Hydrogel Inks for Direct-Write 3D Printing
Abstract: Additive manufacturing (or 3D printing) has re-emerged into the spotlight in the last 5 years driven by the rapid progress in hardware and software.  Along with these advances, new materials are required to meet the demands of emerging technologies.  Herein, we present multi-stimuli-responsive hydrogels designed for direct-write 3D printing.  These materials are reversibly stimuli-responsive to temperature and pressure, and can ultimately undergo UV-initiated cross-linking.  The syntheses, characterization, and patterning of these materials will be presented.  The application of these polymer hydrogels toward catalytically active living materials and anatomical models for human tissue will also be discussed.

Bio: Alshakim Nelson is an Assistant Professor in the Department of Chemistry at the University of Washington. He received his PhD in organic chemistry from the University of California, Los Angeles in 2004, where he worked with Sir J. Fraser Stoddart on carbohydrate-containing polymers and macrocycles. He was then an NIH postdoctoral fellow at the California Institute of Technology working for Professor Robert Grubbs on olefin metathesis catalysts for the formation of supramolecular ensembles. Dr. Nelson joined IBM Almaden Research Center as a Research Staff Member in 2005, where he focuses on synthesizing building blocks that enable large area nanomanufacturing via self-assembly. His research interests also involved silicon-based polymers for lithographic applications, magnetic nanoparticles, directed self-assembly of nanoparticles, and hydrogen bonding block copolymers. Dr. Nelson has over 40 publications and 11 issued patents, and in 2011 he was designated as an IBM Master Inventor. He has also been recognized as an ACS PMSE Young Investigator in 2012 and a 2016 Kavli Fellow. His research group currently focuses on stimuli-responsive hydrogels for 3D printing.

Molecular Engineering and Sciences Seminar Series

This weekly seminar brings together students, faculty and invited guests from various disciplines across campus to explore current trends in molecular engineering and nanotechnology. It is a forum for active interdisciplinary discussions. These talks are open to the public and attract a diverse audience of students and faculty.…
