Mit allen Sinnen forschen - Girls' Day am INM

(PresseBox) (Saarbrücken, )
Am 23. April forschen Schülerinnen der Klassenstufe sieben bis zehn am INM - Leibniz-Institut für Neue Materialien mit allen Sinnen. Sie entschlüsseln die Duftstoffe mitgebrachter Kosmetikproben und stellen im Labor Beschichtungen her, denen kratzige Fingernägel nichts anhaben können.

Dieser Dampf wird durch eine dünne Säule geschickt. Im Säuleninneren befindet sich ein dünner Film, an dem die verschiedenen Duftmoleküle unterschiedlich stark haften bleiben. Sie erreichen also zu unterschiedlichen Zeiten das Säulenende. Dort erkennt ein Messfühler, um welche Tcaixhpvnalr iy mpoe mtdtw hevpsdf.
