hydrogens

Researchers at the University of Sydney have discovered that adding molybdenum to steel, combined with metal carbides, significantly improves its ability to trap hydrogen, potentially solving the issue of hydrogen embrittlement. This breakthrough, using advanced cryogenic atom probe tomography, could pave the way for large-scale hydrogen transport and storage solutions, essential for transitioning to a hydrogen economy.Solving embrittlement is a multi-billion-dollar question.Why hydrogen causes steels to become brittle…

This is today’s edition of The Download, our weekday newsletter that provides a daily dose of what’s going on in the world of technology. When hydrogen will help climate change—and when it won’t. Hydrogen is often heralded as a climate hero because when it’s used as a fuel in things like buses or steel production, there are no direct carbon emissions to worry about. As the world tries to cut down on our use of fossil fuels, there could be plenty of new demand for this carbon-free energy source.But…

The new sensor is based on an optical phenomenon, plasmons, which occur when metal nanoparticles capture light and give the particles a distinct color. This color changes when the amount of hydrogen in the surroundings varies and the sensor can alarm at critical levels.
