  • Understanding FTIR Peaks of PO4 Compounds • Physics Forums
    The discussion focuses on the interpretation of FTIR (Fourier Transform Infrared Spectroscopy) peaks for PO4 (phosphate) compounds It establishes that multiple peaks at different wavelengths arise from various vibrational modes of the molecule, including stretching and bending vibrations Specifically, the modes v1, v3, and v4 correspond to distinct types of molecular vibrations, such as
  • Why does a Walrus Blush? | Geophysical Institute
    The skin of walruses becomes pallid when it is exposed to cold air or water and changes to pink when exposed to warmer ambient temperatures This color change may indicate that the circulatory output to the skin is altered to control their total body heat loss
  • Pink salmon — too much of a good thing? | Geophysical Institute
    Pink salmon born in hatcheries, where professionals harvest eggs from wild salmon and rear them in captivity before releasing them in the ocean, have doubled in numbers since 1990 Russians have pink salmon hatcheries that increase numbers in the North Pacific and Bering Sea Alaskans run hatcheries in Valdez and other places in Prince William

  • UAF scientist designing satellite to hunt small space debris . . .
    A University of Alaska Fairbanks scientist is participating in a U S government effort to design a satellite and instruments capable of detecting space debris as small as 1 centimeter, less than one-half inch
  • Exploration into the Physics of Rainbows
    The simplest explanation of rainbow physics is based on internal reflections in the near-spherical shape of a raindrop
  • Aurora Forecast - Geophysical Institute
    The aurora is most often seen as a striking green, but it also occasionally shows off other colors, ranging from red to pink or blue to purple Oxygen at about 60 miles up gives off the familiar green-yellow color, while oxygen at higher altitudes (about 200 miles above Earth’s surface) gives all-red auroras
