Professor Michael Naguib, from Tulane University in the USA, is one of the discoverers of a new class of 2D materials: MXenes are characterised by a puff pastry-like structure and have many applications, such as in the production of green hydrogen or as storage media for electrical energy. During his Humboldt Research Award in 2025, Professor Naguib is working with Prof Volker Presser at the Leibniz Institute for New Materials in Saarbrücken and with Dr Tristan Petit at HZB.
Michael Naguib, Ph.D., is an Ken & Ruth Arnold Early Career Professor in Science and Engineering at Tulane University in New Orleans, Louisiana, USA. He is a leading expert in the field of two-dimensional materials. His research group at Tulane University focuses on the synthesis and characterization of novel nanomaterials, including MXenes and Transition Metal Carbo-chalcogenides, for energy and environmental applications.
He completed his doctorate in 2014 at Drexel University, where he was involved in the discovery of a new class of materials. At that time, he tested MAX phases (layered ceramics) as electrode materials for lithium batteries. To create more space for the lithium ions, he used an acid and discovered that the “A” layers in the MAX phases had been selectively removed, transforming the remaining MX layers into a structure that, under a scanning electron microscope, resembled puff pastry: MXene.
To date, a wide range of MXenes have been synthesised. Their applications are also highly diverse: MXenes can be used as electrodes for energy storage devices, in catalysis and as sensors for medical applications. ‘I am delighted to deepen our collaboration with Tristan Petit and his team at HZB,’ says Naguib. ‘We will be discussing several fundamental questions regarding our novel materials and preparing a series of experiments to conduct at BESSY II to help us answering these questions.’

“Tailoring 2D Materials from the Atomic to Nanoscale for Electrochemical Energy Applications”
- Nanosilver as an electrocatalyst for CO₂ reductionVia electrolysis, CO2 can be reduced to CO, a raw material for further chemical products such as fuels. Within the GreenQuest Project, an internation team led by HZB chemist Prashanth Menezes has now systematically investigated catalyst layers made of silver nanoparticles, varying both the size of the particles and their density. The best yield was achieved with nanoparticles with diameters of around 10 nm, which were loosely distributed. Furthermore, they demonstrated how the economic efficiency of the electrochemical cell can be enhanced by integrating an additional chemical reaction at the anode, enabling the simultaneous production of a valuable formic acid, hydrogen, and CO in one device.
- Spin waves inside a nano-oscillator imaged for the first timeFor the first time, researchers have directly imaged the magnetisation dynamics inside a spin Hall nano-oscillator — a nanoscale device that converts direct current into tunable microwave signals and is a promising building block for energy-efficient wireless communication and brain-inspired computing. A Swedish–German team led by the University of Gothenburg and Helmholtz-Zentrum Berlin (HZB) achieved this using time-resolved scanning transmission X-ray microscopy at the MAXYMUS instrument at BESSY II. The results, now published in Advanced Materials, reveal spin-wave features that had escaped previous, indirect measurement techniques.
- Joint power instead of duplicate structures:Berlin’s research community is further advancing its research excellence by establishing a high-performance, cross-institutional infrastructure for data and AI. With a joint agreement signed on 18 September 2026, the Berlin University Alliance (BUA), the Helmholtz-Zentrum Berlin (HZB) and the Zuse Institute Berlin (ZIB) are paving the way for a joint data science and AI centre in Berlin-Dahlem and Adlershof.
