Influence of viscoelastic characteristics of the colloidal suspensions on the formation of SnO2 supported membranes
(1997-12-01)
SnO2 supported membranes have been prepared by sol-casting on alumina tubular substrate, using aqueous colloidal suspensions prepared by sol-gel route. The viscoelastic behaviour during sol ageing was analyzed by dinamic ...

Effect of electrolyte on the gelation and aggregation of SnO2 colloidal suspensions
(1992-12-01)
Electrolytes may modify the physical-chemical characteristics of colloidal particle interfaces in suspension, which can favour gel or aggregate formation. The influence of NH4Cl loading on the aggregation and gelation of ...

Shear rheology of hard-sphere, dispersed, and aggregated suspensions, and filler-matrix composites
(Elsevier Science, 2012-03)
This paper reviews the shear rheology of suspensions of microscopic particles. The nature of interparticle forces determines the microstructure, and hence the deformation and flow behavior of suspensions. Consequently, ...
Nanoparticle characterization of Er-doped SnO2 pellets obtained with different pH of colloidal suspension
(2013-08-28)
SnO2:2 at. %Er xerogel samples were obtained by sol-gel technique from colloidal suspensions with distinct pHs. The evaluation of critical regions inside the nanocrystallite is fundamental for the interpretation of the ...
