Steam gasification of carbon: Catalyst properties
This research uses several techniques to measure the concentration of catalyst sites and determine their stoichiometry for the catalyzed gasification of carbon. Both alkali and alkaline earth oxides are effective catalysts for accelerating the gasification rate of coal chars, but only a fraction of the catalyst appears to be in a form that is effective for gasification, and the composition of that catalyst is not established. Transient techniques, with {sup 13}C labeling, are being used to study the surface processes, to measure the concentration of active sites, and to determine the specific reaction rates. We have used secondary ion mass spectrometry (SIMS) for both high surface area samples of carbon/alkali carbonate mixtures and for model carbon surfaces with deposited alkali atoms. SIMS provides a direct measure of surface composition. The combination of these results can provide knowledge of catalyst dispersion and composition, and thus indicate the way to optimally utilize carbon gasification catalysts.

Combating Terrorism: Observations on Biological Terrorism and Public Health Initiatives
Testimony issued by the General Accounting Office with an abstract that begins "Pursuant to a congressional request, GAO discussed its ongoing work and preliminary observations on the biological terrorist threat and some aspects of the Department of Health and Human Services' (HHS) bioterrorism initiative, focusing on: (1) intelligence agencies' judgments about the threat of terrorism; (2) the importance and benefits of threat and risk assessments to provide a sound basis for targeting the nation's investments in combating terrorism; (3) preliminary observations from GAO's ongoing work on the science behind the biological and chemical terrorist threat, with some focus on biological agents; and (4) overall observations on public health initiatives that deal with a new national pharmaceutical stockpile and the basis for selecting items to research, produce, procure, and stockpile for civilian defense against terrorism."
