Representation of obligate groundwater‐dwelling copepod diversity in European protected areas
Conservation Biology, Volume 40, Issue 3, June 2026.Abstract Groundwaters sustain diverse surface ecosystems and are populated by metazoan species, mostly invertebrates, that provide fundamental ecological functions and are often of prominent conservation value due to narrow endemism and high phylogenetic rarity.

Rare Metals, Volume 45, Issue 5, May 2026.ABSTRACT Recovering palladium (Pd) from low‐concentration metallurgical wastewater still poses significant challenges. In this study, triaminoguanidine hydrochloride was used as the key functional site, and three guanidine‐functionalized covalent organic frameworks (GCOFs) were successfully constructed by adjusting the substituents (–H, –OH, and –OCH3)

Rare Metals, Volume 45, Issue 5, May 2026.ABSTRACT The residue of mesotrione poses an increasingly serious threat to the environment and human health. Thus, it is essential to establish a platform that integrates rapid detection and efficient degradation. Covalent organic frameworks (COFs) materials have garnered significant attention owing to their designability.
