I am writing an article about (extraterrestrial) life in "exotic" environments, such as non-water liquids, especially ammonia. I ve searched the Internet and I ve found many interesting facts, but some aspects are still quite unclear. 1) In nonpolar liquid, such as liquid ethane, could something like micelles or bilayers form? I think they could, just like in the water, only inverted, but I am not sure. 2) Many writers think ammonia is not capable to form these membranes of amphiphile molecules. But what about water/ammonia solution? (I think the mixture is much more common in space, so its also more important for exobiology.) 3) Water ice floats. Ammonia ice doesnt. What about mixed form of ice? Does it expand just like water ice does?
