Separation of whey components by using ceramic composite membranes
Ceramic supports were prepared from alumina powder and dip-coated with zirconia sol. The ceramic composite membranes prepared were characterized with respect to their microstructure/pore structures. The supports were 40% ...
Morphology of sodium salt of calf thymus DNA on mica, alumina, and silica surfaces: Effect of solvent and drying method
(Taylor & Francis, 2017-06)
Investigation of morphology of deoxyribonucleotide triphosphate (DNA) dried on different surfaces by atomic force microscopy (AFM) is important in DNA research that is focused on subjects of condensation for gene therapy, ...
Effect of pH and hydration on the normal and lateral interaction forces between alumina surfaces
Interaction forces between alumina surfaces were measured using an AFM-colloid probe method at different pHs. For an α-alumina-sapphire system at acidic pH, the force curve exhibited a well-defined repulsive barrier and ...
Influence of microstructure on the rheological behavior of dense particle gels
(American Institute of Chemical Engineers, 2005-01)
Rheological measurements are performed on highly concentrated alumina gels. By using an in situ mechanism based on enzyme-catalyzed internal reactions, we are able to form gels of highly concentrated particles without ...
Alumina/water suspensions in the presence of PEO-PPO-PEO triblock copolymers
The aim of this study was to investigate the stability and dispersion behaviour of aqueous alumina suspensions in the presence of polyethylene oxide-polypropylene oxide-polyethylene oxide (PEO-PPO-PEO) type triblock ...
Transesterification of sunflower oil on single step sol-gel made Al2O3 supported CaO catalysts: Effect of basic strength and basicity on turnover frequency
The activities of single step sol-gel made calcium oxide on alumina catalysts were studied as a function of CaO loading, methanol/oil molar ratio and the amount of the catalyst in the transesterification of sunflower oil ...
