MEAM Seminar: “Assembly Engineering of Patchy Particles into Complex Structures, and Beyond”
January 18, 2022 at 10:00 AM - 11:30 AM
The ability to predict, design and make the perfect material with just the right properties to do what we want, how we want, and when we want is the holy grail of materials research. Such “materials on demand” require control over thermodynamics, kinetics, nonequilibrium behavior, and structure across many length and time scales. With continuing advances in computer simulation capabilities, we have never been closer to the goal, but many challenges – and opportunities – remain. Many of those are at the boundaries of the subfields of materials research, where ideas from one area spur advances in others, and where computational tools and concepts are transferable across domains and scales. At the same time, foundational understanding at one scale can help understand new discoveries at different scales, regardless of the nature of the material and the forces holding it together. In this seminar, we show how atomic and molecular crystal structures – made possible by chemical bonds – can be realized for nanoparticles and colloids via enthalpic and entropic bonds. We show how these bonds can be designed and engineered for self-assembly.

Sharon C. Glotzer is the John W. Cahn Distinguished University Professor at the University of Michigan, Ann Arbor, the Stuart W. Churchill Collegiate Professor of Chemical Engineering, and the Anthony C. Lembke Department Chair of Chemical Engineering. She is also Professor of Materials Science and Engineering, Physics, Applied Physics, and Macromolecular Science and Engineering. She is a member of NAE, NAS, and the American Academy of Arts and Sciences. She is a fellow of the AAAS, APS, AIChE, MRS and RSC. She is currently a Simons Investigator, and the recipient of numerous other awards and honors, including the 2019 Aneesur Rahman Prize for Computational Physics from the American Physical Society; the 2018 Nanoscale Science and Engineering Forum Award and the 2016 Alpha Chi Sigma Award, both from the American Institute of Chemical Engineers; and the 2019 Fred Kavli Distinguished Lectureship in Materials Science and the 2014 MRS Medal, both from the Materials Research Society. Her research on computational assembly science and engineering aims toward predictive materials design of colloidal and soft matter: using computation, geometrical concepts, and statistical mechanics, her research group seeks to understand complex behavior emerging from simple rules and forces, and they use that knowledge to design new classes of materials. Glotzer’s group also develops and disseminates powerful open-source software including the particle simulation toolkit, HOOMD-blue, which allows for fast molecular simulation of materials on graphics processors, the signac framework for data and workflow management, and several analysis and visualization tools.
