The wide range of instrumentation within the University of Wisconsin MRSEC Shared Instrumentation Facilities (UW-MRSEC SIF) can now be accessed by academic and industry users around the nation via the Materials Research Facilities Network (MFRN.org). A Significant new addition over the past year is a Cameca LEAP 3000 Si ATOM Probe.
Creating aligned arrays of high purity (>99.9%) semiconducting single-walled carbon nanotubes (s-SWCNTs) over a large area has been a significant challenge in materials synthesis.
General Overview: Researchers at the Wisconsin MRSEC are working to develop sensors that can detect toxic substances near a single cell by exploiting the unique properties of liquid crystals (LC). LCs are materials that combine physical properties of both l
General Overview: The Wisconsin MRSEC is investigating innovative methods to incorporate a greatly expanded diversity of atom types into semiconductors, thus yielding materials with a new range of electronic properties.
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 sc
Simulations of a model for microtubule(MT)-based active nematics capture experimentally observed defect dynamics. The image on the right shows three sequential images from experimental system in which +½ and -½ defects are created through a bending stability and subsequently separate.
While conventional materials are assembled from inanimate building blocks, we are exploring the behavior of soft materials in which the constituent components consume energy and spontaneously coordinate their microscopic behavior and form novel materials such as active gels, crawling emulsion droplets, and living liquid crystals.
Electrons in epitaxial graphene nanoribbons travel unimpeded at high speed for large distances, so that they are ideally suited for graphene electronics.
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.
