Superfast light source made from artificial atom

29-Apr-2016

All light sources work by absorbing energy - for example, from an electric current - and emit energy as light. But the energy can also be lost as heat and it is therefore important that the light sources emit the light as quickly as possible, before the energy is lost as heat. Superfast light ...

Biotech breakthrough: Sunlight can be used to produce chemicals and energy

06-Apr-2016

Researchers at the University of Copenhagen have discovered a natural process they describe as reverse photosynthesis. In the process, the energy in solar rays breaks down, rather than builds plant material, as is the case with photosynthesis. The sunlight is collected by chlorophyll, the same ...

New patent on fast measurements in liquids

27-Jan-2016

A new invention will open the doors for an entirely new way of measuring properties within liquids. The invention, a sol-gel matrix, will make it possible to perform measurements that are reliable, incredibly rapid and can be conducted over extended periods of time. The development will be a boon ...

Sea urchin spurs new ideas for lightweight materials

12-Nov-2015

Materials researchers love sea creatures. Mother-of-pearl provokes ideas for smooth surfaces, clams inspire gluey substances, shark's skin is used to develop materials that reduce drag in water, and so on. Researchers at the University of Copenhagen's Department of Chemistry have now found a ...

Nanowires could be the LEDs of the future

30-Jun-2015

The latest research from the Niels Bohr Institute shows that LEDs made from nanowires will use less energy and provide better light. The researchers studied nanowires using X-ray microscopy and with this method they can pinpoint exactly how the nanowire should be designed to give the best ...

Quantum communication controlled by resonance in 'artificial atoms'

08-Aug-2013

Researchers at the Niels Bohr Institute, together with colleagues in the US and Australia, have developed a method to control a quantum bit for electronic quantum communication in a series of quantum dots, which behave like artificial atoms in the solid state. The results have been published in ...

Danish chemist aims to bring supermolecules to the world

14-Jan-2013

With applications spanning from non-shrink dental fillings to DNA-drugs the so-called dendrimers are a near magical material. Now a chemist from the University of Copenhagen has vowed to make the weird molecules famous. When a molecule's structure resembles that of two tree crowns growing into ...
