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.

Synthesis, Assembly and Fabrication of Molecular Materials for Technology and Medicine Using Genetically Engineered Solid-Binding Peptides
The “life” in organisms is due to the specific molecular interactions of proteins, called molecular recognition, that leads to a self-assembly and a large diversity of functions in biology;
Emulating biology, in Molecular Biomimetics, GEMSEC is developing novel protocols towards materials and systems based on proteins, engineered in our labs;

A team of researchers, led by Yoel Fink of the MIT MRSEC, has developed
light-detecting fibers that can be woven together to create a flexible,
basic camera. These fibers are each less than a millimeter in diameter,
and consist of several nested layers of light-detection materials. The
fibers measure the intensity of the light illuminating them and convert
it to an electrical signal, which is then fed into a computer that
