Towards machine‐learning‐based on‐the‐fly analysis of neutron reflectometry

Journal of Applied Crystallography, Volume 59, Issue 3, Page 765-773, June 2026.
An automated machine‐learning‐based processing and analysis workflow for neutron reflectometry data is presented. The approach has been successfully used for on‐the‐fly analysis during an experiment at the Institut Laue–Langevin (Grenoble, France) and can be adapted to work at other neutron facilities seeking to enable real‐time feedback‐driven ...

Soil Crack Width Controls Preferential Flow Velocity Through Drag Partitioning

Geophysical Research Letters, Volume 53, Issue 10, 28 May 2026.
Abstract Preferential flow within soil cracks influences land surface hydrological processes, yet direct quantifying preferential flow velocity (PFV) remains challenging. Here, we develop a method for high‐resolution monitoring and quantifying PFV in soil cracks using optical frequency domain reflectometry (OFDR).

Direct Mode‐Resolved Measurement of Interfacial Phonon Transport by Acoustic Phonon Reflectometry

Advanced Materials Interfaces, Volume 13, Issue 10, 19 May 2026.
We introduce a novel analysis, acoustic phonon reflectometry, that measures the mode‐resolved phonon reflection coefficient at semiconductor interfaces. In aluminum nitride, we observe excellent agreement with the acoustic mismatch model across three distinct interfaces.
