Growth kinetics of vanadium pentoxide nanostructures under hydrothermal conditions
(ElsevierAmsterdam, 2010-11)
The work reported here involved a study of the growth kinetics of V2O5nH2O nanostructures under hydrothermal conditions. The coarsening process of V2O5nH2O nanoribbons was followed by subjecting the as-prepared suspensions ...
Tailoring of heterostructures in a SnO2/TiO2 system by the oriented attachment mechanism
(American Institute of Physics (AIP), 2007-09-03)
In order to verify the possibility of forming a heterostructure-i.e., a nanoparticle tailored by the junction of two or more different materials-through the oriented attachment (OA) mechanism, experiments with rutile TiO2 ...

STUDY GROWTH OF TiO2 NANOCRYSTALS
In the last three decades, the development of nanotechnology has become a reality in many areas of industry and science, already reaching applications in society in sectors such as: health, ...
Estudo computacional das interações entre nanopartículas de dióxido de titânio envolvidas no processo de coalescência orientada
(Universidade Federal de São CarlosUFSCarPrograma de Pós-Graduação em Química - PPGQCâmpus São Carlos, 2018-04-03)
Experimental and theoretical studies have shown that the aggregation of TiO2 anatase nanoparticles (NPs) occurs with preferential crystallographic orientation by the so-called oriented attachment mechanism (OA). The growth ...
Growth kinetics of tin oxide nanocrystals in colloidal suspensions under hydrothermal conditions
(Elsevier B.V., 2006-09-29)
Colloidal suspensions of tin oxide nanocrystals were synthesized at room temperature by the hydrolysis reaction of tin chloride (II), in an ethanolic solution. The coarsening kinetics of such nanocrystals was studied by ...

Unified ZnO Q-dot growth mechanism from simultaneous UV–Vis and EXAFS monitoring of sol-gel reactions induced by different alkali base
(2016-11-01)
This article aims to give experimental evidences of the universality of main steps involved in ZnO nanoparticles formation and growth from sol-gel process. In this way, we revisit the effect of the alkali base (LiOH, NaOH, ...
