Carbon nanotubes twice as strong as once thought

Carbon nanotubes — those tiny particles poised to revolutionize electronics, medicine, and other areas — are much bigger in the strength department than anyone ever thought, scientists are reporting. New studies on the strength of these submic…

MIT researchers develop a way to funnel solar energy

CAMBRIDGE, Mass. – Using carbon nanotubes (hollow tubes of carbon atoms), MIT chemical engineers have found a way to concentrate solar energy 100 times more than a regular photovoltaic cell. Such nanotubes could form antennas that capture and focus …

Carbon mapping breakthrough

Palo Alto, CA — By integrating satellite mapping, airborne-laser technology, and ground-based plot surveys, scientists from the Carnegie Institution’s Department of Global Ecology, with colleagues from the World Wildlife Fund and in coordinatio…

Scientist sees evidence of 'onions' in space

Scientists may have peeled away another layer of mystery about materials floating in deep space. Tiny multilayered balls called “carbon onions,” produced in laboratory studies, appear to have the same light-absorption characteristics as dust particles in the regions between the stars. “It’s the strongest evidence yet that cosmic dust has a multilayered onionlike carbon structure,” said Manish Chhowalla, assistant professor of ceramic and materials engineering at Rutgers, The State University of New Jersey. Chhowalla used transmission electron microscopes to study radiation absorption of the laboratory-produced onions and found characteristics virtually identical to those reported by astrophysicists studying dust in deep space.

Researchers use buckyballs to reinvent 'antibiotic of last resort'

Chemists hope a new variant of vancomycin that contains buckyballs — tiny cage-shaped molecules of pure carbon — could become the world’s first targeted antibiotic, creating a new line of defense against bioweapons like anthrax. Vancomycin, which entered clinical service 40 years ago, is the antibiotic of last resort, given only when all others fail. Unfortunately, vancomycin-resistant strains of bacteria have appeared in recent years.

Gov't announces carbon capture and storage initiatives

Energy Secretary Spencer Abraham and Under Secretary of State for Global Affairs Paula Dobriansky will be joined by representatives from several invited countries to announce plans for an international forum to advance carbon and storage technologies. In addition, Secretary Abraham will announce a government-sponsored, public-private partnership to create the world’s first pollution-free, fossil fuel fired power plant. The announcements follow a briefing to the President by Secretary Abraham, Secretary of State Colin Powell and Environmental Protection Agency Administrator Christine Todd Whitman.
