Towards the Development of Effective Antioxidants—The Molecular Structure and Properties—Part 2 [PDF]

Molecules
The development of effective antioxidants has evolved from descriptive analysis toward a precise, mechanism-driven discipline targeting the molecular “redox switch”.

Chemical and elemental mapping of spent nuclear fuel sections by soft X-ray spectromicroscopy

Journal of Synchrotron Radiation, 2022
Soft X-ray spectromicroscopy at the O K-edge, U N4,5-edges and Ce M4,5-edges has been performed on focused ion beam sections of spent nuclear fuel for the first time, yielding chemical information on the sub-micrometer scale.

Quantifying signal quality in scanning transmission X-ray microscopy

Journal of Synchrotron Radiation, 2022
While the general effects of experimental conditions such as photon flux and sample thickness on the quality of data acquired by scanning transmission X-ray microscopy (STXM) are widely known at a basic level, the specific details are rarely discussed ...

Surface Detection in a STXM Microscope [PDF]

AIP Conference Proceedings, 2011
We have modified scanning transmission x‐ray microscopes (STXM) at the Canadian Light Source and the Advanced Light Source with total electron yield (TEY) detection (TEY‐STXM). This provides improved surface‐sensitive detection, simultaneous with existing bulk‐sensitive transmission detection in the STXM microscopes. We have explored sample‐current and

Soft X-ray characterization of halide perovskite film by scanning transmission X-ray microscopy

Scientific Reports, 2022
Organic–inorganic metal halide perovskites (MHPs) have recently been receiving a lot of attention due to their newfound application in optoelectronic devices, including perovskite solar cells (PSCs) which have reached power conversion efficiencies as ...

Chemical-state distributions in charged LiCoO2 cathode particles visualized by soft X-ray spectromicroscopy

Scientific Reports, 2023
Lithium-ion deintercalation/intercalation during charge/discharge processes is one of the essential reactions that occur in the layered cathodes of lithium-ion batteries, and the performance of the cathode can be expressed as the sum of the reactions ...

3-d chemical imaging with STXM tomography [PDF]

Journal of Physics: Conference Series, 2009
Three dimensional (3-d) chemical mapping using angle scan tomography in a soft X-ray scanning transmission X-ray microscope (STXM) has been applied to quantitative chemical mapping in three dimensions of calcium carbonate biomineralization by planktonic freshwater cyanobacteria of the strain Synechococcus leopoliensis PCC 7942.

Scanning transmission X-ray microscopy study of subcellular granules in human platelets at the carbon K- and calcium L2,3-edges

Platelets, 2022
Platelets and their subcellular components (e.g., dense granules) are essential components in hemostasis. Understanding their chemical heterogeneities at the sub-micrometer scale, particularly their activation during hemostasis and production of platelet-
