Program Highlights

Materials for High Speed Fiber Optoelectronics

MRSEC researchers have developed the materials necessary to embed GHz speed electronic photodetectors into micron diameter channels in optical fibers.

Nanomotors Mimic Bacterial Motion

An international team studying the motion of  both bacteria and similar-sized artificial  catalytic nanomotors has found that they transfer momentum to their surroundings in a  similar way, despite their very different  propulsion mechanisms.

A Strong Ferroelectric Ferromagnet

Ferroelectric ferromagnets are a holy grail of materials research, since they would enable electrically  switchable magnetism with diverse potential applications in information technology, sensing and new  “e

Folding sheets are a form of soliton

MRSEC scientists and collaborators have shown [1] that the localized buckling of a compressed thin sheet, important for molecular interfaces, [2] has the same mathematical origin

Sweeping out electrons with carbon nanotubes to achieve high efficiency solar cells

Luping Yu, Dmitri Talapin and collaborators from the University of Chicago MRSEC are working to develop highly efficient bulk heterojunction organic solar cells.  They have recently

Theoretical and Experimental Characterization of Structures of MnAu Nanoclusters

Highly-symmetrized MnAu nanoalloys may possess high magnetic moments for potential application. The magnetic properties of MnAu nanoclusters exhibit strong dependence on the cluster sizes and morphologies.

High-Sensitivity Detector for Molecular Sensing using Magnetic Particles

The detection of noxious gases or bio-agents is important for various environmental and security needs. High sensitivity, sufficient selectivity and molecular recognition are key characteristics for such sensing. Nebraska MRSEC researchers have developed a scheme for molecular sensing using magnetic tracer particles and a microcantilever torsional magnetometer.

Electric Field Control of Magnetization

To change the magnetization of a ferromagnet usually requires a magnetic field.  So, for example, if we put a compass needle into the high field of an MRI machine, we can no longer trust it to swivel to the North.  Similarly, the magnetic stripes on credit cards and key cards can be destroyed in high magnetic fields.  Electric fields don’t have the same effect on magnetic materials, which is ju

Organic Ferroelectric Photovoltaics

Photovoltaics is a method of converting solar radiation into electricity.  Some semiconducting materials exhibit a property known as the photoelectric effect that causes them to absorb light and release electrons. In addition to the semiconductors, ferroelectric materials have been employed to create ferroelectric-photovoltaic devices.

Nebraska MRSEC Professor/Student Pairs Program

The Nebraska MRSEC Professor/Student Pairs Program brings in professor/student pairs from non-research intensive four-year institutions to conduct research with Nebraska MRSEC scientists.  The goal is to provide a research experience which benefits both the participants and the MRSEC projects.  For the professor, this program provides an opportunity to conduct new research, access to facilities
