How quantum dots can 'talk' to each other

So-called quantum dots are a new class of materials with many applications. Quantum dots are realized by tiny semiconductor crystals with dimensions in the nanometre range. The optical and electrical properties can be controlled ...

Professor works to maximize efficiency of solar light pipes

If you have witnessed the rainbow pattern that dances on the surface of a CD or DVD, then you have seen diffraction at work. The disk acts as a diffraction grating, an optical element that disperses light into various colors ...

A high-tech textile to stay comfortable outdoors

Clothing, from tank tops to parkas, helps people adapt to temperatures outdoors. But you can only put on or take off so much of it, and fluctuations in weather can render what you are wearing entirely inadequate. In a new ...

Lunar Gateway will maintain its orbit with a 6 kW ion engine

When NASA sends astronauts back to the moon as part of the Artemis Program, they will be taking the long view. Rather than being another "footprints and flags" program, the goal is to create a lasting infrastructure that ...

Capturing energy from sunlight with dyes inspired by nature

As sunlight filters through a forest canopy, chlorophyll is hard at work capturing the energy of photons. Inspired by nature, researchers at NTNU are working on light-capturing dyes for solar cells to generate electricity.
