pz')(3)}](+) (nbd = norbornadiene) and [Rh(eta-dmbd){HC(pz')(3)}](+) (dmbd = 2,3-dimethylbuta…
We report first-principles electronic structure calculations of the nuclear magnetic resonance (NMR) spin-spin coupling tensors to the (19)F nucleus in peri-difluoronaphthalene. This system was recently subjected by Emsley and co-workers to an experimental liquid crystal NMR study, and the 4-bond (19)F(19)F coupling w…
The nickel selenide thin films were prepared onto microscope glass slides by chemical bath deposition technique. The X-ray diffraction and scanning electron microscopy have been used for their structural and morphological characterization. The X-ray diffraction result shows that thin films have a polycrystalline and r…
Compression tests were conducted at the temperature of 573 K with the true strain rates of 0.1 s−1 on Mg-9Al-1Zn-1Ca and Mg-9Al-1Zn (in mass%) alloys, and the dynamic recrystallization behaviors were examined. Superplastic deformation of the alloys at 573 K after the hot compression was also investigated. When the hom…
水生植物ウキクサ－根圏微生物共生系により河川水試料中の4－t－ブチルフェノール（4－t－BP）の分解を試みた。河川水のみでは有意な4－t－BP分解は生じなかったが、ウキクサ存在下では河川水中の4－t－BPが有意に分解された。分解試験後のウキクサ根圏より4－t－BPおよび4－n－BPの分解菌の集積を試みたところ、4－t－BP分解能は集積の過程で失われてしまったが、4－n－BP分解能は維持され、最終的に4－n－BPを唯一の炭素源として増殖できるPseudomonas veroniiに属する3菌株の分解菌が分離された。そこで、分離菌株のひとつP. veronii nBP5株を対象として、更なる特徴づけを行った。nBP5株は、4－n－BP…
