Brookhaven National Laboratory is a multipurpose research institution funded primarily by the U.S. Department of Energy’s Office of Science. Located on the center of Long Island, New York, Brookhaven Lab brings world-class facilities and expertise to the most exciting and important questions in basic and applied science—from the birth of our universe to the sustainable energy technology of tomorrow. We operate cutting-edge large-scale facilities for studies in physics, chemistry, biology, medicine, applied science, and a wide range of advanced technologies. The Laboratory's almost 3,000 scientists, engineers, and support staff are joined each year by more than 4,000 visiting researchers from around the world. Our award-winning history, including seven Nobel Prizes, stretches back to 1947, and we continue to unravel mysteries from the nanoscale to the cosmic scale, and everything in between.

Organizational Overview

The Energy Frontier Research Center (EFRC) on Molten Salts in an Extreme Environment (MSEE) was recently funded at Brookhaven National Laboratory (BNL). Liquid molten salts (MS) are found as solvents of the fuel constituents and/or coolants in nuclear reactor technology.  Due to their nature as ionic fluids, MS have structural and dynamical correlations distinct from those of uncharged molecular or atomic liquids.  The scientific mission of MSEE is to provide fundamental atomic-level understanding of bulk and interfacial molten salts.  The Center will measure and predict the local and intermediate-range interactions, the structures and dynamics of molten salts in the bulk and at interfaces.  Specifically, the Center will develop and use in situ synchrotron x-ray spectroscopy, scattering and imaging techniques to understand interfacial and corrosion processes in MSEE.  X-ray measurements will be integrated with modeling approaches (i) to provide fundamental new information on surface ordering and dynamics of MS and (ii) to understand and predict non-equilibrium, metastable states formed during the reactions at interfaces.

Job ID # 1411 – Post-Doctoral Research Associate – Materials Characterization
The Nuclear Science and Technology Department has an opening for a Materials Characterization Post-Doctoral Research Associate in the Materials in a Radiation Environment Program Office. The successful candidate will design and execute experiments and perform data analysis to characterize bulk MS and MS/interfacial systems using x-ray synchrotron methods.  This interdisciplinary research will focus on the structural determination of solvents, solutes, and liquid-solid interfaces of MS.  This effort requires sampling handling at high temperatures and in corrosive conditions.  The candidate will collaborate with other members of the EFRC project on sample handling and hardware implementation and will perform the x-ray experiments together with beamline staff at the National Synchrotron Light Source-II (NSLS-II) at BNL.

The position requires a Ph.D. degree in chemistry, physics, materials science or a related field.  Basic knowledge and hands-on experience with one or more of the following synchrotron techniques:  X‑ray diffraction, reflectivity, spectroscopy, demonstrated problem-solving and troubleshooting skills in experimental science, self-motivation and ability to work in a diverse team environment, and excellent verbal and written communication skills is required.  Responsibilities include design, develop, and commission sample environments for synchrotron experiments on MS, perform x-ray diffraction, reflectivity and spectroscopy measurements on molten salt systems, participate in translating the experimental results into new scientific knowledge through the use advanced data analysis techniques, work on manuscript preparation, and develop and maintain safe practices and working conditions.  Other abilities should include: understanding the chemical and physical properties of high-temperature materials, experience in developing scientific apparatus for corrosive and/or high-temperature environments, knowledge of the chemistry and/or atomic structure of molten salt systems or actinides, and experience in applying and/or developing advanced data analysis software for X-ray diffraction, reflectivity, and/or spectroscopy.
