Only now in 2018 have researchers successfully demonstrated that hypothetical ‘particles’ that were proposed by Franz Preisach in 1935 actually exist. In an article published in Nature Communications, scientists from the universities in Linköping and Eindhoven show why ferroelectric materials act as they do. Ferroelectricity is the lesser-known twin of ferromagnetism. Iron, cobalt and nickel…

Researchers from Linköping University and the Royal Institute of Technology in Sweden propose a new device concept that can efficiently transfer the information carried by electron spin to light at room temperature – a stepping stone towards future information technology. They present their approach in an article in Nature Communications. In today’s information technology, light…

The waste-management system of the cell appears to play an important role in the spread of Alzheimer’s disease in the brain. A new study has focused on small membrane-covered droplets known as “exosomes”. It was long believed that the main task of exosomes was to help the cell to get rid of waste products. In…

It may in the future be possible to harvest energy with the aid of leaves fluttering in the wind. Researchers at the Laboratory of Organic Electronics at Linköping University have developed a method and a material that generate an electrical impulse when the light fluctuates from sunshine to shade and vice versa. “Plants and their…

Klas Tybrandt, principal investigator at the Laboratory of Organic Electronics at Linköping University, has developed new technology for long-term stable neural recording. It is based on a novel elastic material composite, which is biocompatible and retains high electrical conductivity even when stretched to double its original length. The result has been achieved in collaboration with…

Researchers at Linköping University in Sweden have discovered a previously unknown warning system that contributes to the body’s immune system. Mitochondria in the white blood cells secrete a web of DNA fibres that raises the alarm. The results have been published in the scientific journal PNAS, and may lead to increased knowledge about autoinflammatory diseases…

Researchers at the Laboratory of Organic Electronics, Linköping University, have developed the world’s first complementary electrochemical logic circuits that can function stably for long periods in water. This is a highly significant breakthrough in the development of bioelectronics. The first printable organic electrochemical transistors were presented by researchers at LiU as early as 2002, and…

Small shining molecules developed by scientists at Linköping University in Sweden can be designed to distinguish between plaque of different proteins in the brain. They may pave the way for better diagnosis of neurodegenerative diseases, such as Alzheimer’s disease, in which plaque forms from the amyloid beta or tau proteins. Researchers at Linköping University, LiU,…

Professor Martijn Kemerink of Linköping University has worked with colleagues in Spain and the Netherlands to develop the first material with conductivity properties that can be switched on and off using ferroelectric polarisation. The phenomenon can be used for small and flexible digital memories of the future, and for completely new types of solar cells.…

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, Linköping University. New groundbreaking results on these topics have been published in the prestigious scientific journal Science Advances. The researchers in organic electronics have a favourite material to…

A drug delivery ion pump constructed from organic electronic components also works in plants. Researchers from the Laboratory of Organic Electronics at Linköping University and from the Umeå Plant Science Centre have used such an ion pump to control the root growth of a small flowering plant, the thale cress (Arabidopsis thaliana). In the spring…

Taking tissue samples from the liver to diagnose fatty liver can be replaced in most cases by a painless magnetic resonance investigation. This is the conclusion of a new study from Linköping University in Sweden, published in the scientific journal Gastroenterology. The authors propose that the current value considered to be a normal amount of fat…

In November 2015, the research group presented results showing that they had caused roses to absorb a conducting polymer solution. Conducting hydrogel formed in the rose’s stem in the form of wires. With an electrode at each end and a gate in the middle, a fully functional transistor was created. The results were presented in Science…

The HIV virus increases the potency of the tuberculosis bacterium (Mtb) by affecting a central function of the immune system. This is the conclusion of a study carried out by researchers at Linköping University in Sweden. The discovery helps to explain why infection with HIV greatly increases the risk that infection by Mtb will progress…
