Dr. Yudhajit Bhattacharjee (Leibniz Institute of Polymer Research Dresden - IPF Dresden) has been honored with the Best Poster Award at the 2D MXene Symposium during the 2025 MRS Fall Meeting in Boston. Several PhD students funded by Research Training Group (RTG) 2767 are involved in the paper - it's one of our first joint PhD publications.

Dr. Bhattacharjee’s award-winning research focuses on the molecular engineering of Ti₃C₂Tₓ MXenes, introducing innovative strategies for tuning MXene interfaces through controlled molecular crosslinking. This approach enables precise control over inter-layer spacing and electron transport properties, as confirmed by advanced characterization techniques and theoretical calculations. The study demonstrates that such molecularly engineered MXene architectures can be effectively utilized in chemiresistive sensing devices, offering tunable response characteristics for advanced sensor applications .

The findings have been recently published in the journal Advanced Functional Materials, highlighting the potential impact of this work on the development of next-generation MXene-based technologies.

On October 21, Nadia Günther defended her PhD thesis titled “From Colloids to Devices: I-III-VI₂ Nanocrystals for Novel Field-Effect Transistors”. She received the highest honor summa cum laude. Nadia was the first person of the 1st generation of RTG students to finish her doctoral studies.

The presentation lasted 30 minutes, followed by a 30-minute discussion on the dissertation work. The examination committee consisted of Prof. Alexander Eychmüller (first examiner), Prof. Karl Leo (second examiner), Prof. Carolin Murawski (third examiner), and Prof. Ulrich Rant, who served as chair.

On October 27th, Christian Roßner presented his habilitation work titled "Polymer-Grafted Gold (Supra-)Colloids: From Mechanisms of Formation to Dynamic Soft Matter," which he developed together with his team and under the mentorship of Professor Andreas Fery since beginning his independent scientific career in Dresden in November 2019. Focusing on the synthesis of "hairy" colloids, their targeted assembly into higher-order structures, and the design of functional supracolloids, this habilitation project is directly linked to the research activities within the RTG and forms the foundation for tackling challenges in the fields of (bio-)sensing and energy materials.

In addition to Prof. Fery, the commission members were Professors Stefan Kaskel (Chair), Anjana Devi, Xinliang Feng, Thomas Heine, Jens-Uwe Sommer, Inez Weidinger, and Jan Weigand.

Dr. Roßner is Group Leader for "Hybrid Nanomaterials" at Leibniz Institute of Polymer Research Dresden (IPF), and Assistant Professor at UCT Prague. Within the RTG 2767, he covers this topic as an Principal Investigator.

In their latest article, our Principal Investigator Dr. Hendrik Schlicke (SchlickeLab, Leibniz-Institut für Polymerforschung Dresden — IPF) and his colleagues demonstrate how MXenes can benefit from concepts familiar to colloidal chemists: By employing ligand functionalization and molecular cross-linking they created ink-processable stable dispersions and tunable hybrid materials from Ti3C2Tx MXenes, which show promising properties for electronics and sensing applications.

The article was just published in Advanced Functional Materials.

Out now in Nature Nanotechnology, Dr. Quinn A. Besford (IPF Dresden) leads a timely and urgent commentary on the rising dangers of artificial intelligence (AI) in nanomaterials science and what can be done to address them.

The piece draws attention to a concerning new reality: even experienced researchers are increasingly unable to distinguish authentic nanomaterial microscopy images from AI-generated forgeries. This blurring of truth and fabrication raises profound concerns for the integrity of scientific publishing, peer review, and public trust in nanoscience.
