The electronic structure and chemical state of an interface/surface is determined by the surrounding environment, which in last term rules its properties. These properties, as chemical composition and chemical state, are of main importance because they determine the performance of the electrode under relevant working conditions. However, there are many difficulties, ascribed to the complexity of these systems, that hinder the total understanding of the electrochemical processes. Synchrotron X-ray based techniques have emerged as an important tool for the characterization, being non-destructive methods that provide relevant information of a material of interest in an element specific way. Unfortunately, these techniques present sometimes a lot of challenges to overcome when applied to the study of electrochemical systems under operando conditions. They are hardly compatible with liquids especially in the soft X-ray regime and when using electrons. However, in the last years there have been a lot of efforts to use these state-of-theart techniques for different electrochemical studies with a huge potential impact in our society, i.e. for H generation/storage, CO valorization, batteries etc. This symposium will focus on in situ/operando techniques developed for the investigation of electrochemical energy materials under relevant working conditions using X-ray synchrotron-based techniques.

Rosa Arrigo (WoS Researcher ID L-6676-2016) is lecturer in Inorganic Chemistry at the University of Salford in Manchester (UK) and honorary research scientist at the UK’ s synchrotron facility Diamond Light Source. Her research interests are focused on the design of innovative processes and nanostructured systems for decarbonization technologies in green chemistry and energy storage and conversion. Her research strategy consists of establishing molecular level structure-function relationships through the controlled synthesis of tailored materials, testing and thorough structural characterisation, including but not limited to the extensive use of innovative in situ synchrotron-based techniques such as X-ray photoelectron spectroscopy and X-ray absorption fine structure spectroscopy. Current projects focus the conversion of carbon dioxide and H2 production. Recently, she is investigating the host/guest chemistry in metal-organic frameworks for the delivery of Aspergillus derived drugs and in CO2 capture.

Carlo Marini studied at University of Roma “Sapienza” (Italy) where he defended the PhD in Physics in 2010. In the same year he joined the ESRF synchrotron of Grenoble (France) first as post-doc and then as junior scientist (2013) at the BM23 and ID24 beamlines. In February 2014 he joined ALBA synchrotron as second scientist at CLAESS beamline. Since 2023 he is beamline responsible of NOTOS. His scientific activity has been initially focused on the characterization of 3d metal functional materials and then it opened to the study of catalysis and in particular bimetallic nanoparticles, with a special interest to the interplay between structural and electronic properties shown by these systems. During his research, he developed a multi techniques approach which includes X ray absorption, X ray emission, X ray diffraction, Raman, Infrared, High Pressure and theoretical simulations. In 17 years of research, he produced more than 140 publications in international journals reaching a final H-index 30.
Peter Strasser is the chaired professor of �Electrochemistry for energy conversion and storage� at the Chemical Engineering Division of the Department of Chemistry at the Technical University of Berlin. Prior to his appointment, he was Professor at the Department of Chemical and Biomolecular Engineering at the University of Houston. Before moving to Houston, Prof. Strasser served as Senior Member of staff at Symyx Technologies, Inc., Santa Clara, USA. In 1999, Prof. Strasser earned his doctoral degree in Physical Chemistry and Electrochemistry from the �Fritz-Haber-Institute� of the Max-Planck-Society, Berlin, Germany, under the direction of the 2007 Chemistry Nobel Laureate, Professor Gerhard Ertl. In the same year, he was awarded the �Otto-Hahn Research Medal� by the Max-Planck Society. In 1996, Dr. Strasser was visiting scientist with Sony Central Research, Yokohama, Japan. He studied chemistry at Stanford University, the University of Tuebingen, and the University of Pisa, Italy. Professor Strasser is interested in the fundamental Materials Science and Catalysis of electrified liquid solid interfaces, in particular for renewable energy conversion, energy storage, production of fuels and chemicals.
