Effect of processing parameters on structural, morphological and optical Y2O3:Yb3+/Ho3+ powders characteristics
(Advanced Powder Technology, 2014)
Rod-like and flake-like up-converting Y2O3:Yb3+/Ho3+ particles which are composed of nanoparticles with size less than 100 nm, are prepared by a simple hydrothermal processing at 473 K (3 h) followed by additional thermal ...
Structure-activity relationship of nanosized porous PEG-modified TiO2 powders in degradation of organic pollutants
(Advanced Powder Technology, 2015)
This study aims to gain insights in structure-activity relationship of TiO2 photocatalysts. For this purpose photocatalysts were synthesized via classical sol-gel method using titanium isopropoxide as a precursor and ...
Optimization of the classification process in the zigzag air classifier for obtaining a high protein sunflower meal - Chemometric and CFD approach
(Advanced Powder Technology, 2017)
In this study, sunflower meal is ground by a hammer mill after which air zigzag gravitational air classifier is used for separating sunflower hulls from the kernels in order to obtain protein rich fractions. Three hammer ...
Modified screw conveyor-mixers - Discrete element modeling approach
(Advanced Powder Technology, 2015)
Screw conveyors are widely used in the food industry, building construction and mining companies, chemical, agricultural and processing industries, mostly for elevating and/or transporting bulk materials over short to ...
