Congratulations to Prof. Dr. Carsten Schuck, David Lemli, Tim Buskasper and Lukas Schulte for breaking the Guinness World Record (GWR) for the Smallest QR Code! The tiny QR code, spanning only 5.38 square micrometres, is seven times smaller than a human red blood cell and about 20 times smaller than the previous world record. It was fabricated to promote the cleanroom lab course Foundations of Nanofabrication, part of our teaching program, and aims to inspire interest in nanofabrication among physics students.

This impressive achievement was made possible through the efforts of our research group, in partnership with the Münster Nanofabrication Facility (MNF), which, as part of the University of Münster, provides students with access to cutting-edge nanotechnology.

We would like to thank Hitachi High-Tech Europe GmbH in Krefeld, for serving as an independent surveyor to ensure unbiased measurement of the QR code following GWR guidelines.

Check out the October issue of wissen|leben, where the cleanroom lab course offered to physics master’s students is highlighted. The article provides a fascinating glimpse into the hands-on experience gained during the Foundations of Nanofabrication course, part of our teaching program. Students work in the Münster Nanofabrication Facility (MNF), creating nanometer-scale materials like OLEDs in cleanroom conditions. The piece details how the lab course enhances students' understanding of nanotechnology and practical skills with advanced equipment. Text available in German only!

Photo-Chemical Activation Functions for Neural Networks

Our joint work with the AG Risse and the AG Ravoo on using Azobenzene-based Photo-Chemical Activation Functions in Optical Artificial Neural Networks is now published in Advanced Intelligent Systems! We use a physically motivated model and obtain a tuneable yet interpretable activiation function that enables solving classification tasks such as XOR, Circle, MNIST and FashionMNIST with a neural network. This is an important stepping stone for understanding Intelligent Matter.

Alex' and Tobias' work in ACS Photonics

Alex and Tobias report the integration of colloidal quantum dots with nanophotonic waveguides in ACS Photonics with contributions from the AG Bratschitschand AG Pernice. They managed to both excite the quantum dots and collect single fluorescence photons via Ta2O5-on-insulator waveguides and report on how the approach can be scaled to larger system size.
