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

Advanced 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

Synthesis of AgBiS2 and AgInS2 Based on Formation Energies in Sulfur‐Rich Reducing Flame

Advanced Functional Materials, EarlyView.
High‐surface‐area AgInS2 and AgBiS2 nanoparticles were synthesized via enclosed flame spray pyrolysis by tuning flame conditions and formation energies to guide phase formation. Flame parameters were tuned to suppress oxides and enable pure sulfide phase growth.

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

Advanced 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 ...
