Ionic micellar assemblies have been simulated over μs time scales on GPUs (image on cover of Soft Matter).

Manipulating the topology of iso-frequency surface provides a new approach for control of light-matter interaction. This is demonstrated using anisotropic metamaterials consisting of metal-dielectric layers. 

  Giant spin-Seebeck effect could provide power from waste heat

In July, 2012, the UW-MRSEC hosted graduate students from the University of Puerto Rico Mayaguez. While in Madison, Wisconsin the students performed their Science on Wheels (Ciencias en Ruedas) show at the Wisconsin Institutes for Discovery on the UW-Madison campus. The show teaches students about chemistry and physics using loud, exciting, highly visual content including explosions, water cannons, liquid nitrogen balloons and more.

Assembling microscopic particles into macroscopic structures can open new pathways for producing complex materials that cannot be produced by lithographic methods. Although several methods for assembling colloidal particles exist, including controlled drying, ionic interactions, and dipolar interactions, a general pathway for producing a wider variety of structures remains a fundamental challenge.  Here a versatile colloidal assembly system is demonstrated in which the design rules can be tuned to yield over 20 different

Utah MRSEC sponsored 10 undergrads to work with faculty and graduate student mentors in their labs for a 9-week research program. Research opportunities for Utah MRSEC REU students are of an interdisciplinary focus on topics such as plasmonic metamaterials, and spin effects in organic LEDs & solar cells. Researchers and selected students are from fields such as materials science, electrical engineering, physics, chemistry and applied math.  

Objective: Develop and characterize OLEDs based on spin-aligned carrier injection of which electro-luminescence (EL) is controlled by magnetic field. Approach: Use ferromagnetic cathode and anode that work as bipolar spin- valve injecting both electrons and holes into a deuterated π-conjugated polymer.
