Spin Crossover around Room Temperature: Effects of Remote Ligand Symmetry Breaking within Jäger‐Type Iron(II) Complexes

open access: yesZeitschrift für anorganische und allgemeine Chemie, EarlyView.
Remote symmetry breaking in Jäger‐type iron(II) complexes shifts stepwise spin crossover (SCO) profiles to continuous profiles with transition temperatures around room temperature. In a bottom‐up approach, we studied the feedback of slight molecular modifications on the spin crossover (SCO) properties of otherwise structurally conserved iron(II ...

Differentiated by Design? Cross‐Border Cooperation in Europe as Differentiated Integration From Below

open access: yesJCMS: Journal of Common Market Studies, EarlyView.
Abstract Differentiated integration has become a central concept in contemporary theorizing about European integration, reflecting the increasingly multi‐speed, multi‐tier and multi‐menu nature of integration within the European Union (EU). This research note extends the conceptual lens of differentiated integration to the level of cross‐border regions.

Sea Lice (Lepeophtheirus salmonis) Harbour Putative Fish Pathogens: Insights From Illumina and Nanopore Sequencing

open access: yesJournal of Fish Diseases, EarlyView.
ABSTRACT Ectoparasites that penetrate host skin can act as biological or mechanical vectors for pathogens and, in some cases, serve as reservoirs. Crustacean ectoparasites of fish are potential vectors of pathogens, which is especially relevant for obligate pathogens (e.g., Aeromonas salmonicida) with limited seawater survival. Sea lice (Lepeophtheirus
