Ein deutsch-amerikanisches Forscherteam hat mit dem Röntgenlaser FLASH des Deutschen Elektronen-Synchrotron DESY erstmals die dreidimensionale Form frei fliegender Nanopartikel bestimmt. Die Teilchen besitzen demnach einen viel größeren Formenreichtum als erwartet, wie die Physikerinnen und Physiker der TU Berlin, der Universität Rostock, des US-Beschleunigerzentrums SLAC und von DESY im Fachblatt "Nature Communications" berichten. Die Ergebnisse weisen darüber hinaus einen Weg zu neuen Forschungsansätzen wie zum Beispiel die direkte Beobachtung schneller Veränderungen in Nanopartikeln.
Nanopartikel sind dabei, unseren Alltag zu erobern. Die Anwendungen dieser winzigen, mit dem Auge nicht wahrnehmbaren Teilchen reichen vom Sonnenschutz über Effektlacke, Farbfilter und elektronische Komponenten bis hin kds Zdzhwltqtpbpuef.
