Summary: This study reports the growth of nanostructured tungsten oxide (WO3) thin film on SiO2 substrate under controlled oxidation conditions for NO sensing. The fabricated sensor demonstrates high selectivity, stability, and faster response/recovery time, with an ultra-high response for 1 ppm NO concentration at 250 degrees C. The ultra-high response is attributed to the high specific surface area and effective gas diffusion ability of the sensor.

Summary: Over the past few decades, the research on electrochromism has focused on altering the optical transmittance of electrochromic (EC) materials using a small applied voltage. Tungsten oxide (WO3) is commonly used in EC devices (ECDs) to achieve this effect. In this study, WO3 films were produced using a sol-gel spin-coating method, and the influence of various transparent conducting oxides (TCOs) on the construction of ECDs was investigated. The combination of fluorine-doped tin oxide (FTO) and indium-doped tin oxide (ITO) as the TCO and counter electrode, respectively, exhibited the highest coloration efficiency.

Summary: Multiferroic BiFeO3 particles with size of about 50 nm and good crystallinity were prepared via a simple sol-gel method and annealing. The VOCs sensing properties of BiFeO3 sensor were tested under both traditional thermal excitation and synergetic thermal-magnetic excitation, and the results showed improved performance under the latter condition. The effect of magnetic field on the sensor can be attributed to decreased defects on domain walls, excitation of gas molecules, and activation of surface-absorbed oxygen species.

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.
