Composite materials such as fiberglass, which take on a mix of properties of their constituent compounds, have been around for decades. Now, an MIT materials scientist is taking composites to the nanoscale, where entirely new properties, not found in any of the original compounds, can emerge.Michael Demkowicz, an assistant professor in MIT's Department of Materials Science and Engineering, is part of a team based at Los Alamos National Laboratory that recently received a federal Energy...

A scarcity of medical isotopes has forced physicians at scores of U.S. and Canadian hospitals to begin curbing the number of a variety of standard diagnostic tests they prescribe.  Hospital officials say they see no quick-fix in the immediate future. In May, Canadian health officials were forced to close down a nuclear reactor in eastern Ontario that provides roughly a third of the world's supply of medical isotopes that are used in a variety of now commonplace medical screenings to...

The shut down of a Canadian nuclear reactor has forced makers of medical isotopes, used for diagnostic imaging, to search for new suppliers.  The 50-year-old reactor, owned by Atomic Energy of Canada Ltd, was shut down by Canadian health officials after a small leak was found. The reactor, which produces nearly a third of the world's medical isotopes, is expected to be out of operation for many months. Currently, only five nuclear reactors produce molybdenum-99 or Mo-99, which is a...

Nation's Nuclear Plants Stronger, Safer Than Ever Before. JACKSON, Miss., March 23 /PRNewswire/ -- Thirty years ago, the United States experienced the worst nuclear plant accident in American history. Since that time, increased vigilance in safety has made the nation's 104 nuclear plants - including the 12 reactors operated by Entergy Nuclear - an even stronger and safer form of energy generation. "What happened 30 years ago at Three Mile Island served as a call to action for everyone in...

Engineers at the Ben-Gurion University of the Negev in Israel say they have developed a way to declaw nuclear fuel, ensuring only peaceful plutonium use. The engineers said their technique denatures plutonium created in large nuclear reactors, making it unsuitable for use in nuclear arms. They said that by adding Americium, a form of the basic synthetic element found in commercial smoke detectors and industrial gauges, plutonium can only be used for peaceful purposes. Professor Yigal Ronen,...

Physicists at The University of Texas at Austin have designed a new system that, when fully developed, would use fusion to eliminate most of the transuranic waste produced by nuclear power plants. The invention could help combat global warming by making nuclear power cleaner and thus a more viable replacement of carbon-heavy energy sources, such as coal. "We have created a way to use fusion to relatively inexpensively destroy the waste from nuclear fission," says Mike Kotschenreuther, senior...
