Denoising framework for X-ray absorption spectroscopy data [PDF]
Journal of Synchrotron RadiationX-ray absorption spectroscopy (XAS) is a powerful tool for probing the structural and electronic properties of materials, but its analysis is often challenging due to the low signal-to-noise ratio of the XAS spectra.

Biological X-ray absorption spectroscopy and metalloproteomics
Journal of Synchrotron Radiation, 2009 In the past seven years the size of the known protein sequence universe has been rapidly expanding. At present, more then five million entries are included in the UniProtKB/TrEMBL protein database. In this context, a retrospective evaluation of recent X-ray absorption studies is undertaken to assess its potential role in metalloproteomics ...

Calcite Nanocrystals Investigated Using X-ray Absorption Spectroscopy
Crystals, 2021 For the present work, calcite nanocrystals were grown by annealing precursors at 500 °C. These precursors were obtained by three different thermal schemes. Among these schemes, two involve heating at 100 °C for 16 h and 16 + 24 h, respectively.

X-ray absorption spectroscopy [PDF]
Photosynthesis Research, 2009 This review gives a brief description of the theory and application of X-ray absorption spectroscopy, both X-ray absorption near-edge structure (XANES) and extended X-ray absorption fine structure (EXAFS), especially, pertaining to photosynthesis. The advantages and limitations of the methods are discussed.
