MIT researchers have developed a new way to tune the frequency of lasers that operate in the terahertz spectrum. The result is an important step toward airport scanners that could tell whether a vial in a closed suitcase contains aspirin, methamphetamines or an explosive.
Very often in science, the unexpected discovery turns out to be the most significant. Rice University Professor Junichiro Kono and his team weren't looking for a breakthrough in the transmission of terahertz signals, but there it was: a plasmonic material that would, with adjustments to its temperature and/or magnetic field, either stop a terahertz beam cold or let it pass completely.
When are we sufficiently protected from danger? Does the state ensure that risks are kept to a minimum? The question about how far state risk prevention can go and the degree of safety that state measures can, may and must offer is raised not only in the field of consumer health protection.
A massive, data-crunching computer search program that matches fragments of potential drug molecules to the known shapes of viral surface proteins has identified several FDA-approved drugs that could be the basis for new medicines.
Welchen Beitrag koennen Mikro- und Nanotechnologien leisten, um die Leistung von Automobilen zu steigern und Verbrauch und Schadstoffausstoss zu verringern? Mit dieser Frage beschaeftigt sich die Veranstaltung 'Oberflaechenbearbeitung mit Mikro- und Nanotechnologien fuer den Automotivbereich' am 16. Dezember 2009 in Dortmund.
Tiny devices made possible by combining the latest advances in mechanical and electronics technology could be at the heart of next-generation navigation and vehicle stabilisation tools thanks to European researchers.
Extremely thin, flexible high-efficiency silicon solar cells are the solar cells of the future, according to Professor Miro Zeman. This is the gist of the inaugural address he will be giving to mark his appointment as Professor of Photovoltaic Materials and Devices at TU Delft.
The Chinese Academy of Sciences and Inspur Group have started a joint project to develop the third-generation genome sequencing instrument, which might slash the cost of genome sequencing by 99 percent.
Semiconductor Research Corporation, the world's leading university-research consortium for semiconductors and related technologies, and researchers from Stanford University and Taiwan Semiconductor Manufacturing Company have announced they have developed the industry's first top-gated field effect transistor (FETs) and CMOS inverters featuring 20 nanometer contact holes using diblock copolymer lithography.
University of Nevada, Reno Professor Kam Leang, who himself has not missed his monthly ski date for the last seven years, and has been buildng his own skis in his garage for several years, wants to inspire his mechanical engineering students to get interested in real world nanotechnology.
