Prof. Dr. Iztok Arčon


Prof. dr. Iztok Arčon is full professor for the field of physics, employed at the University of Nova Gorica, Laboratory for quantum optics, holding a position of the dean of Grauate school

His main research field is analysis of atomic and molecular structure of new functional materials (different catalysts and photocatalysts, cathode materials for Li-ion, Li-sulphur and Mg-sulphur batteries, ferroelectric and ferromagnetic ceramics, …) and analysis of environmental pollution (soil, water and plants), with X-ray absorption spectroscopy with synchrotron radiation (methods XANES, EXAFS), In addition, he uses synchrotron radiation for experimental study of multielectron photoexcitations in free and bound atoms, to provide information on collective motion of electrons in the atomic system, and exact atomic absorption background in EXAFS spectra.  Since 1989 he obtained with coworkers over sixty research projects at different European synchrotron radiation laboratories (PETRA III at DESY, Hamburg; Elettra, Trieste; ESRF, Grenoble; Alba in Barcelona; Soleil, and previously Lure, Paris), and performed experiments with advanced sychrotron radiation techniques.  Until 2022 he published more than 200 scientific papers in reviews with high impact factor and  his work is highly cited (over 3500 citations). His Hirsch index is 30.

To mention some outstanding scientific results: he performed in-operando XAS analysis of different cathodes materials for Li-ion, and Li- and Mg-Sulphur batteries with high energy density, to monitor the change of valence and local structure of sulphur in the cathode material. The operando XAS results revealed dynamics of electrochemical processes during battery operation. He performed in-situ XAS analysis of different (photo)catalytic materials for water cleaning and catalysts for other technological process, which revealed the active sites during the photo and thermo catalytic reactions and explained the mechanisms responsible for optimal performance of the catalysts. To resolve detoxification problems because of environmental pollution with heavy metals (Hg, Cd, Pb, Se, As, ..), and to increase concentrations of essential elements (Mn, Fe, Zn, Cu)  in the edible plant parts, he used a combination of X-ray spectroscopy and sub-micron X-ray microscopy to efficiently assess metal bioavailability and their toxicity, and gain more knowledge on the mechanisms of metal uptake, accumulation and detoxification in living organisms.

He received The Jožef Stefan Golden Emblem Prize Award in 1996 for his PhD thesis research work. In 2006 he was awarded the national “Zois award” for outstanding achievements in the field of X-ray absorption spectroscopy, and in 2020 he received Pregl Award of the National institute of Chemistry for Exceptional Achievements in the field of chemistry and related disciplines.

He is a delegate for Slovenia in European User Synchrotorn Organisatio (ESUO). In last ten years he was a member of project evaluation committees at four synchrotron radiation facilities (PETRA III at DESY, CERI-ERIC at Elettra, at ESRF and at Soleil).
