Wenn sich molekulare Sterne reiben

Jülicher Physiker berechnen Reibungsverhalten von Makromolekülen

(PresseBox) (Jülich, )
Reibung ist allgegenwärtig in unserem täglichen Leben, aber oft unerwünscht, weil sie Wärme verursachen und Material verschleißen kann. Die physikalischen Ursachen der verschiedenen Reibungsphänomene sowie der reibungsmindernden Effekte von Schmierstoffen im Detail zu verstehen, ist deshalb Ziel der Physik. Wie Reibungsgeschwindigkeit und Kraftaufwand bei einzelnen Makromolekülen in wässriger Lösung zusammenhängen, fanden Jülicher Forscher nun mit Hilfe von numerischen Methoden und Simulationen heraus. Sie sehen darin einen ersten Schritt zu einem besseren Verständnis von Reibungsprozessen, wie sie etwa in menschlichen Gelenken oder Prothesen zu finden sind. Ihre Ergebnisse sind in der aktuellen Ausgabe der Fachzeitschrift "Physical Review Letters" nachzulesen.
