Deciphering structural complexity of brain, joint, and muscle tissues using Fourier ptychographic scattered light microscopy

VIEW, EarlyView.
This study introduces Fourier ptychographic scattered light microscopy (FP‐SLM). It combines Fourier ptychographic microscopy (FPM), which images large fields of view with high resolution, and computational scattered light imaging (ComSLI), which visualizes densely interwoven fibers.

Anomalous‐Energy Runaway Electrons Originating in Fast Ionisation Wave During Pulsed Gas Breakdown

High Voltage, EarlyView.
ABSTRACT Anomalous‐energy runaway electrons (RAEs), whose energy exceeds the maximum potential difference across the discharge gap, are widely observed in various plasma phenomena. This study investigates the origination of anomalous‐energy RAEs in fast ionisation waves (FIWs) formed during pulsed gas breakdown.

Eikonal Phase Retrieval: unleashing the potential of fourth‐generation sources for enhanced propagation‐based tomography on biological samples

Journal of Synchrotron Radiation, EarlyView.
A new iterative phase retrieval algorithm, Eikonal Phase Retrieval, tackles large phase gradients and yields higher‐quality propagation‐based X‐ray tomography of strongly heterogeneous biological samples.The evolution of synchrotrons towards higher brilliance beams has increased the possible sample‐to‐detector propagation distances for which the source

A low‐background setup for in situ X‐ray total scattering combined with fast scanning calorimetry

Journal of Synchrotron Radiation, EarlyView.
A setup enabling in situ X‐ray total scattering combined with fast scanning calorimetry is demonstrated at beamline ID15A of the ESRF, allowing for the retrieval of detailed structural evolution with changes in thermodynamic conditions.We demonstrate a setup, combining fast scanning calorimetry with X‐ray total scattering at a synchrotron beamline ...
