Rapid formation of a shelter-in-place using a combination of vortex flow and chemical oxidation for indoor environments containing neurotoxic gases

Hollow Mesoporous SnO2/Zn2SnO4 Heterojunction and RGO Decoration for High-Performance Detection of Acetone

“…With the continuous progress of human society, gas emission with various poisonous and harmful compounds from industrial processes is getting more attention in environmental protection and public safety. − Among these hazardous gases, volatile organic compounds (VOCs) are considered the main reason for extreme weather and chemical smog, which would endanger seriously human health because of their intrinsic irritant and carcinogenic. , Continuous exposure to the VOC environment would increase the probability of respiratory diseases and cancer. , Especially, acetone is a common chemical solvent in industry production, which can result in paralysis centralis along with fatigue, nausea, headache, dizziness, irritability, and even coma. , Recently, some investigations demonstrated that the acetone concentration of exhaled gases originating from diabetics is higher than that of healthy people. , Therefore, acetone is believed to be a gas marker to diagnose diabetes instantaneously by monitoring acetone content. − To date, different methods have been applied to detect and monitor acetone concentration. In these ways, gas chromatography is identified as an efficient and accurate technology for detecting gas content. , Unfortunately, the supporting facilities for this technique are expensive and complex to realize real-time monitoring of acetone.…”
