Observation and Coordination Needs for Current, Near‐Future, and Next Generation Earth‐Observing SAR Systems

Earth and Space Science, Volume 13, Issue 5, May 2026.
Abstract This paper summarizes an evaluation by experts of how coordination of Earth‐observing Synthetic Aperture Radar (SAR) missions among the world's space agencies could advance toward game‐changing scientific discoveries and fully realizing SAR's practical capability to address many issues facing society.

“Caterpillar” ULF Waves in the Dusk Side Sub‐Auroral Region: Conjugate Observations With SuperDARN, Arase and Ground Magnetometers

Journal of Geophysical Research: Space Physics, Volume 131, Issue 5, May 2026.
Abstract On 23 November 2022, during exceptionally quiet geomagnetic conditions, a distinct ultra‐low frequency (ULF) wave in the Pc5 band (∼2.4 mHz) was observed in the duskside sub‐auroral region by two Canadian SuperDARN (Super Dual Auroral Radar Network) radars.

Brillouin Scattering Observations of Elastic Behavior Across the Post‐Stishovite Transition Under Deviatoric Stress in Polycrystalline Al‐Bearing Stishovite

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 5, May 2026.
Abstract Stishovite (SiO2), a key phase in subducted mid‐ocean ridge basalt (MORB), undergoes a ferroelastic transition to a CaCl2‐type structure, potentially explaining localized shear wave velocity (VS) anomalies in the shallow to mid‐lower mantle. However, the phase boundary determining this transition remains debated.

Glass bead games: enumeration of possible polytypes based on two stacking vectors and applications to the iron‐ore sinter phases SFCA and SFCA‐I

Acta Crystallographica Section A, Volume 82, Issue 3, Page 145-162, May 2026.
General formulas are presented that allow for the enumeration of polytypes based on translationally equivalent layers and two equivalent arrangements of adjacent layers involving distinct possible stacking vectors, t1 and t2. The results have been applied to the polytypism among two different polysomes of the family of so‐called silico‐ferrites of ...

Progress in Characterizing Curing and Debinding of Ceramic Inks for Stereolithography

Journal of the American Ceramic Society, Volume 109, Issue 5, May 2026.
ABSTRACT During ceramic stereolithography, laser photopolymerization must achieve high and uniform curing of monomers to ensure a crack‐free debinding step. In this study, we present a spatially resolved quantification of curing rate using Fourier transform infrared (FTIR) spectroscopy, relying on advanced deconvolution methods.
