Ceria Nanostructures Obtained by Hydrothermal Synthesis: Exploring the Experimental Parameter Landscape for Precise Morphology and Size Control

Many oxidation catalysts rely on ceria nanomaterials as efficient supports for platinum group metal nanoparticles, where morphology affects the catalytic performance. Rational exploitation of the chemical parameter space enables the tuning and control of these morphological features. This study presents a systematic investigation of conventional and microwave-assisted hydrothermal syntheses of ceria nanorods and nanocubes. The specific role of Ce(III) counter-ions in nanorod formation was ...

Heterogeneity in otolith microchemistry composition suggests multiple natal origins of Antarctic silverfish (Pleuragramma antarcticum) in the Ross Sea

The Antarctic silverfish (Pleuragramma antarcticum) is a key species in the Southern Ocean ecosystem, playing a crucial role in energy transfer between lower and higher trophic levels. Its early life stages are potentially threatened by climate change, and therefore, assessing natal origins and larval connectivity can be crucial for planning management strategies for this species. However, studies investigating population structure and connectivity are still extremely limited. Using Laser Abl...

SCARFISH: A new SCAR action group to co-ordinate Antarctic fish research

Mapping the footprint of untracked small-scale fisheries using multicriteria spatial analysis and optical satellite imagery

The effective monitoring of small-scale fisheries footprint is critical for fisheries management and marine conservation. Yet, this remains challenging due to limited vessel tracking requirements for small boats under 12 m. This study presents the first attempt to combine Multi-Criteria Spatial Analysis (MCSA) and Sentinel-2 remote sensing approaches for mapping small-scale fisheries (SSF) footprint, using Sicily as a case study. The MCSA combined a habitat suitability index, informed by inte...
