Stabilized emulsions containing the oscillating Belousov - Zhabotinsky chemical reaction (BZ) show interesting dynamics. Each drop acts as an independent chemical clock. However, they chemically communicate and exhibit collective behavior. In (a) six BZ drops are contained in a  capillary tube. The  white bars are light, which set the oscillators in the reduced state. Drops 1 & 6 are always exposed to light, setting the boundary conditions. Drops 3 & 4 are

  A simple computational model demonstrates the assembly of self-limited filamentous bundles. The images are taken from dynamic Monte Carlo simulations in which "chiral" subunits ( with a preference to form twisted arrays of one "handedness") spontaneously assemble under different interaction strengths and degrees of chirality.  

Background: Most organic devices, from organic light emitting diodes to organic spintronic devices vertical devices, where the essential interfaces are buried and thus not subject to investigation. 

Following up on their recent creation of light-sensitive fibers, Professors Yoel Fink and Joannopoulos and their research teams have developed fibers that can detect ("hear") and produce sound ("sing").

Since its development in China thousands of years ago, silk from silkworms, spiders and other insects has been used for high-end, luxury fabrics as well as for parachutes and medical sutures. Now, MRSEC supported researchers are untangling some of its most closely guarded secrets, and explaining why silk is so strong, a question that has remained unresolved. Buehler and co-workers of the MIT MRSEC IRG-II have

Our team has developed a simple solution-based method to fabricate arrays of ZnO nanowires inside of a glass microchannel. 

Graduate student Mingjing Ha working with Optomec, Inc. and Northwestern University collaborators (Mark Hersam) has demonstrated low voltage, fast carbon nanotube (CNT) circuits printed on flexible plastic substrates. The circuits are fabricated by aerosol jet printing from a liquid dielectric ink (ion gel) and a purified semiconducting CNT ink (Northwestern). The printed semiconducting CNTs form the channels in thin film transistors and printed circuits.

We have demonstrated the first ever hybrid polymer film of an insoluble polymer with an acid (top picture).
