| Molecular simulation of sodium and chloride ions (red and yellow spheres) dissolved in supercritical water (green spheres), a high-temperature, high-pressure, fluid state of water that makes a salt (such as sodium chloride) much less soluble than it is in normal liquid water. Understanding this phenomenon may aid the design of processes for destroying organic wastes using supercritical water as the solvent. |
o get more bang for the buck, we are integrating our internal research activities and setting up partnerships with external research organizations. In these
ways, we can leverage and broaden our science and technology programs.
Research and development (R&D) integration is achieved through coordinated program planning, co-location of basic and applied programs within research divisions, and interdisciplinary teaming in mission areas. Each ORNL core competency represents an integration of as many as a dozen major R&D programs ranging from basic research through applications and technology transfer.
R&D partnerships with universities, industry, and other government laboratories strengthen and extend Laboratory programs while making more efficient use of technical resources and facilities. These partnerships include research collaborations, guest scientists and personnel exchanges, shared access to unique facilities, cooperative agreements with industry, and special relationships with other DOE facilities (including the Oak Ridge Y-12 Plant and K-25 Site), the University of Tennessee at Knoxville (UTK), the Tennessee Valley Authority (TVA), and other institutions.
In recent years, R&D partnerships at ORNL have significantly increased. Approximately 35% of ORNL research publications now include authors from other institutions, up from 20% five years ago. The number of guest scientists who perform research at the Laboratory has nearly doubled in 5 years. We host more than 2000 university and 1500 industry researchers per year. We maintain particularly close ties with UTK; through cooperative arrangements such as the ORNL/UT Science Alliance, more than 100 UTK faculty and graduate students perform research annually at ORNL. More than 160 CRADAs have been executed since 1990, representing $170 million in cooperative research with our industrial partners.
ORNL has two world-class capabilities that could make a world
of difference to industry. We can now model molecules, using powerful parallel computers. We have long
been able to scatter neutrons from a target in our HFIR to probe a
material's structure. Combining these capabilities, we can get for the
first time a coherent picture of molecules or molecular-level processes
responsible for properties such as unusual
strength or the ability to fight disease.
What's in it for industry? We can help design a synthetic motor oil
that will still work when lubricating superhot surfaces in highly
efficient engines. We can develop improved computer codes to model
enzymes produced by defective genes and design drugs to block these
enzymes' harmful effects. Other benefits of molecular simulations may be
designs for agents to cleanse polluted water and for environmentally
friendly industrial solvents.
Unlocking the subtle mysteries of molecular processes is the key
to creating and improving products and processes. Results of neutron
scattering experiments have long been relied upon to verify indirectly theories
about molecular-level processes. Computers, although useful for modeling
atoms and small molecules, lacked the power to simulate large molecules (e.g., polymers) and or complex processes involving many molecules on a
scale useful to industry.
Using the Intel Paragon XP/S 150 supercomputer and the special
codes we've developed, we can model complex molecular systems
of importance to industry. We start with first principles, entering data
about atoms and basic molecular interactions. By predicting a new
material's properties, perhaps even before the material has been created, we can
help industry develop and test new products more quickly and efficiently.
We are studying various properties of natural and synthetic materials at
a level of detail previously unimaginable. We plan to develop improved codes to aid in drug design and evaluate etching and
coating processes for producing microchips.
Thanks to supercomputers, computation has been elevated to
equal status with theory and experiment. Thus, ORNL and the UTK
have created the Joint Institute for Molecular-Based Engineering
and Science (JIMBES). Combining molecular-level computation
with results of neutron and X-ray scattering at ORNL, JIMBES offers a
new approach to product development for the world.
The research was supported by ORNL's Laboratory Directed R&D Program.
A proposal is made to construct a county landfill near your home.
You call a county commissioner and ask if drainage from the proposed landfill would pose a health hazard to your family. You may have identified
a complex environmental problem.
ORNL is playing a major role in helping to solve
complex environmental problems at local, state, and regional levels as part of the
newly established National Center for Environmental Decision
Making Research. This center can help decision makers identify an acceptable
landfill site by imparting information on successfully used tools and
lessons learned in similar situations elsewhere.
To direct the center, the National Science Foundation selected the
Joint Institute for Energy and Environment (JIEE), a collaborative
research institute involving staff from ORNL, TVA, and UTK, which administers
the center. Milton Russell, director of JIEE, professor of economics at
UTK, and a collaborating scientist at ORNL, is the center's director. ORNL's Robb Turner is deputy director.
The center assembles specialists who provide decision
makers nationwide with the information, techniques, and processes they need
to effectively and fairly solve environmental problems.
These specialists analyze processes that influence environmental decisions
and present the results in a form useful to decision makers. They glean
lessons from case studies involving environmental decision making
that may apply to other environmental issues. They develop a "toolkit"
to guide environmental decision makers facing different situations. They
are creating a national source of databases and other information that will
be available on the World Wide Web. The center interacts with citizens, leaders
in industry, and government decision makers through an outreach
program that includes workshops, publications, electronic media, residency
programs, conferences, and seminars.
The rationale for the center is that state and local officials and citizens
are increasingly being asked to render decisions on difficult
environmental issues requiring analysis and information not always
readily available. The center's work should result in simpler, faster, and less
costly techniques to help local officials make wiser and fairer decisions.
