Journal 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

Spin‐State Modulation of Atomic Iron Sites Enables Efficient CO2 Electroreduction in Acid Medium
Angewandte Chemie, Volume 138, Issue 20, 11 May 2026.An axial oxygen ligand was added to shift the spin state of the single‐atom Fe site from low to medium spin. This change reduces the interfacial interaction with H3O+ and decreases the *CO desorption energy, thus enhancing CO2RR in acidic media.
