High‐Precision Multiplex Chemical Sensors with Pattern‐Recognition Capability via a Letter Printing‐Inspired Transfer Method

ABSTRACT Graphene‐based chemical sensors offer high sensitivity owing to exceptional charge transport and a large surface‐to‐volume ratio, yet reliable discrimination across diverse analytes remains challenging. In this study, a letterpress‐inspired, one‐step transfer‐printing st...

Spatially Regulated Silicon Clusters in Trimodal Composite Anodes for High‐Energy Lithium‐Ion Batteries

ABSTRACT Fast‐charging, high‐energy lithium‐ion batteries are central to electrified transportation and grid‐scale energy storage, but their advancement is limited by the instability of high‐capacity anode materials such as silicon (Si). Although graphite (G)‐Si composites offer...
