Hello everyone, A couple of days ago I posted an update containing a link to a paper which has been published in Nature Chemistry. Unfortunately this link was behind a paywall, which caused a bit of consternation. But never fear! I had a word with the Librarian (the word was ook, obviously) and found a non-paywalled link for all my lovely supporters. Here it is: http://rdcu.be/gYzr (Note: you'll probably need a computer to access this; it's unlikely to work from mobile devices.) Enjoy! Ook! #speakhisname #GNUTerryPratchett
