EPR study of the structural phase transitions in chromium doped thallium indium disulphide
(Elsevier Science Bv, 2003)
The results of low-temperature electron paramagnetic resonance (EPR) investigations of Cr3+ doped TlInS2 single crystals in the temperature range 5-300K are presented. Remarkable temperature dependences of the linewidth ...

Frequency and voltage dependent surface states and series resistance of novel Si solar cells
(Elsevier Science Sa, 2006)
The forward and reverse bias capacitance-voltage (C-V) and conductance-voltage (G/omega-V) characteristics of novel Si solar cells are studied over a wide frequency and temperature range of 10-500 kHz and 79-400 K, ...
Removal of uranium from wastewater in Turkey
(Springer, 2007)
Adsorbents are thought to be the most effective method for recovering the low concentrations of uranium from the wastewater. Here we will synthesize the interpenetrating polymer networks (IPN) based on acrylonitrile (AN) ...
Determination of antimony by using tungsten trap atomic absorption spectrometry
(Pergamon-Elsevier Science Ltd, 2008)
An electrically heated tungsten coil was used as a trap in the determination of antimony. The technique consists of three steps. Initially, SbH(3) is formed by hydride generation procedure; then the analyte species in vapor ...
Coverage-oriented, prioritized testing - A fuzzy clustering approach and case study
(Springer-Verlag Berlin, 2007)
Existing test techniques focus on particular, relevant aspects of the requirements of the system under test (SUT). Real-life SUTs have, however, numerous features to simultaneously be considered, often leading to a large ...
Effects of illumination and Co-60 gamma-ray irradiation on the electrical characteristics of porous silicon solar cells
(Pergamon-Elsevier Science Ltd, 2008)
A new approach for hybrid metal-insulator-semiconductor (MIS) Si solar cells is adopted by Institute of Fundamental Problems for High Technology, Ukrainian Academy of Sciences. In order to interpret the effect of illumination ...
Low temperature catalytic CVOC oxidation over bimetalic (Zr-PILCs) nanocomposite clay catalyst
(2009)
Catalyst design focused on combining acidic properties of the pillared clay (Zr-PILC) and redox properties of appropriately chosen bimetallic dopants. Therefore, Zr-PILC was tailored with the Pd/Pt and Cu/Cr noble and ...
Evaluating the relations between brittleness and Cerchar abrasion index of rocks
(2010)
Physical and mechanical rock properties which can be directly determined or estimated empirically are always considered for rock excavability, rippability, boreability and cuttability. Brittleness (B) and Cerchar Abrasiveness ...
Peculiarities of light transmission at nematic-isotropic liquid and isotropic liquid-nematic phase transitions
(Natl Inst Optoelectronics, 2007)
The optical transmission in thermotropic nematogens for a large temperature interval and in regions of direct and reverse phase transitions between the nematic mesophase and isotropic liquid has been investigated. The ...
