Article Synopsis
- Quantum dots (QDs) are used for a novel nitrogen dioxide (NO) fluorescence gas sensor, which combines QDs with silica microspheres and silica aerogel to enhance performance.
- The composite nanofilm improves gas diffusion and sensitivity, showing a strong linear response to NO gas within a range of 0-10 ppm, and achieves an ultra-low detection limit of 0.096 ppm.
- The sensor maintains stable fluorescence over 60 days, making it an effective solution for environmental monitoring and other applications requiring precise NO detection.
Article Synopsis
- Fluorescent sensors, like those made with quantum dots (QDs), provide accurate measurements and resist electromagnetic interference due to their electrical insulation.
- The developed optical humidity sensor uses a QDs nanocomposite film created from polyvinyl alcohol and SiO microspheres, detecting humidity through changes in QDs fluorescence.
- The sensor responds linearly to relative humidity (5%-97%), has quick response times (25s/20s), maintains stability for over 180 days, and is expected to be useful for environmental monitoring applications.
For an energy-efficient induction machine, the life-cycle cost (LCC) usually is the most important index to the consumer. With this target, the optimization design of a motor is a complex nonlinear problem with constraints. To solve the problem, the authors introduce a united random algorithm.
