Bioinspired Bromination Enables Extensible, Strain‐Stiffening Resilin Peptide Scaffolds with Tunable Degradation

Advanced Functional Materials, EarlyView.
Bioinspired bromination of a resilin‐derived peptide enables the fabrication of electrospun nanofibrous scaffolds that uniquely combine strain‐stiffening elasticity, proteolytic stability, and antioxidant functionality. These brominated peptide–gelatin hybrids mimic the extensibility of natural elastomers, demonstrating tunable mechanical resilience ...

Solar Heating Enhanced Selective Recovery of Metal Ions Through Flowing Electrodes Enabled by Hybrid Carbon Nanostructures

Advanced Functional Materials, EarlyView.
A new electrochemical system based on a microporous hybrid of carbon nanoplatelets and nanotubes to selectively capture Ni2+ from wastewater is constructed. The system temperature rises rapidly when irradiated with sunlight, which enhances the Ni2+ removal rate by 250% and the selectivity by 53%, and the energy consumption is also reduced by 51 ...
