Dem Rätsel der Materie auf der Spur
Forschende haben an der Quelle für ultrakalte Neutronen des PSI eine Eigenschaft des Neutrons so genau wie noch nie vermessen: sein elektrisches Dipolmoment. Denn bis heute wird nach einer Erklärung gesucht, weshalb es nach dem Urknall mehr Materie als Antimaterie gab.
Kurzfilm eines magnetischen Nanowirbels
Mit einer neu entwickelten Untersuchungsmethode konnten Forschende die magnetische Struktur im Inneren eines Materials mit Nanometer-Auflösung abbilden. Ihnen gelang ein kurzer «Film» aus sieben Bildern, der erstmalig in 3-D zeigt, wie sich winzige Wirbel der Magnetisierung tief im Inneren eines Materials verändern.
Anna Sótér starts Ambizione fellowship

TecDay: LMX meets Hohe Promenade
TecDay is an SATW initiative that was developed at the Kantonsschule Limmattal in 2007 and has since been rolled out to more than 60 secondary schools across Switzerland.
