The effect of aging on the dark conductivity and noise in hydrogenated microcrystalline silicon thin films
(Wiley-V C H Verlag Gmbh, 2010)Aging hydrogenated microcrystalline silicon in air is found to affect both the dark conductivity and the 1/f noise. For a sample with a crystalline volume fraction of 0.39, the conductivity decreased by three orders of ... -
Hg and Se Speciation in Liver Tissue of Marine Birds
(Iop Publishing Ltd, 2013)X-ray fluorescence microprobe maps of Hg and Se distribution were made on liver tissue slices from marine birds (Cormorants) from Florida's Everglades. The birds bio-concentrate these toxic pollutants that are ingested ... -
Instability effects in hydrogenated microcrystalline silicon thin films
(Wiley-V C H Verlag Gmbh, 2010)Instability effects on the dark conductivity (sigma(Dark)) and photoconductivity (sigma(photo)) of microcrystalline silicon films with different microstructures deposited on smooth and rough substrates, after exposure to ... -
Investigation of light induced degradation in hydrogenated amorphous silicon-germanium alloy thin films using temperature dependent photoconductivity
(Wiley-V C H Verlag Gmbh, 2010)Light induced degradation of undoped hydrogenated amorphous silicon-germanium (a-SiGe:H) alloys with different Ge contents has been investigated using intensity and temperature dependence of photoconductivity between 78K ... -
Investigation of Thermal Properties of PUF/colored Organoclay Nanocomposites
(Polish Acad Sciences Inst Physics, 2015)Recently PF resins can be also prepared by the addition of urea because urea accelerates cure process of PF resin, reduces the cost and improves its strength performance. Clays have long been used as inorganic fillers in ... -
Magnetic measurements on HgMnTe epitaxial layers
(Amer Inst Physics, 1997)Magnetization measurements have been performed on epitaxial layers of Hg1−xMnxTe (MMT) using an alternating gradient field magnetometer (AGFM). The layers, which have a Mn concentration in the range 0.05<x<0.20, and ... -
Multiple Energy Synchrotron Biomedical Imaging System- Preliminary Results
(Springer Int Publishing Ag, 2015)The drive to improve and expand the amount of information extracted from various imaging modalities has led to the use of multiple (usually two) x-ray photon energies in computed tomography clinical systems. With the use ... -
Preparation and Characterization of Urea/Formaldehyde/Rosa Canina sp. Seeds Composites
(Polish Acad Sciences Inst Physics, 2014)Urea-formaldehyde (UF) resin which is one of the most important wood adhesives is a polymeric condensation product of the chemical reaction of formaldehyde with urea, and considered as the most important type of adhesive ... -
Properties of ZnO layers deposited by ''photo-assisted'' spray pyrolysis
(Elsevier Science Bv, 1996)Layers of ZnO have been deposited onto glass substrates by ''photo-assisted'' spray pyrolysis using zinc chloride and zinc acetate as precursors in aqueous and non-aqueous solutions. The structure of these films has been ... -
PV outdoor tests and 12 years of Mugla experiences
(Wiley-V C H Verlag Gmbh, 2015)In this paper, the electricity yield of photovoltaic power plant applications in the main campus of Mugla Sitki Kocman University, Turkey is presented. There are four small scale grid connected photovoltaic power plants ... -
Raman scattering under pressure and the phase transition in epsilon-GaSe
(Wiley-V C H Verlag Gmbh, 2003)Raman scattering in epsilon-GaSe has been investigated at room temperature in a diamond anvil cell by using helium gas as a pressure transmitting medium. The first observation of the solid-solid phase transition under ... -
Synthesis and Characterization of Phenol/Urea/Formaldehyde and Clay Composites
(Polish Acad Sciences Inst Physics, 2014)Recently, so-called "phenol-formaldehyde-urea resins", which are generally made only by mechanical blending of UF resin and alkaline type PF resins, have been used as adhesives for the manufacturing of wood products. Faster ...
