Angewandte Chemie, Volume 138, Issue 24, 8 June 2026.Lithium‐sulfur (Li‐S) batteries contain various NMR‐active nuclear isotopes, including 7Li, 6Li and 33S, which are sensitive to the different chemical reactions that occur during battery cycling. Herein, we use a combination of lithium and sulfur operando NMR spectroscopy to provide new insights at the molecular level, fundamental understanding being ...

Emergent Chaos‐Like Dynamics of Spin–Orbit‐Torque‐Driven Magnetic Transitions
Small, EarlyView.By combining anisotropy‐engineered nanometer‐scale nucleation sites with time‐resolved x‐ray holography and micromagnetic modeling, magnetization dynamics are directly imaged, revealing chaos‐like fluctuations and skyrmion shedding and highlighting the intrinsic complexity of spin‐orbit torque driven systems.

Liquid Crystal Polymers as Intrinsically Magnetic and Programmable Soft Materials for Microrobotics
Small, EarlyView.Liquid crystal polymers (LCPs) are proposed as intrinsically magnetic, programmable, soft materials for microrobotics. Magnetic torque‐driven manipulation of LCP microobjects is achieved and characterized in terms of the step‐out frequency, reaching ∼0.6 Hz in a ∼250 mT magnetic field. The orientation of LCP microobjects in the magnetic field and their

Boreas, EarlyView.The Megalopolis Basin is located in the central Peloponnese (Greece), a region that is situated along one of the primary Pleistocene biogeographical corridors for intracontinental hominin migration. The basin comprises several hundred metres of Plio‐Pleistocene sediments alternating between clastics and lignites.

Magnetic properties of geraisites, the first tektite strewn field identified in Brazil
Meteoritics &Planetary Science, EarlyView.Abstract Geraisites are a newly recognized class of tektite from Brazil. They occur as centimeter‐sized, elongated to subspherical bodies scattered across surface gravel and shallow subsurface layers within a ~90‐km‐long strewn field extending between the municipalities of São João do Paraíso and Curral de Dentro, near the border between the states of ...
