Dynamic Confinement Approach for High Metal Loading Single‐Atom Catalysts Based on Covalent Organic Frameworks

Angewandte Chemie, EarlyView.
We introduced a new synthetic strategy for the preparation of high metal loading crystalline single‐atom catalysts based on covalent organic frameworks with atomically distributed Pd ions and metal contents of up to 22.2 wt%. Theoretical simulations reveal that the crystalline framework dynamically confines Pd atoms between different binding sites ...

Electron-momentum dependence of electron-phonon coupling underlies dramatic phonon renormalization in YNi2B2C

Nature Communications, 2022
Phonon anomalies are commonly attributed to Fermi-surface nesting or phonon anharmonicity, but these mechanisms do not apply in all cases. Here, the authors propose a new mechanism based on electron-momentum-dependent electron-phonon coupling in the case

50 Years of Giese Reaction – a Personal View

Angewandte Chemie, EarlyView.
The Giese‐Reaction celebrates its 50. Birthday, it is a cyclic radical chain reaction centered around C,C‐bond formation in a three component synthesis. This minireview speaks about the birth of the name‐reaction, explains how the complete understanding of its reaction mechanism stimulates new methods in organic synthesis, and why it can proceed in ...

Description and phylogenetic relationships of a new species of Torvoneustes (Crocodylomorpha, Thalattosuchia) from the Kimmeridgian of Switzerland [PDF]

PeerJ, 2023
Metriorhynchids are marine crocodylomorphs found across Jurassic and Lower Cretaceous deposits of Europe and Central and South America. Despite being one of the oldest fossil families named in paleontology, the phylogenetic relationships within ...

How Positively Valenced Health Messages can Foster Information Selection: Evidence from Two Experiments

Frontiers in Communication, 2021
Objective: Positively valenced appeals have received comparably less attention than negative appeals. However, messages utilizing negative emotions have been repeatedly criticized, and research has demonstrated the beneficial effects of applying positive

"-Et, ô ces voix d’enfants chantant dans la coupole!" Dimension symbolique de l’architecture et Mises en scène contemporaines du Parsifal de Richard Wagner [PDF]

Muzikologija, 2013
Parsifal représente un dilemme entre la sensualité et l’aspiration à la pureté, que Wagner a notamment synthétisé visuellement dans ses indications de décors.

Field-induced ultrafast modulation of Rashba coupling at room temperature in ferroelectric α-GeTe(111)

Nature Communications, 2022
The ferroelectric material α-GeTe(111) is an excellent playground for spin-to charge conversion due to its strong Rashba coupling. Here, the authors reveal an ultrafast modulation of its Rashba coupling on the femtosecond timescale.
