Latest Cretaceous "A(2)-type" granites in the Sakarya Zone, NE Turkey: Partial melting of mafic lower crust in response to roll-back of Neo-Tethyan oceanic lithosphere
(Elsevier Science Bv, 2018)
An integrated study of comprehensive geochronological, geochemical, and Sr-Nd-Hf isotopic data was undertaken for the A-type Topcam pluton that intruded within the Sakarya Zone (NE Turkey) with the aims of elucidating its ...
Exergetic performance comparison of air and hydrogen gas flowing through the annular curved duct
(Pergamon-Elsevier Science Ltd, 2018)
The main objective of this study is to parametrically compare the exergetic performance of air and hydrogen gas flow through the curved annular duct. For this purpose, it is assumed that, i) air and hydrogen are considered ...

Magnetic features of boron doping on Hf2Co11 thin films
(Springer, 2018)
The effect of boron (B) doping on the structural and magnetic properties is studied systematically in the Hf2Co11 thin films. the modified crystal microstructure and annealing process enhanced the coercive field up to 1754 ...
Comparing the pozzolanic activity properties of obsidian to those of fly ash and blast furnace slag
(Elsevier Sci Ltd, 2018)
The use of pozzolan in cement provides economic advantages and improves the physico-mechanical properties of cement. Fly ash and blast furnace slag are widely used in cement as pozzolanic materials. in this study, obsidian ...

Thermoelectric transport behaviours of n-type Mg-2 (Si,Sn,Ge) quaternary solid solutions
(Keai Publishing Ltd, 2019)
Mg2X (X=Si, Sn, and Ge) based systems have attracted widespread attention owing to their various benefits in thermoelectric applications. in particular, to date, ternary Mg2X based solid solutions have become one of the ...
The effect of Total flowrate on the cooling performance of swirling coaxial impinging jets
(Springer, 2019)
Thermal management ability of swirling coaxial confined impinging air jets (SCCIAJ) are experimentally studied for different total flowrate. the coaxial structure of the jet is provided by a nozzle which is a cylindrical ...
Effect of strontium and magnesium additions on the microstructure and mechanical properties of Al-12Si alloys
(Korean Inst Metals Materials, 2019)
In this study, a binary Al-12Si, eight ternary Al-12Si-Sr, and six quaternary Al-12Si-0.1Sr-(0.2-1)Mg alloys were produced by permanent mold casting. It was observed that microstructure of the binary alloy consisted of the ...
Numerical analysis of the receding contact problem of two bonded layers resting on an elastic half plane
(Techno-Press, 2019)
