Electrocaloric Effect of Perovskite High Entropy Oxide Films

Y. Son and Susan E. Trolier-McKinstry, Penn State University
Pb(Hf0.2Zr0.2Ti0.2Nb0.2X0.2)O3, a high-entropy perovskite, undergoes an entropy-driven phase transformation when X=Mn while X=Al always contains minor second phases in bulk ceramics.

Ballistic Excitons and Surface Functionalization in a Superatomic Semiconductor

Roy, Delor, Nuckolls and Berkelbach, Columbia University
The transport of energy and information in semiconductors is limited by scattering between electronic carriers and lattice phonons, resulting in diffusive and  lossy  transport  that  curtails  all  semiconductor  technologies.

Big Idea: Understanding the Rules of Life

Leveraging the Polymer Glass Transition

A collaboration between the de Pablo, Rowan and Jaeger groups at the University of Chicago developed a novel class of suspensions with stimuli-responsive polymer particles to be able to transition reversibly between liquid to solid behavior in response to temperature,
