Seitliche π‐Koordination einer C≡C‐Dreifachbindung an Technetium forciert durch den As,CC,As Alkin‐Pinzetten‐Liganden 1,2‐Bis(2‐(Diisopropylarsaneyl)‐4‐(Trifluormethyl)phenyl)Ethin

Angewandte Chemie, EarlyView.
Technetium‐Alkin‐Komplexe konnten jahrzehntelang nicht isoliert werden, obwohl es zahlreiche Berichte über benachbarte Elemente gab. Der einzige Hinweis auf ihre Existenz war die Isolierung von Vinylidencarbenen oder deren Folgeprodukten. Stabile, kristalline Tc(III)‐ und Tc(V)‐Alkin‐Komplexe (sowie deren Re‐Analoga) eines auf Tolan basierenden As,CC ...

High pressure study of sodium trihydride

Frontiers in Chemistry
The reactivity between NaH and H2 has been investigated through a series of high-temperature experiments up to pressures of 78 GPa in diamond anvil cells combined with first principles calculations. Powder X-ray diffraction measurements show that heating

Search for superconducting icosahedral hydrides via coordination number engineering

Communications Physics
Superconducting hydrides provides a possible route to hunt for high-temperature superconductors. Recent high-throughput calculations suggest hydrides, which are combined by alkali or alkali-earth elements and hydrogen-and-transition-metal units, as ...

An Integrated Solution to FIB-Induced Hydride Artifacts in Pure Zirconium

Micromachines
The preparation method of transmission electron microscopy (TEM) samples for pure zirconium was successfully executed using a focused ion beam (FIB) system. These samples unveiled artifact hydrides induced during the FIB sample preparation process, which

Mimicking a Light‐Harvesting Complex to Accelerate Photooxidation in Asymmetric Lipid Membrane Nanoreactors

Angewandte Chemie International Edition, EarlyView.
Biomimetic liposome nanoreactors mimicking natural light‐harvesting complexes enable efficient photooxidation of NADH. Membrane‐anchored fluorescein transfers energy via FRET to membrane anchored eosin Y, oxidizing NADH. While symmetric membranes show little improvement, asymmetric chromophore distribution enhances photooxidation rates by up to 27 ...

High‐Temperature Superconductivity in Perovskite Hydride Below 10 GPa

Advanced Science
Hydrogen and hydride materials have long been considered promising materials for high‐temperature superconductivity. However, the extreme pressures required for the metallization of hydrogen‐based superconductors limit their applications.

Isolation and Reactivity of a Square‐Planar Trisamido Silane

Angewandte Chemie International Edition, EarlyView.
We report the synthesis and comprehensive characterisation of a square‐planar Si(+IV) hydride supported by an unsymmetric, trianionic and dearomatised N,N,N‐pincer ligand. This system enables element–ligand cooperative reactivity as an alternative to silicon‐centred redox chemistry, illuminating a largely unexplored regime in high‐valent silicon ...

A Synergistic Inhibitor Development Strategy Against Human UDP‐Galactose‐4‐Epimerase

Angewandte Chemie International Edition, EarlyView.
The epimerase GalE is crucial for the biosynthesis of cancer‐relevant O‐GalNAc glycans. Here, we employ orthogonal, structurally enabled small molecule fragment screens to yield both covalent and non‐covalent inhibitors against GalE within no more than 22 elaborated compounds.
