Summary: A Pd-Ni film hydrogen sensor with high hydrogen response and selectivity was prepared by coating a 1.3 pm-thick organosilica membrane on the surface of the Pd-Ni alloy film. The gas sensing performance of the sensor was tested and showed improved response in both N2 and air atmosphere. The presence of oxygen did not affect the response of the sensor to hydrogen, although the response/recovery time increased. The mechanism of response and selectivity enhancement was explored.

Summary: Constructing a heterojunction of hierarchical and porous NiO/TiO2 layers is effective for improving gas sensing properties. The hydrogen sensor designed in this study consists of NiO nanowalls with exposed (111) facets on top and (002) oriented TiO2 nanorod arrays at the bottom. The heterojunction-induced high energy crystal surfaces and surface depletion region enable the sensor to have a wide detection range and a higher response to hydrogen. The optimized size of the pores between the walls provides excellent interference prevention from CO.

Summary: The high concentration of ammonia in exhaled breath can be a biomarker for end-stage renal disease, but detecting it using gas sensors is challenging due to the complex components and high humidity of the gases. A new NH3 sensing design using a humidity-activated mechanism at room temperature was developed, with promising results for highly selective detection of NH3 under high humidity conditions. The environmentally friendly biomass hydrogel sensor showed a strong response to 50 ppm NH3 at 80% relative humidity, suggesting its potential for analyzing exhaled breath.

Summary: In this article, we report a novel miniature gas sensor with a high selectivity for H2S detection. The sensor is based on the principle of silver reacting with H2S at high temperature. It has a limit of detection of 1.4 ppm in ambient conditions, and can be further reduced to similar to ppb-level by improving the working temperature and suppressing sensor system noise. Compared with conventional H2S sensors, this sensor offers advantages of miniaturization, low cost, high selectivity, and electrolyte-free analyte detection.

Summary: Rare-earth doped glasses have shown potential applications in light-emitting devices. However, developing silicate glasses with excellent photoluminescence performance remains difficult. In this study, we investigated the reduction of rare-earth ions in doped glasses through heating in a hydrogen gas atmosphere or X-ray irradiation. We successfully synthesized Al2O3-SiO2 glasses doped with Sm3+ and Eu3+ ions, which exhibited strong photoluminescence. The Sm3+ and Eu3+ ions were reduced to their divalent states when heated in hydrogen gas, while only Sm3+ ions were reduced to Sm2+ ions when irradiated with X-rays. It was also found that the reduced Sm2+ ions in the glass could easily be oxidized to Sm3+ ions by heating in air. The fast redox reaction between Sm3+ and Sm2+ ions makes the Sm3+-doped Al2O3-SiO2 glasses suitable for X-ray therapy and sensor applications.

Summary: In this study, a lysosome-targeting buffering fluorogenic probe (Lyso-BFP) was designed and synthesized, demonstrating excellent photostability, pH specificity, and responsiveness to lysosomal acidification in living cells. The performance of Lyso-BFP in pH sensing was attributed to the inhibition of the photo-induced electron transfer process. Lyso-BFP allowed for wash-free imaging and long-term real-time monitoring of lysosome pH changes based on its off-on fluorescence behavior and buffer strategy.

Summary: This study developed a high-performance gas sensor for formaldehyde detection by modifying ZnSnO3 with ZnO QDs and SnO2 QDs. The modified sensor showed improved sensing response and lower working temperature. The presence of ZnO QDs formed rich heterojunctions, increased surface area, and provided oxygen deficiency for formaldehyde sensing reaction, thus enhancing the sensor performance. This research provides an alternative method to enhance the sensing properties of MOS by QDs modification.
