  • argon
  • And in 1895, while searching for argon, Scottish chemist Sir William Ramsay managed to isolate helium by treating a sample of cleveite with mineral acids. (universetoday.com)
  • bubbles
  • Using their ParRep method on the Titan supercomputer, Los Alamos National Laboratory researchers were able to simulate the surface morphology for helium bubbles growing inside of a fusion reactor's divertor wall for two different growth stages. (phys.org)
  • fusion
  • The superpermeability phenomenon was suggested to use in fusion machines to separate the fuel mixture from helium ashes, to arrange in-vessel fuel recirculation contours and effective evacuation of fuel mixture out of machine exhaust. (ans.org)
  • The by-products of fusion reaction are helium, a harmless gas used to inflate children's balloons, and neutrons. (thedailystar.net)
  • Whereas
  • Whereas we tend to think of Helium as the hilarious gas that does strange things to your voice and allows balloons to float, it is actually a crucial part of our existence. (universetoday.com)
  • form
  • As helium particles bombard the tungsten wall, they begin to form clusters within the material. (phys.org)
  • energy
  • Both methods use the mass difference of the isotopes, which is related to their zero-point energy. (cuvillier.de)
  • The inertness of helium is due to the stability and low energy of it's electron cloud state, where all of its electrons fully occupy 1s orbitals in pairs, none possessing angular momentum and each cancels the other's intrinsic spin. (universetoday.com)
  • exist
  • For some time, helium was believed to exist only in the Sun. However, in 1882, Italian physicist Luigi Palmieri detected helium on Earth when analyzing lava from Mount Vesuvius after it erupted in that year. (universetoday.com)
