4-Amino-3,5-diethyl-4H-1,2,4-triazole at 100 K: Chains of edge-fused R 44(10) and R44(20) rings
(Wiley, 2007)
The title compound, C6H12N4, has four crystallographically independent mol-ecules in the asymmetric unit. Inter-molecular N - H?N hydrogen bonds involving amino groups and triazole N atoms form a three-dimensional framework ...
Ag diffusion in ZnS thin films prepared by spray pyrolysis
(Elsevier, 2007)
ZnS thin films were deposited by spray pyrolysis method on glass substrates. Diffusion of Ag in ZnS thin films was performed in the temperature range 80-400 °C under a nitrogen atmosphere. The diffusion of Ag is determined ...
2'-[Eth-oxy(p-tol-yl)methyl-ene]acetohydrazide
(2007)
Mol-ecules of the title compound, C12H16N2O2, are linked by N - H?O hydrogen bonds [N?O = 2.971 (2) Å, H?O = 2.17 (2) Å and N - H?O = 162 (2)°] into cyclic centrosymmetric R 2 2(8) dimers. © International Union of ...
2'-[Eth-oxy(phen-yl)methyl-ene]acetohydrazide
(2007)
The title compound, C11H14N2O2, contains two independent mol-ecules in the asymmetric unit. Each independent mol-ecule exists as part of an N - H?O hydrogen-bonded centrosymmetric dimer. © International Union of Crystallography ...
Biotypes and antibiotic resistance patterns of Gardnerella vaginalis strains isolated from healthy women and women with bacterial vaginosis
(2007)
As Gardnerella vaginalis is accepted as a member of normal vaginal flora, it is one of the dominant species which has been related to bacterial vaginosis (BV). The aim of this study was to determine the isolation rate, ...
Assessment of mercuric chloride toxicity on rainbow trouts (Oncorhynchus mykiss) and chubs (Alburnoides bipunctatus)
(Asian Network for Scientific Information, 2007)
Acute toxicity of mercury-II chloride (HgCl2), one of most toxic pollutants for aquatic ecosystems, in chub (Alburnoides bipunctatus) and rainbow trout (Oncorhynchus mykiss) was investigated in the present study. Actual ...
Synthesis and antimicrobial evaluation of novel di-triazoles and 4-arylidene amino 4,5 dihydro-1H-[1,2,4] triazole-5-one derivatives
(TUBİTAK, 2008)
A series of novel di-[3(thiophen-2-yl-methyl)-4,5-dihydro-1H-[1,2,4] triazole-5-one-4yl]n-alkanes (2a-h) were obtained by the reaction of N'-1-ethoxy-2-thiophen-2-yl-ethylydene hydrazino carboxylic acid ethyl ester (1) and ...
Luciobarbus kottelati, a new species of barbel (Teleostei: Cyprinidae) from the Büyük Menderes River, Turkey, with rediagnose of L. lydianus
(Magnolia Press, 2008)
Luciobarbus kottelati, new species, is described from the River Büyük Menderes, Aegean Sea drainage, Turkey. It is distinguished from all other species of Luciobarbus in Europe and western Anatolia by the pelvic-fin origin ...
Gadolinium diffusion-doping for enhancing activation energy in superconducting YBa2Cu3O7-x
(Elsevier, 2008)
The resistance transitions of Gd-diffused polycrystalline Y123 samples have been measured as a function of temperature and magnetic field. It is deduced from experimental results that the activation energy increases when ...
Investigation of the dependency of the upper critical magnetic field on the content x in Y1-xYbx/2Gdx/2Ba2Cu3O7-y superconducting structures
(Elsevier, 2008)
The Y1-xYbx/2Gdx/2Ba2Cu3O7-y superconducting samples for x = 0.0, 0.2, 0.4, 0.6, 0.8 and 1.0 were prepared by using the solid-state reaction technique. Resistivity measurements of the samples were performed in QD-PPMS ...
