Kooperative Redox‐Katalyse der N2O‐Zersetzung mittels auf Co3O4 geträgerten RhOx‐ und CeOx‐Spezies mit kurzreichweitiger Wechselwirkung

Angewandte Chemie, Volume 138, Issue 34, 17 August 2026.
A short‐range Rh‐O‐Co‐O‐Ce interfacial moiety drives low‐temperature N2O decomposition via a cooperative redox cycle. Operando modulated‐excitation XAS with phase‐sensitive detection (ME‐XAS+PSD) tracks rapid, reversible Rh oxidation coupled to Co reduction. Combined kinetics and DFT rationalize the activity trends and identify the Rh‐O‐Co interface as

Experimental investigation on post‐installed anchorages with cast‐in anchor reinforcement under tension loading

Structural Concrete, Volume 27, Issue 4, Page 6156-6175, August 2026.
Abstract Anchors are used to connect different structural and non‐structural components to reinforced concrete structures. Anchorages when subjected to tension loading might fail in different failure modes, with concrete cone breakout (CCB) being one of the most common.

Combining Policy Instruments and Local Measures to Promote Agrobiodiversity Combiner instruments de politique et mesures locales pour promouvoir l'agrobiodiversité Kombination von politischen Instrumenten und lokalen Maßnahmen zur Förderung der Agrobiodiversität

EuroChoices, Volume 25, Issue 2, Page 51-57, August 2026.
Summary Agrobiodiversity is in decline. While the literature highlights the role of public policy in this process, a research gap remains concerning how policies can help reverse this trend by providing economic support to farms that value crop and varietal diversity. Based on desk research and expert interviews, this article first provides an overview
