…can detect minute differences between similar foods and discern instances of food safety concerns.” The electronic tongue comprises a graphene-based ion-sensitive field-effect transistor, or a conductive device that can detect…
…and electronic properties of the bilayer structures can be fundamentally altered by twisting their crystal lattices against each other. A well-studied example of this is graphene, a special form of…
…like graphite that is made up of layers of carbon atoms that can be exfoliated down into sheets of graphene that are one atom thick. Graphene is a critical component…
…than remaining fully submerged. This affects both the proteins’ structural stability and the ability to illuminate their detailed structure. To overcome this challenge, Lander’s group developed a thin graphene-coated grid…
…gold, and palladium, deposited on an atomically thin support—graphene. We used graphene as a sort of hob for this process to heat the particles, and as they melted, their atoms…
…Effects and Light Transformation Molybdenum diselenide also has additional advantages. Like graphene, it is a layered material, but unlike graphene, it behaves as a semiconductor. It also exhibits nonlinear optical…
…a very tiny amount of hexagonal boron nitride (h-BN) particles, two-dimensional cousins to carbon-based graphene, suspended in standard mineral oils are highly efficient at removing heat from a system. “We…
…In previous research, scientists had accomplished the feat of making a monolayer of graphene — a substance similar to the graphite found in pencil leads. “The technique these researchers used…
…structures including carbon nanotubes. Another famous carbon nanomaterial — a one-atom-thick sheet called graphene — followed shortly after. After buckyballs, scientists wondered if other elements might form these odd hollow…
…Structures Ultra-thin materials, which consist only of one or a few atomic layers are currently a hot topic in materials science today. Research on two-dimensional materials started with graphene, a…
…exposed edge and have potential for a variety of energy-oriented applications. The Rice research appears in the journal Advanced Materials. Molybdenum disulfide isn’t quite as flat as graphene, the atom-thick…
…tungsten disulfide (WS2), which belongs to a class of 2-D crystals known as transition metal dichalcogenides (TMDs). Like the single-layer carbon material called graphene, TMDs form thin films with a…
Researchers find half-light, half-matter particles in atomically thin semiconductors made of a 2D layer of molybdenum and sulfur atoms arranged like graphene. Credit: City College of New York A newly…
