Abstract

original image

Eingesperrte Ionen: Die hohe Eindringtiefe und Empfindlichkeit der Neutronenstreuung auf Isotopensubstitution wurde genutzt, um Änderungen in der Ionenkonzentration eines porösen Kohlenstoffmaterials als Funktion der angelegten Spannung und der Porengröße zu bestimmen. Abhängig von den Lösungsmitteleigenschaften und den Wechselwirkungen zwischen dem Lösungsmittel und der Porenwand ist die Ionenabsorption verstärkt oder reduziert.
