  • Crane handles lifting of heavy metal
    Excelsior Steel installed an automated overhead handling system to improve inventory tracking and provide product protection.
  • Evaluation of Two Organoclays, Clinoptilolite and Hydroxy-Apatite as Sorbents for Heavy Metal Removal from Water
    A series of column tests where performed with four sorbent media to determine their effectiveness for the removal of heavy metals from water. The sorbents are an organoclay, an organoclay/anthracite blend, clinoptilolite (a zeolite), and hydroxy-apatite. Heavy metals studied were Ni, Cr, Cu, Cd
  • Getting Plant Genes To Glow: New technique emerges from metal absorption studies
    Plant, Soil, and Nutrition Laboratory at Cornell University, in Ithaca, New York. It may eventually help plant studies of all kinds. "This enables us to quickly determine in which cells of a plant's root or shoot particular genes, regulating everything from micronutrient nutrition to heavy-metal
  • Metal Chain Drives
    chain drives do not slip, they cannot provide the overload and jam protection of belt drives. Also, the heavy weight of metal chain compared with light rubber belts produces penalties in efficiency, cost, and response time. Efficiency for chain drives -- about 85 to 90% -- is slightly less than
  • Heavy Piercing with Plasma
    High-density plasma arc cutting can effectively cut thick plate. The most challenging aspect, in fact, is that initial pierce. To that end, a few basic strategies help overcome this challenge, allowing the plasma to pierce through inches of metal as effectively as possible.
  • Powder Metal Designs Win PowderMet 2009 Awards
    and appliances, hand tool and recreation, and aerospace and military categories. The automotive-engine grand prize went to a powdered-metal (PM) steel manifold developed by , Carson, Calif., and Capstan's customer , Bloomfield, Conn. The manifold, assembled with a solenoid into the valve-train of a heavy
  • Using a buffered rinse solution to minimize metal contamination after wafer cleaning
    rapidly and thoroughly. The detrimental effects on IC devices of metallic contaminants from cleaning chemistries and other sources have been studied extensively. Heavy metals in silicon can form efficient charge generation or recombination centers, increasing the leakage current of junctions. Sodium
  • Tungsten
    Tungsten is a heavy metal that can be classified as a refractory metal, i.e., one with a high melting point. Refractory metals can be useful for their strength at high temperatures and their resistance to corrosion. Tungsten is difficult to melt, so commercial non-alloyed tungsten is produced

  • Environmental Impacts of Metallic Elements
    The book is a thorough study of mining activities, extraction procedures, heavy metal pollution, detection, treatments and remediation methods in ex-mining areas.
  • Plant-Based Remediation Processes
    At present, there are about 420 species belonging to about 45 plant families which have been reported as hyperaccumulators of heavy metals (Cobbett 2003).
  • Advances in Environmental Technologies
    Occurrence, Distribution, and Assessment of Heavy Metals in Roadside Dusts in Universities in Beijing, China .
  • Bio-Geo Interactions in Metal-Contaminated Soils
    Since metal contamination is an increasing ecological and ecotoxicological risk, the basic understanding of processes involved in metal mobilization as well as sorption and mineralization are the key features for remediation actions in the field of heavy metal -contaminated land management.
  • The Plant Family Brassicaceae
    Considerable amounts of heavy metals can be retained in the cell walls, especially of ecto- and ericoid mycorrhizal fungi, thus limiting metal uptake by the plants.
