Spin‐Crossover in a Dinuclear Iron(II) Complex on Highly Oriented Pyrolytic Graphite: An X‐Ray Absorption Spectroscopy Study

open access: yesChemPhysChem, EarlyView.
This study investigates a spin‐crossover dinuclear Fe(II) complex deposited as a thin film under ultrahigh‐vacuum conditions by a pulsed layer injection technique. Its temperature‐dependent switching behavior, light‐induced excited spin‐state trapping, soft‐X‐ray‐induced excited spin‐state trapping, and temperature‐ and light‐induced spin crossover ...

Physics‐based inverse modeling of battery degradation with Bayesian methods

open access: yesChemSusChem, Accepted Article.
To further improve Lithium‐ion batteries (LiBs), a profound understanding of complex battery processes is crucial. Physical models offer understanding but are difficult to validate and parameterize. Therefore, automated machine‐learning methods (ML) are necessary to evaluate models with experimental data. Bayesian methods, e.g., Expectation Propagation

Asymmetric Benzene Sulfonamide Sodium Salt Enabling Stable Cycling in Solid‐State Sodium Metal Batteries

open access: yesChemSusChem, EarlyView.
A novel sodium salt, sodium (benzenesulfonyl)(trifluoromethanesulfonyl) imide, is developed for all‐solid‐state sodium metal batteries. It offers a high sodium‐ion transference number and stability with sodium metal . Combined with poly(ethylene oxide), it forms strong solid polymer electrolytes that suppress dendrite growth and polarization.

2. The Theory of Special Relativity

open access: yes, 1958
Albert Einstein (1879-1955) published his first work on relativity in 1905, the same year in which he published remarkable papers on Brownian motion and the photoelectric effect.

The Zr8O6 Secondary Building Unit and Porphyrin Linker Catalyze Light‐Driven H2 Evolution in Porphyrin‐Based Metal Organic Frameworks

open access: yesChemSusChem, EarlyView.
Zr8O6‐based metal–organic frameworks (porous coordination network PCN 221 M, M = 2 H, Zn, Ni, ZnNi) with metalloporphyrin linkers are explored for H2 evolution under 405 nm light emitting diode irradiation. PCN 221 Zn exhibits the highest activity with a turnover number (TON) of 4 via dual charge transfer pathways. Spectroscopy revealed Zn‐TCPP acts as
