Core Facility

Bildgebung von Materialsystemen

Die 3D‐Visualisierung von komplexen funktionalen und adaptiven (Mikro)Systemen in Natur und Technik gehört zu den zentralen Herausforderungen im Rahmen der Grundlagenforschung an adaptiven und bioinspirierten Technologien sowie der Erforschung von Funktionsprinzipien in biologischen Systemen als Ideengeber für neue technische Entwicklungen.

Durch bereits vorhandene und zusätzlich beschaffte Geräte ist es möglich ein Speziallabor für Mikroskopie und Tomografie von Materialien verbunden mit einem FIT Kompetenznetz 3D-Visualisierung  zu etablieren.

Für weitere Fragen zu den anfallenden Kosten (Gebührenordnung), zur Benutzungsordnung und zum Anmeldeverfahren wenden Sie sich bitte an die Leitung der Core Facility.
