High School Students Synthesize Graphene by Chemical Vapor Deposition
Members
of the UW MRSEC Interdisciplinary Education Group (IEG) collaborated with MRSEC
researchers to develop a laboratory method that enables students to synthesize
research quality graphene
by CVD. The method uses safe,
inexpensive equipment and reagents so the synthesis can be performed in a high
school classroom. To date, the IEG has
led the activity with six groups of middle and high school students during
field trips at the University of Wisconsin Discovery Center. A manuscript describing the protocol is

Engineering Cellular Response Using Nanopatterned Bulk Metallic Glass (BMG)
Biomaterials implanted in the body evoke a “Foreign body response” which results in encapsulation of the material in a collagen-rich protein capsule. Fibroblast cells, which produce collagen, mediate this process that leads to biomaterial rejection / device failure in vivo. Surface nanotopography of BMGs can be used to engineer fibroblast-material interactions.

Enzyme Molecules as Nanomotors
MRSEC researchers have recently discovered that enzymes - molecules that catalyze chemical reactions in cells - move during the reaction. Although this property is well known for motor proteins, it has not been previously known that movement is a general consequence of enzymatic reactions. This movement depends on the concentration of the enzyme's substrate (the fuel for its reaction) and causes individual enzyme molecules t

MRSEC / SCOPE
During the academic year, F08 - S09, Olin undergraduates Sean Calvo, Caitlin Greeley, Stephani Gulbrandsen, and Leif Jentoft designed, built, and tested a flexible automated microscopy platform capable of imaging an area up to 100mm x 100mm with a resolution of 10 microns at 4.8 second per square mm. It reduces the cost of performing microfluidics research and increases the speed by allowing researchers to easily reconfigure and expand the system to their changing needs.

Intramolecular Exciton Transport in Conjugated Polymers
Using a series of acceptor-polymer-acceptor triads, IRG-2 investigators have measured intramolecular exciton diffusion in poly-3(hexylthiophene) (P3HT) for the first time.

Sharp signatures of fractionalized excitations in Kitaev spin liquids
Researchers have theoretically shown that distinct signs of Majorana excitations can be found in the Kitaev honeycomb model when a perpendicular magnetic field is applied. These unique features appear in what are called two-spin-flip excitations. The findings suggest that techniques like nonlinear THz spectroscopy could help detect these signatures in materials that are being studied as spin liquids. This work advances the understanding of quantum matter in these complex systems.
