CFD Investigation on Movement Features of Hydrogen Bubble under Microgravity Environment
Energies, 2022 A designed cryogenic upper stage adopted liquid hydrogen and liquid oxygen (LH2/LO2) as an aerospace propellant. During a zero-gravity coast period in space, the wall heat leakage into the delivery tube could induce liquid propellant evaporation and two ...

Research on the life-limiting sputtering mechanism of 30 cm ion thruster
AIP Advances, 2022 “Pits-and-grooves” patterns on the downstream accelerator grid surface had a severe effect on the thruster life; however, the sputtering patterns on the decelerator grid upstream surface were also observed after the thruster worked for over 3000 h ...

Cryogenic measurement of the optical absorption coefficient in sapphire crystals at 1.064(micro)m for the Large-scale Cryogenic Gravitational wave Telescope [PDF]
, 2001 We have applied laser calorimetry to the measurement of optical absorption in mono-crystalline sapphire at cryogenic temperatures. Sapphire is a promising candidate for the mirror substrates of the Large-scale Cryogenic Gravitational wave Telescope.

Advanced Functional Materials, EarlyView.The separation of Helium gas from natural gas is challenging but highly important. MIL‐116(Ga), a “non‐porous” metal–organic framework is used as a molecular sieve to separate He from CH4. Druse‐like MIL‐116(Ga) particles are integrated into polysulfone mixed matrix membranes.
