Christmas Night
Twas the night before Christmas when all through the houseNo electrons were flowing through even my mouse.
All devices were plugged in by the chimney with careWith the hope that St. Nikola Tesla would share.

The desorption behavior of deuterium from molybdenum, Mo-0.001 mass %C, Mo-0.06-0.092 mass %B, tungsten and W-0.011 mass %C prepared with arc-melting in Ar-10%D2 was studied using a vacuum desorption method in the temperature range of 533–1152K. The diffusivity of deuterium measured for molybdenum was D=4.97x10−7 exp(−36.7kJ/mol/RT)m2s−1 and D=1.77x10−6 exp(−55.8kJ/mol/RT)m2s−1 for tungsten. The diffusivity of deuterium for both molybdenum and tungsten decreased with an addition of C and B. This decrease was considered due to the trap effect of carbide and boride. The trapping energy estimated was 54 kJ/mol for Mo-C and Mo-B and 82kJ/mol for W-C.
