Covalent Functionalization of NiFe Layered Double Hydroxides using Tris(Hydroxymethyl)Aminomethane

open access: yesSmall, EarlyView.
Covalent functionalization of NiFe layered double hydroxides with tris(hydroxymethyl)aminomethane enables controlled growth, enhanced structural order, and improved processability. Temporary TRIS anchoring promotes stable water‐based inks and binder‐free electrode fabrication, leading to enhanced oxygen evolution activity and long‐term stability under ...

Outer‐Sphere Tuning of Synthetic Iron–Sulfur Clusters Within Nanoscale Cage Frameworks

open access: yesSmall, EarlyView.
Noncovalent encapsulation of a synthetic iron–sulfur cluster within hydrophobic, naphthalenediimide (NDI)‐paneled cages is shown to lead to dramatic changes in the electronic structure and covalency of the Fe─S core. ABSTRACT As atomic‐scale archetypes for multi‐electron transfer, iron–sulfur clusters are compelling candidates for the design of redox ...

A Review on Jahn–Teller Distortions in Prussian Blue Analogs Molecular Magnets

open access: yesThe Chemical Record, EarlyView.
This review highlights the central role of the Jahn–Teller effect in governing structural stability and electrochemical performance in Prussian blue analogs (PBAs). It establishes clear structure–property relationships and summarizes effective mitigation strategies, providing design guidelines for developing stable, high‐performance PBA‐based energy ...

A unified analytical framework for Mössbauer synchrotron sources

open access: yesJournal of Synchrotron Radiation, EarlyView.
We present a unified analytical framework for Mössbauer synchrotron and X‐ray free‐electron laser sources that provides exact, rotationally invariant expressions for resonance energies and transition probabilities in mixed magnetic dipole–electric quadrupole interactions without Hamiltonian diagonalization.

Experimental Proof to Natural Hydrogen Generated Through Serpentinization of Olivine at Room Temperature and Ambient Pressure With Mechanochemistry

open access: yesChemSusChem, Volume 19, Issue 13, 14 July 2026.
This work shows experimentally the possibility of serpentinization (main mechanism of natural hydrogen) at room temperature and ambient pressure, which may provide the rapidly growing hydrogen economy with inspirations to explore new natural hydrogen deposits and new methods for hydrogen production. Natural hydrogen, or “white hydrogen,” is a promising
