Mechanochemical and Aging‐Based SN2 Method to Access CO2‐Responsive, High‐Amine‐Loading Chitosan

open access: yesChemSusChem, EarlyView.
We report a green, scalable mechanochemical SN2 method to synthesize CO2‐responsive chitosan with a record‐high amine loading (DS up to 1.67). This one‐pot process functionalizes both amine and alcohol groups using minimal reagents and energy. The resulting biopolymer exhibits reversible pH and osmotic pressure changes upon CO2 exposure, offering a ...

Mechanochemical‐Assisted Defect Engineering: Enhanced Post‐Synthetic Metal Exchange in MOFs

open access: yesEcoEnergy, EarlyView.
The application of mechanochemical‐assisted defect engineering serves to augment the post‐synthesis metal exchange process of metal–organic frameworks (MOFs). This strategic approach facilitates the successful construction of heterometallic MOFs.

A Novel Strategy for Preparing High‐Entropy Ceramics Through Full Glass Crystallization

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
This study focuses on an innovative strategy for preparing high‐entropy ceramics applicable in extreme environmental protection and related fields. The high‐entropy (Eu0.2Gd0.2Y0.2Yb0.2Lu0.2)3Al5O12 samples prepared by the low‐temperature glass crystallization method exhibit a low thermal conductivity (3.58 W m−1 K−1), high thermal expansion (10.85 ...

Interfacial Engineering of Fe–Zr Bimetallic Oxides Boosts Phenolic Pollutants Removal in Heterogeneous Fenton–Like Process

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
The interfacial synergy at Fe–Zr heterojunctions facilitated HO˙ formation, which triggered the dimerization of surface‐adsorbed BPA by abstracting phenolic hydrogen and forming C–C bonds between adjacent molecules. Fenton technology has garnered significant attention for the deep removal of low‐concentration emerging contaminants due to its remarkable
