Mastering the intricacies of controlling matter at the nanoscale level is part of a revolutionary quest to apply nanotechnology to benefit industrial processes. A key element of that technology is the use of carbon nanotubes. […]
Nature provides three sources of energy for free: sunlight, air and gravity. Solar and wind power are increasingly exploited, gravity less so. Hydraulic power plants harvest energy from flowing rivers. Tidal energy can be gathered […]
WASHINGTON (May 17, 2017)—A new study examining how ice forms from pure water found that the geometry of the surface that water is on can have an effect on whether or not it freezes, suggesting […]
Atomic force microscopy (AFM) is an extremely sensitive technique that allows us to image materials and/or characterize their physical properties on the atomic scale by sensing the force above material surfaces using a precisely controlled […]
Triboelectric nanogenerators convert mechanical energy harvested from the environment to electricity for powering small devices such as sensors or for recharging consumer electronics. Now, researchers have harnessed these devices to improve the charging of molecules […]
Controlling friction is one of the main goals in modern tribology. Due to complexity of the tribological processes, up to date the problem remains mainly unsolved. While classical tribology relies on the famous friction laws, […]
Graphene, a wonder just one atom thick material, shows incredible wear-resistance and super low friction levels. This behavior is ascribed to its low inter-layer shear properties and high normal load carrying capabilities. However, in many […]
Graphene is a unique material in many aspects and has recently been applied in various ways. In tribology, it has been shown to lead to a superlubricity – an ultra low friction state. In laboratory […]
2D materials are single or only few atomic layer thick and posses unique properties with potential in many technological fields. They are highly anisotropic, having significantly different properties in-plane and perpendicular-to-the-plane. For example, graphene, […]
Superlubricity, a state of low friction (<0.001), can be achieved by different mechanisms. The structural superlubricity occurs, if the crystal lattices of the contacting bodies are incommensurate. Nano-scrolls may act as a bearing and may […]
