Vacancy transfer probabilities from K to L shell for low atomic number elements at 5.96 keV
(Polish Academy of Sciences, 2010)
Vacancy transfer probabilities from K to L shell were measured using I K?/IK? intensity ratios for six elements in the atomic region 16 ? Z ? 22. The K X-rays from the targets excited by 5.96 keV (1.85 GBq 55Fe filtered ...
Levitation force at different temperatures and superconducting properties of nano-structured MgB2 superconductors
(Elsevier, 2010)
The levitation and pinning force properties of nanocrystalline MgB2 superconductors prepared by a mechanical alloying technique with varying milling duration have been investigated. Levitation force measurements under ...
The effect of partial Lu doping on magnetic behaviour of YBCO (123) superconductors
(Elsevier, 2010)
We have investigated the effect of Lutetium doping on YBCO prepared by conventional solid-state reaction method by means of XRD, AC susceptibility and DC magnetization measurements and theoretical analysis. AC susceptibility ...
Measurement of Lα, Lβ and Total L X-ray fluorescence cross-sections for some elements with 40≤Z≤53
(Elsevier, 2010)
Lα, Lβ and total L X-ray fluorescence (XRF) cross-sections have been measured for the nine elements (Zr, Nb, Mo, Ag, Cd, In, Sn, Sb and I) using photon energy 5.96 keV. In these the elements, Lα and Lβ spectra were derived ...
Effects of Meissner surface current on the microwave surface resistance of type-II superconductors
(Elsevier, 2010)
Influence of the Meissner current on the field-induced variations of the microwave (mw) surface resistance in type-II superconductors is demonstrated to be well reproduced by exploiting different critical state models. ...
CdTe thin film solar cells prepared by a low-temperature deposition method
(Wiley, 2010)
Low-temperature vacuum deposition instead of the commonly used vacuum deposition at high substrate temperatures has been applied to prepare high efficiency (CdS/CdTe) solar cells. CdS and CdTe thin films have been subsequently ...
Radiological and chemical assessment of phosphate rocks in some countries
(Elsevier, 2010)
In this study, the radiological, structural and chemical characterizations of Mardin-Mazi{dotless}da?i{dotless} phosphate rock, which is an important phosphate fertilizer source in Turkey were investigated and compared to ...
Irreversibility line and flux relaxation in Bi:2223/Ag tape prepared by CTFF technique: H//c axis
(Springer Link, 2010)
We have studied flux dynamics in Bi:2223/Ag tape prepared by the CTFF technique in the orientation of H//c axis. Irreversibility line (IL) of a Bi:2223/Ag tape has been determined from AC susceptibility and the DC magnetization ...
Hydrogen production system design with synchronous buck converter
(IEEE, 2010)
Nowadays, the growing energy needs and the decreasing fossil fuels have made inevitable the use of new and renewable energy. The high cost of the renewable energy sources led to the need to develop more efficient and cheaper ...
