Some Like It Hot –Structural Changes in Extremophile Rubredoxin at 120 °C

Angewandte Chemie, EarlyView.
We reveal the high temperature crystal structure of a hyperthermophilic (Pyrococcus furiosus) rubredoxin at 393 K (120 °C), together with multiple complementary structures down to 100 K. The results are compared with molecular dynamics calculations. Significant changes in H‐bonding are observed.

Decoding Short‐Range Order in Amorphous Two‐Dimensional Nanosheets for Efficient and Durable Ampere‐Level Seawater Electrolysis: A Case Study of Amorphous Ni(OH)2

Advanced Energy Materials, EarlyView.
This work uncovers the atomic‐scale origins of exceptional HER performance in amorphous Ni(OH)2 nanosheets by combining atom probe tomography, DFT simulations, and operando spectroscopy. We identify distinct short‐range‐order motifs that accelerate water dissociation, proton transport, and hydrogen adsorption. Embedding Pt single atoms further enhances

Solvation Entropy as a Lever for Steering the Macroscopic Properties of a Functional Supramolecular Helical Polymer

Angewandte Chemie, EarlyView.
The structural transition between the two fully‐characterized states of a supramolecular helical hydrogen‐bonded polymer (represented as blue and light pink stacks) can be predictably varied over 85 K by changing the nature and amount of cosolvent; entropy of solvation (schematized as solvents of different sizes) is the main lever to tune the ...

Bulk and Surface Reactivity of LiNi0.5Mn1.5O4 in Contact with (Acidic) Water

Advanced Energy and Sustainability Research, EarlyView.
The comprehensive investigation of the influence of (acidic) water on LiNi0.5Mn1.5O4 as cobalt‐free lithium‐ion battery cathode material reveals that such treatment particularly affects a very thin layer at the particle surface, while the bulk material remains unaffected.

Transferring Porosity Across Physical States Using Metal–Organic Cages: Porous Liquids, Glasses, Rubbers, and More

Angewandte Chemie, EarlyView.
Discrete porous metal–organic cages provide a platform to extend porosity beyond crystalline solids. Their peripheral functionality governs inter‐cage interactions and physical state, enabling preservation of intrinsic porosity across liquids, glasses, and rubbers.

Flash Synthesis of High‐Performance Sub‐Micron Low‐Disorder LiNixCoyAlzO2 Cathode Single Crystals

Advanced Energy and Sustainability Research, EarlyView.
A novel and scalable Flash‐Heat and Quench methodology has been developed to synthesize high‐performance LiNi0.8Co0.15Al0.05O2 single crystal cathodes in just minutes versus conventional methods that take multiple hours. X‐ray powder diffraction, neutron powder diffraction, and pair‐distribution and X‐ray absorption spectroscopy have shown low paired ...

Stepwise Reduction of Ruthenium and Growth of Magnetic Structure During Hydrothermal Crystallisation of SrRu2O6 from KRuO4

Angewandte Chemie, EarlyView.
In situ neutron powder diffraction data collected while heating the Ru(VII) reagent KRuO4 in the presence of aqueous Sr2+ reveal the crystallisation of a Ru(VI) oxyhydroxide before the expected Ru(V) oxide; at the same time evolution of antiferromagnetism in the final SrRu2O6 product follows the growth of its crystal structure.
