Structural and low-field magnetic characterization of superconducting MgB2 wires
(Elsevier, 2004-10)
Superconducting MgB2 composite wires were prepared by packing blend of MgB2 inside of Cu tubes using powder in tube (PIT) method. The produced samples of the wires were then characterised by using SEM, XRD and AC susceptibility ...
Modification of Al-oxide tunnel barriers with organic self-assembled monolayers
(American Institute of Physics Publising, 1999-05)
Al-oxide tunneling barriers were modified by exposure to a vapor of n-octadecyltrimethoxysilane which forms self-assembled monolayers. The dynamic conductance dI/dV of the modified Al-oxide barrier between Al and Pb ...
Humidity sensing properties of ZnO-based fibers by electrospinning
(Elsevier, 2011-08)
Zinc oxide (ZnO) based fibers with a diameter of 80-100 nm were prepared by electrospinning. Polyvinyl alcohol (PVA) and zinc acetate dihydrate were dissolved in water and the polymer/salt solution was electrospun at 2.5 ...
Electrical and microstructural properties of superconducting MgB 2/Mg composites
(Trans Tech Publications, 2004)
MgB2/Mg composites were prepared to improve mechanical properties of brittle superconducting MgB2. MgB2 and Mg powders were mixed at different weight ratios and uniaxially pressed in a cylindrical dye at 0.5 GPa and at ...
Layered clay/epoxy nanocomposites: Thermomechanical, flame retardancy, and optical properties
(Wiley, 2008-07)
In this study, layered clay/polymer nano-composites were developed based on epoxy resins and montmorillonite as the nanoplatelet reinforcement. Clay particles were treated with hexadecyltrimethylammonium chloride (HTCA) ...
Electronic transport properties of microcrystalline silicon thin films prepared by VHF-PECVD
(Kluwer Academic Publishers, 2004-03)
Steady-state photocarrier grating (SSPG) and steady-state photoconductivity, σph, experiments have been carried out to investigate the electronic transport properties of undoped hydrogenated microcrystalline silicon (μc-Si: ...
Effect of humidity on electrical conductivity of zinc stearate nanofilms
(Elsevier, 2007-07)
In this work, stearic acid (StAc) and zinc stearate (ZnSt2) nanofilms were deposited on glass and silver substrates using Langmuir-Blodgett (LB) film technique and their structural and electrical properties were investigated. ...
Sub-bandgap absorption spectroscopy and minority carrier transport properties of hydrogenated microcrystalline silicon thin films
(National Institute of Optoelectronics, 2005-02)
Hydrogenated microcrystalline silicon thin films have been prepared using HW-CVD and VHF-PECVD techniques with different silane concentrations. The steady-state photoconductivity, dual beam photoconductivity, photothermal ...
MgB2 superconducting thin films sequentially fabricated using DC magnetron sputtering and thermionic vacuum arc method
(Elsevier, 2007-11)
In this work, we discuss fabrication and characterization of MgB2 thin films obtained by sequential deposition and annealing of sandwich like Mg/B/Mg thin films on glass substrates. Mg and B films were prepared using DC ...
Electrical characterization of interdigitated humidity sensors based on CNT modified calixarene molecules
(Polish Academy of Sciences Publishing, 2013-02)
In this study, we report on the optimization and characterization of chloroform soluble calix[4]arene derivative as a humidity sensor based on electrical properties. Due to the fact that calix[4]arene molecules are ...
