SD EPSCoR will be soliciting Seed Grant proposals from researchers at the NSF EPSCoR Track-1 partner institutions. A total of $200,000 will be available in project year 4. High-impact proposals supporting NSF EPSCoR Track-1 goals and objectives will be solicited. Research proposals supporting transformative solutions or innovative uses of 2D materials and biofilms will be solicited as well as innovative STEM education, outreach, and diversity activities. It is anticipated that at least 4 awards for up to 12-months, October 1, 2022-September 30, 2023, will be made. Deadline will be 5 p.m. (MDT), Friday, July 29, 2022. Applicants must collaborate with a current Track-1 researcher on an application.
Proposals for high-risk, high reward biofilm research at the intersection of biofilms, 2D materials and big data will be solicited. Seed Grant funds are intended to:
- support innovative activities that will result in submission of proposals to federal agencies or private organizations, and
- allow individuals not currently supported by Track-1 funding to become involved in the Track-1 activities.
Graduate Student Awards for the current Track-1 project include the following:
- A Comparative Study of Pulmonary Cell Response and Toxicity Following Acute and Chronic Exposures of Graphene-Family Nanomaterials — Jordan A. Hoops and Sourav Verma, South Dakota School of Mines (Faculty Advisor: Dr. Timothy Brenza and Dr. Kenneth Benjamin) — The proposed work aims to study the acute and chronic inhalation exposures and evaluate long-term impacts of graphene-family nanomaterials (GFNs) on respiratory cell function and explore the mechanisms underlying its toxicity to develop a sound toxicology profile and exposure limit recommendation for GFNs. The objectives of this research are twofold: 1) Developing an in vitro model to assess chronic exposure of GFNs on respiratory cell functions, and 2) study the selective biomolecule such as surfactant protein’s interaction with GFNs using molecular dynamics (MD) to attain an atomistic level understanding of toxicity mechanism of graphene.

The membranes’ performance will be tested in a prototype anaerobic membrane bioreactor for wastewater treatment. The project team developed and conducted a hands-on experience for middle school girls in Rapid City.
- Raman Spectoscopic Analysis for Investigating Nitrogen Fixation Efficiency of Rhizobia in Soybeans — Athira Madhavan and Swastika Bera, South Dakota State University (Faculty Advisors: Sen Subramanian & Anamika Prasad) — The objective of the research is to characterize the nitrogen fixation efficiency of different Bradyrhizobia strains in soybeans by estimating the relative ureide abundance. The collaborative project involved plant science and mechanical engineering expertise.
- Genome Sequencing and Annotation of Eight Midwestern Soybean-Colonizing Bradyrhizobium Strains with Different Nitrogen-Fixing Capacities — Armaan Kaur Sandhu and Lilia Hernandez, South Dakota State University (Faculty Advisors: Sen Subramanian and Volker Brozel) — The objective of the research is to obtain assembled and annotated genomes for the eight Bradyrhizobium strains, facilitating the identification of key elements involved in competition for nodulation in soybean, as well as study of symbiotic properties. To achieve this, quality genomic DNA will be extracted of each of the eight Bradyrhizobium strains and full genome sequencing will be performed. The project involved the collaboration of microbiology, plant science and informatics groups.
- Two-Dimensional Materials for Low-Cost Sustainable Perovskite Photovoltaic Systems — Achyuth Ravilla and Md. Hasan-Ur Rahman, South Dakota School of Mines (Faculty Advisors: Ilke Celik and Venkataramana Gadhamshetty) — The objective of the research is to design an environmentally friendly and economically feasible perovskite solar cells, enabled by 2D material technology. The project also involves development and delivery of hands-on activities for middle and high school students on energy harvesting from sunlight and sustainability.
- Use of Novel Degradable Surface Coatings for Enhanced Biofilm Growth — Whytneigh Duffie and Cody Allen, South Dakota School of Mines (Faculty Advisor: Travis Walker) — The objective of the research is to determine if microbes will first attach to the surface of a sacrificial coating, and subsequently multiply as the material degrades so, upon completion of material degradation, the microbes are better attached to the metal surface resulting in significantly decreased biofouling. A provisional patent has been filed and an NSF I-Corps application is planned.
Year-3 Awards for the current Track-1 project include the following:
- Bio-Scrubber for Mine Ventilation Air Treatment — Dr. Purushotham Tukkaraja, South Dakota School of Mines, is designing and testing a 3D-printed biofilm mat framework for use in extremely harsh mining conditions and reduce toxic air pollutants from underground mining operations, maintaining the mine ventilation air quality. Collection of mine air and biofilm samples will be collected from the Sanford Underground Research Facility, laboratory-scale biology experiments including enrichment and growth of resilient biofilm mat, and testing under simulated mine ventilation conditions will be done.
- Materials and Manufacturing Education for the Next Generation — Katrina Donovan, South Dakota School of Mines, developed and is delivering a 4-week hybrid, virtual and in-person, course on 3D printing for teams of teacher/student teams. The objective is to prepare teachers and motivate the next generation of students to be innovators, creators and tool builders through developing the ability to perform computer aided design, constructing tools for additive manufacturing (3D printing), and leveraging an intuition for material properties.
- Influence of Two-Dimensional Coatings and Associated Biofilm on Zebra Mussel Attachment — Dr. David Waterman, South Dakota School of Mines, is laying the groundwork for development of a thorough mechanistic understanding of the interactions between substrate, 2D coating, conditioning film, biofilm, and macroinvertebrate adhesive proteins that can lead to development of 2D coatings to prevent macrofouling.
