Nickel foils with nano-size grains were produced by electrodeposition using a sulfamate-based
electrolyte. The pH of the electrolyte was varied within the 2.8 to 5.1 range. The crystallite …

Polymer nanocomposites operate in applications where fluid and grease lubricants fail, and
have superior tribological performance to traditional polymer composites. Nanoparticle …

Mammalian grinding dentitions are composed of four major tissues that wear differentially,
creating coarse surfaces for pulverizing tough plants and liberating nutrients. Although such …

… beebei to other members of the genus Colostethus, one aspect of this phylogenetic problem
was partially resolved by a molecular phylogenetic study (GR Bourne, D. W Weisrock, W …

A composite coating of polytetrafluoroethylene and epoxy shows 100 × improvements in wear
resistance as compared to either of its constituents alone and reduced friction coefficient …

Once recombination is halted between the X and Y chromosomes, sex chromosomes begin
to differentiate and transition to heteromorphism. While there is a remarkable variation …

Metal fiber brushes are of interest in many high current density applications due to their high
conductivity and low wear rates in humid environments. The frictional properties and wear …

Measured friction coefficients of carbon nanotubes vary widely from μ < 0.1–μ > 1.0 [ 1 – 6 ],
while theoretical studies suggest intrinsically high friction coefficients, approaching unity [ 7 ]. …

The use of copper–beryllium (UNS C17200) was demonstrated as a low wear, highly
compliant material for the construction of high current density metal fiber brushes. Testing was …
