Development of Titanium Dioxide (TiO2)-immobilized Buoyant Photocatalyst Balls Using Expanded Polystyrene (EPS)

Expanded polystyrene (EPS) floats for surveillance of Ochlerotatus japonicus.

Blocks of expanded polystyrene (EPS) were placed in a variety of habitats to investigate their potential as an egg-collection device for container-dwelling Aedes and Ochlerotatus species. Eggs from Ochlerotatus japonicus, Oc. triseriatus, Oc. hendersoni, and Aedes albopictus were collected with EPS floats. The float provides an inexpensive, low-maintenance alternative to the Centers for Disease...

Hydrogen Reduced Rutile Titanium Dioxide Photocatalyst

For TiO2 photocatalysts, recombination of photoexcited electrons and holes would occur in crystalline defects such as oxygen vacancies, Ti ions, and surface states. Therefore, it is believed that the density of crystalline defects should be decreased to improve the photocatalytic activity of TiO2 particles. Contrary to this common knowledge, the introduction of crystalline defects by hydrogen r...

Visible-light Photocatalyst - Nitrogen-doped Titanium Dioxide -

A new photocatalyst, known as nitrogen-doped TiO2 (TiO2-xNx), yielding high reactivity under visible light irradiation, together with high potential for mass-productivity, has been developed by using a highly time-efficient development technique that combines computational materials design with experimental syntheses. Under visible light irradiation, TiO2-xNx films and powders exhibit significa...

Use of Expanded Polystyrene (EPS) and Shredded Waste Polystyrene (SWAP) Beads for Control of Mosquitoes

Background: Mosquitoes transmit several diseases to human. There are several measures for control of larvae. As part of Integrated Vector Management (IVM) program, the utility of floating layers of polystyrene beads (EPS) is a potential alternative in habitats of mosquito larva. EPS beads prevent oviposition of mosquito as well as killing the immature stages by forming a tick layer on the water...
