Comparison of photocatalytic activities of titanium dioxide.

Titanium dioxide photocatalytic inactivation of prions.

Prions are postulated to be the infectious agents of a family of transmissible, fatal, neurodegenerative disorders affecting both humans and animals. The possibility of prion transmission constitutes a public-health risk that confronts regulatory authorities everywhere. The main problem in handling prions is the fact that they are extremely resistant to standard decontamination methods. Thus, t...

Reusable photocatalytic titanium dioxide-cellulose nanofiber films.

Titanium dioxide (TiO2) is a well-studied photocatalyst that is known to break down organic molecules upon ultraviolet (UV) irradiation. Cellulose nanofibers (CNFs) act as an attractive matrix material for the suspension of photocatalytic particles due to their desirable mechanical and optical properties. In this work, TiO2-CNF composite films were fabricated and evaluated for photocatalytic ac...

Titanium dioxide mediated photocatalytic degradation of malathion in aqueous phase

The photocatalytic degradation of technical grade pesticide ‘malathion’ has been studied in aqueous suspensions of TiO2. The main aim of using this process is to degrade the toxic complex structure of the pesticide to harmless products by treating the sample in the UV-reactor. The COD measurements are carried out in order to study the percentage mineralization and degradation is studied under d...

Titanium Dioxide Mediated Photocatalytic Degradation of Chlorpyrifos in Aqueous Phase

Photocatalytic inactivation of Cryptosporidium parvum on nanostructured titanium dioxide films.

Control of waterborne gastrointestinal parasites represents a major concern to water industries worldwide. In developed countries, pathogens in drinking water supplies are normally removed by sand filtration followed by chemical disinfection. Cryptosporidium spp. are generally resistant to common disinfection techniques and alternative control strategies are being sought. In the current study, ...
