A Biologically‐Architected Wear and Damage‐Resistant Nanoparticle Coating From the Radular Teeth of Cryptochiton stelleri

open access: yesAdvanced Functional Materials, EarlyView.
The ultrahard teeth of mollusks that feed on rocky substrates contain a wear‐resistant coating on their surfaces consisting of densely packed mesocrystalline magnetic nanoparticles within an organic matrix. These coatings display significant hardness and toughness through their highly controlled mesocrystalline architectures.

Wetting Interactions Between Porous Carbon Hosts and Liquid Sodium‐Potassium Alloys Toward Their Use in Negative Electrodes of Alkali‐Metal Batteries

open access: yesAdvanced Functional Materials, EarlyView.
Porous carbon host materials are investigated for their possible usage in liquid alkali‐metal negative electrodes. X‐ray computed tomography reveals pore‐filling behavior under various conditions: non‐wetting, forced wetting, and spontaneous wetting. The applicability of porous carbon in electrochemical cells is demonstrated at high areal capacities ...

Fluoride‐Free Adhesives for Low Surface Energy Fluorinated Substrates

open access: yesAdvanced Functional Materials, EarlyView.
A universal, fluoride‐free adhesive achieves a record 4.91 MPa bond strength on PTFE by leveraging amine/amide dipole–dipole interactions, without fluorinated components. This sustainable strategy overcomes the environmental and performance limits of PFAS‐based adhesives, enabling robust, eco‐conscious bonding across diverse materials.
