Device Simplifies Measurement of Fluoride Contamination in Water

  • Magazine Article
  • TBMG-35149
Published 2019-09-01 by Tech Briefs Media Group in United States

Adding fluoride to water has been common practice in a number of countries including the U.S. In low concentrations (below 1.5 mg/L), fluoride can help prevent tooth decay and strengthen bones; however, at higher levels, it can have the opposite effect, causing serious dental and bone disease, especially in children and developing fetuses. To determine whether drinking water is safe, fluoride must be detected in water at a parts-per-million (ppm) level. Measuring fluoride at such low concentrations with sufficient accuracy is expensive and requires a well-equipped chemical lab.

Crystal-Free Formation of Non-Oxide Optical Fiber

  • Magazine Article
  • TBMG-32478
Published 2018-08-01 by Tech Briefs Media Group in United States

Researchers at NASA's Marshall Space Flight Center have devised a method for the creation of crystal-free non-oxide optical fiber preforms. Non-oxide fiber optics are extensively used in infrared transmitting applications such as communication systems, chemical sensors, and laser fiber guides for cutting, welding, and medical surgery. Some of these glasses, however, are very susceptible to crystallization. Even small crystals can lead to light scatter and a high attenuation coefficient, limiting their usefulness. NASA has developed a new method of nonoxide fiber formation that uses axial magnetic fields to suppress crystallization. The resulting non-oxide fibers are crystal-free and have lower signal attenuation rates than silica-based optical fibers.
