Self-cleaning surfaces protect against the transmission of bacteria and viruses

28/01/2022

In times of high risk of infection, effective protective measures are needed. Avoiding transmission routes via contaminated surfaces is an important part. It is known that photocatalytically active coatings reduce the microbial load.

Automated insulin delivery for young children with diabetes via Android app

27/01/2022

Families with young children who have type 1 diabetes use insulin pumps that require a lot of effort to operate. Scientists from all over Europe, including researchers from Leipzig University Hospital, the only site involved in Germany, have shown for the first time in a clinical trial that automated insulin delivery is safe and effective even at the age of one to seven years.

"Crazy" light emitters: Physicists see an unusual quantum phenomenon

26/01/2022

Scientists of the Cluster of Excellence ct.qmat–Complexity and Topology in Quantum Matter have experimentally discovered an unusual quantum phenomenon for the motion of luminescent electronic quasiparticles in atomically-thin semiconductors. The results were published in the Physical Review Letters journal.

Smart sensor detects leaks

20/01/2022

The cumbersome search for leaks in air compressor units could soon be made much easier: Along with SICK AG, Fraunhofer IPA is developing an ancillary leak detection service for a smart flow sensor. Self-learning algorithms evaluate the readings and in so doing identify leaks.

Bone growth inspired "microrobots" that can create their own bone

19/01/2022

Inspired by the growth of bones in the skeleton, researchers at the universities of Linköping in Sweden and Okayama in Japan have developed a combination of materials that can morph into various shapes before hardening.

Learning from dust: compare health risks of microparticles

18/01/2022

Researchers at the University of Bayreuth want to find out the consequences of inhaled microplastics. In order to better understand them, they have conducted an interdisciplinary study to find out how the health risks of particles such as soot, grinding dust or asbestos are related to their physical properties.
