Program Highlights for year 2015

Dynamic Self-Pattering of Archimedes Spirals

A thin liquid crystal film on a surface of photoactive dye turns into a wonderland of exotic moving patterns if just illuminated by a simple lamp.  Spirals move and os

Quantum Dot / DNA Necklaces

 Researchers at the Soft Materials Research Center of the University of Colorado have made hybrid bio-semiconductor nano-necklaces consisting of strings of nanometer size quantum dots (QDs) tethered by nano-length DNA chains.  

Semiconductor Double Quantum Dot Maser

A conventional laser consists of three main components: a gain medium, a cavity, and an energy source. Researchers at Princeton and the University of Maryland Joint Quantum Institute have demonstrated a nanoscale laser that is driven by a single electron tunneling events.

The chiral anomaly in a Dirac semimetal

The notion of handedness or chirality (Greek for “hand”) is ubiquitous in chemistry, biology and physics. In quantum field theory, all massless particles (e.g. neutrinos) are chiral. The left- and right-handed populations are independent and never mix (Fig. A). However, inter-conversion occurs once electromagnetic fields are turned on.

Teachers as Scholars - Materials Science Program

On November 10 and 17, 2015, 18 teachers visited the Princeton Center for Complex Materials as part of Teacher Prep's program to learn about materials science and how to apply it to the classroom. This unique PCCM program is part of a larger "Teachers as Scholars" initiative as part of Princeton University's Teacher Preparation program.

American Indian Visit Day

In 2015, the University of Minnesota MRSEC expanded its American Indian Outreach activities with the inaugural American Indian Visit Day.

Liquid Crystal Nano-Flowers

The nanoscale structures of liquid crystals are rarely more exotic than that of the sponge phases of bent-core molecules, visualized here in an electron microscope image made by researchers at the Liquid Crystal Materials
