STXM-NEXAFS of individual titanate-based nanoribbon

2008
In recent years, many low dimensional TiO2-materials, such as nanowires, nanotubes, and nanorods have been successively synthesized. These novel nanostructures bring to reality the possibility to fine tune chemical reactivity as the system structure and the occupation of the outermost energy levels can be tuned by changing preparation parameters.

STXM-XANES and computational investigations of adsorption of per- and polyfluoroalkyl substances on modified clay

Water Research, 2021
The study investigated molecular mechanisms of per- and polyfluoroalkyl substances (PFAS) on a surfactant modified clay (SMC), which rivals or exceeds the performance of granular activated carbon in removing long-chain PFAS from contaminated water.

STXM imaging with a configured detector

Journal de Physique IV (Proceedings), 2003
The use of a segmented, transmitted-x-ray detector in the scanning transmission x-ray microscope (STXM) allows a number of different image modes to be realised simultaneously, from a single scan of the specimen. A software-configurable detector system that is based on an 80x80-element CCD array has been tested using the STXM on ID21 at the ESRF.

In-situ STXM characterization of Cu/Cu2O electrocatalysts for CO2 reduction

AIP Conference Proceedings, 2023
Scanning Transmission X-ray microscopy (STXM) is a synchrotron-based soft X-ray spectra-microscopic technique which provides chemically selective imaging via spatially resolved X-ray absorption spectroscopy. In-situ STXM of electrocatalysts provides imaging and spectroscopic information at different time / voltage points in the electrochemical process,

STXM analysis of fungal soil aggregation

2020
<p>Understanding soil’s C sink potential is crucial to support soil management that increases its long-term carbon storage. Soil aggregate formation is known to be a main factor for long-term C sequestration, as C becomes physically protected, or “hidden”, within an increasingly complex ...

Human Neocortex Layer Features Evaluated by PIXE, STIM, and STXM Techniques

Biological Trace Element Research, 2022
The human neocortex has a cytoarchitecture composed of six layers with an intrinsic organization that relates to afferent and efferent pathways for a high functional specialization. Various histological, neurochemical, and connectional techniques have been used to study these cortical layers.

Mechanical Engineering of a Cryo STXM at CLS

2017
A Scanning Transmission X-ray Microscope (STXM) is a useful imaging tool, but its application to certain types of samples is limited by significant rates of x-ray damage to the sample. Cooling samples to liquid nitrogen temperatures can delay radiation damage, but must be done in a vacuum environment to prevent rapid formation of ice on the sample. The

Configured detector system for STXM imaging

AIP Conference Proceedings, 2000
A configured detector system based on an 80×80 element x-ray sensitive CCD array has been developed to replace the conventional transmitted x-ray detector used in the scanning transmission x-ray microscope. This from of detector allows a flexible choice of imaging modes to be made simultaneously from only a single scan of the sample.

STXM Characterization of PEM Fuel Cell Catalyst Layers

ECS Transactions, 2012
The synchrotron based scanning transmission soft X-ray microscopy (STXM) utilizing near edge X-ray absorption fine structure (NEXAFS) is a novel technique for characterization of membrane electrode assembly (MEA) components in proton exchange membrane fuel cells (PEMFC).
