Thermal stress analysis of functionally graded disc with variable thickness due to linearly increasing temperature load
(Springer Verlag, 2013)
In this study, the elastic stress analysis of a hollow disk made of functionally graded materials was subjected to a linearly increasing temperature distribution. These disks have many applications in the aerospace industry, ...
Impact response of sandwiches with open-cell casting metal foam and GFRP skins
(Taylor and Francis Ltd., 2016)
The main advantage of using sandwich structures is their high strength, high energy absorbing capacity and high bending stiffness to weight ratio. Therefore, they are unique for the applications where the light-weight ...
Evaluation by multi gravity separator (MGS) of a low grade chromite tailing from Yesilova-Burdur (Turkey)
(Polish Mineral Engineering Society, 2019)
In this study, concentrability by a Multi-Gravity-Separator (MGS) of the chromite tailings with content 23.84% Cr2O3 from Yeşilova-Burdur (Turkey) is investigated. Mineralogical analyses showed that the chromite tailings ...
Synthesis and characterization of silicon carbide powders converted from metakaolin-based geopolymer
(Blackwell Publishing Inc., 2016)
Silicon carbide (SiC) ceramic powders were synthesized by carbothermal reduction in specific geopolymers containing carbon nanopowders. Geopolymers containing carbon and having a composition M2O·Al2O3·4.5SiO2·12H2O+18C, ...
Structural, electronic, and electrochemical analyses of sputter-coated Pt and Pt–Co/GCE electrodes with ultra-low metal loadings for PEM fuel cell applications
(Springer Netherlands, 2017)
In this study, unsupported platinum and platinum–cobalt ultra-thin catalyst layers with varying metal loadings were prepared by a sequential magnetron sputtering technique. The deposited catalyst layers were characterized ...
Electrochemical copper (II) sensor based on chitosan covered gold nanoparticles
(Kluwer Academic Publishers, 2014)
This study outlines a new sensing platform based on glassy carbon electrodes modified by gold nanoparticles (AuNPs) for the determination of heavy metal. A glassy carbon electrode was modified by chitosan stabilized AuNPs. ...
Atom-economical synthesis of complex heterocycles with N-O moiety
(Wiley Blackwell, 2015)
A concise and facile method for the synthesis of heterocyclic compounds with N-O tether was introduced. The two important steps of the synthesis are a Mitsunobu reaction and C-H activation. The Mitsunobu protocol allows ...
Effect of electrolytic nickel coating on fatigue life of iron based powder metal parts
(2011)
Electrolytic coating is one of the methods mainly used to provide corrosion resistance for the powder metal parts. The coatings have strong effects on mechanical properties of coated parts as well as on surface properties. ...
A novel two-layered glass-ceramic sealant design for solid oxide fuel cells
(John Wiley and Sons Ltd, 2017)
A thermo-mechanical stress develops on the sealant of an solid oxide fuel cell (SOFC) stack because of thermal expansion coefficient (TEC) differences among ceramic electrolyte, metallic interconnector, and glass-ceramic ...
A novel two-part interconnector for solid oxide fuel cells
(John Wiley and Sons Ltd, 2014)
A two-part interconnector is developed for solid oxide fuel cell stacks to reduce cost and to improve sealing. The novel interconnector involves a metallic core for current collection and gas distribution and a ceramic ...
