We introduce a high-performance Python-based XAS denoising package called XASDenoise, which implements our newly developed stationarity warping method and advanced denoising techniques based on Gaussian process regression and a convolutional autoencoder.

A comprehensive database for experimental X-ray absorption spectroscopy data is presented. This integrated and user-friendly platform combines spectrum visualization, raw data processing, spectrum matching and downloading.

High-energy resolved fluorescence-detected X-ray absorption spectroscopy at the uranium L3 edge and relativistic quantum chemistry calculations are combined to study in detail the uranium valence electronic structure in NaUO3, KUO3 and RbUO3. The impact of the structural distortion of the oxygen octahedra around uranium on the contribution of uranium and oxygen states in observed spectral features is discussed.

The OÆSE endstation at EMIL at the BESSY II synchrotron facility in Berlin allows real-time investigation of energy materials through operando X-ray absorption spectroscopy. The possibility to use soft, tender, and hard X-rays combined with versatile operando sample environments enables the study of a wide range of energy materials under relevant operation conditions.

Web-CONEXS is introduced – a web application hosted on ISPyB at Diamond Light Source, which provides a platform for modelling XAS spectra based on minimal user input.
