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, ...
The Effect of Colemanite on Thermal Properties of Recycled Polyethylene
(Polish Acad Sciences Inst Physics, 2019)
Boron is known as a rare and one of the most important elements for future engineering. Boron is naturally present in nature in the form of minerals, such as tincal, ulexite, colemanite, boracite, datolite and so on. Besides ...
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 ...
