20090318285 | IRON OXIDE CONTAINING PRECIPITATED CRYSTALLINE TITANIUM DIOXIDE AND PROCESS FOR THE MANUFACTURE THEREOF - The present invention is directed to a process for the manufacture of iron oxide particles coated with crystalline titanium dioxide, wherein the process comprises the steps of adding an aqueous solution of at least one titanyl salt to an iron oxide dispersion to form a reaction mixture, precipitating titanium dioxide on said iron oxide particles by adding an alkali, wherein the titanium dioxide is at least partially in a crystalline form, and isolating the resulting titanium dioxide-containing iron oxide particles from the reaction mixture. The invention is further related to iron oxide particles comprising precipitated crystalline titanium dioxide and the use of the resulting photocatalitycally active material. | 12-24-2009 |
20110070138 | USE OF PHOTOCATALYTICALLY COATED PARTICLES FOR DECOMPOSITION OF AIR POLLUTANTS - The invention relates to the use of iron oxide particles coated with titanium dioxide, and in particular to their use for decomposing air pollutants photocatalytically. The invention is further directed to the use of iron oxide particles being at least partially coated with titanium dioxide, for photocatalytically decomposing air pollutants selected from nitrogen oxides (NO | 03-24-2011 |

20140105790 | Chemoresistor Type Gas Sensor having a Multi-Storey Architecture - A multi-storey gas sensor is constructed by stacking chemoresistor type gas sensing elements and providing holes through each sensing element so gas can pass from one sensing element to the next, through the sensing layers. A rich data set can be obtained by selecting appropriate combinations of materials for the different sensing layers and varying the operating conditions of the different gas-sensing elements by: taking measurements when different combinations of sensing layers are activated, when given sensing layers are heated to different temperatures or according to different heating profiles, and/or when selected sensing layers are exposed to UV light. Sensor sensitivity and selectivity can be increased by applying UV pulses of controlled duration, and target gas species can be detected based on the transient response of the sensing layer at onset of UV irradiation. Each sensing element may have a micro-hotplate architecture. | 04-17-2014 |
