Gregory Freihofer wins 2nd place at the SAMPE CAMX student paper competition
Will and Greg perform experiments at the Center of Nanoscale Materials, Argonne National Laboratory (CNM)
The trip to CNM w
as part of a collaboration with CNM scientists to develop nanoscale experiments to investigate the fundamentals of th
e stress sensing behavior for varying alumina nanoparticles. Using electron beam (E-beam) lithography, “nanobuckets” were created in Si wafers of various sizes and filled with an epoxy/alumina nanoparticle mixture.
The sample development will pave the way for experiments using an Atomic Force Microscope (AFM) within a confocal backscattering setup for measuring Photo-luminescence from the samples. These fundamental studies will investigate a range of particles, quantifying a multitude of important nano-composite properties such as interface strength, load transfer, and piezospectroscopic properties
