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.

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,
Graduate students at the University of Arkansas bring cutting edge technology to local middle school students and allow them to explore the world of nanoscience in real-time.
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
In an ordinary insulator, such as diamond, the occupied electronic states are separated from unoccupied states by a large energy “gap”. The gap prevents current flow when an electric field is applied. Recent research has uncovered a new class of insulators, called topological insulators, in which electrons can bypass the energy gap by moving in surface states. The energy vs.
Professor Belcher previously engineered viruses that could build an anode by coating themselves with cobalt oxide and gold and self-assembling to form a nanowire.
