The effect of physical barriers under a raised house on mosquito entry: an experimental study in rural Gambia

Malaria Journal
Background Anopheles gambiae, the major malaria mosquito in sub-Saharan Africa, feed largely indoors at night. Raising a house off the ground with no barriers underneath reduces mosquito-house entry.

Uncovering hidden bias in neutron diffraction residual strain measurements

Journal of Applied Crystallography, EarlyView.
This work demonstrates that diffraction‐based residual strain calculations and uncertainty estimates depend on how grain populations are sub‐sampled, with important implications for interpreting residual stresses in heterogeneous materials with fine‐scale microstructure and strain gradients.When calculating residual strain via neutron or X‐ray ...

Mobile electromagnetic levitator for time‐resolved in situ X‐ray diffraction studies of high‐temperature phase transformations

Journal of Synchrotron Radiation, EarlyView.
A mobile electromagnetic levitator combined with time‐resolved synchrotron X‐ray diffraction enables in situ studies of high‐temperature phase transformations without container‐induced contamination and reveals the first direct observation of metastable phase formation in undercooled Fe–Co alloys.In situ observations of high‐temperature transformations,

Synchrotron beamline setup enabling quasi‐simultaneous PXRD and XANES measurements: case study of Fischer–Tropsch catalyst reduction at 60 bar

Journal of Synchrotron Radiation, EarlyView.
This paper presents a beamline setup that allows the combination of in situ powder X‐ray diffraction (PXRD) and X‐ray absorption near‐edge structure (XANES) measurements within a single experimental cycle to investigate cobalt catalyst structures and properties under real conditions.Powder X‐ray diffraction (PXRD) and X‐ray absorption near‐edge ...

Design and commissioning of a new synchrotron beamline dedicated to X‐ray footprinting mass spectrometry

Journal of Synchrotron Radiation, EarlyView.
A dedicated beamline at the Advanced Light Source synchrotron has been opened and commissioned for X‐ray footprinting mass spectrometry.The structural biology method of X‐ray footprinting mass spectrometry (XFMS) is available at two national synchrotron beamlines in the USA: one at the Advanced Light Source (ALS) on the West Coast and the other at the ...

Effect of oxygen and nanoparticles on human skin and colon cells exposed to synchrotron‐based X‐ray FLASH beams

Journal of Synchrotron Radiation, EarlyView.
Most cancer patients will be treated by radiotherapy, and recent findings suggest that delivering radiation at `FLASH' ultra‐high dose rates reduces damage to healthy tissues while still damaging the tumour. This project experimentally validates the reduced healthy tissue damage of FLASH radiotherapy on cells using synchrotron‐based beams, which will ...

GIWAXS using microbeam applied in halide perovskite films for high spectral resolution and mapping capability

Journal of Synchrotron Radiation, EarlyView.
This article demonstrates that microbeam GIWAXS (µ‐GIWAXS) effectively overcomes the distorting footprint effects of conventional GIWAXS analysis of perovskite films. This advancement not only delivers higher reciprocal‐space resolution data but also unlocks the unique capability to spatially map microstructural inhomogeneity, which is vital for the ...
