Add some sugar to the slurry if you would like it to be more acidic. New research from Maibritt Hjorth and her colleagues shows that sugar can replace sulphuric acid as a means of reducing ammonia emissions. Photo: Peter F. Gammelby.

Simple sugar reduces emissions from ammonia

Agriculture can probably halve emissions of harmful ammonia by adding sugar to the slurry. New research from Aarhus University suggests that sugar can replace sulphuric acid as a method of reducing ammonia emissions - to the benefit of organic farming and biogas production.

New milestone for design of biological medicins

A new generation of biological medicines is on the way: Recombinantly engineered antibodies that are much more efficient and versatile than those produced by the body. They are also far better than conventional recombinant antibodies, which mimic the natural ones – and it will be possible to produce them much more cheaply.

Researchers have developed a new technology for charging flow batteries with solar power. It looks as though this could be very significant for the supply of electricity to private consumers in future. (Photo: Anders Trærup)

The Department of Engineering has been awarded a Marie Curie Fellowship grant of DKK 1.6 million. This provides a postdoctoral position with a specific focus on organic flow batteries.

Researchers find storage capacity in new solar cells

A new type of solar cell converts light into chemical energy and stores it in tanks containing liquids, so it can be taken out again when required. The idea is simple, but it has wide-ranging potential. Researchers are testing a new method for charging flow batteries with solar power.
