Liquid–liquid phase separation in bulk proceeds through the continuous coalescence of droplets until the system undergoes complete phase separation. But when colloids, nanoparticles or proteins are confined to interfaces, surfaces or membranes, their interactions differ fundamentally from those mediated by

With a particular focus on engaging and including Native Americans in its entire range of programs, GEMSEC is weaving a fabric of education offerings to seamlessly support and complement its research thrusts.

We are excited to announce that the Research Triangle MRSEC has won the Dean’s Award for Inclusive Excellence in Graduate Education!

A partnership between the NU-MRSEC and the Art Institute of Chicago provides fertile ground for curriculum development. Lisa Backus, a high school chemistry teacher and participant in the Center's 2006Â’  Research Experience for Teachers (RET) program was inspired by her summer research project working on conservation science problems of Ancient Chinese jades and Winslow Homer watercolors. The result is an art-based high school chemistry module that introduces students to the properties of light, the atom, and organic compound pigments.

On April 8, 2017, PCCM held its first Día de la Ciencia at the Princeton Public Library. Forty scientists, mostly PCCM members, at 20 tables, met with over 500 members of the community.

Semiconductors with narrow energy gaps have electronic properties, including a high mobility and strong spin-orbit coupling, that are advantageous for electronic device applications. The switching speed of a field-effect transistor and the sensitivity of a geometrical magnetoresistor are improved by a high carrier mobility. In addition to these traditional devices, we are studying devices that take advantage of quantum-mechanical or spin-orbit effects.

Surface plasmons - collective oscillations of free charges - on metal surfaces have resulted in demonstrations of enhanced optical transmission, collimation of light through a subwavelength aperture, negative permeability and refraction at visible wavelengths, and second-harmonic generation. The structures that display these plasmonic phenomena typically consist of ordered arrays of particles or holes with sizes of the order of 100 nm.
