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% ...
Effects of nitridation time and precursor particle size on yield of β-SiAlON synthesized from calcined kaolinite
(Springer New York LLC, 2019)
Carbothermal reduction and simultaneous nitriding (CTRN) of natural aluminosilicates is a method used to obtain phases of Si–Al–O–N system. SiAlON phases have important applications, such as high technology ceramics, for ...

Degradation of contaminated industrial waste water using sol-gel derived Ru-doped TiO2 photocatalytic films
(Foundation for Environmental Protection and Research (FEPR), 2013)
In this study, Ru-TiO2 films were deposited on glass substrates with a sol-gel route for degradation of contaminated industrial water. A solution with the Ru/Ti molar ratio of 0.05 was prepared using ruthenium and titanium ...
Optimization of coal flocculation with an anionic flocculant using a Box-Wilson statistical design method
(Oficyna Wydawnicza Politechniki Wroclawskiej, 2014)
In this study, the Box-Wilson statistical experimental design method was employed to evaluate suspension pH, salt (CaCl2·2H2O) concentration and anionic flocculant (A-150) amount in flocculation of coal. Response function ...
Size controllable synthesis and characterization of cuO nanostructure
(Trans Tech Publications Ltd, 2018)
In this study, copper oxide (CuO) nanostructures were successfully prepared by adding EG (ethylene glycol) and PEG (4000, 8000) (polyethylene glycol) via an in-situ chemical precipitation method. EG and PEG (4000, 8000) ...
In situ carbothermal reduction/nitridation carbon-nano powder added geopolymer composites
(American Ceramic Society, 2014)
Geopolymer was prepared by mixing metakaolin (Al2O3 center dot SiO2) with sodium water glass solution and then the activated carbon nano powder was added the geopolymer. To determine the best composition for carbothermal ...
Characterization and photocatalytic properties of nanoporous titanium dioxide layer fabricated on pure titanium substrates by the anodic oxidation process
(Elsevier Ltd, 2014)
Nanoporous titanium oxide (TiO2) layers were fabricated on commercially pure titanium (Cp-Ti) substrates by the anodic oxidation method under a potentiostatic regime. Anodic oxidation was performed in an aqueous solution ...
Determination of optimum washing conditions for a lignite coal based on ash and sulfur content
