Combining Two Ultrathin Materials in a New QD Could Enable Widely Tunable Quantum Systems
A new type of quantum dot (QD) has been developed that allows for more accurate and more widely tunable energy levels of confined electrons. The advance in QD technology combines graphene (a conductive single atomic layer of carbon atoms) and hexagonal boron nitride (h-BN), a single layer of material similar to graphene except that it is insulating.

Imaging System Navigates Fog Better Than Human Vision
In what could be a boon for autonomous vehicle technology, a system has been developed that can produce images of objects enveloped in fog too thick for human vision to penetrate. Under actual fog conditions, researchers estimate the system could provide visibility of between 30 and 50 m.

New Lens Provides Nanometer-Scale Resolution
New Lens Provides Nanometer-Scale Resolution
A multilayer pair of materials, tungsten carbide and silicon carbide, was used to prepare high-efficiency, high-numerical aperture (NA) multilayer Laue lenses (MLLs). In a series of studies, researchers used a pair of MLLs to achieve a 2D focus of 8.4 × 6.8 nm at a photon energy of 16.3 keV. They demonstrated scanning-based imaging of samples with a resolution below 10 nm.
