Satellite-particle control technique based on gas-flow-regulation during gas atomization process
Fenmo yejin jishu, 2022 Gas atomization (GA) is an essential method for the preparation of metal powders specifically used in the additive manufacturing. However, there are plenty of “satellites” among the metal powders prepared by GA. The existence of these satellite particles

Atomic hydrogen: the quantum gas [PDF]
Physics World, 1995 It was a complete surprise when Isaac Silvera and his colleagues at the University of Amsterdam observed the existence of a remarkably stable gas of hydrogen atoms in 1979. They found that a gas of the so-called "atom of atoms" could be confined for several minutes in a cryogenic test cell close to absolute zero, provided that the walls were coated ...
