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
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, ...

Pheromone paths attached to the substrate in meliponine bees: helpful but not obligatory for recruitment success
In contrast to marking of the location of resources or sexual partners using single-spot pheromone sources, pheromone paths attached to the substrate and assisting orientation are rarely found among flying organisms. ...
