Today’s Briefing:
RESEARCH: In a new study, chemical and biological engineering professor Sujit Datta and fifth-year graduate student Christopher Browne discovered why certain fluids — namely, polymer solutions that consist of very large molecules — increase in flow resistance when migrating under pressure through various porous mediums, a question that has perplexed researchers for more than half a century.
To shine a light on the mechanisms at work, they devised a method of visualizing the movement of polymer solutions as they passed through porous substances. The model they created involved rocks, transparent polymer solutions, and fluorescent dyes, among other elements that helped them visualize the turbulence of the polymer solution-porous substance interactions.
“The new understanding of how and when these chaotic flows arise in porous media provided by our work can thus help to inform the design of fluids and selection of operating conditions for groundwater remediation processes,” said Datta in an interview with the ‘Prince.’

NEW EXHIBIT: Toni Morrison, a former Robert F. Goheen Professor in the Humanities who passed away in 2019, will be honored through an exhibition by the Princeton University Library. The exhibition, titled “Sites of Memory: The Archival World of Toni Morrison,” will open in spring 2023.
In the library’s statement about the exhibition, Assistant Professor of African American Studies and English Autumn Womack wrote, “this exhibit follows the route mapped by the collection itself as it illuminates previously unknown aspects of Morrison’s life and practice, and reveals new ways of understanding seemingly familiar texts and events.”
The exhibit will work with the McCarter Theatre to bring three visiting artists to campus and will have undergraduate and graduate courses to implement the exhibit into the curriculum.
