Article Abstract

Wearable healthcare devices have garnered substantial interest for the realization of personal health management by monitoring the physiological parameters of individuals. Attaining the integrity between the devices and the biological interfaces is one of the greatest challenges to achieving high-quality body information in dynamic conditions. Liquid metals, which exist in the liquid phase at room temperatures, are advanced intensively as conductors for deformable devices because of their excellent stretchability and self-healing ability. The unique surface chemistry of liquid metals allows the development of various sensors and devices in wearable form. Also, the biocompatibility of liquid metals, which is verified through numerous biomedical applications, holds immense potential in uses on the surface and inside of a living body. Here, the recent progress of liquid metal-based wearable electronic devices for healthcare with respect to the featured properties and the processing technologies is discussed. Representative examples of applications such as biosensors, neural interfaces, and a soft interconnection for devices are reviewed. The current challenges and prospects for further development are also discussed, and the future directions of advances in the latest research are explored.

Engineering Brønsted Acidic Microenvironments via Strong Metal-Support Interaction in Single-Atom Pd/CeO for Acid-Free Acetalization Catalysis.

Inorg Chem

Conventional acid-catalyzed acetalization faces significant challenges in catalyst recovery and poses environmental concerns. Herein, we develop a CeO-supported Pd single-atom catalyst (Pd/CeO) that eliminates the reliance on liquid acids by creating a localized H-rich microenvironment through heterolytic H activation. X-ray absorption near-edge structure and extended X-ray absorption fine structure analyses confirm the atomic dispersion of Pd via Pd-O-Ce coordination, while density functional theory (DFT) calculations reveal strong metal-support interactions (SMSI) that facilitate electron transfer from CeO oxygen to Pd, downshifting the Pd d-band center and optimizing H activation.

LiNiMnO (LNMO) is a promising material for the cathode of lithium-ion batteries (LiBs); however, its high operating voltage causes stability issues when used with carbonate battery electrolytes. Ionic liquids are a viable alternative to conventional carbonate solvents due to their thermal stability and electrochemical window. This work reports the performance of LNMO/Li half cells with an ionic liquid electrolyte (ILE) composed of 0.

Electric droplet sorting is widely applied in the screening of target molecules, cells, drugs, and microparticles. Previous studies have made several optimizations on the electrode materials, structures, and arrangements. However, voltages of over 1 kV are required to realize droplet sorting, which causes the undesired droplet splitting.

Hydridoborate-Based Solid Electrolytes for All-Solid-State Batteries.

Adv Mater

September 2025

College of Smart Materials and Future Energy, Fudan University, Shanghai, 200433, P. R. China.

All-solid-state batteries (ASSBs) utilizing solid electrolytes, which replace flammable liquid electrolytes, are regarded as one of the most promising prospective energy storage devices due to their inherent safety advantages and high energy density potential. As an emerging class of electrolytes for ASSBs, hydridoborates have attracted research interest because of their attractive material properties, including superior compatibility with metal anodes, low gravimetric density, and excellent solution processability. In this review, hydridoborate-based solid electrolytes (SEs) for all-solid-state batteries, including boranuide-based SEs, arachno-hydridoborate-based SEs, nido-hydridoborate-based SEs, closo-hydridoborate-based SEs, and conjuncto-hydridoborate-based SEs, are comprehensively summarized.
