• Fundamental Conductivity and Resistivity of Water
  The most accurate values to date were determined for conductivity of water from 0-100°C, permitting new determination of high-temperature hydroxide ion equivalent conductance. These values were incorporated into a fundamental water coefficient table including hydroxide and hydrogen ion mobilities...
• MICRO: Critical Materials
  correctly. In different gas matrices, varying amounts of broadening occur. Hence, each gas must be associated with a unique line measurement or calibration. Understanding that direct line-broadening determinations (e.g., from a strong line absorption) are linearly consistent with calibrations...
• Determining critical trace elements in high-purity phosphoric acid
  for other high-purity chemicals at this level include graphite furnace atomic absorption spectrophotometry (GFAAS) for the determination of Group 1 elements and inductively coupled plasma mass spectrometry (ICP-MS) for all others. A more recent study has reported the applicability of ICP-MS under...

• Physical properties of CdS/ITO thin films growth by CBD technique with substrate oscillating agitation
  of the absorption coefficient. For Eg determination, the absorption coefficient of the ITO substrate was also taken into account, such that only Eg values for CdS films are reported. III. EXPERIMENTAL. CdS thin films were chemically deposited on 1x1 cm2 ITO/glass substrates (RsITO=10± 2 W, 200 nm thickness, rITO...
