Deep drawing of polymer coated metal sheets
(Korean Society of Mechanical Engineers, 2019)
In the present study, the deep drawing of polymer coated metallic sheets were experimentally investigated to reduce friction and increase manufacturing efficiency without using a lubricant. Coating of metal sheets with a ...
Production of Un-Doped and Er-Doped Y2O3 Thin Films by Electron Beam Evaporation Method
(Springer, 2019)
In this study, un-doped and doped yttrium oxide (Y2O3) powders with different erbium concentrations were synthesized using sol-gel method. The synthesized powders were investigated by Raman analysis and the evolution of ...
Effects of dopant rate and calcination parameters on photoluminescence emission of Y2O3:Eu3+ phosphors: A statistical approach
(Elsevier Sci Ltd, 2019)
In this study, Y2O3:Eu3+ phosphorescent powders with different dopant rates were synthesized by sol-gel method. Statistical experimental design methods were used to investigate the effects of calcination temperature (800, ...
Formation of alpha/beta-Si(3)N(4 )nanoparticles by carbothermal reduction and nitridation of geopolymers
(Wiley, 2019)
Silicon nitride (Si3N4) particles with various alpha/beta-Si(3)N(4 )ratios were fabricated from geopolymer (GP)-carbon compositions (M2O center dot Al2O3 center dot 4.5SiO(2)center dot 12H(2)O+18C), where M is an alkali ...
Determination of aflatoxins in walnut sujuk and Turkish delight by HPLC-FLD method
(Elsevier Ltd, 2016)
This study aims to assess the risk of aflatoxins (AFs) in traditional confectionery products (walnut sujuk and Turkish delight) of Turkey. A high performance liquid chromatography coupled with fluorescence detection ...
Exergy analysis of coil-spring turbulators inserted in the horizontal concentric tubes
(2010)
In this study, to obtain definitive information about the effects of spring-type turbulators located in the inner pipe of a concentric heat exchanger, the rates of exergy transfer Nusselt number (Nue) and exergy loss (E*) ...
