Scientists are working to understand how those nanoscale defects, when subject to extreme electric fields, evolve into material failures. Those failures turn insulators, which do not conduct electricity, into materials that allow some current to flow.
Researchers have successfully created chiral nanostructures from particles of gold. The trick was to use circularly polarized light to generate electric fields, which localize differently depending on LCP or RCP. This in turn drove the chiral deposition of a dielectric material.
In a new study, researchers describe an innovative DNA walker, capable of rapidly traversing a prepared track. Rather than slow, tentative steps across a surface, the DNA acrobat cartwheels head over heels, covering ground 10- to 100-fold faster than previous devices.
In the wake of its recent discovery of a flat form of gallium, an international team has created another two-dimensional material that the researchers said could be a game changer for solar fuel generation.
