Influence of calcination temperature on microstructure and surface charge of membrane top layers composed of zirconia nanoparticles
(Australian Ceramic Society, 2015)
The purpose of the research is to investigate the changes in microstructure and physicochemical characteristics, mainly surface charge (i.e. zeta potential) of zirconia membrane top layer during calcination. Zirconia is ...
Sol-gel derived mesoporous and microporous alumina membranes
Stable polymeric and colloidal boehmite sols were prepared by sol-gel process through controlled hydrolysis/condensation reactions. The particle sizes of the colloidal sols were in the 12-25 nm range depending on the process ...
Preparation of particulate/polymeric sol-gel derived microporous silica membranes and determination of their gas permeation properties
Monodisperse silica sols with well-defined spherical particles ranging in size from 5 to 310 nm were prepared through Stober process. Both particulate and polymeric sol-gel routes were employed for the preparation of stable ...
The effect of rare earth element doping on the microstructural evolution of sol-gel titania powders
The development of a better understanding of the low temperature nanophase evolution of high surface area titania (TiO2) based powders is essential for their use in photocatalytic applications. A series of rare earth (RE) ...
