Correlating activities and defects in (photo)electrocatalysts using in-situ multi-modal microscopic imaging

Physicochemical heterogeneity poses a significant constraint in photocatalyst advancement. Here the authors introduce a multimodal optical microscopy platform to assess activity and defects concurrently in photoelectrocatalysts, revealing that disorder can unexpectedly enhance local photoelectrocatalytic performance in certain instances.

Pheomelanin pigment remnants mapped in fossils of an extinct mammal

Chemical imaging and spectroscopy have previously been used to identify eumelanin residue in fossils and infer dark coloration. Here, Manning and colleagues develop an approach to identify pheomelanin (red pigment) residues and ascertain their distribution in fossils.

Deep anoxic aquifers could act as sinks for uranium through microbial-assisted mineral trapping

Reduction of geochemically mobile hexavalent uranium in deep anoxic aquifers is facilitated by bacteria-driven degradation of organic material and accumulation in calcite and iron-sulfides, according to observations and experiments from a borehole at Äspö, Sweden.
