Mercury isotope composition for improved fluorescent lighting efficiency
BackgroundEvery fluorescent light bulb on earth uses a small amount (several milligrams) of mercury. This element has seven naturally occurring isotopes. The opacity of the mercury vapor causes the resonance UV photons emitted by the atoms in a glow discharge plasma to be reabsorbed by adjacent atoms, leading to a much longer effective lifetime or lower...

Generating water from air
Background Air water generation (AWG) is a technology that extracts water molecules from the relative humidity in the atmosphere, passes the condensed water vapor through a filter to produce a drinkable source of water. This type of technology is most beneficial in environments that do not produce large amounts of drinkable water such as arid climates...
