He identifies and shapes emerging strategic scientific and technological initiatives, and provides oversight of entrepreneurship and innovation activities at the University's Polsky Center for Entrepreneurship and Innovation. He also works with faculty, deans, and administrators to build global academic partnerships and international research collaborations while overseeing the University's international centers. Juan de Pablo provides leadership for the University's stewardship of two U.S. Department of Energy National Laboratories - Argonne and Fermilab - as institutions to advance science and technology in support of the nation's interest. He collaborates with other leaders in research and innovation to build programs and links between and among the national laboratories and the University, as well as the Marine Biological Laboratory. Working closely with President Paul Alivisatos, he plays an essential role in the University's partnership with the Department of Energy. ******* ******* "Control and Design of Active Liquid Crystals" Tuesday, April 5, 2022 3:00 p.m. - 4:15 p.m. FRNY G140 - Reception at 2:30 p.m. in Henson Atrium - Abstract: Understanding how internal activity leads to specific behaviors is important for the control and design of autonomous materials systems capable of delivering desired functionalities. Polymeric materials comprising mechano-chemically active components can undergo spontaneous structural rearrangements that generate internal stresses and motion. These stresses can be particularly large in the case of liquid crystalline polymers, where elasticity plays an important role on the structure of the underlying materials. This lecture will focus on the relationship between structure, activity, and motion in lyotropic liquid crystalline polymeric systems. More specifically, results will be presented for actin and tubulin suspensions, where activity is generated by protein motors. A distinctive feature of these biopolymers is that characteristic contour lengths can range from hundreds of nanometers to tens of microns, thereby making them amenable for study by optical microscopy. By relying on molecular and meso-scale models, it is possible to arrive at a comprehensive description of these suspensions that helps explain the connections between molecular structure, the formation and shape of distinct topological defects, activity, and defect dynamics. One of the outcomes of such a description is the realization that hydrodynamic interactions can in some cases exacerbate or mitigate the elasticity of the underlying materials, leading to non-intuitive phenomena that do not arise at equilibrium. By balancing such effects, these findings raise the possibility of controlling and designing functional materials where specific, macroscopic dynamical responses are engineered into a system to create function. ******* ******* Davidson School of Chemical Engineering<https://engineering.purdue.edu/ChE> Purdue University West Lafayette, IN 47907 (765) 494-4050<tel:+17654944050> (c) 2022 Purdue University<http://www.purdue.edu/purdue/disclaimer.html> All rights reserved An equal access/equal opportunity university<http://www.purdue.edu/purdue/ea_eou_statement.html>
