Decontamination and disinfection of water by solar photocatalysis: Recent overview and trends
TL;DR: In this article, the authors reviewed the use of sunlight to produce the OH radicals by TiO2 photocatalysis and photo-Fenton process and summarized most of the research carried out related to solar photocatalytic degradation of water contaminants and how it could significantly contribute to the treatment of persistent toxic compounds.
Journal ArticleDOI
High-performance lithium-ion anodes using a hierarchical bottom-up approach
TL;DR: A large-scale hierarchical bottom-up assembly route for the formation of Si on the nanoscale--containing rigid and robust spheres with irregular channels for rapid access of Li ions into the particle bulk.
Journal ArticleDOI
Characterization of size, surface charge, and agglomeration state of nanoparticle dispersions for toxicological studies
TL;DR: The role of important factors such as solution ionic strength, pH, and particle surface chemistry that control nanoparticle dispersion was examined in this article, where the size and zeta potential of four TiO2 and three quantum dot samples dispersed in different solutions (including one physiological medium) were characterized.
Journal ArticleDOI
Bio-nanocomposites for food packaging applications
TL;DR: The most promising nanoscale fillers are layered silicate nanoclays such as montmorillonite and kaolinite as mentioned in this paper, which can provide active and/or smart properties to food packaging systems.
