A Novel Data‐Driven Probabilistic Approach for Consequence Specific Urban Flood Risk Mapping

open access: yesWater Resources Research, Volume 62, Issue 2, February 2026.
Abstract Urban floods are increasing in frequency, causing significant socio‐economic impacts, especially where risk mitigation is limited. Conventional hydrologic and hydraulic models identify flood‐prone areas but demand extensive data and computation, whereas risk mapping offers a data‐efficient alternative by integrating elements at risk such as ...

R32 partial condensation inside a brazed plate heat exchanger

open access: yesInternational Journal of Refrigeration, 2013
Abstract This paper presents recent measurements of heat transfer coefficient obtained during condensation of R32 inside a commercial brazed plate heat exchanger (BPHE). The experimental data show the effect of refrigerant mass velocity, vapor quality, temperature difference (saturation-to-wall) and inlet vapor superheating.

Nutzen der 3d‐4f Koordination: Molekulares Quanten‐Feder‐Magnet‐Verhalten in axialen Ni2Ln Komplexen

open access: yesAngewandte Chemie, Volume 138, Issue 5, 28 January 2026.
Wir berichten über heterotrimetallische Ni2Ln Komplexe, die Austauschfeder‐Magnete auf molekularer Ebene nachahmen. CASSCF Rechnungen zeigen kollineare Anisotropieachsen, während µSQUID Studien langsame Relaxation und offene Hysterese in Ni2Tb, Ni2Dy, und Ni2Ho offenbaren.
