Nanotribology of polymer blends
Journal of Applied Physics, 2000We investigated rheological and tribological properties of polystyrene (PS) and poly (vinyl methyl ether) blends by atomic force microscopy. Glass transition temperature measurements showed that the blends whose PS contents were 80% (PS80) and 60% (PS60) were in the glassy state and in the glass-rubber transition state at room temperature, respectively.

Nanotribology and the Stability of Nanostructures
Japanese Journal of Applied Physics, 1993Atomic scale energetics, structure, and formation mechanisms of solid and liquid junctions occurring between a solid metal tip and a clean metal surface or between the tip and a liquid film of hexadecane molecules adsorbed on a solid surface, are investigated using large-scale molecular dynamics simulations.

Nanotribology, nanomechanics and nanomaterials characterization
Philosophical Transactions of the Royal Society A: Mathematical, Physical and Engineering Sciences, 2007Nanotribology and nanomechanics studies are needed to develop fundamental understanding of interfacial phenomena on a small scale and to study interfacial phenomena in magnetic storage devices, nanotechnology and other applications. Friction and wear of lightly loaded micro/nanocomponents are highly dependent on the surface interactions (a few atomic ...

Nanotribology: Nonlinear Mechanisms of Friction
2014Friction with its related nonlinear dynamics is a vast interdisciplinary field, involving complex physical processes over a wide range of length and time scales. The accelerated progress in experimental and computational techniques, often leading to complex detailed dynamical patterns, has vigorously stimulated the search and implementation of ...

Nanotribology and nanomechanics in nano/biotechnology
Philosophical Transactions of the Royal Society A: Mathematical, Physical and Engineering Sciences, 2008Owing to larger surface area in micro/nanoelectromechanical systems (MEMS/NEMS), surface forces such as adhesion, friction, and meniscus and viscous drag forces become large when compared with inertial and electromagnetic forces. There is a need to develop lubricants and identify lubrication methods that are suitable for MEMS/NEMS. For BioMEMS/BioNEMS,

Surface Forces Apparatus in Nanotribology
2007The Surface Forces Apparatus (SFA) has proven to be an excellent tool for research in nanotribology. It allows the study of single or multiple asperity contacts lubricated or not. The normal load, the contact area and the sliding velocity between the surfaces can be controlled and unambiguously measured with higher accuracy than in any conventional ...

Spiders can produce cobwebs with high strength to density ratio and surprisingly display self-cleaning, strong and releasable adhesion (as geckos). Nanointerlocking, capillary and van der Waals forces, all potential adhesive mechanisms, were thus discussed, demonstrating the key role played by hierarchy to the design of super-hydrophobic, i.e.

Micro- and Nanotribology of Graphene
2014Graphene is a two-dimensional layer of carbon atoms bound by covalent Open image in new window -bonds. It is the building block of graphite, in which the graphene layers are stacked and held together by van der Waals forces.

Nanotribology has been an active field of research for well over a decade. In evolved in response to the search for better understanding of some of the many elusive tribological phenomena, such as friction and solid lubrication. It evolved rapidly, in constant step with the development of new instrument capabilities, which enabled closer and closer ...
