  • Arc Method of CNT Synthesis
    the CNTs from the soot and the residual catalytic metals present in the crude product. This method creates CNTs through arc-vaporization of two carbon rods placed end to end, separated by approximately 1mm, in an enclosure that is usually filled with inert gas (helium, argon) at low pressure (between 50
  • MICRO:February 1998:Product Technology News
    absorption and possible contamination of downstream processes. All wetted surfaces are made of PFA, and carbon rods encapsulated in the material ensure dimensional stability for precise automated handling. The carrier is available in 26- or 52-wafer capacities. The 52-capacity carrier weighs 1.54 kg
  • Weighing Single Atoms?
    Recent research in nanoelectromechanical systems (NEMS) has focused on tiny RF oscillators built from silicon rods. But replacing the silicon rod with a carbon nanotube let Cornell University researchers shrink the oscillators even further and make them more durable and sensitive to mass changes
  • Metal-Film Resistors
    Metal-film resistors are produced by depositing a resistive element on a high-grade, ceramic rod. The metal film's resistive element may be carbon, nickel chromium; or a mixture of metal and glass, or metal and metal oxide. The precise resistance is achieved by removing part of the metal film
  • A new buckyball bounces into town
    graphite rods, turning them to soot. Nanomaterials are extracted from this soot. Buckminster fullerenes such as C are hollow molecules made of interlocking pentagons and hexagons of carbon atoms. They were discovered in 1985 after being produced in a lab and got their name for their resemblance to R
  • Laser Machining Fiber-Reinforced Plastics
    Fibre-reinforced plastic (FRP) is a composite structural material containing high-strength fibrous embedded reinforcements which develop mechanical properties greatly superior to the base polymer (called 'matrix' in this context). The fibers are usually fiberglass, carbon, or aramid (a family
  • Superstrong nuts and bolts
    reinforced with long-carbon fibers, Icotec's lightweight nuts and bolts sport ultrahigh specific strengths of up to 2.4 million psi/lb/in.3 This contrasts to aluminum and titanium with specific strengths of about 0.2 million and 1.2 million psi/lb/ in.3, respectively. The composite's semicrystalline
  • Laser Methods of CNT Synthesis
    by heat treatment in a vacuum at 1000oC to remove the C60 and other fullerenes. The initial laser vaporization pulse was followed by a second pulse, to vaporize the target more uniformly. The use of two successive laser pulses minimizes the amount of carbon deposited as soot. The second laser pulse
