Refining the r-process Described by Theoretical Models Research Advisor: Dr. Paul DeYoung Where did all of the heavy elements originate? The rapid neutron capture process (r-process), currently only characterized by theoretical calculations, model the nuclear reactions that lead to heavier nuclei in intense astrophysical locations such as supernovas. Experimenting with the few reactions reproducible on […]

Impact of the Ferroelectric Polarization State on Conductivity Through Thin-film SrTiO3/Si Heterostructures Research Advisor: Dr. Joshua Veazey Certain thin-film ferroelectric oxide-semiconductor heterostructures allow for reversible, local changes in conductivity, with potential applications including non-volatile memory devices. Force microscopy techniques were used to investigate the impact of the ferroelectric polarization state on local conductive properties of […]

Development of a Novel Method to Measure Per- and Polyfluoralkyl Substances in Paper and Textiles Research Advisor: Dr. Paul DeYoung and Dr. Graham Peaslee Per- and polyfluoroalkyl substances (PFASs) are chemical compounds used as powerful, long-lived surfactants in many consumer products. Because of the environmental persistence of PFASs, their ability to bioaccumulate, and their suspected […]
