The unique electron/ion dual regulation mechanism is established in the well-designed hydrogel electrolyte by integrating polyacrylamide network and carboxylated multi-walled carbon nanotubes for high performance flexible ZIBs.

Lignin, a natural amorphous three-dimensional aromatic polymer, is investigated as an appropriate filler for biocomposites. The chemical modification of firsthand lignin is an effective pathway to accomplish acetoacetate functional groups replacing polar hydroxyl (–OH) groups, which capacitates lignin to possess better miscibility with poly(lactic acid) (PLA), compared with acidified lignin (Ac-lignin) and butyric lignin (By-lignin), for the sake of blending with poly(lactic acid) (PLA) to constitute a new biopolymer based composites. Generally speaking, the characterization of all PLA composites has been performed taking advantage of Fourier transform infrared (FTIR), scanning electron microscopy (SEM), dynamic Mechanical analysis (DMA), differential scanning calorimeter (DSC), thermogravimetric analysis (TGA), rheological analysis, and tensile test. Visibly, it is significant to highlight that the existence of acetoacetate functional groups enhances the miscibility, interfacial compatibility, and interface interaction between acetoacetate lignin (At-lignin) and PLA. Identical conclusions were obtained in this study where PLA/At-lignin biocomposites furthest maintain the tensile strength of pure PLA.

Full biobased, water soluble and low cell cytotoxicity cellulose levulinate esters were prepared via the reaction of cellulose with α-AL, and CLE film has a tensile strength up to 72 MPa and an elongation at break up to 26.7%.

Crystalline nitrogen-doped-carbon anchored Fe₃O₄ nanoparticles were synthesized through the pyrolysis of a mixture of g-C₃N₄ and Fe@Tpy, which promoted scalable and affordable neutral H₂O₂ electrosynthesis under H₂O (salt-free) and O₂ condition.
