Dank neuer Erkenntnisse bald Supraleitung bei Raumtemperatur?

Unerwartete Wasserstoffdichte in Metallhydrid

(PresseBox) (Dübendorf, )
Ein Forscherteam aus der Schweiz, den USA und Polen hat eine einzigartig hohe Dichte von Wasserstoffatomen in einem Metallhydrid nachgewiesen. Die kleineren Abstände zwischen den Atomen könnten es ermöglichen, deutlich mehr Wasserstoff in das Material zu packen – bis zu einem Punkt, an dem es bei Raumtemperatur und Normaldruck zum Supraleiter werden könnte.

Die Wissenschaftler führten im «Oak Ridge National Laboratory» (ORNL) im US-Bundesstaat Tennessee Neutronenstreuexperimente an Zirkonium-Vanadium-Hydrid bei atmosphärischem Druck und bei Temperaturen von bis zu -23 Grad Celsius durch. Die Messungen ergaben überraschend kleine Wasserstoff-Wasserstoff-Atomabständen, die nur 1,6 Angström (weniger als ein Millionstel Millimeter) betragen, im Vergleich zu
