Reduced heat flow in light water (H2O) due to heavy water (D2O)

The flow of heat, from top to bottom, in a column of light water can be decreased by over 1000% with the addition of heavy water. A column of light water cools from 25 C to 0 C in 11 hours, however, with the addition of heavy water it takes more than 100 hours. There is a concentration dependence where the cooling time increases as the concentration of added (D2O) increases, with a near maximum being reached with as little as 2% of (D2O) added. This phenomenon will not occur if the water is mixed after the heavy water is added.Comment: 18 pages, 22 figures, PD

Pressure Dependence of Energetic (160 keV) Focused Electron Beams Arising From Heated or Cooled (LiNbO3) Pyroelectric Crystals

A new effect, gas amplification of electron energy is reported here; namely when a cylindrical pyroelectric crystal such as (LiNbO3) is contained in a concentric cylindrical chamber and is heated and then allowed to cool in a dilute gas the maximum energy of the resultant focused electron beam more than doubles as the pressure increases from 0.05 to 4 mTorr for seven different gases.Comment: 5 pages, 5 figures, pd
