Tracing volatile organic compounds is important for public safety and all 'smell' related issues. To this end, researchers introduce a fluid mechanics-based chamber design for an electronic nose that ...

Volatile organic compounds (VOCs) are compounds made of carbon that are emitted as gases into the air. They have a high vapor pressure and low water solubility, and many VOCs have adverse health ...

The human nose, which has around 6 million olfactory receptors, can distinguish between at least 1 trillion different odors. Dogs have about 300 million of these receptors, with some scientists ...
