Copper(II) complexes of N-heteroaromatic hydrazones: Synthesis, X-ray structure, magnetic behavior, and antibacterial activity
(Inorganica Chimica Acta, 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 ...
Influence of potential pulse conditions on the formation of honeycomb-like copper electrodes
(Journal of Electroanalytical Chemistry, 2009)
Electrodeposition of copper by pulsating overpotential (PO) regime in the hydrogen co-deposition range was examined by the determination of the average current efficiency of hydrogen evolution and by microscopic analysis ...
Strangeness production at low Q(2) in deep-inelastic ep scattering at HERA
(European Physical Journal C. Particles and Fields, 2009)
The production of neutral strange hadrons is investigated using deep-inelastic scattering events measured with the H1 detector at HERA. The measurements are made in the phase space defined by the negative four-momentum ...
Reactively sputtered Ni, Ni(N) and Ni3N films: Structural, electrical and magnetic properties
(Applied Surface Science, 2009)
Nickel thin films were deposited on glass substrates at different N-2 gas contents using a dc triode sputtering deposition system. Triode configuration was used to deposit nanostructured thin films with preferred orientation ...
Study of charm fragmentation into D (* +/-) mesons in deep-inelastic scattering at HERA
(European Physical Journal C. Particles and Fields, 2009)
The process of charm quark fragmentation is studied using D (* +/-) meson production in deep-inelastic scattering as measured by the H1 detector at HERA. The parameters of fragmentation functions are extracted for QCD ...
Modification of multilayered TiAlN/TiN coating by nanosecond and picosecond laser pulses
(Journal of Optics. A: Pure and Applied Optics, 2009)
A multilayered TiAlN/TiN coating deposited on H11 work-steel was irradiated by a TEA CO(2) laser (ns pulses) and a Nd:YAG laser (ps pulses), and the effects compared. The coating was 2.17 mu m thick and consisted of 45 ...
Preparation of Nanosized Non-Oxide Powders Using Diatomaceous Earth
(Science of Sintering, 2009)
In this paper the nanosized non-oxide powders were prepared by carbothermal reduction and subsequent nitridation of diatomaceous earth which is a waste product from coal exploitation. Our scope was to investigate the ...
Direct detection of unamplified DNA from pathogenic mycobacteria using DNA-derivatized gold nanoparticles
(Journal of Microbiological Methods, 2009)
Mycobacterial infections have a high economic, human and animal health impact. Herein, we present the development of a colorimetric method that relies on the use of gold nanoparticles for fast and specific detection of ...
Values of the derivatives of the cotangent at rational multiples of pi
(Applied Mathematics Letters, 2009)
By elementary arguments, we deduce closed-form expressions for the values of all derivatives of the cotangent function at rational multiples of pi. These formulae are considerably simpler than Similar ones which were found ...
Determination of Surface Properties of Various Oxides and Sulfides by Inverse Gas Chromatography
(Materials and Manufacturing Processes, 2009)
The surface properties of various oxides (ZrO(2) and Fe(3)O(4)) and sulfides (HgS and FeS) were investigated by the inverse gas chromatography method (IGC). The retentions of several organics were measured in the temperature ...
