The power of combining different views. Lithium-Ion batteries presently are the ubiquitous source of electrical energy in mobile devices, and the key technology for e-mobility and energy storage. Massive interdisciplinary research efforts are underway both to develop practical alternatives that are more sustainable and environmentally friendly, and to develop batteries that are safer, more performing, and longer-lasting – particularly for applications demanding high capacity and very dense energy storage. Understanding degradations and failure mechanisms in detail opens opportunities to better…
A robot, designed to mimic the motion of a snail, has been developed by researchers at the University of Bristol. Adding to the increasing innovative new ways robots can navigate, the team, based at the Bristol Robotics Laboratory, fitted the robot with a sliding suction mechanism enabling the device to slide on water, a substitute of a snail’s mucus which also acts as an adhesive. The study, which was published today in the journal of Nature Communications, shows a novel…
North Carolina State University researchers have demonstrated a technique that allows people who manufacture metal machine parts with 3D printing technologies to conduct automated quality control of manufactured parts during the finishing process. The technique allows users to identify potential flaws without having to remove the parts from the manufacturing equipment, making production time more efficient. “One of the reasons people are attracted to 3D printing and other additive manufacturing technologies is that these technologies allow users to quickly replace…
Research examines the nature of explosive events in the magnetosphere. Southwest Research Institute is investigating an unusual event in the Earth’s magnetotail, the elongated portion of the planet’s magnetosphere trailing away from the Sun. Using data from NASA’s Magnetospheric Multiscale (MMS) mission, SwRI scientists are examining the nature of substorms, fleeting disturbances in the magnetotail that release energy and often cause aurorae. Since their launch in 2015, the MMS spacecraft have been surveying the magnetopause, the boundary between the magnetosphere…
The SPECULOOS project has revealed the existence of an Earth-sized planet around SPECULOOS-3, a nearby star similar in size to Jupiter and twice as cold as our Sun. The SPECULOOS project, led by the astronomer Michaël Gillon from the University of Liège, has just discovered a new Earth-sized exoplanet around SPECULOOS-3, an “ultracool dwarf” star as small as Jupiter, twice as cold as our Sun, and located 55 light-years from Earth. After the famous TRAPPIST-1, SPECULOOS 3 is the second…
A new nucleosynthesis process denoted the νr-process has been suggested by scientists from GSI Helmholtzzentrum für Schwerionenforschung, Technische Universität Darmstadt, and the Max Planck Institute for Astrophysics. It operates when neutron-rich material is exposed to a high flux of neutrinos. The theoretical proposal, which was recently published in “Physical Review Letters”, may be the solution to a long-standing issue related to the production of a group of rare isotopes present in the solar system but whose origin is still poorly…
A team from UPV participates in developing a new technique that allows studying turbulence in a completely different way from that used in the last 100 years. When we mention turbulence, the first association that springs to mind is often the uncomfortable jostling experienced during airplane travel. However, turbulence encompasses far more than just that; it’s a continuous presence in our daily lives. This term denotes the irregular and chaotic behavior exhibited by fluids, gases, and liquids in a wide…
Using an innovative new method, a University of Saskatchewan (USask) researcher is building tiny pseudo-organs from stem cells to help diagnose and treat Alzheimer’s. Using an innovative new method, a University of Saskatchewan (USask) researcher is building tiny pseudo-organs from stem cells to help diagnose and treat Alzheimer’s. When Dr. Tyler Wenzel (PhD) first came up with the idea of building a miniature brain from stem cells, he never could have predicted how well his creations would work. Now, Wenzel’s…
MHH researchers compared six methods for diagnosing minimal hepatic encephalopathy. Liver cirrhosis often results in a condition known as hepatic encephalopathy (HE). This is a functional disorder of the central nervous system with varying degrees of severity. Experts distinguish between minimal hepatic encephalopathy (mHE) and clinically manifest hepatic encephalopathy, which is associated with personality changes, disorientation and impaired consciousness, including coma. mHE is characterized by impaired mental capacity. These cannot yet be recognized during a physical examination or in conversation,…
HZDR team achieves new energy record for next generation proton accelerators. The Helmholtz-Zentrum Dresden-Rossendorf (HZDR) has made a significant advance in laser plasma acceleration. By employing an innovative method, a research team managed to substantially exceed the previous record for proton acceleration. For the first time, they achieved energies that so far have only seemed possible at much larger facilities. As the research group reported in the journal Nature Physics (DOI: 10.1038/s41567-024-02505-0), promising applications in medicine and materials science have…
Research on centromere structure… Researchers from the Kops group in collaboration with researchers from the University of Edinburgh, made a surprising new discovery in the structure of the centromere, a structure that is involved in ensuring that chromosomes are segregated properly when a cell divides. Mistakes in chromosome segregation can lead to cell death and cancer development. The researchers discovered that the centromere consists of two subdomains. This fundamental finding has important implications for the process of chromosome segregation and provides…
In a recent study published in Nature Physics, researchers from the Hefei Institutes of Physical Science of the Chinese Academy of Sciences, together with researchers of University of Science and Technology of China, have introduced the concept of the “Topological Kerr Effect” by using the low-temperature magnetic field microscopy system and the magnetic force microscopy imaging system supported by the steady-state high magnetic field experimental facility. The study holds great promise for advancing our understanding of topological magnetic structures. Originating in particle physics, skyrmions are unique topological excitations…

LZH and CEC can be found in Hall 3.1 at a shared booth (627). CEC Navigator 2500 – the IBS coating system for large-area substrates and very high productivity. Photo: Cutting Edge Coatings GmbH The…
Conditions on Saturn’s moon Enceladus simulated in the laboratory. In 2018, very large organic molecules were discovered in ice particles on Saturn’s moon Enceladus. It is still unclear whether they indicate the existence of life or were created in some other way. A recent study could help to answer this question. It is possible, that conditions that support or maintain life in extraterrestrial oceans could leave molecular traces in grains of ice. The research on this was conducted at the…
… could lead to surfing a quantum internet. Researchers develop new methods to couple light to sound waves that glide on surfaces. Researchers at the University of Rochester used surface acoustic waves to overcome a significant obstacle in the quest to realize a quantum internet. In a new study published in Nature Communications, scientists from Rochester’s Institute of Optics and Department of Physics and Astronomy describe a technique for pairing particles of light and sound that could be used to faithfully convert information stored in quantum systems—qubits—to optical fields,…
Slow electrons are used in cancer therapy as well as in microelectronics. It is very hard to observe how they behave in solids. But scientists at TU Wien have made this possible. Electrons can behave very differently depending on how much energy they have. Whether you shoot an electron with high or low energy into a solid body determines which effects can be triggered. Electrons with low energy can be responsible for the development of cancer, for example, but conversely…
