Abstract
Gas sensors are crucial devices in various fields such as industrial safety, environmental monitoring, gas infrastructure including hydrogen use, and medical diagnostics. These sensors precisely measure the presence of gases on-site in different environments to ensure operational safety and efficiency. Designed for high sensitivity, stability, and reliability, gas sensors are..... More

Abstract
In hydrogen refueling stations, polymer O-rings are used for high-pressure hydrogen containers and transfer pipes to prevent gas leakage. A technology has been developed to measure the hydrogen uptake and diffusivity of the polymer materials used in these O-rings. The process involves charging the polymer material with hydrogen under a..... More
