Utilization of cellulose nanocrystal as a bio‐based material and nanosilica in cement‐based systems: A comparative study

open access: yesStructural Concrete, EarlyView.
Abstract Cellulose nanocrystals (CNCs), increasingly utilized in cement‐bound materials, offer improved material properties and enhanced sustainability due to their bio‐based origin. Nanosilica (NS), known for its high reactivity and refinement of cement microstructure, also significantly impacts cement performance.

Cabomba caroliniana and Schoenoplectus californicus as Antifouling Candidates: Anti‐Attachment and Toxicological Effects in Aurelia coerulea (Cnidaria, Scyphozoa)

open access: yesEnvironmental Toxicology, EarlyView.
ABSTRACT Biofouling on artificial surfaces in aquatic ecosystems leads to significant economic losses. Current antifouling paints, while effective, often harm the aquatic environment. This study explores ecologically safe antifouling alternatives derived from plants, focusing on the aquatic macrophytes Cabomba caroliniana (CC) and Schoenoplectus ...

Feeding Management of African Rhinos (Ceratotherium simum, Diceros bicornis) in European Zoos

open access: yesZoo Biology, EarlyView.
The average estimated diets (in % dry matter) of white rhinos (C. simum) and black rhinos (D. bicornis) in European zoos differ in the proportion of (pelleted) compound feed and other non‐forage items. The reason for this difference is elusive but possibly related to creating more complicated diets for browsers. ABSTRACT White rhinos (WR, Ceratotherium
