Abstract Highly porous polypyrrole (PPy)‐coated TiO 2 /ZnO nanofibrous mat has been successfully synthesized. The core nanofibers have an average diameter of ca. 100 nm and the shell ultrathin PPy layer a thickness 7 nm. NH 3 gas sensor using as‐prepared material exhibited fast response over wide dynamic range high sensitivity with detection limit 60 ppb ( S / N =3). Compared to conventional pristine film, improved performance in can be attributed free access minimized diffusion resistance...
Sarcopenia, a condition characterized by diminished skeletal muscle mass, strength, and function, accompanied inflammation oxidative stress, remains an area of limited exploration concerning its correlation with the Oxidative Balance Score (OBS).
Though the chemical origin of a metal oxide gas sensor is widely accepted to be surface reaction detectants with ionsorbed oxygen, how sensing material transduces into an electrical signal (i.e., resistance change) still not well-recognized. Herein, single ZnO NW used as model investigate relationship between microstructure and performance. It found that acetone responses arrive at maximum diameter (D) ∼110 nm D range 80 400 nm, which temperature independent in region 200 °C–375 °C. The...
Water vapor is one of the main factors that deactivate an ozone decomposition catalyst, which limits its applications under practical conditions. In this work, a heterostructured Ni/NiO nanocatalyst synthesized using citric sol–gel method, displays 100% removal efficiency to 1000 ppm at room temperature in dry flow (space velocity 240 000 mL g–1h–1). Importantly, still >98% high relative humidity RH 90% after 8 h testing, twice pure NiO nanoparticles. The resistance can be interpreted as...
Metal sulfide Zn1–xCdxS nanowires (NWs) covering the entire compositional range prepared by one step solvothermal method were used to fabricate gas sensors. This is first time for ternary metal nanostructures be in field of sensing. Surprisingly, sensors based on found exhibit enhanced response ethanol compared those binary CdS and ZnS NWs. Especially sensor (x = 0.4) NWs, a large (s 12.8) quick rise (2 s) recovery (1 observed at 206 °C toward 20 ppm ethanol, showing preferred selectivity. A...
The chemical and optical properties of 1D single-crystalline cadmium sulfide (CdS) nanowires (NWs) synthesized by a solvothermal method were discussed systematically. CdS NW was characterized using different analytical techniques. In our work, employed as the active nanomaterial to detect ethanol gas for first time showed good sensing performance. Especially, fast response (0.4 s) recovery speed (0.2 100 ppm much faster than reported values. visible-light detector based on NWs demonstrated...
Diodes based on p-n junctions are fundamental building blocks for numerous circuits, including rectifiers, photovoltaic cells, light-emitting diodes (LEDs), and photodetectors. However, conventional doping techniques to form p- or n-type semiconductors introduce impurities that lead Coulomb scattering. When it comes low-dimensional materials, controllable stable is challenging due the feature of atomic thickness. Here, by selectively depositing dielectric layers Y2O3 AlN, direct formation...

Abstract Nowadays, it is still technologically challenging to prepare highly sensitive sensing films using microelectrical mechanical system (MEMS) compatible methods for miniaturized sensors with low power consumption and high yield. Here, cross-linked SnO 2 :NiO networks were successfully fabricated by sputtering target onto the etched self-assembled triangle polystyrene (PS) microsphere arrays then ultrasonically removing PS templates in acetone. The optimum line width (~ 600 nm) film...
Conventional methane gas sensors based on catalytic combustion have the drawbacks of high working temperature, low thermal stability and small measurement range. To improve their performance, cerium, which possesses oxygen storage release ability, was introduced via nanotechnology to prepare Ce-contained nanostructure elements. Three kinds elements with different carriers: Al2O3, n-Al2O3 n-Ce-Al2O3 were prepared separately fabricated (Pt-Pd/Al, Pt-Pd/n-Al, Pt-Pd/n-Ce-Al). The performances...
