Progress for silicon carbide LED

Researchers from Technical University of Denmark in collaboration with LiU researchers show how white light can be produced from a single layer of silicon carbide. Previously, only the warm white part of light could be produced.

A dairy farm with its own climate-smart ecology

It is biogas that gets the ecological circulation going on Sweden’s largest dairy farm, Wapnö. “Using biogas is not a goal in itself: it’s a means to an end,” says Lennart Bengtsson, managing director at Wapnö.

"You can't just prohibit studded tyres"

Road vehicles. particularly those with studded tyres, wear down road surfaces and create particles. These are in the air we breathe. What do we know about their effects on health? And how can we best mitigate the problems they cause in our cities?

Farmers unite to make biogas profitable

Eleven farmers around the town of Alvesta in Småland agreed in 2014 to build a joint biogas facility. The result is a profitable facility, 4,500 kg of biogas every day, and fertiliser with a nutrient content that is 10% higher for the fields.

Storing energy in roses

Eleni Stavrinidou leads a research group at the Laboratory of Organic Electronics working with electronic plants. The research has led to a completely new multidisciplinary field of research with a huge potential benefit to society.

Floating homes - climate change and our cities

As the climate around us changes, our cities are affected. When a sudden downpour or a heatwave hits, residents still have to manage their day-to-day lives. In Sweden people are working on several fronts to adapt our cities to climate change.

Vallastaden - potential for a smart city

Aspects such as efficient use of resources and social interaction have been included in the planning of Vallastaden. Malin Granath, researcher in information systems, believes that it may eventually be possible to achieve economic sustainability.

Sweden’s largest biogas reactor to Nymölla?

Stora Enso’s pulp and paper mill at Nymölla may become home to Sweden’s largest biogas reactor. The wastewater from the mill could be collected and digested. A project to build such a plant has been awarded SEK 58 million from Klimatklivet.

Moving to biogas saves Kalmar money

When Kalmar County invited tenders for operating public transport, biogas was the obvious preferred option. “Our starting point was that we believed it to be best for the county,” says Ulf Nilsson, chairman of the Kalmar Regional Association.

The greatest threat against biogas is from Denmark

The municipal energy and waste-management company NSR was an early adopter of biogas technology. It subsequently separated its operations and concentrated solely on waste management. The focus on biogas is not by any means safe from threats.

Dogs´social skills linked to oxytocin sensitivity

The tendency of dogs to seek contact with their owner is associated with genetic variations in sensitivity for the hormone oxytocin, according to a new study from Linköping University.

Celebrating LiU’s collaboration with China

A sign celebrating the joint research centre in urban sustainable development between LiU and Guangzhou University has been unveiled. The university managements and mayors from Linköping and Guangzhou attended the ceremony.

IBS colon reacts differently to bacteria

The intestinal barrier of patients with the gastrointestinal disease IBS allows bacteria to pass more freely than in healthy people, according to a new study from LiU. It is the first study that investigates IBS using living bacteria.

Jubilee Symposium with roses, robots and autonomous cars

Plants that store energy, printed electronics, social robots and visualisation technology that will make autonomous cars a reality. These are some of the research areas to be presented during the Knut and Alice Wallenberg Jubilee Symposium

Many advantages of dry digestion

Sweden’s first dry digestion plant is located at Mörrum, where food waste in brown bags is converted to useful biogas. The waste is digested at the consistency as it has when it arrives. One bag is sufficient for 2.5 km of fossil-free transport.

A biogas bus takes a tour

More than 30 researchers and representatives for companies involved in the Biogas Research Center, BRC, spent three days this summer touring southern Sweden to exchange experiences with companies and decision-makers.

Five times the computing power

Researchers at Linköping University have developed a method to increase by a factor of five the computing power in one type of standard chip. The new method is both simple and smart, but the road to publication has been long.

Swedish-Chinese collaboration in 5G technology

People say that 5G will be upon us in 2020, offering 1000 times more traffic at rates of hundreds of Mbit/s. There are many research projects in 5G under way, but probably only one of them is a Swedish-Chinese collaboration.

Vegetable colouring agent may suppress inflammation

Several highly coloured vegetables and fruits contain lutein. A study by researchers at LiU suggests that lutein has anti-inflammatory effects in patients with coronary artery disease.

High-precision control of printed electronics

Printed electronic transistor circuits and displays, in which the colour of individual pixels can be changed, are two of many applications of ground-breaking research at the Laboratory of Organic Electronics, published in Science Advances.

Spinning electrons open the door to future hybrid electronics

A discovery on how to control spinning electrons paves the way for novel hybrid devices that could outperform existing semiconductor electronics. Researchers at LiU use a topological insulator, a fascinating matter with unique electrical properties.

Innehållet i gröna påsen blir till biogas i reaktorn

They found the bacteria that like fat

Fat in a biogas reactor behaves as it does at home in the kitchen: it’s sticky and clogs things up. The researchers at the Biogas Research Center, however, have discovered a helping hand, a bacterium that can break down the troublesome fat molecules.

Working memory heavily loaded after hearing loss

Researchers from the Linnaeus Centre HEAD presented results for leaders in the field of cognitive hearing at a four-day conference in Linköping.

Short, high-intensity running substantially stresses the body

A relatively short run, if taken as fast as possible, is more stressful to the body than you might think, according to research from LiU. Among other things, the level of stress hormone cortisol remains high for several hours.
