Increasing Inter‐Micellar Connectivity Toughens and Imparts Cooling‐Induced Shape Memory in Micellar Hydrogels

Advanced Functional Materials, EarlyView.
Oligomerizing Pluronic triblock copolymers provides a processing strategy for tuning the mechanical properties and stimuli‐responsive behaviors of micellar hydrogels. Varying oligomer fraction produces hydrogels spanning brittle to highly extensible responses; maintaining micellar architectures enables cooling‐induced reverse thermal shape memory and ...

Effects of Interaction between Humic Acid and Birnessite on Antimony Speciation in Yellow Soil from Antimony Mining Areas

Yankuang ceshi
Antimony (Sb) contamination in mining area soils is severe, and its environmental risk mainly depends on the chemical speciation of Sb. Mn oxides and humic acids are key active components that regulate Sb speciation in soil.

Mitigating Concentration Polarization in Dry‐Processed Ultra‐Thick Cathodes Using a Low‐Viscosity Electrolyte With Soft Li+ Solvation

Advanced Functional Materials, EarlyView.
A low‐viscosity, soft‐solvating methyl ethanoate (ME)‐based electrolyte facilitates electrolyte infiltration into dense dry‐processed ultra‐thick NCM622 cathodes while reducing Li+ desolvation barriers at Li‐metal anodes. Balanced cathode‐scale ion transport and anode‐side interfacial kinetics mitigate concentration polarization and interfacial ...
