The cytotoxic targets of anatase or rutile + anatase nanoparticles depend on the plant species
Biologia plantarum, 2017 The potential toxicity of nanoparticles (NPs) is under debate. Information about TiO2 NPs phytotoxicity is still limited partly due to the different TiO2 NP forms that may be found in the environment. The present work investigated the impact of different TiO2 NPs forms (rutile and anatase) on germination, growth, cell cycle profile, ploidy level, and ...

Formation and Stability of μ2-Peroxo on Titanosilicates, Anatase and Rutile: Implications for Zeotype Catalysts [PDF]
, 2023 Extra-framework TiO2 in titanosilicate oxidation catalysts has generally been linked with low selectivity and great emphasis has been put on developing synthetic protocols that yield anatase-free materials.

Sulphuric Acid Digestion of Anatase Concentrate
Mining, 2023 The processing of anatase ores by sulphuric acid digestion is well known for its low titanium dissolution yields, which makes the process economically and technically unfeasible. Anatase is considered much less reactive than other forms of titanium such as ilmenite and rutile. Generally, to enhance its dissolution, thermal processes along with acid and/

Water diffusion on TiO2 anatase surface [PDF]
AIP Conference Proceedings, 2015 Compatibility between biological molecules and inorganic materials, such as crystalline metal oxides, is strongly dependent on the selectivity properties and the adhesion processes at the interface between the two systems. Among the many different aspects that affect the adsorption processes of peptides or proteins onto inorganic surfaces, such as the ...

Bio‐Inspired Synthesis of Macroporous Single Crystal Particles as Scattering Agents
Advanced Functional Materials, EarlyView.A general strategy is presented that delivers unique, single‐crystal microparticles that combine submicron macroporosity and uniform particle shapes. A bioinspired approach is used to occlude three distinct types of additives – polystyrene microspheres, polymer vesicles and amino acids – within calcite single crystals, and subsequent thermal annealing ...
