    Working PrinciplePower ConsumptionHumidity and TemperatureQuantification LimitationsData Interpretation ResearchThese sensors work by initiating REDOX chemical reactions in a porous layer heated by a filament. This results in ionised local air and modified electrical resistance across the sensor, somewhat proportional to the air quality: A cleaner air will produce less such reactions, resulting in poor conductivity and increased resistance, while a polluted air will increase conductivity resulting in lower resistance.See more on confining methylene blue in three ...2020-11-1Benefited from the porous and conductive structure of the product, the fast-reversible electrochemical reaction of methylene blue, and the spatial confinement effect of the methylene blue confined in reduced graphene oxide, the as-prepared product exhibits a high-rate capability (311 and 262 F g −1 at 1 and 20 A g −1, respectively) and an ...
