Iodine Stabilized Laser Strainmeter [PDF]
Geophysical Journal International, 1974 Summary A new type of laser strainmeter has been operated in Queensbury tunnel, Yorkshire, England. It has design features which possess fundamental and practical advantages over other laser strainmeters which have been constructed. The system uses two helium-neon lasers which operate at 633 nm. One illuminates a Michelson interferometer with a 54 m

Active laser frequency stabilization using neutral praseodymium (Pr)
, 2009 We present a new possibility for the active frequency stabilization of a laser using transitions in neutral praseodymium. Because of its five outer electrons, this element shows a high density of energy levels leading to an extremely line-rich excitation

Structural biology of ferritin nanocages
FEBS Letters, EarlyView.Ferritin is a conserved iron‐storage protein that sequesters iron as a ferric mineral core within a nanocage, protecting cells from oxidative damage and maintaining iron homeostasis. This review discusses ferritin biology, structure, and function, and highlights recent cryo‐EM studies revealing mechanisms of ferritinophagy, cellular iron uptake, and ...
