veloped by and for federal agencies during 1982. Orders (accompanied by a check for $19.50) should be addressed to U.S. Department of Commerce, National Technical Information Service, 5285 Port Royal Rd., Springfield, Va. 22161. Specify NTIS Order No. PB83-121533/TAR "Federal Technology Catalog—1982." The Regional Laser and Biotechnology Laboratories is soliciting users for the facility, which is associated with the University of Pennsylvania. Laser experiments, including but not limited to, transient absorption spectroscopy, fluorescence and fluorescence excitation spectroscopy, and kinetics measurements over a wide range of time scales can be performed. All experiments are subject to a short review process to establish scientific interest and feasibility. For more information contact Gary Holtom, Regional Laser and Biotechnology Laboratories, University of Pennsylvania, Philadelphia, Pa. 19104; 215-898-5891. Chemical Abstracts Service's CAS ONLINE search service now includes abstracts of over 3.6 million scientific papers and patents and Chemical Abstracts index entries for more than 5.7 million documents. Abstracts available for display include essentially all those published in Chemical Abstracts since mid-1975 plus a limited number of those published between 1967 and mid-1975. All bibliographic citations, keyword index terms from the weekly Chemical Abstracts issue indexes, and subject and substance index entries from the semiannual volume indexes since 1967 are currently available for retrieval and display. Later this year CAS ONLINE will be expanded to make the bibliographic references and index entries searchable. The Department of Energy and eight industrial firms are sponsoring a project at the NBS laboratories in Boulder, Colo., to provide improved thermophysical property data for supercritical extraction processes. Objectives include development of a mathematical model for carbon dioxide mixtures in the near-critical and supercritical regions and development of an equation of state for carbon dioxide. The project will also include research on potential extracting fluids and development of phase equilibria measurements for solvent-hydrocarbon systems. For more information contact Neil A. Olien, Division 773, NBS, Boulder, Colo. 80303; 303-4973257.
