Eco-friendly flying is on the horizon

All over the world, researchers are developing new technologies to achieve this goal. One focus of developments is the idea of using hydrogen-powered engines for aircraft in the future. The aircraft companies, though, face the challenge of storing this energy source. Hydrogen turns liquid when cooled to minus 253 degrees Celsius, and only then can Read more about Eco-friendly flying is on the horizon[…]

Joining process with reactive nano-multilayers

Reactive nano-multilayers are considered to be a revolution in joining technology. They are envisaged for joining heat-sensitive materials that would otherwise be damaged or even destroyed upon conventional soldering. But soldering with reactive foils proves to be tricky due to the volatile nature of the reactive foils. Empa researchers have now succeeded in refining the Read more about Joining process with reactive nano-multilayers[…]
