Characterization and engineering of self-assembly, dispersion, and emulsification 

(collaborators have included Eric Morrison, Hanseung Lee, Joe Zasadzinski. Vijay John (Tulane), Srini Raghavan (Maryland), Geoff Bothun (Rhode Island), Lee Penn, David Morse)

Our group has been active in several projects that capitalize on complementary microscopy techniques to understand the formation of micelles and nano-sized dispersions in surfactant systems. These projects typically involve collaboration with other faculty and with industrial collaborators who participate in a nonproprietary way through our NMP program. For instance, we have used cryogenic transmission and scanning electron to explain the nanostructure formation process steps, and sensitivity to process variables, in the formation of certain nanoparticles and in the formation of long-lived nanoscale oil-in-water dispersions. Our goal is to develop principles for the engineering of systems that develop nanostructures.

Our group has also studied dispersion conditions to help distinguish what are more effective dispersants. Our collaborative work to date has shed light on why it is that a specific mix of surfactants is particularly effective. Moreover, results to date suggest that microstructures (e.g., micelles, and possibly vesicles) can influence the dispersion process, both by stabilizing surfactants that would not otherwise penetrate the oil and also by influencing rates of transport to the newly-created surface during the dispersion process. 

With Dave Morse, an additional goal is to understand the rate limiting mechanisms when generating new surfactant-laden interfaces, such as in dispersion processes.  Molecular theory and simulation provide insights into the role of micelles in either accelerating or slowing the arrival of surfactant at new interface.

Characterization and Curing of coatings and modified surfaces

(collaborators have included Lorraine Francis and Greg Haugstad; and industrial fellows with IPrime member companies (including Boston Scientific, Ecolab, and Donaldson))

With Greg Haugstad and several Industrial Fellows in IPRIME,  projects have focused on curing and nanostructured and chemically treated surfaces, typically in wet or humid environments and at the micro- and nano- scale.  

With Lorraine Francis, several graduate students have investigated coating/curing systems with the goal of limiting stress development and micromolding pattern integrity while improving cure rate.

With Lee Penn, we have used analytical TEM to identify nanostructural reasons for rate limitations to solid/fluid reactions important for removing sulfates from mining waste processing, for the environmental protection of aquifers streams and lakes.

Sustainable, distributed, small scale ammonia production enabled by high temperature solid absorbent systems (collaborators have included Cussler, Dauenhauer, Reese, Daoutidis. Zhang, Malmali (TexasTech))

Our group has explored small-scale ammonia process with a novel design that uses a high temperature ammonia-selective absorbent at near-catalytic conditions to simplify the process. This absorbent captures and releases ammonia at temperatures and pressures like those used in conventional ammonia synthesis. With this development, we hope to assist synthesis of fertilizer at the farm and agricultural co-op level so that carbon footprint, transport limitations, and renewable energy sources can be addressed.  

With several collaborative projects supported by the Department of Energy and the State of Minnesota, ongoing work is exploring the use of ammonia absorbents in other applications, including storage.
