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.

“Artificial spin ice” is a term used for arrays of nanoscale magnetic islands on lattices that geometrically frustrate inter-island interactions.
Inks of inorganic nanocrystals hold great promise for printed electronics but the widely used organic surfactants (ligands) needed to stabilize these inks degrade the electrical quality of the printed films.
The idealized picture of an interface between two elemental materials is simply an abrupt transition between planes containing two different types of atoms.
The shape-dependent optical properties of metal nanostructures have motivated efforts to correlate nanoparticle structure with plasmonic behavior. In particular, gold bipyramids (BPs) are of interest due to their sharp tips that lead to strong localized field enhancement and high sensitivity to the surrounding environment.
Northwestern MRSEC provides the physical and intellectual infrastructure to nucleate collaborative opportunities in materials research both on and off the Northwestern campus, and continues to leverage its diverse portfolio of research into new educational and commercial opportunities. Recent examples include:
Teaching the Teachers
Electromagnetism at the Physical Sciences Inquiry Academy
These fifth-grade teachers are building electromagnetic ping pong ball launchers to demonstrate electromagnetism to their students.
Utah MRSEC leads lessons and activities for teachers, as well as provides educational kits which supplement curriculum andcoordinate with Utah Core Standards.
What’s the Problem? Macrophages are part of the innate immune system and will try to eat anything they don’t recognize as being part of the body — they’re like border patrol guards, checking everybody’s passports. If you’re a red blood cell, you have the right passport and get waved on.
The electronic properties of thin films with thicknesses of only a single molecular layer have in the past typically been far worse than thicker films of the same material.
