Recent experiments have shown the absence of the thermoelectric effect in metallic carbon nanotubes. Building upon earlier theoretical work, researchers at the University of Illinois say they can explain this peculiar behavior, and put it to good use.
The U.S. Environmental Protection Agency (EPA) has acknowledged that its voluntary approach to reporting has yielded only limited information on a small fraction of the hundreds of potentially toxic nanomaterials already in commercial use or in development in the United States, according to Environmental Defense Fund (EDF).
Thousands of high school and middle school students begin a journey this month that they hope will take them to the finals of the U.S. Department of Energy?s (DOE) annual National Science Bowl, America?s largest and most prestigious science competition for middle and high school students.
SPIE, the international society for optics and photonics, and Laurin Publishing, publisher of Photonics Media, have announced the 67 finalist companies for the 2008 Prism Awards for Photonics Innovation, the premier competition for the photonics industry worldwide.
On January 12, 2009, the Environmental Protection Agency (EPA) in the U.S. released its interim report on the Nanoscale Materials Stewardship Program (NMSP). The document is available as a download from the EPA site.
IBM Research scientists, in collaboration with the Center for Probing the Nanoscale at Stanford University, have demonstrated magnetic resonance imaging (MRI) with volume resolution 100 million times finer than conventional MRI.
Recognizing that energy is at the heart of many of the world's tribulations - economic, environmental and political - Stanford is establishing a $100 million research institute to focus intently on energy issues, President John Hennessy announced today.
In experiments that pave the way for tiny mobile surgical tools activated by heat or chemicals, Johns Hopkins researchers have invented dust-particle-size devices that can be used to grab and remove living cells from hard-to-reach places without the need for electrical wires, tubes or batteries. Instead, the devices are actuated by thermal or biochemical signals.
Jeffrey Welser, Ph.D., director of the Semiconductor Research Corp.'s Nanoelectronics Research Initiative, made those comments following South Bend?s Jan. 5 announcement of a brand new name for an emerging 83-acre technology park ? Ignition ParkSM - which the city will market to nanoelectronic and other technology-based businesses.
