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 ...

Decoupling Light Absorption From Photocatalytic Reactivity in TiO2 via Defect and Interfacial Engineering

Advanced Functional Materials, EarlyView.
A hybrid photoprotective material integrates N‐doped TiO2 with a metal‐phenolic network (MPN) to achieve broad‐spectrum attenuation and robust reactive oxygen species (ROS) suppression. Nitrogen doping extends attenuation into the UVA/high energy visible light (HEV) regions and facilitates fast charge recombination to inhibit ROS formation.

The fault detection and severity diagnosis of rolling element bearings using modulation signal bispectrum

The rolling element bearing is a key part in many mechanical equipment. The accurate and timely diagnosis of its faults is critcal for predictive maintenance. Vibration signals from a defective bearing with a localized fault contain a series of impulsive

Three‐Dimensional Biomimetic Aerogel Conduits with Electro‐Ionic‐Immune Coupling Reverse the Pathological Cascade of Spinal Cord Injury

Advanced Functional Materials, EarlyView.
A biomimetic aerogel conduit was engineered from a nanofiber of gelatin/poly(l‐lactic acid) doped with polypyrrole nanoparticles, integrated with tannic acid and Mg2+. This “electro‐ionic‐immune” strategy mimicked spinal cord properties, reduced calcium overload, inflammation, oxidative damage, promoted neural stem cell differentiation, suppressed ...
