"How does my hard drive work?"

Andrew Berger, Michael Page, Shane White, Nandini Trivedi, Michelle McCombs, The Ohio State University
Graduate students at Ohio State's Center for Emergent Materials (Andrew Berger, Michael Page, Shane White) developed a demo illustrating how a computer hard drive works. This demo has been used at several outreach events and in school efforts through the Scientific Thinkers program and is currently under discussion with the Museum of Science in Boston for duplication there.

Chiral magnetism at oxide interfaces

Sumilan Banerjee, Onur Erten, Mohit Randeria, The Ohio State University
LaAlO3 and SrTiO3 are two well known non‐magnetic insulators, but when LaAlO3 is deposited on SrTiO3 to form a clean LaAlO3/SrTiO3 interface, the interface becomes an ultra‐thin sheet of conductor. Even more surprisingly, the interface exhibits unusual magnetic properties, but the origin of the observed interfacial magnetism is under debate.

Observation of the inverse spin Hall effect in ZnO thin films: An all-electrical approach to spin injection and detection

Megan C. Prestgard, Graduate Student, Materials Science and Engineering, University of Utah Ashutosh Tiwari, Associate Professor of Materials Science and Engineering, University of Utah
Discovery: We have observed a large inverse spin-Hall effect (ISHE) in ZnO films grown using Pulsed Laser Deposition. This discovery provides an entirely new means of measuring spin currents in semiconductors. Approach: Developed a novel device concept for the injection and detection of spin-polarized carriers.

Bioinspired Design of Reconfigurable, Anisometric and/or Patchy Particles

Daniel Milller*, Xiaoguang Wang*, Douglas Weibel*, Juan de Pablo^, Nicholas L. Abbott* *University of Wisconsin - Madison, ^University of Chicago
Guided by hierarchical materials design principles evolved by bacteria, which include the use of curvature-induced strain to dynamically position amphiphiles, proteins and other biomolecules within single cells, IRG3 of the Wisconsin MRSEC has recently recapitulated these design principles in synthetic LC systems. In one set of approaches, the IRG has explored the complex interplay of curvature strain, surface anchoring and topological defects within LC droplets to achieve the synthesis of

GaAs(1-y-z)P(y)Bi(z) - New Near Lattice-Matched Materials to GaAs

Susan E. Babcock*, April S. Brown^, Maria Losurdo**, Thomas F. Kuech*, Luke J. Mawst*, Dane Morgan* *University of Wisconsin - Madison, ^Duke University, **Institute of Inorganic Methodologies and Plasmas (IMIP), CNR, Bari, Italy
The IRG has developed a new material, GaAs1-y-zPyBiz, as an alternative to the nitride–based bismide materials, specifically GaAs1-y-zBiyNz. Alloying in both Bi and N complicates growth, since both elements are sparingly soluble in GaAs. GaAs1-yPy,
