By careful synthesis of ultrafine layered structures or superlattices, built from layers of lead titanate and strontium titanate, researchers discovered they could create electrical spirals, called polar vortices, similar to the rotating vortices observed in magnetic systems.
Researchers have made a significant step toward breaking the so-called 'color barrier' of light microscopy for biological systems, allowing for much more comprehensive, system-wide labeling and imaging of a greater number of biomolecules in living cells and tissues than is currently attainable.
Scientists demonstrated that a vacancy in graphene can be charged in a controllable way such that electrons can be localized to mimic the electron orbitals of an artificial atom. Importantly, the trapping mechanism is reversible (turned on and off) and the energy levels can be tuned.
Researchers built a fully functional, nanometer-sized transistor by using atomically flat, two-dimensional molybdenum disulfide semiconductor and a single-walled carbon nanotube imbedded in zirconium dioxide.
