    Development of an autonomous AI assistant to build nanostructures

    Positioning of individual molecules on the material surface is performed using scanning tunneling microscopy. The tip of the probe emits electrical impulses that deposit molecules carried by the probe. Credit: Bernhard Ramsauer—TU Graz A material’s chemical composition alone may reveal little about its properties. Often the determining factor is the arrangement of molecules within the atomic lattice structure or on…

    Physicists use selenium doping to achieve high selectivity in nanostructures

    Scanning tunneling microscope image of the reaction pathway of mTBPT on a Cu(111) substrate, showing the transition from a random metal-organic structure before selenium doping to a well-ordered, crystalline, two-dimensional metal-organic nanostructure after doping. Credit: Nature Communications (2024). DOI: 10.1038/s41467-024-47614-9 Physicists at the National University of Singapore (NUS) have used flexible precursors and selenium doping to achieve controlled conformations of…
