Researchers at Columbia University report that they have achieved plasmonically active graphene with record-high charge density without an external gate. They accomplished this by exploiting novel interlayer charge transfer with a two-dimensional (2D) electron-acceptor known as α-RuCl3. α-RuCl3 is unique among nanomaterials because it has an exceptionally high work function even when it is exfoliated down to a one- or few-atom-thick 2D layers.

Researchers at Penn State are beginning to understand the behavior of so-called "active" particles, which, if controlled, has potential implications for smart 3D printing and engineered drug delivery systems. The particles – which can be biological but, in this case, are cylindrical platinum-gold nanorods smaller than a red blood cell – flow in a fluid through a micro-channel into a tapered nozzle. Once collected there, they can be used in additive manufacturing to 3D-print objects or to deliver therapeutics directly to cells.

Researchers at Drexel University have developed antennas that are so thin they can be sprayed into place and robust enough they can provide a strong signal at bandwidths that will be used by fifth-generation (5G) mobile devices. The new antennas, which are made from a two-dimensional material called MXene, are already performing nearly as well as the copper antennas found in most mobile devices on the market today, but with the benefit of being just a fraction of their thickness and weight.

Researchers at the University of Texas at Austin have created the smallest memory device yet, shrinking the cross section area down to just a single square nanometer. In the process, the researchers figured out the physics dynamic that unlocks dense memory storage capabilities for these tiny devices. Defects, or holes in the material, provide the key to unlocking the high-density memory storage capability.

Researchers at the University of California Santa Cruz have achieved the first direct visualization of quantum dots in bilayer graphene, revealing the shape of the quantum wave function of the trapped electrons. This work provides information needed to develop quantum devices based on this system.
