Copper-deposited wire ion-selective electrode for the determination of copper(II)
(The Analyst, 1987)
A wire ion-selective electrode was made by sulphiding electrolytic copper previously deposited on commercial copper wire. Sulphidation was carried out by means of gaseous hydrogen sulphide at an increased temperature. The ...
Discrimination between some Chinese and Yugoslav winter wheat cultivars by capillary electrophoresis of gliadins
(Seed Science and Technology, 1998)
Gliadin proteins extracted from seventeen China and Yugoslav winter wheat cultivars were separated by capillary electrophoresis (CE). In order to optimise resolution and reproducibility of gliadin separations, different ...
Biodegradation of MTBE by Bacteria Isolated from oil Hydrocarbons-Contaminated Environments
(International Journal of Environmental Research, 2011)
Methyl tertiary butyl ether (MTBE) belongs to the group of gasoline oxygenates and persistent environment contaminants, and shows potential for biodegradation in aerobic and anaerobic conditions, through application of ...
Synthesis and characterization of novel Cd(II), Zn(II) and Ni(II) complexes with 2-quinolinecarboxaldehyde selenosemicarbazone. Crystal structure of bis(2-quinolinecarboxaldehyde selenosemicarbazonato)nickel(II)
(Pergamon-Elsevier Science Ltd, Oxford, 2007)
New complexes of Cd(II), Zn(II) and Ni(II) with 2-quinolinecarboxaldehyde selenosernicarbazone (Hqasesc) were synthesized and structurally characterized. The structure of the ligand, Cd(II) and Zn(II) complexes was determined ...
Dehydration investigations of a refractory concrete using DTA method
(Springer, Dordrecht, 2012)
The base mix refractory concrete is corundum-based, containing corundum as refractory aggregate and CAC as hydraulic binder, with a spinel as an additive. The authors investigated the dehydration reactions which occur from ...
The Effects of the pH Value of the Swelling Medium on the Kinetics of the Swelling of a Poly(acrylic acid) Hydrogel
(John Wiley & Sons Inc, Hoboken, 2010)
The isothermal kinetics curves of the swelling of a poly(acrylic acid) hydrogel in buffer solutions of different pH values (5, 7, and 9) at temperatures ranging from 30 to 40 degrees C were determined. The possibilities ...
Effect of dicamba on wheat haploid embryo development
(Akademiai Kiado Zrt, Budapest, 2008)
An interspecies zygote derives after wheat x maize crosses. This zygote aborts in absence of auxin stimulation. Treatment with dicamba is widely used to promote wheat haploid embryo development. We analyzed the effect of ...
Structure and thermal behavior of the layered zincophosphate [NH3-CH2-CH(NH3)-CH3](ZnPO4)(2)
(Elsevier Science Sa, Lausanne, 2009)
A zinc phosphate with the composition [NH3-CH2-CH(NH3)-CH3](ZnPO4)(2), containing the doubly protonated 1,2-diaminopropane (abbr. HDAP), was synthesized by hydrothermal crystallization of zinc nitrate, phosphoric acid, ...
Evaluation of different methods for determining growing degree-day thresholds in apricot cultivars
(Springer, New York, 2010)
The aim of this study was to examine different methods for determining growing degree-day (GDD) threshold temperatures for two phenological stages (full bloom and harvest) and select the optimal thresholds for a greater ...
Copper(II) complexes of N-heteroaromatic hydrazones: Synthesis, X-ray structure, magnetic behavior, and antibacterial activity
(Elsevier Science Sa, Lausanne, 2009)
Three novel copper(II) complexes as condensation derivatives of 2-pyridinecarboxaldehyde, 2-acetylpyridine or 2-quinolinecarboxaldehyde with ethyl hydrazinoacetate hydrochloride were synthesized. X-ray crystal structures ...
