Flüssig bei -46 Grad: Röntgenlaser untersucht Struktur von unterkühltem Wasser

Erste Strukturanalysen in zuvor unzugänglichem "Niemandsland"

(PresseBox) (Hamburg, )
Mit dem weltstärksten Röntgenlaser hat ein internationales Forscherteam unter Beteiligung von DESY-Wissenschaftlern erstmals die innere Struktur von Wasser erkundet, das trotz einer Kühlung auf minus 46 Grad Celsius noch flüssig ist. Die innere Ordnung von sogenanntem unterkühlten Wasser nimmt demnach mit fallender Temperatur kontinuierlich zu, wie das Team um Forschungsleiter Prof. Anders Nilsson vom US-Beschleunigerzentrum SLAC im britischen Fachjournal "Nature" berichtet. Die Beobachtungen liefern einen ersten Einblick in ein weitgehend unkartiertes "Niemandsland" im Zustandsdiagramm von Wasser und können helfen, verschiedene konkurrierende Theorien zum Verhalten von ultrakaltem Wasser näher einzugrenzen.
