A Kapitza–Dirac–Talbot–Lau interferometer for highly polarizable molecules [PDF]

Nature Physics, 2007
Research on matter waves is a thriving field of quantum physics and has recently stimulated many investigations with electrons, neutrons, atoms, Bose-condensed ensembles, cold clusters and hot molecules. Coherence experiments with complex objects are of interest for exploring the transition to classical physics, for measuring molecular properties and ...

Comparison of data processing techniques for single-grating x-ray Talbot interferometer data [PDF]

, 2017
The phase-stepping (PS) mode of X-ray Grating Talbot interferometer (XGTI) data processing technique can yield high-spatial resolution images, albeit with lower throughput since each projection of a tomogram requires at least five phase-stepping images ...

Tunable X-ray dark-field imaging for sub-resolution feature size quantification in porous media

Scientific Reports, 2021
X-ray computed micro-tomography typically involves a trade-off between sample size and resolution, complicating the study at a micrometer scale of representative volumes of materials with broad feature size distributions (e.g. natural stones). X-ray dark-

Transport of Peroxyacyl Nitrates (PANs) Across Northern Hemisphere Ocean Basins From Satellite Observations

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 6, 28 March 2026.
Abstract We leverage global satellite observations of Peroxyacyl Nitrates (PANs) from the Cross‐track Infrared Sounder (CrIS) on the Suomi National Polar‐orbiting Partnership satellite to evaluate seasonal and interannual variations of intercontinental transport in the Northern Hemisphere between 2016 and 2022.
