Jobbeschreibung

Overview:

We are seeking a highly motivated Postdoctoral Research Associate in Organic Chemistry and/or Critical Materials Separation Science to develop next-generation ligands and functionalized sorbents for the selective extraction and recovery of gallium (Ga), germanium (Ge), and other critical minerals from complex zinc-processing feedstocks. The successful candidate will conduct organic synthesis, materials characterization, solvent extraction, and solid-phase separation studies to advance sustainable critical mineral recovery technologies. This position resides in the Nanomaterials Chemistry Group in the Separations and Polymer Chemistry Section, Chemical Sciences Division, Physical Sciences Directorate, at Oak Ridge National Laboratory (ORNL).

As part of our research team, you will be responsible for delivering high impact research results to advance the work on Gallium and Germanium separations. You will be very closely working with specialists in synthesis, separations chemistry, radiochemistry, theory, spectroscopy, and materials characterization. This project will develop materials and processing technologies that will result in a transformational improvement in separation and recovery methods for Gallium and Germanium.

Major Duties/Responsibilities:

• Design and synthesize organic ligands, functionalization of resins, polymers.
• Design and execute adsorption based solid-liquid and liquid-liquid separation experiments to meet project goals
• Use analytical techniques such as NMR, MS, FT-IR, TGA, DSC, XRD, BET, SEM for characterization.
• Perform ion separation experiments, use ICP to determine ion concentrations
• Collaborate with ORNL staff, University collaborators, Industry partners who are involved in the project
• Participate in project planning and execution
• Present and report research results at the project, group, PI meetings and national conferences
• Publish scientific results in peer-reviewed journals in a timely manner
• Ensure compliance with environment, safety, health and quality program requirements
• Maintain strong dedication to the implementation and perpetuation of values and ethics
• Deliver ORNL’s mission by aligning behaviors, priorities, and interactions with our core values of Impact, Integrity, Teamwork, Safety, and Service. Promote equal opportunity by fostering a respectful workplace – in how we treat one another, work together, and measure success.

Basic Qualifications:

• Ph.D. in organic or inorganic or polymer chemistry, materials science or a related field completed within the last 5 years.

Preferred Qualifications:

• Background in separations chemistry of metal ions, most desirably experience with Gallium and/or transition metals/lanthanides and experience with electrochemical separation is a plus
• Experience in ligand synthesis, functionalization of resins or polymers.
• Experience with sorbent extraction, adsorption, or packed-column systems for separation and use of appropriate analytical techniques such as ICP-OES or ICP-MS
• Ability to function well in a fast-paced research environment, set priorities to accomplish multiple tasks within deadlines, and adapt to ever changing needs
• Hands-on experience designing, synthesizing, characterizing, and evaluating materials for separation applications
• A strong track record of productive and creative research proven by publications in peer-reviewed journals
• Excellent written and oral communication skills.
• Motivated self-starter with the ability to work independently and to participate creatively in collaborative teams across the laboratory.
• Ability to function well in a fast-paced research environment, set priorities to accomplish multiple tasks within deadlines, and adapt to ever changing needs.

Special Requirements:

• Applicants cannot have received their Ph.D. more than five years prior to the date of application and must complete all degree requirements before starting their appointment. The appointment length will be up to 24 months with the potential for extension. Initial appointments and extensions are subject to performance and availability of funding.
• This position requires the ability to obtain and maintain an HSPD-12 PIV badge.

For employment at Oak Ridge National Laboratory (ORNL), a Real ID compliant form of identification will be required. Additionally, ORNL is subject to Department of Energy (DOE) access restrictions. All employees must also be able to obtain and maintain a federal Personal Identity Verification (PIV) card as mandated by Homeland Security Presidential Directive 12 (HSPD-12) and Department of Energy (DOE) Order 473.1A, which requires a favorable post-employment background investigation.

To obtain this credential, new employees must successfully complete and pass a Federal Tier 1 background check investigation. This investigation includes a declaration of illegal drug activities, including use, supply, possession, or manufacture within the last year. This includes marijuana and cannabis derivatives, which are still considered illegal under federal law, regardless of state laws.

For foreign national candidates:

If you have not resided in the U.S. for three consecutive years, you are not eligible for the PIV credential and instead will need to obtain a favorable Local Site Specific Only (LSSO) risk determination to maintain employment. Once you meet the three-year residency requirement, you will be required to obtain a PIV credential to maintain employment.
