Motion‐compensated diffusion encoding gradients for segmented thick‐slab 3D magnetic resonance diffusion‐weighted imaging of the brain

Medical Physics, Volume 53, Issue 3, March 2026.
Abstract Background Routine clinical magnetic resonance diffusion‐weighted imaging (DWI) is generally performed with 2D echo planar sequences. A single thick‐slab 3D approach could offer higher signal‐to‐noise ratio and better slice resolution. This has not been adopted due to the difficulty to avoid motion‐induced phase error that interfere with multi‐

Sub‐Micrometer Ag Particles Boost Luminescence and Thermal Stability of Perovskite Quantum Dot Phosphors for Light‐Emitting Diodes

Rare Metals, Volume 45, Issue 3, March 2026.
ABSTRACT Perovskite quantum dots (QDs) have been considered as promising emitters for lighting and display applications, but they suffer from poor thermal stability under operation. Herein, we introduce sub‐micrometer Ag particles to simultaneously enhance the luminescence intensity and thermal stability of perovskite QDs.

Controlled Source DAS Coupling Tests: Implications for Unburied Deployment on the Moon and Earth

Earth and Space Science, Volume 13, Issue 3, March 2026.
Abstract Moonquake recordings are key to understanding the Moon's internal structure, yet existing data from the Apollo missions are limited. Distributed Acoustic Sensing (DAS) offers a promising alternative to conventional seismometers for future lunar seismic monitoring, particularly due to its robustness and suitability for high‐scattering ...

Formation of Continuum Emission Structures Associated With the Aurora

Journal of Geophysical Research: Space Physics, Volume 131, Issue 3, March 2026.
Abstract Recent observations enabled by improvements in geospace remote‐sensing instrumentation have revealed the spatial structure of continuum emissions that appear to be associated with the aurora, but little is known about the formation and drivers of these structures.
