We have succeeded in tuning the electric conductivity of nanostructured films composed of a conducting polymer (PEDOT-PSS) and an n-type inorganic semiconductor (TiO2 nanoparticles) by light irradiation at different wavelengths.

Chemical warfare agents (CWA) pose inevitable threat, both to soldiers and civilians. Risk on contact with these deadly agents can be avoided by neutralisation of their toxic effects. A suitable media with essential physico-chemical properties is required for this purpose. Considerable efforts have been made to develop several decontamination media suitable for neutralisation of highly toxic CWAs. This paper reviews history and details of recent technological advancements in the development of versatile, broad spectrum decontamination formulations against CWAs, as also nanosized metal oxides as CWA decontaminants.

in Wiley InterScience (www.interscience.wiley.com).Decontamination reactions of sulfur mustard and sarin were studied on the surface of titania nanotubes and the data were compared with that of bulk titania. Before the reaction studies, titania nanotube samples were made by using hydrothermal method and were characterized by scanning electron microscopy, N 2 BET, X-ray diffractometry, and thermogravimetry. Soon after that, titania nanotube samples were exposed to sulfur mustard and sarin separately at room temperature (308C) and the reactions were monitored by gas chromatography, whereas the reaction products were characterized by GC-MS. The data explore the role of hydrolysis reactions and surface reactions for the decontamination of both sulfur mustard and sarin.
