Redirecting Nano‐Silicon Agglomeration: Dual‐Carbon Design Triggers Self‐Adaptive Nanoporous Si Sponge for Enhanced Lithium Storage

open access: yesAdvanced Functional Materials, EarlyView.
This study addresses silicon anode degradation using an engineered nSi/Gr/C dual‐carbon matrix. By restricting SEI infiltration, the architecture redirects silicon agglomeration into a beneficial structural self‐adaptive activation. During cycling, silicon nanoparticles self‐organize into a resilient nanoporous sponge. This dynamic network accommodates

An In Situ Oxidation Strategy for Ti3C2@TiO2 Heterojunction: Narrow‐Band Photodetection and Trace Chromium Ion Determination

open access: yesAdvanced Functional Materials, EarlyView.
A Ti3C2@TiO2 heterostructure has been successfully fabricated by an in situ oxidation approach. The as‐fabricated Ti3C2@TiO2‐based photodetector exhibits narrow‐spectrum response with excellent stability. It also realizes sensitive Cr(VI) detection in a large concentration range of 10−12–10−6 M with an ultra‐low detection limit of 7.6 × 10−12 M ...
