The design is lightweight, robust, and produces hydrogen nearly ten times faster than conventional cells. Its durability under extreme conditions and simplified five-step manufacturing process drastically reduce system weight, making it a promising breakthrough for green, high-performance fuel cells in aviation and space missions.

Friction-based landing of drones on moving vehicles

Researchers at the University of Sherbrooke (Canada) have developed DART, a quadcopter using friction shock absorbers and reverse thrust to land safely on fast-moving vehicles. Drones, though common in photography, logistics, and agriculture, still face high risks during landing, which causes nearly half of the accidents. By levelling before touchdown and absorbing impact energy, DART achieves stable landings at speeds up to 110km/hr, expanding operational safety and enabling autonomous missions in dynamic, challenging environments.

Turning waste wood into biodegradable circuit boards

Researchers at Empa, Switzerland's Federal Laboratories for Materials Science and Technology, have developed biodegradable printed circuit boards made from wood-based lignocellulose, offering an eco-friendly alternative to traditional fossil-fuel epoxy boards. Using natural cellulose fibres and lignin, the team creates high-performance substrates that can compost after use. Prototypes like computer mice and RFID cards function normally, while components remain recyclable. Future efforts aim to boost water resistance and scale industrial production, advancing sustainable electronics.
