Friction on Au(100) surfaces has been studied by atomic force microscopy under electrochemical control. Atomic-scale stick–slip pattern in the lateral force signal reveal changes in the surface structure upon changing electrochemical potential, in particular between the hexagonal reconstruction and the Au(100)-(1×1) structure. Friction on Au(100) is higher on its (1×1) structure than on its hexagonal...
Friction and wear of single layers of graphene have been studied at the micrometer scale. Epitaxial graphene grown by thermal decomposition on SiC-6H(0001) is found to have an initial friction coefficient of 0.02, significantly lower than graphite under the same experimental conditions. During reciprocal sliding the graphene layer is damaged. The evolving friction coefficient of 0.08 for the carbon-rich...
Distributed Virtual Environments such as Massive Multiplayer Online Games or Virtual Worlds have become very popular in the last few years and a more substantial surge in popularity and use is expected. Because of the huge number of users most of these environments have to cope with scalability problems. The change of the basic infrastructure from a centralized client-server to a decentralized peer-to-peer...
