Enhanced Exciton Diffusion using Phosphor Sensitization

Russell Holmes

Graduate student Wade Luhman has demonstrated a route to enhance the short exciton diffusion length (LD) of organic semiconductors by combining fluorescent and phosphorescent materials into a single electron donating thin film.

Mechanism of Molecular Exchange in Block Polymer Micelles

Frank Bates, Tim Lodge

Using small-angle neutron scattering, we investigated the mechanism of molecular exchange in spherical micelles formed by diblock copolymers in an organic solvent.

One-way photonic behavior

Zheng Wang, Yidong Chong, J.D. Joannopoulos & Marin Soljacic (MIT)

Research funded in part by the MIT MRSEC has led to a discovery of one-way photonic behavior. A team made up of MIT physicists Zheng Wang, research scientist in MIT's Research Laboratory of Electronics; recent MIT PhD recipient Yidong Chong; Professor John Joannopoulos; and Professor Marin Soljacic have developed and experimentally tested photonic crystals that restrict light to travel

Self-Repairable Polyurethane Networks

Polyurethanes have many properties that qualify them as high performance polymeric materials, but they still suffer from mechanical damage. We report the development of polyurethane networks that exhibit self-repairing characteristics upon exposure to ultraviolet light. The network consists of an oxetane-substituted chitosan precursor incorporated into a two-component polyurethane. Upon mechanical damage of the network, four-member oxetane rings open to create two reactive ends.
