By means of chemistry, it can make good sense to transform the much-criticised waste material CO<sub>2</sub> into pharmaceutical products. (Photo: Anders Trærup, Aarhus University)
This image shows one of the chambers the researchers use to transform CO<sub>2</sub> into pharmaceuticals in one single process. Hazardous carbon monoxide is produced in the chambers and then turned into pharmaceuticals without being touched by human hands. (Photo: Anders Trærup, Aarhus University)

CO2 – from waste material to pharmaceutical in one single process

In one single process, Aarhus researchers are producing medicine out of carbon dioxide (CO2) – the major climate culprit. The process simultaneously spares workers in the pharmaceutical industry from contact with hazardous carbon monoxide.

Graphene is a two-dimensional material that is just one carbon atom thick, so it takes up very little space – even when stacked. On the other hand, it acquires some interesting properties when two layers are put together – as in this little plate shown here by PhD student Søren Ulstrup. Photo: Peter F. Gammelby, Aarhus University.

A double layer of graphene keeps on charging

The thin carbon material graphene is even better at converting light to electricity than previously thought – it just requires two layers. Researchers at Aarhus University have just shown that stacking two layers on top of each other can – by means of light – create ‘hot’ electrons with a long service life. This will make it possible to use a…

This figure shows simulations of the electrons’ path through the crystal. The horizontal direction is the electron’s position, and the vertical direction is its angle. A particle that is trapped around a crystal plane is characterised by a closed circle in this diagram. Each ‘ø’ along the horizontal direction therefore corresponds to particles trapped around their individual crystal plane. The diagram thus shows how some particles are trapped, while others escape one crystal plane to be trapped again by another.
The figure shows the atoms (black dots) in the crystal lattice, and a positron (red) and an electron (blue), respectively, that are channelled through the crystal. By producing the crystal a special way, it is possible to achieve planes with a built-in distance ‘d’ in the crystal lattice waves with an amplitude ‘a’ and a wavelength ‘lambda’ as shown. Because the wavelength can be made a hundred thousand times smaller than by conventional methods, it is possible to produce very high-energy radiation. (Illustration: UVH modified – author unknown)
In a conventional undulator, the magnets – shown in light blue and red – are placed alternately with north poles and south poles aimed towards the electron beam, shown in green. The magnetic field thus forces the electron beam to vibrate, whereby light or other high-energy radiation is emitted, shown in yellow. In a crystalline undulator, the magnets are replaced by crystal planes whose direction changes so that the electron beam is forced in the same way to vibrate, but for a significantly shorter period.

Heading towards a gamma-ray laser?

A group of Aarhus University researchers headed by Ulrik Uggerhøj has produced intense gamma radiation for the first time ever by sending an electron beam through a specially made silicon-germanium (SiGe) crystal – known as a crystalline undulator.

Viral infections could be stopped by boosting natural protein

An international research team has published results showing that boosting the protein OASL may help the body to detect and fend off certain viral infections on its own. The discovery could lead to new, more effective treatments for many dangerous viruses such as hepatitis C and influenza.

Aarhus University students are European science show champions

Students from Aarhus University’s Chemistry Show and Physics Show, along with students from the Technical University of Denmark (DTU), are the newly crowned European science show champions. They won the unofficial European Science Show Championship, held in connection with the Science in the City event in Copenhagen.

European Science Show Championship

This weekend, the best science shows in Europe will compete against each other to see who can present the most spectacular show. Aarhus University (AU) and the Technical University of Denmark (DTU) have combined the three best Danish shows in one joint national team.

Several electrodes on the head are currently required to achieve sufficiently good data quality when registering electrical activity patterns in the brain. Researchers at the Department of Engineering, Aarhus University, are now producing a small ear computer that can pave the way towards new EEG applications. (Photo: Lise Balsby)

Sapere Aude grants awarded to four Science and Technology researchers

The Danish Council for Independent Research (DFF) has just awarded research grants in the Sapere Aude career programme, and Science and Technology is represented with four researchers.

Hans Brix and Peter Henriksen have been appointed heads of the Department of Bioscience. They manage the department jointly, but taking finances and staff into consideration, Dr Henriksen is responsible for Bioscience Roskilde, Kalø and Silkeborg, while Professor Brix is responsible for Bioscience Aarhus.

The Vikings were driven out of Greenland by the cold

It has always been a mystery as to why the Vikings left Greenland after almost five centuries of settlement. New geological studies show that climate changes with cooling and more icy conditions may have caused the end of the settlements.

Denmark’s new research vessel sets sail for Bornholm and the People Meeting

On 10 June, the AURORA sets off on its maiden voyage from Aarhus to Allinge. The ultra-modern vessel is only two months old and it will be open to the public at Denmark’s annual Political Festival on Bornholm – the Folkemødet (People Meeting) – before continuing north-east on a Baltic expedition.

Researchers will change European energy consumption

In the coming years, Aarhus University will spearhead a major European energy research project and analyse patterns in the energy behaviour of private consumers. The aim is to make Europeans better at using power when there is plenty available.
