Video of the week – Nanotube speakers

By / November 19, 2008

We posted about this novel use of carbon nanotubes as audio speakers on Monday, but today we have a video of the real deal, courtesy of the American Chemical Society. The first part of the video shows the transparency of such a speaker. The second part is an illustration of the way the CNTs create…

Group thinks its ‘black silicon’ boosts photoconductive gain

By / November 3, 2008

Why settle for one photon when you can get 200-300? That’s the idea behind a new material being developed by SiOnyx, a new Massachusetts company. The company using a method to reshape the surface of silicon to create cones that it says makes the material effectively function as “sponge for light.” is making a new type of silicon…

Thin film sandwich feeds hunger for superconductors

By / November 1, 2008

Though looking sort of glum at the time, Ivan Bozovic is successfully leading Brookhaven Labs’ thin-film superconductor project. Researchers at DOE’s Brookhaven National Lab have developed a sandwich of thin films that, at the point where the films touch, offers a nanometer-sized area of superconductivity. Moreover, as reported in the Oct. 9 edition of Nature magazine, the superconductivity…

Chinese academy reports ZnO nanorod FET breakthrough

By / October 25, 2008

The Chinese Academy of Science reports that scientists at its Institute of Microelectronics have successfully formed a zinc oxide nanorod field-effect transistor, the “first of its kind as a nano device.” The ZnO nano materials, such as nanowires, nanorods, nanobands and nanorings, attract intense worldwide attention for their unique optical, semiconducting and piezoelectric properties. At…
