Space charge effect in the spiral inflector
(Nuclear Instruments and Methods in Physics Research. Section A: Accelerators, Spectrometers, Detectors, and Associated Equipment, 2000)
This paper presents the analytical and numerical theory of the space charge effects in the beam in the spiral inflector. It considers a simplified model of a straight cylindrical beam by using a uniform particle distribution. ...
Theory of the paraxial ion trajectory in the spiral inflector
(Nuclear Instruments and Methods in Physics Research. Section A: Accelerators, Spectrometers, Detectors, and Associated Equipment, 2000)
This paper presents the analytical and numerical theory of the paraxial ion trajectory through the spiral inflector. Analytical expressions for the equations which describe the paraxial ion trajectory are derived. The ...
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 ...
Evaluations of some classes of the trigonometric moment integrals
(Journal of Mathematical Analysis and Applications, 2009)
Four classes of the trigonometric moment integrals are evaluated in closed form in a simple and unified manner by making use of the contour integration in conjunction with the Cauchy integral theorem. In all cases, the ...
Cation distribution and size-strain microstructure analysis in ultrarine Zn-Mn ferrites obtained from acetylacetonato complexes
(Journal of Physical Chemistry. Part B: Condensed Matter, Materials, Surfaces, Interfaces and Biophysical, 2004)
The ultrafine ZnFe2O4, MnFe2O4, and cation deficit Zn-Mn ferrites were obtained by thermal decomposition of appropriate mixed complex compounds with acetylacetone (2,4-pentadione) ligands ([M(AA),]) at 500 degreesC. In ...
Optical and electron paramagnetic resonance spectroscopy of Cd1-xMnxS quantum dots
(Journal of Physics: Condensed Matter, 2004)
Cd1-xMnxS quantum dots (QDs) with diameter d less than or equal to 4.5 nm and with manganese concentrations from x = 0.001 to 0.15 have been prepared using aqueous solution precipitation. Absorption and fluorescence spectra ...
Intermolecular interactions between chelate rings and phenyl rings in square-planar copper(II) complexes
(European Journal of Inorganic Chemistry, 2004)
Analysis of the geometrical parameters in crystal structures of square-planar copper(II) complexes from the CSD shows that the short noncovalent copper (II)-phenyl carbon distances are a consequence of the interaction ...
A study of misleading effects of HCl treatment in the characterization of sulfur in coal
(Energy and Fuels, 2004)
The purpose of this study was to determine the cause of the experimentally noticed decrease of sulfate sulfur during a thermal treatment of coal. In the case of the pyrolysis of the investigated six coals of different rank ...
Surface Modification of Colloidal TiO2 Nanoparticles with Bidentate Benzene Derivatives
(Journal of Physical Chemistry. C, 2009)
Surface modification of nanocrystalline TiO2 particles (45 and ) with bidentate benzene derivatives, that is, 2-hydroxybenzoic acid, 2,5-dihydroxybenzoic acid, 2,3-dihydroxybenzoic acid, 3,4-dihydroxybenzoic acid, and ...
Electrical properties of a composite comprising epoxy resin and alpha-hematite nanorods
(Polymer, 2008)
Electrical properties of pure epoxy and epoxy-hematite nanorod composites have been investigated. The nanorods were synthesized by the forced hydrolysis method and further mixed with epoxy to obtain the nanocomposite. TEM ...
