Picoprojectors using Ferroelectric Liquid Crystal Microdisplays
Center researchers are collaborating with spin-off Displaytech to develop FLC materials for application in picoprojectors. The high quality time sequential color and high brightness enabled by FLC switching speed makes FLC-on-silicon an excellent display technology for picoprojectors, currently being marketed by 3M.

Liquid Crystals a Sensitive Probe of DNA Hybridization
Liquid crystals that realign in response to DNA can reveal subtle sequence alterations, even a single base mutation. Center investigator Dan Schwartz.and doctoral student Andrew Price showed that nematic liquid crystals, which naturally align themselves perpendicular to the surface of a surfactant-coated glass slide, tilt slightly following the addition of short lengths of single stranded DNA.

Quantum Dot Circuits
Cherie R. Kagan and Christopher B. Murray
Kagan and Murray fabricated the first electronic
circuits from nanometer scale semiconductor particles known as quantum dots.
These quantum dots are synthesized in solution and tailored in the shape of
cubes so when they are assembled into solids, they fill space. The nanoscale cubes allow for high
performance thin film electronics. The chemistry developed further allowed
these circuits to be realized on plastics for flexible electronic applications.

Soft Spots in Disordered Colloidal Packings
Andrea J. Liu and Arjun G. Yodh
Like
liquids, solids can flow under applied shear stresses. In crystalline solids, figuring out vulnerable regions where the material will break under stress is
well-established—they are typically controlled by a population of defects in
the crystal structure known as dislocations.
In disordered solids, however, defects are everywhere, making the task
of identifying such vulnerable spots
much more daunting.
