Research Collaboration Continues with Lewis University and Pall Corp.

Published: November 7, 2017.

The research group of Dr. Jason Keleher at Lewis University is entering its ninth year of collaboration with Pall Corporation, a global manufacturer of advanced filtration, purification and separation systems. The work provides key information with respect to filter media performance that will closely mimic the real-world customer applications, which can aid in the development of next generation filtration systems.

The most recent work by Lewis University undergraduates Cynthia Saucedo, Maria Salinas, Katie Wortman-Otto and research mentor Dr. Jason Keleher, associate professor and chair of chemistry, entitled “Exploring Non-Covalent Interactions at the Slurry/Filtration Media Interface Relevant to CMP Filtration Applications” was accepted and presented at the International Conference on Planarization held October 11 – 13, 2017 in Leuven, Belgium. More specifically the team has developed a suite of in-situ analytical techniques that can track subtle changes at the media/chemistry interface to provide mechanistic information about key interaction pathways.

As stated by Dr. Yeny Hudiono, Principal Scientist at Pall, “Pall’s long-standing collaboration with Lewis University and Dr. Keleher has been extremely beneficial to our understanding of the fundamental behavior of filtration medium in chemical mechanical planarization (CMP) applications, as well as other types of critical applications. We really have to applaud the efforts of the entire team at Lewis.”

Saucedo reflected on the experience, “Being able to interact with the research teams at Pall Corporation has given me the opportunity to solve challenging and industry-relevant problems, while really making the classroom science really come to life.”

Pall Corporation is a filtration, separation and purification leader providing solutions to meet the critical fluid management needs of customers across the broad spectrum of life sciences and industry. Pall works with customers to advance health, safety and environmentally responsible technologies. The company’s engineered products enable process and product innovation and minimize emissions and waste. For more information, please visit
