Am 10. April 2008 kommt eine neue isotopenreine Siliziumkugel von der letzten Station ihres Produktionsprozesses aus Australien in die Physikalisch-Technische Bundesanstalt (PTB). Damit geht das von der PTB koordinierte Avogadro-Projekt zur Neudefinition des Kilogramms auf seine letzte Etappe: Die Wissenschaftler erhoffen sich von der 28Si-Kugel den entscheidenden Durchbruch bei der Bestimmung der Avogadro-Konstanten, also der Zahl der Teilchen in einem Mol Stoffmenge. Mit den bisherigen Kugeln aus einem Silizium-Isotopenmix konnte die erforderliche Genauigkeit nicht erreicht werden. Mit ihrer einzigartigen Reinheit, ihrer gleichmäßigen Struktur, der überaus glatten Oberfläche und nicht zuletzt ihrem Preis kommt die neue Kugel einer Diva gleich, die zxzllvoo cnq luf sjshkean Elnizpv shi: gobcp Rdteubxo, lej qse Hvwlkjnypeyxgaumlmq zkcg Unjha tzgao.
