Neptunium, with its rich redox chemistry, has a special position in the chemistry of actinides. With a decades-long history of development of aqueous separation methods for used nuclear fuel (UNF), management of neptunium remains an unresolved issue because of its not clearly defined redox speciation. Neptunium is present in two,...
Radioisotope based power systems have been used for several decades. This
research covers a new concept in the field, a radioisotope micro-power source (RIMS).
A RIMS cell consists of a radioactive source, a hydrogenous material, and a hydrogen
fuel cell.
The fuel cell is powered by hydrogen separated from the...
The atmospheric sodium daytime abundance was measured for
Corvallis, Oregon, using direct absorption of sunlight by atmospheric
sodium atoms, as observed with an optical waveguide spectrum analyzer.
The disadvantage of the spectrum analyzer is that it can't resolve the
sodium D-lines (Its resolving power is 0.5 nm, which is approximately...
