Short bio

 

PhD student in the field of correlative SEM/EDX/Raman microscopy. His research is primarily concerned with various corrosion mechanisms, but as part of his employment at the Graz Center for Electron Microscopy (ZFE), he is also involved in commissioned research. In 2018 he completed his master’s degree at the Karl Franzens University in Graz, specializing in experimental physics.

 

 

Abstract

Napoleon I, 3D-printed fungi, a Louvre at the nanoscale and art made of bread

An Electron Microscopy Institute meets Art
(Almost) perfect fake? A presumed autograph of Napoleon I from 1815

At the beginning of 2021, the FELMI-ZFE-Graz was contacted by the Styrian Provincial Archive to verify an autograph of Napoleon I – the so-called Lettre de reddition – from 1815 for authenticity. In this work correlative light microscopy, scanning electron microscopy (SEM), and Raman microscopy were used to prove that this letter is falsifiable.

Conservation of Bread (& Art)

When artwork is made of food items or biological materials, the preservation of these materials is of vital importance. In the presented work, different methods to preserve bread were compared using SEM, energy dispersive X-Ray spectrometry (EDX), and Raman spectroscopy.

From Electron Microscopy to 3D Printing

The exhibition Fungi – Food, Poison and Mythology in the Museum Wiesbaden, Germany shows a special highlight: macroscopic 3D reconstructions of spores based on the 3D data of serial block-face SEM.

Fabrication of a Nano-Louvre via 3D Nanoprinting (FEBID)

Larger 3D prints of small things are great, but tiny 3D prints of big things are just that much great. So why not print the Louvre pyramid so small, that it theoretically fits 1,000,000 times on a €1 coin?

3D Nanofabrication with Focused Electron Beam Induced Deposition (FEBID) is a leading edge method for nanotechnology. The Christian Doppler Laboratory for Direct–Write Fabrication of 3D Nano–Probes (DEFINE) at the FELMI-ZFE showed that this method can also be used to create art directly out of the electron microscope.
