Paving the way for diagnostics
Two-dimensional materials such as graphene are not only ultrathin, but also extremely sensitive. Researchers have therefore been trying for years to develop highly sensitive biosensors that utilise this property. Graphene-based field-effect transistors, for example, could register the tiniest changes in the electronic properties caused by the molecules when they interact with this atomically thin layer.

Rodents inspire dentistry
Researchers discover an iron-containing material in the outer enamel of rodent teeth that could also make human teeth more resistant Rodents such as beavers, nutrias (coypu) , squirrels and rats have particularly strong, elongated front teeth that grow continuously over the course of their lives. Using state-of-the-art imaging techniques, researchers at the Max Planck Institute for Solid State Research in Stuttgart have now elucidated the tooth structure of various rodent species at the nanometre scale.

Leipzig physicists show that light can generate electricity even in translucent materials
News from Some materials are transparent to light of a certain frequency. When such light is shone on them, electrical currents can still be generated, contrary to previous assumptions. Scientists from Leipzig University and Nanyang Technological University in Singapore have managed to prove this. "This opens new paradigms for constructing opto-electronic and photovoltaic devices, such as light amplifiers, sensors and solar cells," says Inti Sodemann Villadiego, Professor at the Institute of Theoretical Physics at Leipzig University.

Breakthrough for battery production with sulphur cathodes
Electromobility and portable electronic devices such as laptops and cell phones are unthinkable without the use of lithium-ion batteries. The problem: highly toxic materials such as cobalt are often used for the cathodes of these batteries, which endanger the environment and the health of people in the countries where they are mined.

How surface roughness influences the adhesion of soft materials
Research team discovers universal mechanism that leads to adhesion hysteresis in soft materials Adhesive tape or sticky notes are easy to attach to a surface, but are difficult to remove. This phenomenon, known as adhesion hysteresis, can be fundamentally observed in soft, elastic materials: Adhesive contact is formed more easily than it is broken.

Battery recycling: China is in first place
China covers its demand for lithium, cobalt and nickel for batteries by recycling, ahead of Europe and the USA. With the increasing production of batteries for electric vehicles, the demand for the necessary raw materials is also rising. In view of the supply risks, environmental problems and precarious working conditions associated with the extraction and transportation of these raw materials, the recycling of battery materials has become an important topic in science, politics and industry.
