Bimetallic M2B Boride Nanoparticles: A Robust and Recyclable Platform for Dehydration‐Driven Condensation of Aldehydes

ChemistryOpen, Volume 15, Issue 4, April 2026.
Metal borides (MBs) emerge as a versatile class of nanomaterials, featuring high stability and bifunctional Lewis‐acidic/basic active sites. Despite these properties, their applications in CN bond formation are less explored. Herein, we report the first systematic use of M2B‐type boride nanoparticles as efficient and magnetically recoverable catalysts

Modular Donor‐Acceptor Diradicaloids Based on an Electron Deficient N‐Heteroacene Acceptor

Small, Volume 22, Issue 20, 7 April 2026.
This work presents a modular approach to donor‐acceptor‐donor (D‐A‐D) diradicaloids that show systematic evolution of their energy gaps, singlet‐triplet splittings, and diradical character (y). The correlation of (opto)electronic, spin, and magnetic properties with high‐fidelity theoretical investigations provides clear connections between the degree ...

Robust Directional Analysis of Magnetic Microscopy Images Using Non‐Linear Inversion and Iterative Euler Deconvolution

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 4, April 2026.
Abstract In paleomagnetism, bulk measurements of entire samples have traditionally been used to characterize remanent magnetization. While effective, this approach provides only a general directional estimate and cannot resolve spatial variability or magnetization at the grain scale.

New Phoenix Magnetic Anomaly Data Confirms Global Nature of Jurassic Quiet Zone and Provides Insight Into Early Pacific Spreading

Geophysical Research Letters, Volume 53, Issue 6, 28 March 2026.
Abstract We demonstrate the presence of the oldest identifiable marine magnetic anomalies in the Phoenix lineations of the western Pacific based on careful assessment of new data. Recently acquired sea surface magnetic anomalies and multichannel seismic profiles confirm magnetic signals recorded within the Middle‐Jurassic to Early Cretaceous basement ...

Transverse Square Toroidal Vortices with Giant Ferrotoroidic Coupling in Dy‐Bridged Single‐Molecule Toroics

European Journal of Inorganic Chemistry, Volume 29, Issue 9, 20 March 2026.
Single‐molecular toroics (SMTs) offer protected magnetic states for next‐generation quantum technologies. Ab initio and model analyses of Cu2Dy7 and Cu4Dy12 reveal unconventional excited states featuring delocalised toroidal moments that couple into strong ferro‐ and antiferrotoroidic configurations, providing unprecedented magnetic coupling within ...
