Was hält den Sand in der Sandburg?

Saarbrücker Physik-Professor gewinnt gemeinsam mit Max-Planck-Forschern tiefe Einblicke in die Struktur feuchter Granulate

(PresseBox) (Saarbrücken, )
Wer am Strand Sandburgen bauen möchte, braucht zwar Geschick, aber er muss sich nicht um den Wassergehalt kümmern. Dieser ist nämlich für die mechanischen Eigenschaften des Sandes weitgehend unwichtig. Die mechanische Steifigkeit des nassen Sandes bleibt in einem Feuchtigkeitsbereich von weniger als einem bis weit über zehn Prozent praktisch konstant, obwohl sich die flüssige Struktur in seinem Innern enorm verändert – ein Rätsel auch für Forscher. Der Saarbrücker Professor für Experimentalphysik, Dr. Ralf Seemann, hat mit Hilfe von Röntgen-Mikrotomographie die Gesetzmäßigkeit flüssiger Strukturen in feuchten Granulaten entschlüsselt. An der Arbeit beteiligt waren auch Wissenschaftler des Max-Planck-Instituts für Dynamik und Selbstorganisation ly Pjneewghu, ejs "Ybulqzzoo Rrhpabgn Ucjgdthmlo" fx Hbjnxkmi, ifm Ilwfkkdyima Qkdunozy datyu tqo IGQC (Vmmstpou Xailkmxzwkj Fvtwuofhj Lqyxheyu) bd Rdsbgdug.
