Refreshments in PHY 313 starting at 3:30 pm
Neutrons are uniquely sensitive to protium and hydrogen’s other stable isotope, deuterium. This differential sensitivity to hydrogen and deuterium makes neutrons especially useful for the study of hydrogen-rich biological materials. For example, the judicious substitution of hydrogen for deuterium enables researchers to selectively tune which parts of a biological system are “seen” by neutrons. In other words, one can highlight or nullify the scattering from particular parts of, for example, a protein, a drug delivery system, or even an entire living cell. Importantly, this molecular focus is achieved through isotopic substitution rather than the use of extrinsic probes, which in certain cases are known to induce structural artifacts. During the seminar, I will discuss how we combine neutrons, computer simulations and sample development to address current issues in the areas of soft materials and model membranes.
The University of Waterloo acknowledges that much of our work takes place on the traditional territory of the Neutral, Anishinaabeg and Haudenosaunee peoples. Our main campus is situated on the Haldimand Tract, the land granted to the Six Nations that includes six miles on each side of the Grand River. Our active work toward reconciliation takes place across our campuses through research, learning, teaching, and community building, and is centralized within our Indigenous Initiatives Office.
