Investigating Grain Boundaries in BaCuS1-xSexF Using Impedance Spectroscopy

Creator:

Horgan, Briony

Abstract:

Impedance spectroscopy is a method of modeling materials with equivalent circuits to determine electrical properties, such as the resistivity and the dielectric constant. We explore impedance spectroscopy, both theoretically and experimentally through applying the method to samples of BaCuS1-xSexF. Grain boundary effects were dominant in the results, and although they...

Time Periodic Sand Ripples at the Oregon Coast

Creator:

Korn, Abraham

Abstract:

We consider development of sand ripples in shallow water flows which do not reach an equilibrium height but have a time-varying ripple height that slowly reaches a maximum value and then is quickly destroyed by the fluid. A simple scenario to explain the time periodic behavior of the sand ripples...
