Filaments in the cytoplasm that constitute a three dimensional cytoskeleton are formed by polymerization of the protein actin, which is initiated at distinct sites near the cell membrane.   Negatively charged lipids in

The Nebraska MRSEC Professor/Student Pairs Program brings in a professor and a student from non-research intensive four-year institutions to conduct research with Nebraska MRSEC scientists. The goal is to offer a research experience which benefits both the participants and the MRSEC projects.

Ferroelectrics comprise an important group of materials, which are characterized by a permanent electric polarization. This polarization can be switched which provides a possibility of using ferroelectrics in data storage and memory devices. Typically, polarization is switched by the application of the external electric field. Nebraska MRSEC researchers have shown that polarization can be switched by purely mechanical means: simply by pushing the tip of a scanning probe microscope against the ferroelectric

Using the expertise in nanoparticle synthesis and assembly built up in IRG 3, a MRSEC team comprised of members of the Jaeger and Talapin groups collaborated with Xiao-Min Lin and Jeffrey Guest at Argonne’s Center for Nanoscale Materials and John Sader from the University of Melbourne to develop the first completely self-assembled nano-mechanical resonator. It forms when a  nanoparticle monolayer drapes itself over a hole several microns in diameter to produce a 10nm thin, freestanding membrane that vibrates in the MHz range (transmission electron microscope images shown in left inset).

Discovery: A class of 2D covalent organic framework made of triphenyl- metal compounds are found to be topological insulators exhibiting robust nontrivial topological edge states. Approach: Predictive First-principles band structure and band topology calculations.

We demonstrated an oxide-based TFT using electrochromic WO3 as the channel

  The lack of fundamental understanding of the role of oxygen in non-water based electrolytes significantly hinders the development of rechargeable lithium-air batteries.  This IRG has developed a new X-ray photoelectron spectroscopy (XPS) technique that makes it possible to study the lithium/oxygen chemistry occurring during battery operation as a function of applied voltage and controlled oxygen pressure. 

From drug delivery to catalysis to optoelectronics, the need for efficient fabrication pathways for particles over a wide range of sizes, from a variety of materials, and in many different structures is critical to functionality. Researchers in IRG-III have exploited the inherent scalability of fiber production and an in-fiber Plateau–Rayleigh capillary
