Accurate optical sensing

Hydrogen sensors have been the focus of research for many years. Scientists working for the University of Georgia and South Carolina’s Savannah River National Laboratory have now found a way to make it extremely easy to detect even minute traces of the gas. A research article about their new optical method for hydrogen sensing was published in the Nature Communications journal in April. “Our spark-free, optical-based hydrogen sensors detect the presence of hydrogen without electronics, making the process much safer,” said Tho Nguyen, an associate professor in the university’s Franklin College of Arts and Sciences and, together with the laboratory’s George Larsen, the co-principal investigator on the project.
