Theoretical assessment of calcium arsenates stability:Application in the treatment of arsenic contaminated waste
(Materials Science Forum, 2007)
Several approaches for immobilization of arsenic (As) based on the transformation of its soluble forms (compounds) into highly insoluble arsenate apatite Ca-5(AsO4)(3)OH have been proposed. These immobilization techniques ...
Monte Carlo calculation of X-rays deposited energy in CdZnTe detector
(Materials Science Forum, 2007)
CdZnTe detectors have been employed in diagnostic X-ray spectroscopy. This paper presents the Monte Carlo calculation of X-ray deposited energy in a CdZnTe detector for different energies of photon beam. In incident photon ...
Electron attachment to metallic clusters
(Materials Science Forum, 2007)
The calculations of the low-energy attachment cross section to metallic clusters are investigated. Low energy electrons are taken as slow enough to excite a giant dipole collective resonance within the cluster. The ...
Structural and magnetic properties of the Zn-Mn-O system
(Materials Science Forum, 2007)
Zn-Mn-O semiconductor crystallites with nominal manganese concentration x = 0.01, 0.02, 0.04 and 0.10 were synthesized by a solid state reaction route using oxalate precursors. Thermal treatment procedure was carried out ...
Reduction of nanometric magnetite powder
(Materials Science Forum, 2007)
The investigated nanometric magnetite powders were synthesized electrochemically, and examined by XRD and SEM techniques. Their reduction was conducted through the isothermal heating in hydrogen in the temperature range ...
Reaction with hydrogen of micro and nano composites based on Mg
(Materials Science Forum, 2007)
Hydrogen, being a regenerative and environmentally harmless fuel, can play a crucial role in the energetic scenario of the near future. In recent years several systems for solid-state hydrogen storage have been investigated, ...
