Increasing efficiency in artificial photosynthesis

Chemical engineers at EPFL have developed a new approach to artificial photosynthesis, a method for harvesting solar energy that produces hydrogen as a clean fuel from water.

Growing algae outside of wastewater

Growing algae in wastewater has been a hot topic in research for years. News reports for decades have touted the latest research as bringing us within reach of new sources of fertilizer or environmentally friendlier biofuel.

Researchers find whimsy at the nano scale

At extremely small scales, looks can be deceiving. While at first glance you might see lily pads floating on a tranquil pond, this image is actually a clever adaptation of a snapshot taken on a scanning electron microscope.

Salvaging rare earth elements from electronic waste

Manufacturers rely on rare earth elements, like neodymium, to create strong magnets used in motors for electronics including hybrid cars, aircraft generators, loudspeakers, hard drives and in-ear headphones. But mineral deposits ...

Synthetic biology yields easy-to-use underwater adhesives

Several marine organisms, such as mussels, secrete adhesive proteins that allow them to stick to different surfaces under sea water. This attractive underwater adhesion property has inspired decades of research to create ...

Preventing data leak with dual-band metahologram

New frontiers have opened in the world of preventing data breaches by using light of two different wavelengths—visible and infrared light. This is achieved by using a new material called a metasurface that makes extreme ...
