3D Concrete Printing of Triply Periodic Minimum Surfaces for Enhanced Carbon Capture and Storage

Advanced Functional Materials, EarlyView.
A 3D‐printable and carbon‐capturing concrete is developed by replacing cement with diatomaceous earth (DE), which enhances rheology, provides hierarchical porosity, and serves as a nucleation site for carbonation. Maximum absorption of 488.7 gCO2 kgcement−1 is achieved in 7 days, a 142% increase over conventional concrete, and the triply periodic ...

Mimicking Synaptic Plasticity: Optoionic MoS2 Memory Powered by Biopolymer Hydrogels as a Dynamic Cations Reservoir

Advanced Functional Materials, EarlyView.
Janus (MoS2) transistors functionalized with sodium alginate (SA) and poly(vinylidene fluoride‐co‐trifluoroethylene) [P(VDF‐TrFE)] exhibit persistent photo‐induced ionic gating, driven by dynamic cation migration at the hybrid interface. This ionic mechanism enables finely tunable photoconductivity and emulates key synaptic plasticity behaviors ...

Polymer‐Incorporated Mechanically Compliant Carbon Nanotube Microelectrode Arrays for Multichannel Neural Signal Recording

Advanced Functional Materials, EarlyView.
This work presents a soft microelectrode array based on vertically aligned carbon nanotube (CNT) forests, combining high conductivity with mechanical softness. A densification process and air‐pressure‐assisted flexibilization improve structural integrity, ensuring stable insertion and reduced inflammation.

Mechanisms of Anode Interfacial Phenomena and Multi‐perspective Optimization in Aqueous Alkaline Zinc‐Air Batteries

Advanced Functional Materials, EarlyView.
Zinc‐air batteries demonstrate great potential for sustainable energy storage but face major anode‐related challenges. This review provides a mechanism‐driven overview of zinc anode interfacial issues, e.g. dendrite formation, passivation, self‐corrosion, and hydrogen evolution; and explores advances in electrode, surface, and electrolyte engineering ...
