The project will establish the knowledge base and design principles as a framework for developing and manufacturing...
- This $597,550 Project Grant award from the National Science Foundation's (NSF) Engineering program (CFDA 47.041) supports the development of self-biased microparticles to increase reaction rates in microbial electrochemistry. The project aims to create tiny particles that combine solar-powered electronics with bacterial activity, accelerating biological reactions for wastewater treatment, energy production, and environmental monitoring. The award recipient, the Regents of the University of...
- This $525,181 Project Grant from the National Science Foundation's Engineering program (CFDA 47.041) will fund research at North Carolina State University to explore harnessing soil microbes to improve soil supporting civil infrastructure. The university will identify active microbial communities in relevant soil microcosms and manipulate microcosm geochemistry to induce byproducts like mineral precipitation or gas generation. An integrated meta-omics approach will characterize microbial...
- This Project Grant award of $183,926 from the National Science Foundation's (NSF) Engineering program (CFDA 47.041) will support research at the California Institute of Technology (Caltech) to investigate the transport and collective behavior of microswimmers, such as bacteria, in porous media. The research will use 3D printing to fabricate porous environments and microscopy to observe how bacteria move through these environments. This will reveal how the motion and self-organization of bacteria...
- This three-year, $335,860 project grant from the National Science Foundation's Division of Chemical, Bioengineering, Environmental, and Transport Systems aims to develop strategies to enhance bioremediation of toxic chemical soil contamination. Specifically, the principal investigator at the State University of New York at Buffalo will investigate using chemical gradients to accelerate the transport of bacteria through soil matrices toward contamination sites. The research will experimentally...
- The National Science Foundation (NSF) awarded a $199,841 Project Grant to the Regents of the University of Minnesota, Duluth under the agency's Engineering program (CFDA 47.041). The purpose of this 2-year project, starting March 15, 2024, is to evaluate the effects of urban soil profiles and water infrastructure on surface-subsurface hydrologic processes in urban watersheds. The research aims to improve urban hydrologic models and quantify the costs/benefits of infrastructure rehabilitation...
This Project Grant award from the National Science Foundation (NSF) Engineering program (CFDA 47.041) provides $340,743 to the Regents of the University of Minnesota to conduct collaborative research on how microbial biosurfactants impact mass transport in unsaturated porous media. The project aims to: 1) quantify how time-dependent biosurfactant production alters transport behavior in two-dimensional porous systems; 2) characterize feedback loops between biosurfactant-induced flow, solute transport, and bacterial migration; and 3) measure and model biosurfactant-driven transport processes in three-dimensional porous media. The research utilizes innovative visualization experiments paired with advanced multiscale models to reveal the impact of biosurfactants on fluid and dissolved chemical transport in porous media like soils. This work could support improved soil remediation strategies, more sustainable agricultural practices, and new methods to manage the spread of harmful bacteria. The project also promotes STEM education and outreach activities.
