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 material lights up when detecting explosives

09-Feb-2016

Scientists have created a material which turns fluorescent if there are molecules from explosives in the vicinity. The discovery could improve e.g. airport security - and also it gives us an insight into a rather chaotic micro-world where molecules and atoms constantly are responding to their ...

Harnessing the oxidising power of air

01-Feb-2016

Researchers report the catalysis of a highly specific chemical reaction where oxygen from the air is one ingredient and the other, an organic molecule, is selectively "oxidised". A simple manganese compound catalyses this reaction. This type of methodology is an important step for the discovery ...

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 ...

Mega pollution on mega sites

22-Jan-2016

At the 13th Int. HCH & Pesticides Forum, new shocking cases of Mega-sites in Slovakia and Romania, at the eastern borders of the European Community showed the extent and the unacceptable threats to the health of the population. However, such mega-sites are also still present today in the EU ...

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 ...

Bold research into recycling CO2

02-Oct-2015

The scientific aims are bold, but the gains can be enormous. The new CADIAC research centre at Aarhus University will be the most ambitious venture in the world to date to find the best methods to convert CO2 into medicine, plastic and useful chemicals. Even on Mars. CO2, carbon dioxide, carbonic ...

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 ...

Elastocaloric materials enable more efficient, 'green' cooling

26-Mar-2015

Move over, vapor compression cooling technology. Emerging "elastocaloric" refrigeration is potentially much more efficient and, unlike vapor compression, relies on environmentally-friendly refrigerants. In elastocaloric materials a change in mechanical stress can create a change in temperature.In ...
