The polyoxo‐20‐molybdate(VI) wheel [MoVI20O60{AsO2(CH3)2}12]12− (Mo20) can be prepared with or without a central guest in a controlled, cation‐directed fashion. When Mo20 is dissolved in water, it exhibits an immediate, quantitative, and fully reversible solution transformation to a tetranuclear Mo4 cluster, which transforms in the solid state again to

Metal‐Ion Regulated Light‐Free Z→E Isomerization of Azobenzene Glycomacrocycle
Metal ion‐catalyzed Z→E isomerization of photoswitchable azobenzene glycomacrocycle: A new azobenzene‐based glycomacrocycle is capable of forming a 1:1 complex with divalent metal ions in both E‐ and Z‐isomers. The complexes undergo light‐free Z→E isomerization in a timescale spanning from seconds to weeks.

At last, the long‐sought bis(2‐adamantyl)magnesium reagent has been prepared in high yield as a stable tetrahydrofuran/dioxane adduct and fully characterized by x‐ray crystallography. This potent nucleophile outperforms the corresponding Grignard in transmetallation and carbonyl addition reactions, opening new avenues in adamantyl organometallic and ...

We report a cellular membrane‐targeted europium(III) probe, Eu.Chol, that enables selective, time‐resolved detection of peroxynitrite (ONOO−) at the cell membrane interface. Eu.Chol demonstrates efficient incorporation into liposomes and Jurkat cells, with minimal response to H2O2, establishing a modular platform for subcellular ONOO− sensing ...

Modulation of Epigenetic Control by Advanced Molecular Tweezers
Tailored dimeric molecular tweezers recognize the DNA‐binding part of Histone H4 and interrupt the essential histone‐DNA interaction. ABSTRACT This work addresses the question if supramolecular systems can be tailored to interfere with posttranslational modifications (PTM) and epigenetics.

A triangular double‐decker Ni6 complex self‐assembles from Ni(II), TMEDA, and a triphenylene tris dioxolene non‐innocent ligand, with two face‐to‐face tris‐semiquinone decks held by a strong covalent C─C interaction. This rigid scaffold delivers four reversible ligand‐centered redox events: oxidation switches on an intense near‐infrared band and ...

Experimental methods in chemical engineering: Temperature‐programmed oxidation—TPO
Abstract Temperature‐programmed oxidation (TPO) probes the oxidative capacity and redox properties of solid materials—catalysts, metal oxides, perovskites, and carbonaceous deposits. It identifies coke type, distribution, and reactivity. TPO instruments pass an oxidizing gas (diluted O2$$ {\mathrm{O}}_2 $$, air, or less commonly N2O$$ {\mathrm{N}}_2 ...

Development of a rapid antigen-based lateral flow assay for tick-borne spotted fever rickettsioses.
Tick-borne spotted fever rickettsioses (SFRs) continue to cause severe illness and death in otherwise-healthy individuals due to lack of a timely and reliable diagnostic laboratory test.

Investigations Into the Metabolism and Elimination of Tesofensine in Human Urine
This study investigated tesofensine metabolism and urinary elimination after a single 483 μg intake via a dietary supplement. In six volunteers, urine was collected up to 659 h. LC‐HRMS/MS identified four tentative metabolites; maximum urinary concentrations reached 4 ng/mL within 4–48 h.
