Sientists have developed a new micropatterning approach for OLEDs on silicon substrates. This might eliminate the use of color filters and shadow masks in the future and allow full-color displays to be developed by means of a new process.
Biophysicists report on the first successful outcome in the targeted dynamic positioning of nerve cells on a chip. The proven surface acoustic wave technology now opens up new ways of understanding and influencing neuronal networks.
Topology is a global aspect of materials, leading to fundamental new properties for compounds with large relativistic effects. The incorporation of heavy elements give rise to non-trivial topological phases of matter, such as topological insulators, Dirac and Weyl semimetals.
The study, which has yielded a provisional patent, establishes a method for wicking chemically compatible vegetable oils into the surfaces of common extruded plastics, like those used for ketchup packets and other condiments.
Using scanning tunnelling microscopy (STM), extremely high resolution imaging of the molecule-covered surface structures of silver nanoparticles is possible, even down to the recognition of individual parts of the molecules protecting the surface.
