The effect of initially increased [N] just after oxygen admixture, which was predicted in Figure 5, is therefore verified and explained by reaction of vibrationally excited [N.sub.2] (X,v) with atomic oxygen
in the upper atmosphere is created when ultraviolet radiation from the sun breaks apart oxygen molecule (O2).
A shower of atomic oxygen
, on the other hand, can remove layers of soot without anyone's ever having to touch the surface.
Specifically, sea level ozone is formed when sunlight splits nitrogen dioxide into nitric oxide and atomic oxygen
. The atomic oxygen
reacts with molecular oxygen to form ozone.
Whiteshell Laboratories, working in partnership with ASPEN Systems -- a Massachusetts company that creates polymers for satellite manufacturing -- has created a new polymer that should withstand atomic oxygen
. The key Manitoba ingredient, according to Saunders, is that Whiteshell Laboratories can generate a beam of pure electricity which creates a molecular change within the polymer.
The LDEF experiments gathered information on space radiation, atomic oxygen
, meteoroids, space debris, space systems, and life sciences.
In the conditions we used, the primary reactive species was atomic oxygen
, present as approximately 10 to 20 percent of the particles in the reaction gas chamber.
Inside, a hot tungsten filament was heated to 1500 degrees Celsius, causing the oxygen molecules to dissociate into atomic oxygen
. The highly reactive oxygen atoms then uniformly inserted into the graphene lattice.
The results indicate that as negative charges of the nano clusters increase, the molecular/ atomic oxygen
adsorption models as well as the most stable adsorptive status vary.
Bruce Banks and Sharon Miller at the Electro-Physics Branch of NASA Glenn Research Center, Cleveland, developed the Atomic Oxygen
System for Art Restoration to restore paintings.
One possible explanation: once excited, atomic oxygen
can take 5 or 6 minutes to emit a photon of red light -- long enough for the atom to drift off into space or be "quenched" by striking the moon's surface.
The spectrograph recorded far-ultraviolet emissions from atomic oxygen
in Europa's atmosphere.
However, the rest of the density anomalies are attributable to lower-than-expected upper thermospheric temperatures and low concentrations of atomic oxygen
near the base of the thermosphere.
