To overcome this challenge, the researchers from the Institute for Integrated Cell - Material Sciences (iCeMS) at Kyoto University borrowed a principle from polymer chemistry and developed it into a technique to assemble graphene into porous 3D architectures while preventing stacking between the sheets.

When a graphene lattice or sheet is formed, its polycrystalline structure has random boundaries between the single - crystal grains.

Two examples: graphene — single - atom - thick sheets of carbon atoms — has unique mechanical, electrical, and optical properties; and two - dimensional electron gases (2DEG)-- planar collections of electrons supported at the interface between certain semiconductors such as gallium arsenide — allow the observation of such emergent behaviors as the quantum Hall effect and the spin Hall effect.

Scientists formed these crystals — which occur at room temperature — by squeezing tiny amounts of water between two sheets of graphene, planes of carbon a single atom thick.

In the journal Optical Materials Express, from The Optical Society (OSA), the researchers reported that graphene oxide sheets treated with brief exposure to bright light in the form of a camera flash exhibited reversible bending at angles from zero to 85 degrees in response to switching the relative humidity between 33 and 86 percent.

Cross thinks that if he can control the way the ribbons form and stack, he might be able to use them as transistors (electrical switches), capacitors (devices that store electrical charge) or connections between electrically conductive graphene sheets.

They demonstrated that a sheet of graphene, a lattice of carbon atoms one layer thick, could be used to differentiate between bases in a strand of DNA by poking a tiny hole in the sheet and threading DNA through it.

The top row shows the build - up of bacteria (green) on a plain sheet of polyimide (left), graphite (middle), and laser - induced graphene (right), while the bottom shows the clear split between plain polyimide and electrified LIG (Credit: Arnusch Lab / Ben - Gurion University of the Negev)

Dresselhaus studied intercalated two - dimensional graphene sheets and provided important insights into the properties of not only 2D graphene, but also of the rich interactions between graphene and the surrounding materials.
