Promising new catalysts for hydrogen fuel cells

Hydrogen fuel cells hold a lot of promise as sustainable and eco-friendly energy sources to power transportation by land, air and sea. But traditional catalysts used to drive chemical reactions in hydrogen fuel cells are ...

The handedness of light holds the key to better optical control

Researchers at Aalto University's School of Electrical Engineering have developed a new approach to control the properties of a light beam. By using the handedness of the light beam, the technique achieves significantly enhanced ...

Blood pressure e-tattoo promises continuous, mobile monitoring

Blood pressure is one of the most important indicators of heart health, but it's tough to frequently and reliably measure outside of a clinical setting. For decades, cuff-based devices that constrict around the arm to give ...
