Influence of Ge content and annealing conditions on the PL properties of nc-Si1-xGex embedded in SiO2 matrix in weak quantum confined regime
(Elsevier Science Bv, 2014)
Fabrication of Si (nc-Si), Ge (nc-Ge), and Si1-xGex (nc-Si1-xGex) nanocrystals embedded in SiO2 matrix is achieved by thermal annealing of magnetron-sputtered thin films. Effects of annealing conditions, namely duration ...
Structural characterizations and optical properties of InSe and InSe: Ag semiconductors grown by Bridgman/Stockbarger technique
(Elsevier, 2014)
Undoped InSe and Ag doped InSe (InSe:Ag) single crystals have been grown by using the Bridgman/Stockbarger method. the freshly cleaved crystals have mirror-like surfaces even without using mechanical treatment. the structure ...
The magnetic and magnetocaloric properties of CoMnGe1-xGax alloys
(Elsevier Science Sa, 2014)
The magnetic and magnetocaloric properties of CoMnGe1 Ga-x(x) (0.02 <= x <= 0.063) alloys have been investigated by using calorimetric, X-ray diffraction and magnetic measurements. Our results show that the structural and ...
Sustainability assessment of PW6000 turbofan engine: an exergetic approach
(Inderscience Enterprises Ltd, 2014)
In this paper, theory, methodology and example application are developed and shown for a PW6000 high-bypass turbofan engine in terms of exergo-sustainable perspective. To obtain exergetic sustainability indicators, first, ...

The focus of this chapter is biomass conversion in the supercritical water. the two main processes of the supercritical conversion of biomass are the supercritical water gasification and the supercritical water oxidation. ...
Hydrothermal gasification of Rosa Damascena residues: Gaseous and aqueous yields
(Elsevier, 2014)
The gasification of Rosa Damascena residues - by-products of the rose-oil industry - was investigated under hydrothermal conditions at 500 degrees C and 600 degrees C, 35-45 MPa pressure with a reaction time of 1 h. the ...
Effects of ceramic based pastes on electrochemical performance of solid oxide fuel cells
(Elsevier Sci Ltd, 2014)
Various commercially available anode and cathode materials are investigated as the anode and cathode contact paste, respectively, for solid oxide fuel cells. in order to obtain a printable paste, chosen materials are mixed ...
Single and multiple doping effects of silicon-boron and fluorine on ZnO thin films deposited with sol-gel spin coating technique
(Springer, 2014)
Undoped, Si and B single doped, Si-B co-doped and Si-B-F triple doped ZnO thin films were grown by sol-gel spin coating method. Effects of these doping elements on microstructural, morphological and optical properties were ...
