Full of hot air and proud of it: Improving gas storage with MOFs
(PHYSorg.com Chemistry)

Of the four states of matter, gases are the hardest to pin down. Gas molecules move quickly and wildly and don`t like to be confined. When confined, heat and pressure build in the container, and it doesn`t take long before the gas blows the lid off the place, literally. Luckily, gases are superficial. Provide them with an attractive internal surface area, and they`ll pin themselves down in no time. No, it`s not love at first sight, it`s adsorption.
