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
Assessing the risks of manufactured nanomaterials.
TL;DR: Although progress has recently been made toward understanding the health and environmental consequences of these materials, challenges ramain for future research are still challenges.
Journal ArticleDOI
Size and Structure Matter: Enhanced CO2 Photoreduction Efficiency by Size-Resolved Ultrafine Pt Nanoparticles on TiO2 Single Crystals
Wei-Ning Wang,Woo-Jin An,Balavinayagam Ramalingam,Somik Mukherjee,Dariusz M. Niedzwiedzki,Shubhra Gangopadhyay,Pratim Biswas +6 more
TL;DR: A facile development of highly efficient Pt-TiO(2) nanostructured films via versatile gas-phase deposition methods is described, where the size of the Pt NPs and the unique 1D structure of TiO( 2) single crystals played an important role.
Journal ArticleDOI
Nanoparticles and the Environment
Pratim Biswas,Chang-Yu Wu +1 more
TL;DR: The “life history of nanoparticles” is presented, tracking it from its formation to its potential use and eventual fate in the environment, and the ability to characterize and capture these nanoparticles as well as their control is discussed.
Journal ArticleDOI
Role of Surface Area, Primary Particle Size, and Crystal Phase on Titanium Dioxide Nanoparticle Dispersion Properties
Komkrit Suttiponparnit,Komkrit Suttiponparnit,Jingkun Jiang,Manoranjan Sahu,Sirikalaya Suvachittanont,Tawatchai Charinpanitkul,Pratim Biswas +6 more
TL;DR: The role of particle surface area, primary particle size, and crystal phase on TiO2 nanoparticle dispersion properties is reported andTiO2 isoelectric point was found to be dependent on particle size and insensitive to particle crystal structure.
