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. Researchers in the Center for the Science and Engineering of Materials (CSEM) at the California Institute of Technology are changing that idea.

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. Marni earned bachelor's degrees in both Psychology and Materials Science from the University of Pennsylvania and a PhD in Materials Science from the University of California Berkeley.

Plasmon Propagation along Metallic Nanostructures
Marleen van der Veen, Jason Merrill, Mark Reed, Eric Dufresne
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
Yale: Jim Reiner, Fred Walker, T.P. Ma, Agham Posadas, Miamiao Wang, Charles Ahn AMD: Zoran Krivokapic; Spansion: Max Sidorov
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. To replace silicon dioxide, these new oxides must perform better by having a large dielectric constant and a small leakage current. The oxide LaAlO3 has a dielectric constant that is six times larger than that of 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. The power transfer scheme proposed, dubbed "WiTricity," could be used for wireless charging of autonomous electronic devices (e.g. laptops, cell-phones, iPods).

A New Generation of Spintronic Devices: MgO Magnetic Tunneling Junctions
We developed a low-pressure magnetron sputtering technique together with the linear dynamic deposition method and successfully fabricated a new type of magnetic tunneling junctions (MTJs) with (001) textured MgO barrier. We are the only US university to have achieved this success as of April 2007.
