Electrically Assisted Thermal Stamping of Tunable Carbon‐Based Nanofilms for Direct Fabrication of Hydrophobic, Energy Harvesting, and Sensing Devices

open access: yesAdvanced Materials, EarlyView.
Schematic illustration of the electrically assisted thermal stamping (EATS) method for direct fabrication of carbon‐based nanofilms and their multifunctional applications. Localized Joule heating triggers simultaneous exfoliation, reduction, and fluoropolymer incorporation under ambient conditions, yielding tunable carbon‐based thin‐film coatings ...

Ammonium Salts as Curing Agents to Obtain Ionic Epoxy Resins With a Thermoplastic‐to‐Thermoset Transition

open access: yesAdvanced Materials, EarlyView.
Ionic epoxy networks are prepared using ammonium salts as hardeners, leading to a two‐stage curing process with a thermoplastic‐like intermediate. This uncommon behavior enables extrusion and fabrication of thermoplastic prepregs that can be cured into thermoset composites.

An Energy Focusing Flexible and Lightweight Acoustic Metamaterial for Enhanced Ultrasound Power Transfer

open access: yesAdvanced Materials, EarlyView.
A flexible and lightweight acoustic metamaterial composed of air cavities encased in polydimethylsiloxane (PDMS) is introduced to enhance ultrasound power transfer. The metamaterial leverages the strong reflectivity of air cavity boundaries to concentrate incoming ultrasound, thereby improving the performance of piezoelectric energy harvesters ...

Bulk and Surface Dual‐Modification for Stabilizing RuO2 Anode in 2 A cm−2 PEMWE Operation

open access: yesAdvanced Materials, EarlyView.
The high‐current‐density stability of the RuO2‐based anode in PEMWE could be taken care of by a bulk and surface dual modification strategy developed in this work, where Cr doping modulates the Ru valence state in the bulk phase, suppressing Ru overoxidation, whereas Si modification stabilizes the reaction interface by inhibiting catalyst ...

Stoichiometry‐Programmed MXenes via Precursor Engineering for High‐Performance EMI Shielding and Energy Storage

open access: yesAdvanced Materials, EarlyView.
Precursor carbon stoichiometry programs internal strain and oxygen substitution in Ti3AlCxO2‐x, deterministically switching Ti3CxO2‐xTz MXenes between highly aligned 2D nanosheets and spontaneous 1D nanoscrolls. This synthesis‐stage architecture control enables ultrathin X/W‐band EMI shielding with outstanding mass‐normalized performance and bending ...

Decoding High‐voltage LiCoO2: From Degradation to Stabilization Toward Durable Li‐ion Batteries

open access: yesAdvanced Materials, EarlyView.
This review systematically addresses the degradation mechanisms and stabilization strategies for high‐voltage LiCoO2 cathodes. Key enhancement approaches including foreign‐ion doping, surface modifications, structural design, and electrolyte optimization are critically assessed.
