Program Highlights for year 2009

One-way photonic behavior

Research

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

Self-Repairable Polyurethane Networks

Research

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.

Synthesis, Assembly and Fabrication of Molecular Materials for Technology and Medicine Using Genetically Engineered Solid-Binding Peptides

Research
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;

Flexible fiber cameras

Research

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,

Electronic phase transition in graphene in a magnetic field

Research

Graphene is comprised of a single layer of C atoms in a hexagonal lattice array.  The electronic state of graphene is of great interest because the electron energy increases linearly with momentum, just like for photons and neutrinos.  This is called a massless, Dirac dispersion.  The nature of the electronic state at zero energy (the “Dirac point”) in a strong magnetic field H is curr
