Postdoctoral Research Associate in Picosecond Radiation Chemistry

Job ID 2765 Date posted 08/13/2021

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. Brookhaven is operated and managed by Brookhaven Science Associates, which was founded by the Research Foundation for the State University of New York on behalf of Stony Brook University, and Battelle, a nonprofit applied science and technology organization.

Organizational Overview
Researchers in Brookhaven's Chemistry Division (https://www.bnl.gov/chemistry) seek to understand and control chemical systems to develop clean energy solutions for national needs.  The Electron- and Photo-Induced Processes (EPIP) Group (https://www.bnl.gov/chemistry/epip/) is a leader in the application of both photoexcitation and ionization by short pulses of fast electrons to investigate fundamental chemical problems relevant to the production and efficient use of energy and thus obtaining unique insights not attainable with other techniques. These studies may play an important role in the development of safer, more effective, and environmentally beneficial processes for the chemical conversion of solar energy and advanced nuclear fuel cycles. The group utilizes the cutting edge tools within it’s Accelerator Center for Energy Research (ACER, https://www.bnl.gov/chemistry/epip/instrumentation.php), most prominently the Laser Electron Accelerator Facility (LEAF).  LEAF provides 9 MeV, 10 picosecond pulsed radiolysis with a wide variety of time-resolved detection methods, including transient absorption from the UV to mid-IR, as well as microwave conductivity.

Position Description
The postdoctoral research associate will be responsible for fundamental radiation chemistry experiments to elucidate the nature and reactivity of pre-solvated excess charges (holes and electrons) generated by radiolysis. Such ultrafast processes that occur following radiolysis are critical for determining product formation and understanding them is essential for controlling and directing the ultimate impacts of radiation. Pioneering work in our program established that, contrary to expectation, holes in organic media exhibit surprising ultrafast reactivity prior to solvation, much like that previously observed for electrons in several solvents. Mechanisms of pre-solvated electron reactivity are not yet well established, and those of pre-solvated holes are unexplored. The focus of this position is to expand our knowledge of these species and their reactivity in a broad range of non-aqueous media with diverse properties. The associate will take a lead role in experiment design, sample preparation, data collection, analysis, and planning for future work.  Research will primarily utilize our group’s 9 MeV, 10 ps, Laser Electron Accelerator Facility (LEAF) combined with the unique Optical-Fiber Single-Shot (OFSS) detection system, with opportunities to contribute to their further refinement. Occasional travel to conferences to present results.

Essential Duties and Responsibilities:
• Participate in experiment planning, execution, translation of results into new scientific knowledge, and identification of new directions.
• Manuscript preparation.
• Contribute to improvement of OFSS transient absorption spectroscopy and related sample handling as needed.
• Develop and maintain safe practices and working conditions.

Position Requirements

Required Knowledge, Skills and Abilities:
• Ph.D. in chemistry, physics, or a related field.
• Experience with wet chemistry techniques and sample characterization under inert conditions.
• Self-motivated and ability to work in a diverse team environment.
• Excellent verbal and written communication skills.

Preferred Knowledge, Skills and Abilities:
• Radiation chemistry, photochemistry or a related field.
• Experience using pulse radiolysis, and/or transient absorption spectroscopy.
• Kinetic modeling, thermodynamics, electron transfer.
• Familiarity with computational chemistry techniques.
• Demonstrated problem-solving skills in the laboratory.
• Experience designing, building, and/or modifying experimental apparatus.
• Ability to use and modify LabView data-acquisition programs.
