Dynamic Interfacial Modulation in Pt@Ga Liquid Metal Systems

open access: yesAdvanced Science, EarlyView.
This work introduces a facile dissolution‐reconstruction approach to prepare the Pt@Ga liquid catalyst by dissolving Pt in molten Ga and then using electrochemical treatment to reconstruct Pt on the Ga support, which provides a new design strategy for liquid‐metal catalysts and enhances the understanding of oxide‐modulated segregation, offering new ...

Lithium Squarate as Sacrificing Electrolyte Additive for Prelithiation: Case Study in Zero‐Excess Lithium Metal Batteries

open access: yesAdvanced Science, EarlyView.
Active lithium loss (ALL) and capacity fade can be compensated by prelithiation, apparently simple via sacrificing additives e.g., lithium squarates. However, as a cathode additive it ruptures the cathode via gas evolution, while as an electrolyte additive it gets reductively depleted on anode side in course of solid electrolyte interphase (SEI ...

All‐Hydrogel‐Based Organic Electrochemical Transistors for Implantable Physiological Signal Monitoring

open access: yesAdvanced Science, EarlyView.
All‐hydrogel based n‐type depletion‐mode OECTs is developed using a semiconductor hydrogel formed via ionic‐liquid‐mediated phase separation, combining efficient ion‐electron transport, tissue‐like softness, and long‐term biocompatibility. The device can monitor EOG and ECG on human skin and record real‐time ECG subcutaneously in rats, providing a ...

Transparent Transfer‐Free Ultrasmall Multilayer Graphene Microelectrodes Enable High Quality Recordings in Brain Slices

open access: yesAdvanced Science, EarlyView.
A transfer‐free fabrication method enables multilayer graphene microelectrodes as small as 10 µm, eliminating reliability issues of manual graphene transfer. These electrodes record neural activity in brain slices with exceptional signal‐to‐noise ratios (up to 25–40 dB) while maintaining optical transparency for multimodal applications.

Durable Thin‐Film Porous Transport Electrodes for High Current Density PEM Water Electrolysis

open access: yesAdvanced Science, EarlyView.
Water electrolysis using porous transport electrodes with sputter‐deposited, ionomer‐free thin films of rutile IrO2 catalyst suppresses Ir dissolution by >10x over other forms of IrOx. The rutile IrO2 catalyst prepared by this readily scalable electrode synthesis method provides stable cell operation at 3 A cm−2 while using low Ir loading (0.4 mg Ir cm−

Dissolution Study of Biodegradable Magnesium Silicide Thin Films for Transient Electronic Applications

open access: yesAdvanced Science, EarlyView.
Magnesium silicide (Mg2Si) is introduced as a narrow‐bandgap, biodegradable semiconductor for transient electronics. RF‐sputtered and annealed Mg2Si thin films show high intrinsic electrical conductivity and low thermal conductivity. The polycrystalline material undergoes hydrolysis in aquatic and composting environments with minimal cytotoxicity ...
