  abstract     = {{Metal oxide nanoparticles are widely used in catalysis, photovoltaics, and gas sensing, where surface structure and oxidation state strongly influence performance. This work investigates how carrier gas composition, combined with in-flight heating, can be used to control the surface properties of metal oxide nanoparticles generated via the gas-phase method, spark ablation. Sn, Zn, and Al nanoparticles were characterized using in-flight X-ray photoelectron spectroscopy (XPS) at the MAX IV synchrotron radiation facility, enabling near real-time measurement of suspended particles under oxidizing (N₂ + O₂), inert (N₂ and Ar), and potentially reducing (N₂ + H₂ and Ar + H₂) gas environments, without introducing potential changes associated with particle deposition and <br/>storage. To support the interpretation of the XPS results, the particle size distributions, spark energy and frequency, and compaction behaviour were studied, providing insight into how material properties and generation conditions affect surface chemistry.}},
