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, ...
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 ...
A new approach to determine the outdoor temperature distributions for building energy calculations
(Pergamon-Elsevier Science Ltd, 2014)
This study formulated annual, monthly and hourly ambient temperature distributions for simplifying the calculation of cooling and heating degree-hours. in this regard, Turkey was selected as an application country, of which ...
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 ...
Comparing advanced exergetic assessments of two geothermal district heating systems for residential buildings
(Elsevier Science Sa, 2014)
Advanced exergy analysis method has been increasingly utilized in analyzing and assessing the performance of energy-related systems in recent years due to more deeply investigating the exergy destructions. in this study, ...
Fabrication and characterization of Al/Cu2ZnSnS4/n-Si/Al heterojunction photodiodes
(Wiley-V C H Verlag Gmbh, 2014)
Cu2ZnSnS4 (CZTS) thin film has been synthesized by a sol-gel spin-coating technique on the n-Si substrate to fabricate heterojunction photodiodes. An X-ray diffraction study has shown that the film is polycrystalline with ...
Geochemical fingerprints of Late Triassic calc-alkaline lamprophyres from the Eastern Pontides, NE Turkey: A key to understanding lamprophyre formation in a subduction-related environment
(Elsevier Science Bv, 2014)
The Eastern Pontides in NE Turkey is one of the major orogenic belts in Anatolia. in this paper, we report our new Ar-40/Ar-39 dating, mineral chemistry, major and trace elements and Sr-Nd-Pb isotopic analyses of the ...
Upper Campanian calciclastic turbidite sequences from the Hacimehmet area (eastern Pontides, NE Turkey): integrated biostratigraphy and microfacies analysis
(Polska Akad Nauk, Polish Acad Sciences, Univ Warsaw, Geology Dept, 2014)
The upper Campanian (Cretaceous) of the Hacimehmet area (south of the city of Trabzon; Eastern Pontides) is mainly composed of calciclastic turbidites. the basinal unit of the 119 m thick succession includes thin red pelagic ...
