A Thermodynamic Framework for Turing‐Type Instabilities in Porous Media: Part I Theory

open access: yesGeochemistry, Geophysics, Geosystems, Volume 27, Issue 3, March 2026.
Abstract Pattern formation in geological materials is commonly described using analogies to Turing‐type reaction–diffusion systems, yet a unifying thermodynamic explanation remains elusive. Here we develop a multiscale, thermodynamically consistent framework for pattern‐forming instabilities in porous media undergoing coupled thermo–hydro–mechanical ...

Low‐Concentration Electrolytes Based on Weakly Coordinating Anions for Applications in Lithium‐Ion‐Batteries and Lithium‐Metal‐Batteries

open access: yesAngewandte Chemie, Volume 138, Issue 6, 2 February 2026.
Big is beautiful? The performance of 0.2 M low concentration lithium electrolytes with large weakly coordinating anions [Al{OC(CF3)3}4]− and [Ga(C2F5)4]− in low viscosity ortho‐difluorobenzene solution is tested in comparison to standard 1.0 M as well as diluted 0.2 M carbonate‐based electrolytes with Li[PF6] conducting salt.

A Thermodynamic Framework for Turing‐Type Instabilities in Porous Media: Part II Applications

open access: yesGeochemistry, Geophysics, Geosystems, Volume 27, Issue 3, March 2026.
Abstract Compaction bands, desiccation cracks, and melt segregation structures are geological patterns relying on the same fundamental manifestations of a universal Turing‐type instability mechanism, as predicted by the thermodynamically consistent reaction–cross‐diffusion framework developed in Part I (Regenauer‐Lieb et al., 2025, https://doi.org/10 ...

Phase‐Space Synchronization Driven by Moon‐Magnetosphere Coupling in Gas Giants

open access: yesJournal of Geophysical Research: Space Physics, Volume 131, Issue 3, March 2026.
Abstract We present a new theoretical framework to describe the rapid and spatially localized loss of energetic particles in planetary radiation belts, focusing on interactions between gas giant magnetospheres and their moons. Observations show that flux depletions—known as microsignatures—often refill on timescales comparable to a single drift period,

Mononuclear Molybdenum and Tungsten Phosphine Complexes for Catalytic Ammonia Synthesis: Development of the pentaPod Concept

open access: yesChemPhysChem, Volume 27, Issue 4, 25 February 2026.
The pentaPod (P5) concept unites tridentate and tripodal fragments to form molybdenum and tungsten catalytic Chatt‐type complexes for N2‐to‐NH3 reduction. Two pentaPod ligands, P5Me and P5Pln, are available with either two dimethylphosphine or phospholano (Pln) groups. The complexes enable the investigation of reactivity differences in N2 reduction and,
