Postdoctoral Fellow (PREP0004130) Full-time

Postdoctoral Fellow

This position is part of the National Institute of Standards and Technology (NIST) Professional Research Experience Program (PREP). NIST recognizes that its research staff may wish to collaborate with researchers at academic institutions on specific projects of mutual interest, thus requires that such institutions must be the recipient of a PREP award. The PREP program requires staff from a wide range of backgrounds to work on scientific research in many areas. Employees in this position will perform technical work that underpins the scientific research of the collaboration.

Research Title: Materials Characterization of Electronic Scrap Post-Doctoral Researcher

The work will entail:

The growing demand for critical minerals has highlighted the need for a more diverse and secure supply chain. The traditional linear model of resource extraction, processing, use, and disposal is subject to supply chain risks and results in a significant loss of critical minerals from the economy. As a result, there is increasing interest in transitioning to a more circular economy, where materials are recovered and reused at the end-of-life through recycling and other strategies. This shift has significant implications for the management of electronic scrap (e-scrap), which is a valuable source of critical minerals such as rare earth elements, lithium, and other key materials.

Current e-scrap recycling practices involve device shredding and separation of bulk materials (steel, aluminum, plastics, etc.). Many critical minerals and precious metals are not recovered in current processes, and to do so requires an improved understanding of where they end up in the recycling system. In this study, we're aiming to characterize the bulk separated material streams provided by e-scrap recyclers to understand elemental compositions and identify opportunities for recycling system improvements. In that effort, we seek a post-doctoral researcher with wet chemistry experience to support laboratory work, data analysis, and information dissemination. The researcher will work with an interdisciplinary NIST team in applying multiple analytical methodologies, including neutron activation analysis, XRF, and ICP-MS and OES, among others, as well as document and report findings. The ideal candidate would have prior experience working in laboratory setting with a good understanding of laboratory procedures, laboratory safety, and knowledge of critical mineral analyses.

Key responsibilities will include but are not limited to:

• Conduct literature review and stakeholder engagement to inform project development and identify gaps.
• Preparing samples for analyses using techniques such as milling, grinding, and microwave assisted acid digestion.
• Developing bulk and trace analytical elemental quantification methods with ICP-OES and nuclear analytical methods.
• Executing measurements using developed methods, analyzing data, and interpreting results to draw meaningful conclusions.
• Disseminating research findings through peer-reviewed publication(s), technical report(s), and/or oral presentation(s).
• Ensuring compliance with institutional safety protocols and requirements.

Qualifications:

• PhD in Chemistry, Chemical Engineering or Materials Science (or a related field with equivalent skills and experience).
• Experience with microwave acid digestion, ICP-OES, and analysis of critical minerals.
• Strong oral and written communication skills, with the ability to effectively convey complex research findings to complex audiences.
• A demonstrated track record of conducting independent and collaborative research in a multidisciplinary team environment, with a strong ability to meet project deliverables and milestones.
• A highly motivated and proactive approach to scientific problem solving, as evidenced by a strong publication record and letters of recommendation.
• A commitment to enforcing and adhering to safety protocols and requirements.
• Willingness to travel.
• Comfortable working with large volumes of hazardous chemicals, radioactive materials, and under radiological conditions.
