Synthesis of a Family of 2D Coordination Polymers using Hexaaminobenzene as the Building Block

Nabajit Lahiri, Neda Lotfizadeh, Ryuichi Tsuchikawa, Vikram Deshpande and Janis Louie; University of Utah
Since the discovery of Graphene, there has been a significant interest in the search of new 2D materials which would show similar interesting properties such as electrical and thermal conductivity, superconductivity, and topological gap.
A thermal gradient is applied to the permalloy (Ni81Fe19) ferromagnetic thin film, while the Sagnac interferometer microscope watches for subtle changes in magnetization due to spin currents in the film. This non-contact optical technique allows the magnetization and/or thermal gradient to be in-plane or out-of-plane for studying the underlying spin-Seebeck physics.

“Optical Detection of Transverse Spin-Seebeck Effect in Permalloy Films using Sagnac Interferometer Microscopy”

R. McLauglin, D. Sun, and Z.V. Vardeny; University of Utah
The field of spintronics, which involves the design of novel electronic devices that utilize the spin of electrons, requires researchers to develop a robust source of spin-polarized currents to fuel future technology.

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

Shrikant Saini, Yinong Yin, Ashutosh Tiwari; University of Utah
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

Danielle Montanari, Joel Harris, Steve Blair; University of Utah
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

Barun Gupta, Shashank Pandey, Anjali Nahata, Ting Zhang, Sivaraman Guruswamy and Ajay Nahata; University of Utah
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

Chelsey Short, University of Utah
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

Bharat Jalan, Renata Wentzcovitch, Andre Mkhoyan University of Minnesota
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.

Spooling Instability of Self-Propelled Flexible Filaments

Meredith Betterton, Matthew Glaser University of  Colorado Boulder
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.
