Terbium Ion Doping in Ca3Co4O9: A Step Towards High-Performance Thermoelectric Materials

Research

We have achieved the enhanced thermoelectric response in polycrystalline Ca3Co4O9 on doping Tb ions in the material. Specifically, a high figure of merit (ZT) of 0.74 at 800 K was observed for Ca2.5Tb0.5Co4O9.

Surface-Enhanced Fluorescence of Pyrene on Nanostructured Aluminum

Research

Both the absorption and emission of ultraviolet light by pyrene (PAH compound) are enhanced by more than 30-fold on nanostructured aluminum, compared to an equivalent control sample on sapphire (aluminum oxide).

Using Shape Memory Alloys for Active Terahertz Plasmonic Devices

Research

We show the first demonstration of shape memory alloys being used for active THz devices. The metal foil was found to reproducibly cycle between the two geometries over 100 times.

Hands-on Science After School

Education

Utah MRSEC establishes science and engineering afterschool clubs at community centers and schools serving predominately underrepresented minority (URM) students in those fields. The Education and Outreach team then hires and trains University of Utah undergraduates to lead the clubs and deliver hands-on activities each week.

Discovery of a New Line Defect in a Perovskite Oxide

Research

Defects, essentially locations in a crystal where the perfect arrangement of atoms is disturbed, are inherent in materials, and play a key role in their function.

Solution-Processed Indium Oxide Transistors: Printing Two-Dimensional Metals

Research

Transistors, the building blocks of all computer technologies, are currently based on semi-conductors such as silicon, manufactured using energy-intensive processes.

Spooling Instability of Self-Propelled Flexible Filaments

Cytoskeletal filaments with chemical motors attached are the basic elements in cells that enable biological motion. Computer simulation of model biomotive systems show that even systems with minimal ingredients are able to generate the kind of exotic nonequilibrium behavior observed in cells.

Photoinduced Plasticity In Cross-linked Polymer Networks

Researchers in the Soft Materials Research Center of the University of Colorado Boulder have employed dynamic covalent chemistry to make cross-links that can be controlled optically, enabling materials that can be softened or changed in shape by light.

MRSEC Members Teach the Public about Materials Science during the Wisconsin Science Festival

Education

Over the course of two days, the Wisconsin MRSEC presented exciting hands-on, research-inspired  materials science activities to over 1500 people during the 2016 Wisconsin Science Festival.  The 2016 Wisconsin Science Festival was the largest ever with over 250 events in 20 communities across Wisconsin.
