As the number of particles in a physical system increases, its properties can change and different phase transitions (i.e., shifts into different phases of matter) can take place. Microscopic systems ...
Vargas et al. designed a collection of low-cost sensors and circuits for plasma experiments, providing easier access to ...
Optical sensors articles from across Nature Portfolio Optical sensors are a broad class of device for detecting light intensity.
There must be no chemical reaction between the sensor material and the sample. Use a sensor with a low cell constant (0.01 to 0.1 cm-1) for low conductivity measurements and a sensor with a higher ...
Discover how cutting-edge Leak Detection Sensor Networks (LDSNs) are transforming fenceline monitoring by delivering real-time emissions data, enabling proactive risk management, and helping ...
When a gas absorbs infra-red rays, it is heated and its pressure increases. If the stream of radiation is interrupted at sonic frequency, there are rapid changes of pressure in the gas.
This review explores the recent progress of electrical, gravimetric, and optical sub-ppm ammonia gas sensors and their humidity tolerance at room temperature. By considering the humidity interference ...
Food safety assurance is crucial, particularly in identifying prohibited colors like brilliant blue (BB) that may pose significant health risks when used in food products. Surface plasmon resonance ...
Invisible to the untrained eye, DFOS technology turns standard fiber optic cables into long-range, high-resolution sensing ...
The gas sensor, based on a p–n heterojunction structure, was fabricated by vertically stacking a nanometer-thick layer of p-type cobalt phthalocyanine (CoPc) on a solution-processed n-type ...
