Element-specific visualization of dynamic magnetic coupling in a Co/Py bilayer microstructure
Scientific Reports, 2022 We present the element-specific and time resolved visualization of uniform ferromagnetic resonance excitations of a Permalloy (Py) disk–Cobalt (Co) stripe bilayer microstructure.

A NeXus/HDF5 based file format for STXM [PDF]
AIP Conference Proceedings, 2016 Scanning Transmission X-ray Microscopy (STXM) is a relatively recent and rapidly growing X-ray imaging technique with niche capabilities that are applicable across a wide set of scientific disciplines. Over the years since its invention, technological progress has allowed a much greater volume and wider variety of data to be recorded, while the ...

3D Chemical and Elemental Imaging by STXM Spectrotomography [PDF]
AIP Conference Proceedings, 2011 Spectrotomography based on the scanning transmission x‐ray microscope (STXM) at the 10ID‐1 spectromicroscopy beamline of the Canadian Light Source was used to study two selected unicellular microorganisms. Spatial distributions of sulphur globules, calcium, protein, and polysaccharide in sulphur‐metabolizing bacteria (Allochromatium vinosum) were ...

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.

Artifacts from manganese reduction in rock samples prepared by focused ion beam (FIB) slicing for X-ray microspectroscopy [PDF]
Geoscientific Instrumentation, Methods and Data Systems, 2019 The spatial distribution of transition metal valence states is of broad interest in the microanalysis of geological and environmental samples. An example is rock varnish, a natural manganese (Mn)-rich rock coating, whose genesis mechanism remains a ...

High Spatial Resolution STXM at 6.2 keV Photon Energy [PDF]
AIP Conference Proceedings, 2010 We report on a zone-doubling technique that bypasses the electron-beam lithography limitations for the production of X-ray diffractive optics and enables the fabrication of Fresnel zone plates with smaller outermost zone widths than other well-established approaches.We have applied this method to manufacture hard X-ray Fresnel zone plates with ...

Journal of Spectral Imaging, 2019 The main storage components of the maize endosperm are starch, proteins and lipids. Starch and proteins are heterogeneously deposited, leading to the formation of vitreous and floury regions at the periphery and at the centre of the endosperm.
