Mar 26, 2024 (Nanowerk News) “New computational models give us new research opportunities. Extending thermodynamics for ultrashort excitations will provide novel insights into how materials function on the nanoscale,” says Matthias Geilhufe, Assistant Professor at the Department of Physics at Chalmers University of Technology. Entropy is a measure of irreversibility...
Tiniest ‘starquake’ ever detected
Mar 26, 2024 (Nanowerk News) An orange dwarf star has yielded the tiniest ‘starquakes’ ever recorded, measured by an international team of scientists. Named Epsilon Indi, the star is the smallest and coolest dwarf star yet observed with solar-like oscillations – “starquakes” like those shown by the Sun. These oscillations...
Elusive 3D printed nanoparticles could lead to new shapeshifting materials
Mar 25, 2024 (Nanowerk News) In nanomaterials, shape is destiny. That is, the geometry of the particle in the material defines the physical characteristics of the resulting material. “A crystal made of nano-ball bearings will arrange themselves differently than a crystal made of nano-dice and these arrangements will produce very...
A more effective particle conversion surfaces for space instruments
Mar 25, 2024 (Nanowerk News) Southwest Research Institute is investing internal funding to develop more effective conversion surfaces to allow future spacecraft instruments to collect and analyze low-energy particles. Conversion surfaces are ultra-smooth, ultra-thin surfaces covering a silicon wafer that convert neutral atoms into ions to more effectively detect particles...
Research team develops important building block for artificial cells
Mar 25, 2024 (Nanowerk News) During cell division, a ring forms around the cell equator, which contracts to divide the cell into two daughter cells. Together with researchers from Heidelberg, Dresden, Tübingen and Harvard, Professor Jan Kierfeld and Lukas Weise from the Department of Physics at TU Dortmund University have...
Scientists 3D print luminescent quantum dot-polymer architectures with potential for advanced optoelectronics
Mar 25, 2024 (Nanowerk Spotlight) Quantum dots, nanoscale semiconductors with unique light-emitting properties, have garnered excitement for years due to their potential to revolutionize technologies from solar cells to biomedical imaging. In particular, quantum dots made of organic-inorganic hybrid perovskite materials exhibit exceptional properties like color tunability, narrow emission bands,...
Novel electrochemical sensor detects dangerous bacteria
Mar 25, 2024 (Nanowerk News) Each year, bacterial infections claim several million lives worldwide. That is why detecting harmful microorganisms is crucial – not only in the diagnosis of diseases but also, for example, in food production. However, the methods available so far are often time-consuming, require expensive equipment or...
A self-cleaning wall paint made with nanoparticles
Mar 25, 2024 (Nanowerk News) Typically, beautiful white wall paint does not stay beautiful and white forever. Often, various substances from the air accumulate on its surface. This can be a desired effect because it makes the air cleaner for a while – but over time, the colour changes and...
Researchers develop new single-molecule transistor that uses quantum interference
Mar 25, 2024 (Nanowerk News) An international team of researchers from Queen Mary University of London, the University of Oxford, Lancaster University, and the University of Waterloo have developed a new single-molecule transistor that uses quantum interference to control the flow of electrons. The transistor, which is described in a...
Why scientists are turning telescope data into sounds
Mar 25, 2024 (Nanowerk News) Images from telescopes like the James Webb Space Telescope have expanded the way we see space. But what if you can’t see? Can stars be turned into sounds instead? In this guest editorial, NASA scientists and science communicators Dr Kimberly Arcand and Megan Watzke explain...
