Data analysis in spectroscopic STXM

Journal of Electron Spectroscopy and Related Phenomena, 2023
The typical output of a STXM (Scanning Transmission X-ray (spectro)Microscopy) measurement is a data cube consisting of a set of images (measurements of X-ray transmission at a grid of pixels) taken at a sequence of incident energies. As with any experimental measurement, this raw data must be reduced to some standard form and interpreted.

Enhanced Imaging in Scanning Transmission X-Ray Microscopy Assisted by Ptychography [PDF]

Nanomaterials
Scanning transmission X-ray microscopy (STXM) is a direct imaging technique with nanoscale resolution. But its resolution is limited by the spot size on the sample, i.e., by the manufacturing technique of the focusing element.

Evaluation protocol for revealing magnonic contrast in TR-STXM measurements

AIP Advances, 2023
We present a statistically motivated method to extract magnonic contrast from time-resolved scanning transmission x-ray microscopy (TR-STXM) measurements. TR-STXM is an element-specific method for resolving spin-dynamics in space and time.

3D imaging of magnetic domains in Nd2Fe14B using scanning hard X-ray nanotomography [PDF]

Journal of Synchrotron Radiation
Nanoscale structural and electronic heterogeneities are prevalent in condensed matter physics. Investigating these heterogeneities in 3D has become an important task for understanding material properties.

Nanoscale synchrotron x-ray analysis of intranuclear iron in melanised neurons of Parkinson’s substantia nigra [PDF]

Communications Biology
Neuromelanin-pigmented neurons of the substantia nigra are selectively lost during the progression of Parkinson’s disease. These neurons accumulate iron in the disease state, and iron-mediated neuron damage is implicated in cell death.

Soft X-ray radiation-damage studies in PMMA using a cryo-STXM

Journal of Synchrotron Radiation, 2003
Radiation damage sets a fundamental limit for studies with ionizing radiation; cryo-methods are known to ease these limits. Here, measurements on mass loss and the decrease in the C=O bond density as measured by oxygen-edge XANES (NEXAFS) spectroscopy in thin films of poly(methylmethacrylate) (PMMA), studied in a vacuum, are reported.
