Ultra-sensitive optical sensor can reduce hydrogen’s risks

AI technology led the way

09-Dec-2022 - In the pursuit of clean and renewable energy, hydrogen plays an important role. But a major challenge facing this transition is that the gas is explosive when mixed with air. For this reason, it is crucial to be able to detect hydrogen leaks as early as possible. Now researchers at Chalmers ...

Recycling Greenhouse Gases

Novel perovskite catalysts could be used wherever methane and carbon dioxide are produced simultaneously

05-Sep-2022 - CO2 and methane can be turned into valuable products. But until now the catalysts required for such reactions quickly lose their effectiveness. TU Wien has now developed more stable alternatives. Wherever the production of harmful greenhouse gases cannot be prevented, they should be converted ...
