In‐situ Scanning Transmission X‐Ray Microscopy of Catalytic Solids and Related Nanomaterials [PDF]
ChemPhysChem, 2010 AbstractThe present status of in‐situ scanning transmission X‐ray microscopy (STXM) is reviewed, with an emphasis on the abilities of the STXM technique in comparison with electron microscopy. The experimental aspects and interpretation of X‐ray absorption spectroscopy (XAS) are briefly introduced and the experimental boundary conditions that determine

Enhanced Imaging in Scanning Transmission X-Ray Microscopy Assisted by Ptychography
NanomaterialsScanning 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.

Identification and characterisation of individual nanoplastics by scanning transmission X-ray microscopy (STXM) [PDF]
Journal of Hazardous Materials, 2022 Nanoplastics (NP) are of environmental and human health concern. We tested a novel NP extraction method and scanning transmission X-ray spectro-microscopy (STXM) in combination with near-edge X-ray absorption fine-structure spectroscopy (NEXAFS) to image and identify individual NP in environmental and food matrices.

Scanning Transmission X‐Ray Microscopy as a Novel Tool to Probe Colloidal and Photonic Crystals [PDF]
Small, 2011 AbstractPhotonic crystals consisting of nano‐ to micrometer‐sized building blocks, such as multiple sorts of colloids, have recently received widespread attention. It remains a challenge, however, to adequately probe the internal crystal structure and the corresponding deformations that inhibit the proper functioning of such materials. It is shown that

A bidirectional scanning method for scanning transmission X-ray microscopy [PDF]
Journal of Synchrotron Radiation, 2021 Scanning mode is a key factor for the comprehensive performance, including imaging efficiency, of scanning transmission X-ray microscopy (STXM). Herein is presented a bidirectional scanning method designed for STXM with an S-shaped moving track. In this method, artificially designed ramp waves are generated by a piezo-stage controller to control the ...

Hessian Splines for Scanning Transmission X-Ray Microscopy
2020 IEEE 17th International Symposium on Biomedical Imaging (ISBI), 2020 Scanning transmission X-ray microscopy (STXM) produces images in which each pixel value is related to the measured attenuation of an X-ray beam. In practice, the location of the illuminated region does not exactly match the desired uniform pixel grid. This error can be measured using an interferometer.
