4 Νοε 2021 · The results demonstrate the strong effect of particle size on membrane disruption and leakage behaviors, especially indicating the cytotoxicity of nano-sized TiO 2 particles improved with decrease of particle sizes. Therefore, the use of TiO 2 NPs as a food additive has potential health risks.
18 Ιαν 2012 · This study quantifies the amount of titanium in common food products, derives estimates of human exposure to dietary (nano-) TiO 2, and discusses the impact of the nanoscale fraction of TiO 2 entering the environment. The foods with the highest content of TiO 2 included candies, sweets, and chewing gums.
Nanosized materials were present in all of the food-grade TiO2 samples, and transmission electron microscopy showed that samples 1-5 contained 35, 23, 21, 17, and 19% of nanosized primary particles (<100 nm in diam.) by no., resp. (all primary P25 particles were <100 nm in diam.).
24 Αυγ 2018 · Nowadays, TiO 2 is being used frequently for photo degradation of organic molecules and water splitting for hydrogen generation. Most important applications include purification, disinfection of waste water, self-cleaning coatings for buildings in urban areas and the production of the green currency of energy (hydrogen) by splitting water.
Several nanostructures with unique properties have been fabricated by nanotechnology for biotechnological applications, 1,2,6,8,9,11-14 among which, nano-sized titanium dioxide (TiO 2) has been widely used. The element of titanium was first discovered in 1791 by William Gregor.
27 Απρ 2020 · Among transition metal oxide‐based nanoparticles, titanium dioxide (TiO2) nanoparticles have demonstrated significant potential owing to their fascinating properties and utilization in...
8 Οκτ 2014 · With as many as 21 critical summaries of the most recent experimental and theoretical findings by leading experts in the field, this issue provides an exhaustive picture of TiO 2 nanomaterials, ranging from their synthesis to properties, property modifications, and applications.
