Abstract Methane (CH 4 ) serves as a commonly utilized fuel gas in various industrial and everyday settings. Given its flammable, explosive, greenhouse nature, the real‐time monitoring of concentration air holds vital importance across practical applications. The tetrahedral structure methane molecules features high bond energies, posing significant challenge for chemical detection over metal oxide‐sensitive layers. In this research, multicomponent assembly method is used to synthesize ordered mesoporous tin oxide (SnO 2 with uniform large mesopores (≈ 10 nm) pore wall functionalized Pd x Pt nanoalloys 2.5 nm), due unusual C–H activation capabilities semiconducting properties SnO , obtained Pt@m‐SnO fabricate sensors which showcases wide applicability range detecting concentrations ranging from 50 20 000 ppm at 400 °C, it yields substantial CH response 9.19 (1000 ppm) an ultralow limit value 175.9 ppb. Furthermore, sensor successfully incorporated into portable device, evidencing capability accurate real‐world scenarios.

Rapid and sensitive detection of 2-ethylhexanol vapor, a critical indicator overheating in electrical cables, is essential for the early warning potential fires. However, traditional chemiresistive gas sensors are inadequate real-time owing to its chemical stability. Herein, sensor based on mesoporous Nd-doped In2O3 designed rapid ppb-level vapor. The exhibits high response (22.8@1 ppm), excellent sensitivity (4.7 ppm–1), short time (29 s), low limit (760 ppb). After Nd doping, approximately 20 folds higher than that sensor. Furthermore, wireless sensing device has been developed enable monitoring cable overheating. outstanding performance can be attributed neodymium doping within framework, which enhances accessibility active sites interface materials, increases concentration surface-adsorbed oxygen at gas–solid interface, improves adsorption capacity 2-ethylhexanol. This work showcases an efficient semiconductor metal oxide capable rapidly sensitively detecting parts per billion levels induced by demonstrating significant

The complicated environment of the oral cavity presents significant challenges to traditional antibacterial approaches, which has driven exploration novel therapeutic strategies. Metal-based nanomaterials (MNMs), with diverse mechanisms (e.g., membrane disruption, oxidative stress) and evolution from empirical theory-guided design, exhibit immense potential. This review introduces pioneering Hierarchical Response Strategy Framework, systematically classifying MNM systems into three progressive levels: Primary category, comprising MNMs that exert spontaneous effects based on inherent physicochemical properties ion release); Secondary including precisely controlled actions by microenvironmental or stimulus-responsive light-induced ROS); Tertiary encompassing integrate regenerative functions for multidimensional therapy remineralization). Through this framework, authors elucidate MNMs' transition single-function precision-controlled, multifunctional synergy, analyze impact metal elements structural design efficacy, summarize their applications in dental caries, endodontic infections, periodontal disease, etc. framework offers a perspective existing research theoretical foundation rational next-generation precise, smart, comprehensive anti-infective materials.

Abstract Conventional gas sensing materials (e.g., metal oxides) suffer from deficient sensitivity and serve cross-sensitivity issues due to the lack of efficient adsorption sites. Herein, heteroatom atomically doping strategy is demonstrated significantly enhance performance oxides-based materials. Specifically, Sn atoms were incorporated into porous Fe 2 O 3 in form dispersed As revealed by X-ray absorption spectroscopy atomic-resolution scanning transmission electron microscopy, these successfully occupy sites lattice, forming unique Sn–O–Fe Compared Fe–O–Fe (from bare ) Sn–O–Sn SnO /Fe with high loading), on exhibit a superior ( R g / = 2646.6) 1 ppm NO , along dramatically increased selectivity ultra-low limits detection (10 ppb). Further theoretical calculations suggest that strong (N atom site, site) contributes more response, compared other gases Moreover, reduce bandgap not only facilitating release but also increasing at low working temperature (150 °C). This work introduces an effective construct show response specific molecules, potentially promoting rational design modified selectivity.
