Self‐Assembled Conjugated Hollow Fibers for Spongy Monoliths Toward Solar‐Driven Desalination and Hydrovoltaic Electricity Generation

Small, EarlyView.
A self‐assembled conjugated hollow fiber monolith enables simultaneous solar‐driven desalination and hydrovoltaic electricity generation. Metal‐free polymerization produces cross‐linked hollow fibers that entangle into a porous monolith, followed by gradient polypyrrole coating for efficient light absorption and directional water transport.

Modeling Skin Mark Temporal Variations to Estimate the Sex of Delphinids with Low Sexual Dimorphism: Implications for Management and Conservation

Integrative Zoology, EarlyView.
This work aimed to apply the principles of skin mark analysis to a cetacean species to build a sex‐discrimination model exclusively based on photographic material. Relevant differences between sexes emerged in markings, with males presenting more social, aggression‐related, and fishing‐related marks overall, and a stronger tendency of mark accumulation
