Photogeneration of Hydrogen in Water via Self‐Assembly‐Induced Colloidal Covalent Organic Framework Particles

open access: yesSmall Science, EarlyView.
A surfactant‐free strategy using a functional Poly(DiMethylAminoEthylMethAcrylate) polybase enables stable colloidal imine‐linked COFs formation via self‐assembly‐induced process. A dual effect is demonstrated with the control in size and stabilization in colloidal state of the COFs in situ synthesized.

Phylogeny, species delimitation and machine learning bridge the gap between DNA sequences and morphology in the lichen genus Arctomia (Arctomiaceae, Ascomycota)

open access: yesTAXON, EarlyView.
Abstract This study investigates species boundaries in the lichen genus Arctomia (Arctomiaceae, Ascomycota) using an integrative approach combining molecular phylogenetics, full Bayesian population delimitation, heuristic and model‐based species delimitation, and supervised machine learning applied to morphological data.

Media‐Dependent Growth, Stress Responses, and Metal Accumulation Patterns in Azolla imbricata (Roxb.) Nakai Exposed to As, Cd, Cu, Pb, and Zn: Individual and Combination Effects (Synergistic, Antagonistic, and Additive)

open access: yesEnvironmental Toxicology, EarlyView.
ABSTRACT In this study, we examined metal accumulation and biochemical responses of Azolla imbricata (Roxb.) Nakai exposed to water medium (WM) and nutrient medium (NM) under single and combined (co‐exposure) treatments with five metals (As, Cd, Cu, Pb, and Zn) at 10% environmentally relevant concentrations.
