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) ...
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
(2014)
This study deals with the maximization of composite yield subjected to multiple product constraints simultaneously based on float-sink data of a lignite coal from Yozgat-AyrIdam district of Turkey by using equal incremental ...
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 ...
