Water has been and still is one of our main fields in research. Especially in the finished project of the DFG-research group 436 there was a very close and successful cooperation between researchers in Bochum, Dortmund, Darmstadt and Rostock. The project entitled: Polymorphism, Dynamic and Function of Water at molecular surfaces was financed by the german research foundation from 2001 to 2007. A special issue was published by ChemPhysChem for the final meeting of the group in 2008 in Dortmund, Bommerholz (ChemPhysChem, 2008, 9, 18).

And even though ionic liquids moved more and more into the focus during the last years, water reseach is still advancing by the support of classical laboratory work but also with the help of "computer chemistry". Some recent publications are dealing with specific ion effects on sturcture and dynamics of water beayond the first hydration shell (Angew. Chem., 123:368, 2011) as well as with the existence of free OH groups in water and aqueous salt solutions (J. Chem. Phys., 135:117101, 2011).
