A New Approach for Cu and Fe/FexB Production from Chalcopyrite by Molten Salt Electrolysis
(Springer, 2020)
In the present study, copper (Cu) and iron boride -( FexB) were produced for the first time through molten salt electrolysis using chalcopyrite -(CuFeS2) in an oxide- based borax electrolyte. Molten salt electrolysis was ...
A comparison on physical, structural, and photocatalytical properties of TiO2 nanopowders produced using sol-gel and flame spray pyrolysis
(2013)
In this study, nanoscale photocatalyst TiO2 powders were synthesized via sol-gel and flame spray pyrolysis (FSP). Phase structures and ratios were analyzed by X-ray diffractometer (XRD). Size, specific surface area, and ...
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 ...
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. ...
The thermodynamic stability of intermediate solid solutions in LiFePO4 nanoparticles
(Royal Society of Chemistry, 2016)
Theoretical predictions from first principles and recent advances in in situ electrochemical characterization techniques have confirmed the presence of solid-solution states during electrochemical (de)lithiation of LiFePO4 ...
Particle-size and morphology dependence of the preferred interface orientation in LiFePO4 nano-particles
(Royal Society of Chemistry, 2014)
We gain new insights into the equilibrium properties and potential two-phase lithiation mechanisms in LiFePO4 nano-particles by conducting a first-principles investigation of the anisotropic chemical interfacial energy ...
Fully reacted high strength geopolymer made with diatomite as a fumed silica alternative
(Elsevier Ltd, 2017)
Geopolymers are formed by mixing of aluminosilicate sources with alkaline meta-silicate solution at room temperature. In the current study, diatomite of Turkish origin was fully utilized as a fumed silica alternative for ...
The effect of anodization parameters on the formation of nanoporous TiO2 layers and their photocatalytic activities
(Elsevier B.V., 2014)
In this work, nanoporous titanium dioxide (TiO2) layers were successfully formed by electrochemical anodization method on titanium (Ti) surface in fluorine containing electrolytes with different processing parameters. The ...
Abrasive wear, structure, and mechanical aspects of Al–Al2O3 composites fabricated using various mixing media during P/M routes
(Springer New York LLC, 2016)
The effects of mixing method during powder metallurgy (PM) routes on the abrasive wear behavior of Al–Al2O3p composite materials is investigated. For this purpose, starting Al powders with a constant volume fraction of 10% ...
