High-temperature thin-film sensors (HTTSs) offer promising solutions for in situ monitoring of various thermal and mechanical parameters in extreme environments. However, maintaining their stable operation at high temperatures exceeding 1000 °C for extended durations remains challenging due to severe material degradation. This study first demonstrates a microstructural engineering strategy to enhance the thermal endurance of metal oxide thin films through integrating high-melting-point metal oxide nanophases. Using standard Micro-Electro-Mechanical System (MEMS) technologies, alumina (AlO) is atomically integrated into indium tin oxide (ITO) thin films. The influence of AlO doping on the ITO matrix under various high-temperature conditions, with emphasis on the variations of chemical composition, crystal structure, morphology, recrystallization, and sensing behavior, is systematically investigated. An optimized film, characterized by an Al/In ratio of 1.57 wt.%, exhibits a record-low resistance drift of 0.002% h during a 10 h exposure at 1200 °C.

The sensitive, efficient, and simultaneous assay of creatinine and urea in different body fluid is crucial for the daily detection and treatment of chronic kidney disease. Here, we exploited a versatile composite surface enhanced Raman scattering (SERS) substrate of polydimethylsiloxane (PDMS)-flower-like ZIF-67@Ag nanoparticles (NPs) based on simple in-situ growth and ion sputtering strategies. The plasmonic Ag NPs assembled on the three-dimensional anisotropic ZIF-67 matrix, facilitating numerous resonant electromagnetic "hotspots".

Methods for electrochemical detection of heavy metal ions have garnered widespread attention due to their high sensitivity, ease of operation, low cost, and suitability for on-site detection. However, these methods typically require a pre-enrichment step to improve the detection limit and sensitivity, which increases operational complexity and introduces potential errors. In this study, tungsten oxide electrodes with various functional groups were prepared by electrodeposition and high-temperature annealing, utilizing the amphoteric properties of l-alanine.
