  • Low Speed Carbon Deposition Process for Hermetic Optical Fibers (.pdf)
    For optical fibers used in adverse environments, a carbon coating is frequently deposited on the fiber surface to prevent water and hydrogen ingression that lead respectively to strength degradation through fatigue and hydrogen-induced attenuation. The deposition of a hermetic carbon coating onto
  • Chemical Vapor Deposition
    Chemical vapor deposition (CVD) of hydrocarbons over a metal catalyst is a classical method that has been used to produce various carbon materials such as carbon fibers, filaments, etc. for over twenty years. Large amounts of CNTs can be formed by catalytic CVD of acetylene over Co and Fe catalysts
  • History of Carbon Nanotubes -CNTs
    this was not a practical method for making large quantities. Carbon Nanotubes (CNTs) have probably been around for a lot longer than was first realized, and may have been made during various carbon combustion and vapor deposition processes, but electron microscopy at that time was not advanced enough
    unplanned shutdowns for cleaning. Furthermore, dissolution of calcium carbonate leads to uncontrolled formation of carbon dioxide (gas) in the process, which causes problems such as foaming etc. This paper will demonstrate that using a carbon dioxide based solution from Linde, to prevent dissolution
  • Reaction of Steam and Methane Over Novel YSZ -LaB6 Composites and Nickel-YSZ Cermets (.pdf)
    Current SOFC Ni-YSZ cermet anodes suffer from a number of problems when exposed to methane-containing fuels at typical operating temperatures. These include; carbon deposition, nickel sintering and poisoning by sulfur present in the methane supply; ultimately these processes result in degradation
  • Electron Radiation as an Indicator of Gold Nodule Defect during E-beam Evaporation
    and deposited the Au film at 5 A/sec. Deposition. rate is controlled by an Inficon XTC-2 crystal monitor,. which adjusts the beam power using signal feedback from. the crystal to maintain the deposition rate. This is a typical. Fiigure 3 EDX survey confirmed black specks are carbon. deposition control
  • Cathode Catalyst Degradation in PEM Fuel Cells - a Differential Electrochemical Mass Spectrometry Study (.pdf)
    Cathode electrocatalyst durability (nanoparticle Pt on carbon black support) is one of the key barriers for PEMFC commercialization. 48x36 Poster Template Cathode catalyst degradation in PEM fuel cells –. a differential electrochemical mass spectrometry study. Wei Li, Alan Lane. Dept
  • Medical Device Link .
    converted PECVD and diamond deposition tools to perform nanotube growth for profit; but these tools have limited capabilities at low temperatures, according to Jensen. "We believe that this is the first commercially available tool that is capable of high-precision aligned carbon nanotube growth
