A technical paper titled “Dynamically tuning friction at the graphene interface using the field effect” was published by researchers at University of Illinois Urbana-Champaign and University of ...

Graphene is the most well-known member of the 2D materials family. It consists of a sheet of covalently bonded carbon atoms in a hexagonal lattice with the thickness of a single atom. This unique ...

Multi-layered graphene is a promising carbon-based nanomaterial for a variety of next-generation technologies, but the relationships between its surface structures and properties are not entirely ...

Chemists and physicists shed light on a crucial aspect of friction: how things begin to slide. Using fluorescence microscopy and dedicated fluorescent molecules, they are able to pinpoint how and when ...

A major advantage of atomic force microscopes (AFMs) is their versatility in integrating various operational modes that assess different material properties and functionalities. Among the most ...

Irregularities present on a surface are often described as surface roughness or texture. These surface textures such as grooves and dimples impart friction, which is the force between two sliding ...

Force spectroscopy relies on the precise measurement of forces acting on a probe as it interacts with a sample. The key principles of force spectroscopy include: AFM-based force spectroscopy is the ...

Graphene, which consists of a single layer of carbon atoms, is the poster child of carbon-based 2D nanomaterials. It has many attractive properties that could be exploited in next-generation ...

March 9, 2022 — According to research released by Pusan National University in South Korea, multi-layered graphene is a promising carbon-based nanomaterial for a variety of next-generation ...
