By using plasmons to “wiggle” a free electron in a sheet of graphene, researchers have developed a new method for generating X-rays. In this image of one of their simulations, the color and height represent the intensity of radiation (with blue the lowest intensity and red the highest), at a moment in time just after an electron (grey sphere) moving close to the surface generates a pulse.

A new way to make X-rays

MIT researchers have found a phenomenon that might lead to more compact, tunable X-ray devices made of graphene.

Researchers created pores in a graphene sheet (in purple) and then placed it over a layer of silicon nitride (in blue) that had been punctured by an ion beam. This allows specific hydrated ions, which are surrounded by a shell of water molecules, to pass through.

Big range of behaviors for tiny graphene pores

Like biological channels, graphene pores are selective for certain types of ions.

An uncoated copper condenser tube (top left) is shown next to a similar tube coated with graphene (top right). When exposed to water vapor at 100 degrees Celsius, the uncoated tube produces an inefficient water film (bottom left), while the coated shows the more desirable dropwise condensation (bottom right).

Researchers have shown that a DC voltage applied to layers of graphene and boron nitride can be used to control light emission from a nearby atom. In these figures, graphene is represented by a maroon-colored top layer; boron nitride is represented by yellow-green lattices below the graphene; and the atom is represented by a grey circle. An applied DC voltage can drastically modify the graphene la...

In a two-step process, engineers have successfully sealed leaks in graphene. First, the team fabricated graphene on a copper surface (top left) — a process that can create intrinsic defects in graphene, shown as cracks on the surface. After lifting the graphene and depositing it on a porous surface (top right), the transfer creates further holes and tears. In a first step (bottom left), the team...

Shown here is the crystal structure of molybdenum disulfide, MoS2, with molybdenum atoms shown in blue and sulfur atoms in yellow. When hit with a burst of laser light, freed electrons and holes combine to form combinations called trions, consisting of two electrons and one hole, and represented here by orange and green balls.
