2003–04 ORGANIC GRADUATE FELLOWSHIPS
The ACS Division of Organic Chemistry has announced its annual fellowship awards to outstanding third- and fourth-year graduate students in organic chemistry. Awardees are selected on the basis of their research accomplishments and a short original essay. The essays are on the Web at http://www.organicdivision.org/fellowships_previous.html.
The fellowship stipend this year is $20,000, and the fellows will travel to the 2005 National Organic Symposium, June 12–16, 2005, University of Utah, Salt Lake City, to present a poster on their work. Each fellowship is sponsored by a prominent company or organization. This year, the division is presenting the first endowed fellowship--the Emmanuil Troyansky Fellowship, awarded every other year.

Griffith Honored For Eyeglass Process
Griffith's invention encompasses not only a cheap and efficient eyeglass-manufacturing setup, but also a more efficient method for diagnosing eyeglass prescriptions. Since automated prescription diagnosis is typically error-prone and needs supervision--increasing costs significantly--Griffith came up with a prototype device that looks like an oversized pair of goggles. After the goggles are put on, an electronic sensor monitors the lenses in the patient's eye and adjusts the goggle's lenses to cancel refractive errors, better determining the patient's prescription.
The manufacturing device uses a process known as programmable molding. In the machine--a portable apparatus similar to a desktop printer--Griffith can produce most prescription lenses in five to 10 minutes. The device works by casting lenses on a programmable membrane through a combination of pressure and constraints. The membrane then becomes the lenses' mold surface. Most typical eyeglass lenses can be cast from two such mold surfaces, alleviating the need for a large library of expensive molds. The result is a process that generates less waste and can be used efficiently even in less populated areas.
The Lemelson-MIT Student Prize is awarded annually to an MIT senior or graduate student who has demonstrated remarkable inventiveness.
