  • History of Carbon Nanotubes -CNTs
    . Carbon Nanotubes (CNTs) may consist of one tube of graphite, a one-atom thick single walled nanotubes (SWNTs) a two atom thick double walled carbon nanotubes (DWNTs) or a number of concentric tubes called multiwalled nanotubes (MWNTs). When viewed with a transmission electron microscope these tubes
  • Titanium & Zirconium Rammed Graphite Castings for Industrial Applications (.pdf)
    This paper describes the production of rammed graphite titanium and zirconium castings. This process is similar to the sand casting process used to cast many common iron base alloys. Issues such as mold preparation, melting, processing, properties, markets and applications are addressed. You may
  • TruMac CN: Carbon/Nitrogen in Coal, Coke, Carbon, Black & Graphite
    Samples must be of uniform consistency to produce. suitable results, preferably minus 60 mesh. Carbon and. nitrogen results for coal, coke and select reference. materials are typically reported on a dry basis. Therefore,. either the materials must be dried prior to analysis or the. moisture content
  • Low Speed Carbon Deposition Process for Hermetic Optical Fibers (.pdf)
    fiber during the draw process by. pulling furnace; indeed, on most high-. means of chemical vapor deposition. speed towers, cooling tubes are. For carbon coatings specifically, a hydro-. employed to reduce the fiber tempera-. carbon precursor gas is introduced to the. ture before the liquid coating
  • The Advantages of Tantalum and Nickel-Based Alloy Shell and Tube Heat Exchangers vs. Carbon Block Heat Exchangers in Active Pharmaceutical Intermediate Applications. Author: Lawrence J. Haubner - ©2014
    Abstract: The pharmaceutical industry has traditionally used resin-impregnated graphite block heat exchangers for handling corrosive fluids in their active pharmaceutical ingredient (API) manufacturing facilities. Tantalum and high nickel alloy shell and tube condensers have emerged as a versatile
  • High Temperature and High Resolution Observation EELS Analysis (HF-2200 TEM 114)
    of these tubes a high level of technical expertise was needed. There are two types of carbon nano-tubes; MWNT or multi-walled nano-tube and SWNT or single walled nano-tube. MWNT is composed of 2 to 30 layers of graphite sheets.
  • History Of CNTs
    In 1980 we knew of only three forms of carbon, namely diamond, graphite, and amorphous carbon. Today we know there is a whole family of other forms of carbon. The first to be discovered was the hollow, cage-like buckminsterfullerene molecule - also known as the buckyball, or the C60 fullerene
  • Ball Milling
    Ball milling and subsequent annealing is a simple method for the production of CNTs. It is well-established that mechanical attrition of this type can lead to fully nanoporous microstructures, it was not until a few years ago that CNTs of carbon and boron nitride were produced from these powders
