Multi-Orbital Charge Transfer into Nonplanar Cycloarenes Revealed with CO-Functionalized Tips
On-surface synthesis has allowed for the tuneable preparation of numerous molecular systems with variable properties. Recently, we demonstrated the highly selective synthesis of kekulene (>99%) on Cu(111) and isokekulene (92%) on Cu(110) from the same molecular precursor (Ruan et al., Angew. Chem. Int. Ed. 2025, e202509932). Scanning tunneling microscopy with CO-functionalized tips can identify the single molecules on the basis of their geometric structure at a low coverage on Cu(110), but it a…

Eh les gars, presque toutes les comparaisons avec l'Allemagne sont louches. Quand on nous dit que seulement 5% d'affections longue durée dans la sécu en Allemagne contre 20% en France, ils oublient de dire que la sécu allemande rembourse 100% et non pas 70% comme en France (et 90% en Alsace/Moselle). Donc on compare des pommes et des poires. Donc, le coût de la maladie longue durée pour l'individu est totalement différent.

Budget 2026 : 20% des Français sont-ils concernés par des affections de longue durée contre 5% des Allemands,
Pour justifier certaines mesures d'économies envisagées dans le domaine de la santé, le Premier ministre a comparé des données concernant la prise en charge des malades chroniques.

tiDAS: a time invariant approximation of the Delay and Sum algorithm for biomedical ultrasound PSF reconstructions
Ultrasound imaging is a real-time diagnostic modality that reconstructs acoustic signals into visual representations of internal body structures. A key component in this process is beamforming, with the Delay and Sum (DAS) algorithm being a standard due to its balance between simplicity and effectiveness. However, the computational cost of DAS can be a limiting factor, especially in real-time scenarios where fast frame reconstruction is essential. In this work, we introduce a time-invariant app…
