The Heavy Element Chemistry and Separation Sciences group in the Chemical Science and Engineering Division of Argonne National Laboratory is seeking applications for a postdoctoral research associate to conduct fundamental research in chemical separations with green solvents, including room temperature ionic liquids and deep eutectic solvents, with application to critical materials, including rare earths and lithium. The successful candidate will join a diverse team of experts to address challenging, fundamental questions in chemical separations, the answers to which will inform a more energy efficient and environmentally aware nation. The team includes staff and postdoctoral fellows with diverse backgrounds in inorganic, analytical and physical chemistry, as well as condensed matter physics. They will have the opportunity to work with the computational facilities and advanced instrumentation available at Argonne National Laboratory, including the Advanced Photon Source. The candidate will be expected to contribute experimental insights to the group’s efforts to understand the physical and chemical factors enabling low-energy separations, focusing on liquid-liquid extraction using nanostructured green solvents. As a contributor to a group effort, the candidate will have the opportunity to lead studies, including the preparation of manuscripts and the presentation of their research in a national forum. **Position Requirements** + A Ph.D. with 0 to 3 years of experience or equivalent in chemistry, chemical engineering, physics or a related field at the time of start date + Interest in the design and execution of all aspects of research addressing fundamental scientific questions, with accompanying excellent oral and written communication skills + Significant research experience with ionic liquids, deep eutectic solvents or chemical separations + Ability to model Argonne’s Core Values: Impact, Safety, Respect, Integrity, and Teamwork Preferred Qualifications Include: + Knowledge of solution thermodynamics + Experience with experimental characterization techniques applied to liquids and/or their interfaces, such as x-ray scattering and spectroscopy, NMR spectroscopy, absorbance spectroscopy, tensiometry of liquid interfaces, or Langmuir trough techniques + Experience with structural investigation of liquid interfaces, or ion adsorption at liquid interfaces + A basic understanding of chemical separations of metal ions **Job Family** Postdoctoral Family **Job Profile** Postdoctoral Appointee **Worker Type** Long-Term (Fixed Term) **Time Type** Full time _As an equal employment opportunity and affirmative action employer, and in accordance with our core values of impact, safety, respect, integrity and teamwork, Argonne National Laboratory is committed to a diverse and inclusive workplace that fosters collaborative scientific discovery and innovation.
