Harnessing Chain Mobility via Protonation for Tough and Isotropic Hydrogel

Advanced Materials, Volume 38, Issue 16, 17 March 2026.
A protonation‐guided strategy enables ultra‐tough, isotropic PVA hydrogels by temporarily unlocking chain mobility via acidification and fixing homogeneous networks through salting‐out. The resulting materials simultaneously achieve high strength, extreme stretchability, and record‐level toughness, offering a generalizable route toward robust hydrogels

Response of soil characteristics and N2O emissions to fertilizer reduction strategies in highland summer vegetable production

Agrosystems, Geosciences &Environment, Volume 9, Issue 1, March 2026.
Abstract In recent years, the escalating application of nitrogen fertilizers in global vegetable production has positioned vegetable fields as significant sources of nitrous oxide (N2O) emissions, eliciting widespread environmental concern. However, the interrelationships among fertilizer reduction gradients, soil physicochemical properties, microbial ...

Hydroxyapatite dissolution kinetics: The effects of molecular configurations of six carboxylic acids

Soil Science Society of America Journal, Volume 90, Issue 2, March/April 2026.
Abstract Phosphorus (P) availability in calcareous soils is limited by the low solubility of calcium phosphate minerals, such as hydroxyapatite (HAP). Carboxylic acid‐promoted dissolution of HAP is well‐known. However, it is not clearly understood how the composition and orientation of functional groups (e.g., carboxyl and β‐hydroxyl group) in ...

Characterization of Co(II)-PAMAM dendrimer complexes with polypropylene oxide core by using UV-VIS spectroscopy

Macedonian Journal of Chemistry and Chemical Engineering, 2016
The aim of this study was to characterize poly(amidoamine) (PAMAM) dendrimer complexes of Co(II) ions by using UV-Vis spectroscopy. For this aim, a generation-4 polypropylene oxide (Jeffamine® T-403) cored and amine-terminated PAMAM dendrimer (P4) was ...

Controllable Modulation of Interactive Site Spacing in Porous Coordination Cages: A Key to Substantial Synergistic Catalysis Enhancement

Small Structures, Volume 7, Issue 3, March 2026.
This work presents a ligand‐engineering strategy to controllable program the spatial proximity between Brønsted acidic (μ4–H2O) and basic (–NH2) sites within isostructural calixarene‐based Co4 cages. Reducing the intersite distance from 12.4 Å to 5.6 Å leads to a nonlinear surge in Knoevenagel condensation activity.

Fenton Treatment of Filter Backwash Water for Recycling in DWTP

Water Environment Research, Volume 98, Issue 3, March 2026.
The graphical abstract illustrates the treatment and recycling pathway of filter backwash water (FBW) generated in drinking water treatment plants. The proposed treatment innovatively applies the Fenton advanced oxidation process, using the iron naturally present in the FBW, with a sedimentation step for effective clarification. ABSTRACT Drinking water
