ATLANTA, Aug. 29, 2007 -- A new class of metal oxide-based tubular nanomaterials that can be produced in water also offer a high degree of control over their diameter and length, unlike carbon nanotubes. The new single-walled inorganic nanotubes are being developed for a range of nanotechnology applications that require such precise control. At the Georgia Institute of Technology, researchers are studying the formation of these metal oxide nanotubes, produced in combination with silicon and germanium, to understand the key factors that drive the emergence of nanotubes with specific diameters and lengths from a...Read full article

    Glossary
    germanium
    A crystalline semiconductor material that transmits in the infrared.
    nano
    An SI prefix meaning one billionth (10-9). Nano can also be used to indicate the study of atoms, molecules and other structures and particles on the nanometer scale. Nano-optics (also referred to as nanophotonics), for example, is the study of how light and light-matter interactions behave on the nanometer scale. See nanophotonics.
    nanometer
    A unit of length in the metric system equal to 10-9 meters. It formerly was called a millimicron.
    photonics
    The technology of generating and harnessing light and other forms of radiant energy whose quantum unit is the photon. The science includes light emission, transmission, deflection, amplification and detection by optical components and instruments, lasers and other light sources, fiber optics, electro-optical instrumentation, related hardware and electronics, and sophisticated systems. The range of applications of photonics extends from energy generation to detection to communications and...
