Nano- and micro-scale imaging of rocks with X-ray ptychography

Christoph Eckart Schrank, Michael W. M. Jones, Cameron M. Kewish, Grant A. van Riessen et autres

X-ray ptychography is a lensless, coherent-diffraction imaging technique developed over the last 20 years that affords 10-nm resolution for optically thick specimens1. It reconstructs the optical transmission function (OTF) of a sample from raster-scanned overlapping 2D transmission diffraction patterns through iterative phase …

Migration and spawning strategies of hilsa shad (Tenualosa ilisha, Clupeidae) in the Ayeyarwady River revealed by otolith chemistry

An Vi Vu, John C. Conallin, Zau Lunn, Nyein Chan et autres

Hilsa shad ( Tenualosa ilisha ) is an ecologically and economically important fish species in the Indo-Pacific region, yet its migration and spawning behaviour remains poorly in Myanmar. This study investigates hilsa migration and spawning strategies in the Ayeyarwady River using otolith …

Physical optics study of mask roughness in EUV interference lithography

Jerome B. M. Knappett, Cameron M. Kewish, Blair Haydon, Grant A. van Riessen

A physical optics model of a soft X-ray (SXR) interference lithography system operating at a wavelength of 6.7 nm was used to evaluate the individual effects of mask surface roughness and line-edge roughness (LER) on aerial image quality. Aerial images were simulated …

Unravelling cyclic fault healing in carbonates: A natural example for the interaction of mechanical and fluid-mediated processes

Berit Ina Schwichtenberg, Alfons Berger, Marco Herwegh, Christoph Eckart Schrank et autres

During the interseismic phase, faults regain frictional strength through a process commonly referred to as fault healing. Key mechanisms include contact welding by dissolution-precipitation creep and cementation by mineral precipitation in fluid-rich environments. While much research has focused on experimental investigations of …

Mapping nano- and microporosity in ductile shear zones with X-ray ptychography

Nicole M. Bishop, Christoph Eckart Schrank, Michael L. Jones, Cameron M. Kewish et autres

Petrological and geochemical evidence demonstrates that mylonitic ductile shear zones transport significant amounts of fluids through the lithosphere. Because of the lack of percolating pore networks in exhumed mylonitic rocks, it has been hypothesised that most of the fluid pathways in ductile …

Real-space nanostructure via correlation analysis of scanning microfocus x-ray diffraction data

Stefan Paporakis, Michael Hasset, Patrick W. Adams, Jack Binns et autres

Fluctuation scattering techniques (also known as x-ray cross-correlation analysis techniques) aim to extract 3D structural information from scanning diffraction experiments via statistical analysis methods, typically based on correlating diffracted intensities [ 1]. There are opportunities to study the nanostructure of disordered and …

Structural and chemical mapping of Au–Co(OH) 2 electrocatalytic films shows the formation of ordered Au crystallites and the suppression of Co oxidation

Rusha Kamar, Cameron M. Kewish, Anthony Peter O'Mullane

Simultaneous micro X-ray diffraction (XRD) and X-ray absorption near edge spectroscopy (XANES) mapping highlights transition metal oxide catalysts reconstructing both chemically and structurally during the oxygen evolution reaction (OER).
