A theoretical study for temperature dependence of levitation force of high-T-c superconductors
(Elsevier, 2013)
The temperature effect on the levitation force of a cylindrical type-II superconductor was investigated theoretically by solving the critical state equation. Analytical expressions are obtained for the levitation force ...
Effects of initial cooling conditions and measurement heights on the levitation performance of bulk MgB superconductor at different measurement temperatures
(Springer/Plenum Publishers, 2014)
The levitation properties of MgB prepared by hot press at 200 C and then pellet/closed tube method has been investigated. the vertical and lateral levitation forces ( and on a cylindrical NdFeB permanent magnet (PM) below ...
Investigation of Cd1-xCoxS diluted magnetic semiconductor thin films fabricated by chemical bath deposition method
(Elsevier Science Sa, 2014)
Chemical bath deposition method was used for preparation of Cd1-xCoxS thin films. the effects of Co doping and thermal annealing on structural, optical, electrical and magnetic properties of CdS thin films were investigated. ...
Investigation on the levitation force behaviour of malic acid added bulk MgB2 superconductors
(Elsevier, 2014)
The effects of malic acid addition (from 0 to 15 wt% of the total MgB2) on the levitation force properties of bulk MgB2 have been investigated. All samples were prepared from magnesium powder, amorphous boron powder, malic ...
Comparison of levitation forces of bulk MgB2 superconductors produced by nano boron and carbon-doped nano boron
(Springer, 2014)
MgB2 bulk superconductors were prepared by hot press plus furnace heating method. Two types of boron powders were used, one is amorphous nano boron and the other is C-doped boron. Characteristics of superconductors were ...
Validation of classical quantitative fundamental parameters method using multivariate calibration procedures for trace element analysis in ED-XRF
(Royal Soc Chemistry, 2014)
In this study, the X-ray intensities obtained from 76 soil samples were converted to concentrations by means of the Epsilon software program applying the fundamental parameters method (FP). Various National Institute of ...
Precision and accuracy of ST-EDXRF performance for As determination comparing with ICP-MS and evaluation of As deviation in the soil media
(Pergamon-Elsevier Science Ltd, 2014)
The present study was conducted to (i) determine the precision and accuracy of arsenic measurement in soil samples using ST-EDXRF by comparison with the results of ICP-MS analyses and (ii) identify the relationship of As ...
