Um... I was using degassed solvents for years as a chemist, ever since I first started working in the lab in 1998. The method used back them was semi-permeable glass filter discs. We had to do this because our pumps and solvent lines would get damaged if the gas came out of solution during a pressure change.
The more polar the solvent, the longer it took to degass the solvent, probably because the solvent has an affinity for glass, which is also highly polar. Is this group trying to develop a filter which works better?
BTW - Detergents often don't clean clothes as well as we think they do. They contain flourescent dyes that cause clothes to look really white. That's why clothes, printer paper, and other treated white objects glow under ultraviolet radiation ("black light").
For those looking for a device strictly for reading, the new Kobo is a nice little option. It's small enough to slip into a pocket, can do more with a PDF than the competition, and at $129, it's $10 cheaper than both the Nook and Kindle WiFi.
