A physicist journeying through the small world

The advent of the hydrogen economy is accompanied by increased demand for sensing devices. In our recent paper, we introduce an improvement of WO3-based hydrogen sensors via deposition of CuO nanoclusters that lead to the formation of nano p–n junctions on the surface. The preparation techniques used in the study are scalable and compatible with standard industrial processes. Furthermore, the improvement was achieved without the use of noble metals. The paper is free to access for the next 50 days through this link.



In an overview published in Topics in Catalysis, we report on the recent developments of liquid cells for photoemission electron microscopy. We discuss challenges associated with the design of membranes for photon in - electron out spectroscopy, examine advantages and disadvantages of various cell geometries, and highlight the role of microscopy in a statistical analysis of liquid spectroscopy experiments.
