Method of improving catalytic activity and catalytics produced thereby

Description: A process for dissociating H{sub 2}S in a gaseous feed using an improved catalytic material is disclosed in which the feed is contacted at a temperature of at least about 275C with a catalyst of rutile nanocrystalline titania having grain sizes in the range of from about 1 to about 100 manometers. Other transition metal catalysts are disclosed, each of nanocrystalline material with grain sizes in the 1--100 nm range. This invention may have application to vehicle emissions control (three-way catalysts).

Device for calibrating a radiation detector system

Description: The present invention relates to a device for calibrating a radiation detector system that is used for measuring the radionuclide intake of those exposed to radioactive materials. In particular, the present invention relates to a device that simulates a human chest and lungs with a modicum of internal radiation for use in calibrating radiation detectors.
