  • Semiconductor: Conductivity and pH In HF Etch Solutions
    Hydrofluoric acid (HF) is used in semiconductor processing, glass etching and other industrial processes. The extremely corrosive and toxic nature of HF makes it difficult to handle, requiring special materials of construction. This is also true of the sensors needed for its measurement. The strong
  • Study Crowns HF the Item-Level King
    , says Odin president and CEO Patrick J. Sweeney II. HF won five of the eight tests that were conducted, while UHF fared better in two and one was a draw, he says. The most important category tested may be material dependence, since manufacturers must guarantee high read rates for RFID

  • Identifying the Right RFID: Why Knowing the Difference Between HF and UHF is Important For Your Industrial Application
    KNOWING THE DIFFERENCE. BETWEEN HF AND UHF IS IMPORTANT. FOR YOUR INDUSTRIAL APPLICATIONS. P. APER. A WHITE. Published 1/30/2013. ndustrial manufacturing is constantly adapting to pacity between the various RFID frequencies in order to. meet the ever-increasing productivity and efficiency ensure
  • The Effects of Frequency in HF Welding (.pdf)
    . · The Size of the Heat Affected Zone (HAZ). · The level of Magnetic Flux in the Impeder. More importantly, the theory identifies the "optimum" welding frequency for a particular. tube size, mill speed, and material. This paper includes a minimum of mathematics with the aim of making it straight. forward
  • Pedigree Tags Need HF; FDA Agrees
    a greater ability to penetrate obscuring materials and are less affected by the presence of liquids and moisture. This is simply because the radio waves are longer and small fluctuations result in less distortion. Admittedly, no RF system is immune to the effects of liquids and metals. Each frequency
  • High Resolution Electron Microscopy of Carbon Nano-Tube at Room and High 8. Temperatures (HF-2200 TEM 112)
    Carbon nano-tubes were discovered in 1991. These tubes are in the form of a filament and different from normal materials in size and structure. They were assumed to have unique characteristics. Extensive research on this material has been made in various fields, specifically in terms of material
  • High Temperature In-Situ Microscopy and EELS Spectroscopy of a Metal Precipitate (HF-2000 TEM 109)
    The high temperature in-situ microscopy technique, which allows continuous observation of changes of fine structures during heating process inside the specimen chamber of a microscope, has been found useful for revealing a mechanism for changes of inner structures in R&D of advanced materials
