66 -- THEORETICAL STUDIES IN MODEL FLUIDS SOL NB838000006745JW DUE 020700 POC Jacqueline Wright (303) 497-5282, FAX (303) 497-3163 E-MAIL: NOAA; MASC Acquisitions Management, Brenda.S.Summers@noaa.gov. The National Institute of Standards and Technology (NIST), intends to negotiate with only one source, Dr. Leo Lue, to procure theoretical, simulational, and database research on model systems including square-well fluids, structured polymers, and fluids undergoing a gel transition. The project includes studies of linear and star polymers, phase behavior for model colloids, and model fluids in higher dimensions. The simulations will include both Monte Carlo and molecular dynamics approaches, and the theoretical studies are based on liquid state theory and mode coupling approaches. Explicit consideration of critical and crossover behavior is required as part of the study. Dr. Lue is the only PhD-level researcher with the combination of skills required to undertake this research in the requisite eight-month time frame. He has experience with simulations for both monomer systems interacting with discontinuous potentials and with simulations of structured molecules including such architectures as chains anddendrimers; he has worked with both Monte Carlo and thermostatted molecular dynamics simulations and has publications showing the connections between crossover theory and simulation data for such polymeric systems. Additionally, Dr. Lue is familiar with the database structures used at NIST for the archiving and manipulation of experimental and simulational data, and is familiar with the scattering experiments (optical, neutron, and x-ray) which parallel the theoretical and computer simulation studies of gelling systems. An alternative researcher would require significant training before progress on the specific research objectives could be achieved. Interested sources must submit a written qualification statement and must contain sufficient information to clearly establish the ability to provide the theoretical, simulational, and database research as stated above, by February 7, 2000. Responses must reference Synopsis No. NB838000006745JW. This announcement/solicitation is being issued under the Simplified Acquisition Procedures, FAR Part 13 (NTE $100,000.00) and is not a request for quotes. The award decision will be based upon the best value to the Government, with technical merit, past performance and availability being significantly more important than price. Terms and Conditions and agency level protest procedures are referenced at http://netsite.esa.doc.gov.oam. Technical questions can be directed to Daniel Friend at (303) 497-5424. In the absence of other qualified sources, it is the intent of the Government to negotiate on a sole source basis with Leo Lue, Boulder, CO.
