Wearable hologram sensor that can detect toxic gases

Gas accidents such as toxic gas leakage in factories, carbon monoxide leakage of boilers, or toxic gas suffocation during manhole cleaning continue to claim lives and cause injuries. Developing a sensor that can quickly detect toxic gases or biochemicals is still an important issue in public health, environmental monitoring, and...

Gas detection technology boosts fight against COVID-19

Gas detection can play a major role in the deployment of the Pfizer-Biontech vaccine. This vaccine requires storage and transportation at -70°C in sealed containers due to its mRNA (Messenger RNA) molecule technology. Such a low temperature is maintained using dry ice. Dry ice is solid, frozen carbon dioxide (CO2). However, at temperatures above -78°C, CO2 sublimates, which is when it becomes gaseous and potentially...
