Thermodynamic modeling of the no-vent fill methodology for transferring cryogens in low gravity [PDF]
The filling of tanks with cryogens in the low-gravity environment of space poses many technical challenges. Chief among these is the inability to vent only vapor from the tank as the filling proceeds.

Cold gas dynamic spraying of titanium coatings [PDF]
Cold gas dynamic spraying, CGDS, is a relatively new technique used to deposit materials onto the surface of a substrate. It differs to the majority of other thermal spray techniques as the substrate and particles are not exposed to high temperatures during the spraying process.
