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 ...

Nanotribology of copper clusters
Nanotechnologies in Russia, 2016The use of nanotechnologies in tribology has led to a large number of marketable lubricants containing nanoparticles with unproven efficiency. Tribological and physicochemical studies of some lubricant additives aimed at determining the tribological characteristics are presented in this work. It is found that applying metal particles (copper, above all)

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, 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 ...

Nanotribological Properties of UHMWPE/Quartz Composites
Materials Science Forum, 2005Wear of ultra-high molecular weight polyethylene (UHMWPE) and its composites is one of the main obstacles that limit the longevity of total joint replacements. Compression molded UHMWPE/quartz composites with organosiloxane as a cross-linking agent for UHMWPE matrix, were tested in nanoindentation and nanowear.

Nanotribology, Nanomechanics and Materials Characterization
2007Nanotribology and nanomechanics studies are needed to develop a fundamental understanding of interfacial phenomena on a small scale, and to study interfacial phenomena in micro/nanoelectromechanical systems (MEMS /NEMS ), magnetic storage devices, and many other applications. Friction and wear of lightly loaded micro/nanocomponents are highly dependent

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.

Nanotribology in Electrolytic Environments
1997To get a fundamental knowledge about forces acting at surfaces it is necessary to perform measurements under conditions that are as defined as possible. Measurements in an electrochemical cell provide such a condition with the additional benefit that external parameters like the surface potential or the electrolyte composition can be varied.

Micro-/Nano- electromechanical systems (MEMS/NEMS) are future devices that have a spectrum of applications ranging from rocket technology to biological sciences. Although MEMS devices are known for over two decades, very few categories of them are used in commercially applications due to their poor reliability.
