Join us for this PSI seminar with guest speaker Dr. Joel Loh. Metamaterials are unique structures with light-matter interaction properties that are not seen in nature. The growing climate crisis has driven efforts to recycle and reduce our carbon emissions. This can be achieved by reducing the energy inputs or by seeking lower energetic pathways in common industrial reactions that create or reform chemical feedstock. I will discuss several examples of how metamaterial properties, associated with super-blackbody, impedance matching, bound-in-continuum states, and anapole resonances can be used to drive catalytic reactions. This is a young, emerging field with many unknowns in the interaction of metamaterial and its environment with heat, photo and/or electrical inputs. I will hypothesize about how conventional materials and surface characterization of the activation, adsorption, reaction and desorption stages of a reaction pathway can lead to insights in understanding these unique interactions. Understanding and designing these interactions will enable us to optimize metamaterials for a wide range important reactions, as well as benefit adjacent fields such as sensing and optics.

Biography: Joel Y. Y. Loh is a Dame Kathleen Ollernshaw Fellow (tenure-track) at the University of Manchester since 2023. He graduated with a bachelor’s degree in Material Science and Engineering at Nanyang Technological University, Singapore, and switched to the Electrical and Computer Engineering department in University of Toronto for his M.A.Sc. and Ph.D. He was presented with the Connaught Scholar Award and the Award for Excellence in Research at the Advanced Photovoltaics and Photodevices Facility. He has contributed to and has been the recipient of several grants from the Natural Sciences and Engineering Research Council of Canada. He is interested in developing metamaterials for energy applications and memristors for neuromorphic computing applications.
