Pikosekunden‐Stabilisierung von übertragenen Ladungsträgern an plasmonischen Metall‐Molekül‐Grenzflächen

open access: yesAngewandte Chemie, Volume 138, Issue 1, 2 January 2026.
Ladungs‐ und Wärmeübertragungsprozesse zwischen plasmonischen Nanopartikeln und adsorbierten molekularen Monoschichten werden mittels ultraschneller Infrarotspektroskopie beobachtet. Die Analyse der Absorption freier Ladungsträger und der Schwingungssignale zeigt, dass überlaufende Ladungsträger stabilisiert werden, wodurch sich ihre Lebensdauer auf ...

A pan‐European citizen science study shows population size, climate and land use are related to biased morph ratios in the heterostylous plant Primula veris

open access: yesJournal of Ecology, Volume 114, Issue 1, January 2026.
A large‐scale citizen science study involving thousands of cowslip (Primula veris) observations from all over Europe revealed an unexpected prevalence of S‐morphs over L‐morphs, which was influenced by climatic as well as land use factors. Furthermore, general morph ratios were often unbalanced with the strongest shifts occurring in smaller populations.

Space‐Time Boundary Elements on Graded Meshes for 3D Elastodynamics

open access: yesInternational Journal for Numerical Methods in Engineering, Volume 126, Issue 20, 30 October 2025.
ABSTRACT The solution to the elastodynamic equations in the exterior of a polygonal or polyhedral domain or a screen exhibits singularities at corners and edges. This paper presents a space‐time boundary element method in 3D on algebraically graded meshes to resolve these singularities, based on recently obtained error estimates for the weakly singular

Effiziente Methoden zur Analyse der Elektronenstruktur für Katalysatorscreenings: Projektionsbasierte Einbettungstheorie für Zwischenprodukte der CO2 Reduktionsreaktion

open access: yesAngewandte Chemie, Volume 137, Issue 38, September 15, 2025.
Diese Arbeit zeigt, wie die projektionsbasierte Einbettungstheorie erfolgreich angewendet werden kann, um chemische Reaktionen auf Metalloberflächen zu untersuchen, indem sie Richtlinien für eine angemessene Systempartitionierung und eine geeignete Beschreibung der Wechselwirkungen zwischen den Subsystemen liefert.

Impact of Fiber Orientation in Electrospun PLA Scaffolds on Fluid Dynamics in a Custom Microfluidic Device

open access: yesAdvanced Healthcare Materials, Volume 14, Issue 25, September 26, 2025.
Fiber orientation in electrospun scaffolds affects permeability and fluid dynamics in microfluidic devices. Combining experimental data with computational fluid dynamic simulations, we show that aligned fibers enhance flow uniformity, reduce pressure and shear stress variability.
