Integral representations of the Legendre chi function
(Journal of Mathematical Analysis and Applications, 2007)
We, by making use of elementary arguments, deduce integral representations of the Legendre chi function chi(S)(z) valid for vertical bar z vertical bar LT 1 and Res GT 1. Our earlier established results on the integral ...
New integral representations of the polylogarithm function
(Proceedings of the Royal Society. A: Mathematical, Physical and Engineering Sciences, 2007)
Maximon has recently given an excellent summary of the properties of the Euler dilogarithm function and the frequently used generalizations of the dilogarithm, the most important among them being the polylogarithm function ...
Synthesis under self-controlled reaction conditions: Reaction of tetraamminezinc(II) chloride with 3,5-dimethyl-1-thiocarboxamide pyrazole
(Journal of Organometallic Chemistry, 2007)
The trinuclear [Zn-3(Hdmpz)(2)(dmpz)(4)(NCS)(2)] complex (Hdmpz: 3,5-dimethylpyrazole) has been synthesized by the reaction of tetraamminezinc(II) chloride with 3,5-dimethyl-1-thiocarboxamidepyrazole. The ammonia evolving ...
Thermodynamic description of the Ti-O system using the associate model for the liquid phase
(CALPHAD / Computer Coupling of Phase Diagrams and Thermochemistry, 2007)
The thermodynamic assessment of the Ti-O system was carried out by the CALPHAD method using the associate model for the liquid phase and the compound energy formalism for the solid phases. The derived set of parameters ...
First principle calculations of alkali hydride electronic structures
(Journal of Physics: Condensed Matter, 2007)
Electronic structure, volume optimization, bulk moduli, elastic constants, and frequencies of the transversal optical vibrations in LiH, NaH, KH, RbH, and CsH are calculated using the full potential augmented plane wave ...
Morphology and growth of electrodeposited silver powder particles
(Hydrometallurgy, 2007)
The effect of overpotential pulsing and periodic current reversal on the morphology of silver powders was investigated using a scanning electron microscope (SEM). It is shown that the profile of pulses or current reversal ...
Adsorption of Pb2+, Cd2+ and Sr2+ ions onto natural and acid-activated sepiolites
(Applied Clay Science, 2007)
The adsorption mechanisms of Ph2+, Cd2+ and Sr2+ ions on natural sepiolite and the influence of acid treatment on the adsorption capacity of sepiolite were investigated. The point of zero charge pH(pzc), is 7.4 +/- 0.1 for ...
Preparation and properties of nano-sized Ag and Ag2S particles in biopolymer matrix
(European Physical Journal E. Soft Matter, 2007)
Silver (Ag) and silver sulfide (Ag2S) nanoparticles were synthesized in a sago starch matrix. The resulting nanocomposites were investigated using structural, optical and thermal methods. XRD spectra of the nanocomposites ...
Study of sago starch-CdS nanocomposite films: Fabrication, structure, optical and thermal properties
(Journal of Nanoscience and Nanotechnology, 2007)
A synthetic procedure for the preparation of nanocomposite films of sago starch and CdS nanoparticles was introduced. The films were characterized using optical, structural, and thermal techniques. The formation of ...
Multivariate analyses of microelement contents in wheat cultivated in Serbia (2002)
(Food Control, 2007)
Microelements in soft winter wheat grain samples collected from all over Serbian wheat growing regions were analyzed quantitatively by atomic absorption spectrophotometry. Microelement contents differed markedly among wheat ...
