Radioactivity measurements in soil samples collected in the Republic of Srpska
(Radiation Measurements, 2008)
During 2005 and 2006, soil samples were collected from different regions in the Republic of Srpska, in order to evaluate their radioactivity. During the war that lasted from 1994 to 1995, it is known that some locations ...
A channel for modification of materials with post-accelerated or decelerated multiply charged ion beams
(Nuclear Instruments and Methods in Physics Research. Section A: Accelerators, Spectrometers, Detectors, and Associated Equipment, 2008)
t present, heavy ion beams from the electron cyclotron resonance (ECR) ion source in the Laboratory of Physics of the Vinca Institute of Nuclear Sciences, Belgrade, Serbia, are employed in a channel for surface modification ...
Influence of antiferromagnetic spin ordering on the far-infrared active optical phonon modes of alpha-MnSe
(Physical Review B: Condensed Matter and Materials Physics, 2008)
The effects of spin-phonon interaction and magnetic anisotropy on the temperature dependence of the infrared optical phonon modes in the antiferromagnetic alpha-MnSe are investigated by use of Greens function formalism ...
Electronic properties of bilayered manganite Ca(2.5)Sr(0.5)GaMn(2)O(8) from first-principles calculations
(Physical Review B: Condensed Matter and Materials Physics, 2008)
By means of first-principles calculations using spin-polarized generalized gradient approximation method and ultrasoft pseudopotentials, the electronic and magnetic structure of the recently synthesized orthorhombic phase ...
TiO2 doped with nitrogen: Synthesis and characterization
(Journal of Nanoscience and Nanotechnology, 2008)
In this study, nitrogen-doped titanium dioxide (TiO2) powders were synthesized in two ways: by heating of titanium hydroxide with urea and by direct hydrolysis of titanium tetraisopropoxicle (TTIP) with ammonium hydroxide. ...
