    Textbook publisher Wiley has just released the second edition of Protein Chromatography: Process Development and Scale-Up, co-written by UVA Engineering’s Lawrence R. Quarles Professor of Chemical Engineering Giorgio Carta. First published in 2010, the book warranted an update 10 years later.

    Carta, an internationally recognized leader in preparative and process chromatography education and research, wrote the book with biotechnology professor Alois Jungbauer of the University of Natural Resources and Life Sciences in Vienna, Austria. Chromatography encompasses techniques for separating mixtures of chemical or biological substances into individual components.

    The text partially grew out of a two-week short course Carta and Jungbauer developed and taught for many years at their respective universities. The course and the book were designed for engineers, scientists and technical managers, as well as students, seeking a deeper understanding of chromatographic processes and their scale-up, particularly in pharmaceutical manufacturing where achieving purity of drug ingredients is critically important.

    Carta noted that many advances occurred in the field since the first edition came out. The update includes work by several alumni who have trained in his UVA lab over the years, he said.

    Wiley describes the book as “an all-in-one practical guide on how to efficiently use chromatographic separation methods,” noting, “this fully updated and revised new edition offers comprehensive coverage of continuous chromatography and provides readers with many relevant examples from the biopharmaceutical industry.”

    Mara K. Kuenen, a Ph.D. student in assistant professor Rachel Letteri’s research group, has won the 2020 Chemical Engineering DuPont Student Safety Award.

    DuPont provided a gift to fund the annual award to promote safety in research labs. Students can submit a proposal for improving safety or apply for the award based on ideas that have been implemented.

    Kuenen’s fellow Ph.D. student Stephanie Guthrie nominated her to the Department of Chemical Engineering Safety and Security Committee, commending Kuenen’s commitment to laboratory safety, teaching others about safe working practices — particularly with regard to polymer materials — and to communicating hazards and hazard mitigation strategies with her colleagues, including undergraduate students.

    In an email to Kuenen notifying her of the award, Geoffrey M. Geise and George Prpich, faculty members on the committee that made the selection, cited Guthrie’s nomination.

    Guthrie noted Kuenen’s commitment to a culture of laboratory safety, which she wrote is “based on understanding safety hazards and their mitigation — not merely on enforcement of a fixed set of rules.”

    “It is clear that your efforts have made a positive impact on several of your colleagues and ChE students at UVA,” Geise and Prpich wrote to Kuenen.

    The award includes a $1,000 cash prize and an invitation to speak during the department’s annual safety seminar in August, to which Kuenen has said she is happy to contribute.

    “I’m honored that Stephanie took the time to nominate me,” Kuenen said. “And, I’m glad that I have contributed to the safety culture for the students in the undergrad lab.”

    Geise Group’s Undergraduate Battery Research Project Gets Lift From Virginia Space Grant Consortium

    April 03, 2020

    The Virginia Space Grant Consortium recently awarded the Geise Research Group a grant to support an undergraduate research project. Under the direction and mentorship of assistant professor of chemical engineering Geoffrey M. Geise, undergraduate students will work with graduate researchers in Geise’s lab to investigate a new approach to designing polymer electrolyte membranes to make lithium-sulfur (Li-S) batteries viable for space applications. The project will focus on engineering advanced membranes to be used as battery separators in extreme environments. Batteries made using advanced technologies are expected to be a critical part of addressing space-based energy storage needs associated with NASA’s Artemis Mission for moon and Mars exploration.
