Twisting molecule wrings more power from solar cells

Inside a solar cell, sunlight excites electrons. But these electrons often don't last long enough to go on to power cell phones or warm homes. In a promising new type of solar cell, the solar-excited electrons have better ...

New bioimaging technique is fast and economical

A new approach to optical imaging makes it possible to quickly and economically monitor multiple molecular interactions in a large area of living tissue—such as an organ or a small animal; technology that could have applications ...

Interface engineering for stable perovskite solar cells

The lifetime of perovskite solar cells is significantly enhanced by using few-layer molybdenum disulphide (MoS2) flakes as an active buffer interface layer. Researchers from the Graphene Flagship show that interface engineering ...

Watching apoptosis in 3D

A promising approach for watching cell signaling processes in their physiological context: Scientists visualize apoptosis in live zebrafish using fluorescence lifetime imaging with optical projection tomography to map FRET ...

Biomedical imaging at one-thousandth the cost

MIT researchers have developed a biomedical imaging system that could ultimately replace a $100,000 piece of a lab equipment with components that cost just hundreds of dollars.
