A UK-based scientist has developed a compact, affordable sensor that can detect the presence ... charges in the active material. When hydrogen is present, it reacts with the oxygen, reversing this ...

When hydrogen is present, it reacts with the oxygen, reversing this effect and causing a rapid drop in electrical current. This change is fast and reversible at room temperature up to 120 °C. The ...

The sensor operates using a process called p-doping, where oxygen molecules increase the concentration of positive electrical charges in the active material. When hydrogen is present, it reacts with ...

This functionality is maintained across a broad temperature range, from standard room temperature up to 120 degrees Celsius (248°F). The new hydrogen sensor underwent rigorous testing in ...

Hydrogen sensor. Credit: Thomas Anthopoulos. As the world moves toward cleaner energy, hydrogen is seen as a key alternative to fossil fuels. However, hydrogen is clear, odorless, and highly ...

Scientists at The University of Manchester have unveiled a hydrogen ... and reversible at room temperature up to 120°C, making it ideal for real-world applications. The sensor has already been ...

A breakthrough hydrogen sensor is here, according to a report from Tech Xplore. Developed by researchers at the University of Manchester and King Abdullah University of Science and Technology, this ...

Stadler is also supplying eight battery-electric trains for Chicago’s Metra commuter railroad system. In 2019, the railcar manufacturer opened a production facility in Salt Lake City. Stadler’s Ritter ...

Abstract: In this article, a fiber-optic hydrogen sensor based on a cascaded Fabry–Perot interferometer (FPI) structure and vernier effect is proposed and experimented. The sensor is mainly composed ...
