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 ...
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 ...
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 ...
Modelling of relation between synthesis parameters and average crystallitesize of Yb2O3 nanoparticles using Box-Behnken design
(Elsevier, 2020)
A straightforward wet chemical method has been applied for the fabrication of Yb2O3nanoparticles (NPs) fromytterbium nitrate solution by using ammonium carbonate as precipitation agent. Effects of precursor molarity(0.1, ...
Effects of the alumina reinforcement ratio on the corrosion properties of iron based composite materials
(Carl Hanser Verlag, 2020)
Iron based composite materials reinforced with various ceramic particles are used in operating conditions requiring features such as high hardness, strength and wear resistance. The composite materials may be subject to ...
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 ...
ZrO2 coating via e-beam evaporation on PE separators for lithium-ion batteries
(Springer Heidelberg, 2021)
In this paper, ZrO2 is deposited on a polyethylene-based separator via electron beam evaporation method. The analyses reveal that the application of the ceramic-based coating enhances the electrolyte uptake capability from ...
Synthesis, characterization and radioluminescence properties of erbium-doped yttria phosphors
(Springer, 2021)
Radioluminescence (RL) behaviour of erbium-doped yttria nanoparticles (Y2O3:Er3+ NPs) which were produced by sol-gel method was reported for future scintillator applications. NPs with dopant rates of 1at%, 5at%, 10at% and ...
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, ...
