Nanotubes (nanohair) grown on carbon fiber (Man's forehead). The scanning electron microscope (SEM) image (15.0kV, 10.0k, WD: 8.0mm) was obtained using a Hitachi S-4800 HR-SEM at NEST, University of Dayton.

Fingerprints of High-Temperature Attack of Sodium Vapor onto Quartz Surface

Filed under the keywords

Sudden boiling of liquid sodium (b.p. = 1156 K at 1 atm) inside the all quartz-made smelting/evaporation chamber results in condensation and high-temperature reaction of sodium vapor with the inner wall surface. The attack and reaction becomes more aggressive with increasing vapor temperature. The condensation "fingerprints" express different color bands from silver, metallic, milky, brown, orange, red, and black with increasing level of the sodium attack and reaction on the surface.
