Researchers have developed a sensor made from 'frozen smoke' that uses artificial intelligence techniques to detect formaldehyde in real time at concentrations as low as eight parts per billion, far ...

VOCs are extensively spread in the environment, causing a threat to human health. Thus, identifying VOC types and concentration are of critical importance in gas detection. The application of ...

Engineers turn biodegradable film into a high-performance VOC sensor that resets in minutes and cuts out complex materials. Study: Holographically sensing of volatile organic compounds using cellulose ...
