Making equal-size colloidal quantum dots

Quantum dots (QDs) are semiconductor particles only a few nanometers across that, thanks to their small size, exhibit peculiar optical and electronic properties due to quantum mechanics. With existing and foreseen applications ...

Antarctic Circumpolar Current flows more rapidly in warm phases

Earth's strongest ocean current, which circulates around Antarctica, plays a major role in determining the transport of heat, salt and nutrients in the ocean. An international research team led by the Alfred Wegener Institute ...

A better look at how particles move

If you take a bucket of water balloons and jostle one of them, the neighboring balloons will respond as well. This is a scaled-up example of how collections of cells and other deformable particle packings respond to forces. ...

Small 'snowflakes' in the sea play a big role

In the deep waters that underlie the productive zones of the ocean, there is a constant rain of organic material called "marine snow." Marine snow does not only look like real snow but also behaves similarly: Large flakes ...

Advance in 'optical tweezers' to boost biomedical research

Much like the Jedis in Star Wars use the Force to control objects from a distance, scientists can use light or optical force to move very small particles. The inventors of this ground-breaking laser technology, known as "optical ...
