Program Highlights for year 2007

Design of tunable ferroelectric photonic structures

The IRG on ferroelectric nanophotonic materials and devices seeks to develop tunable photonic devices by combining the nonlinear dispersion of photonic metamaterials with the unusual optical properties of ferroelectric perovskites. A series of experimental tests and theoretical calculations have demonstrated the potential of this approach.

Woe to the Makers of Literal Translation

When proteins are made inside cells, genetic information (in the form of messenger RNA) must be "translated" into specific sequences of amino acid building blocks. Accurate translation is essential to the health of the cell, and the idea that "one gene gives one protein" emerged very early in the development of the field of molecular biology.

In Memorium of Marni Goldman

Marni Goldman, Education Director of CPIMA, died of natural causes in late February while on vacation with her family. Although she never walked and had only the most limited use of her arms, Marni's academic and professional accomplishments placed her in elite company, even as her friendships extended far and wide.

Plasmon Propagation along Metallic Nanostructures

Â’ Nanoscale metallic structures are promising platforms for sensors: using photons to launch surface plasmon "polaritons", metallic nanowires can guide and re-emit light over tens of microns. The re-emission of light at the other end of a nanowire can be promoted or altered by adsorption of molecules.

Crystalline oxides on silicon

Researchers at Yale University have invented a high-performance material for future generations of transistors and devices. New oxide materials are required to make faster computer chips for the future. These new oxides will replace the oxide that has been the standard for the last 50 years, silicon dioxide.

Power transfer goes cordless

Members of IRG-I of the MIT MRSEC have recently demonstrated wireless transfers of power on the order of 60W over distances greater than 7 feet, with efficiency of roughly 50%, confirming the predictions of an earlier theoretical paper.
