Nanolubricants

Product Description
The technology involved in lubrication by nanoparticles is a rapidly developing scientific area and one that has been watched with interest for the past ten years. Nanolubrication offers a solution to many problems associated with traditional lubricants that contain sulphur and phosphorus; and though for some time the production of nanoparticles was restricted by the technologies available, today synthesis methods have been improved to such a level that it is possible to produce large quantities relatively cheaply and efficiently.

Nanolubricants develops a new concept of lubrication, based on these nanoparticles, and along with the authors’ own research it synthesises the information available on the topic of nanolubrication from existing literature and presents it in a concise form. 

• Describes the many advantages and potential applications of nanotechnology in the tribological field.
• Offers a full review of the state-of-the-art as well as much original research that is yet unpublished.
• Includes sections on boundary lubrication by colloïdal systems, nanolubricants made of metal dichalcogenides, carbon-based nanolubricants, overbased detergent salts, nanolubricants made of metals and boron-based solid nanolubricants and lubrication additives.
• Authored by highly regarded experts in the field with contributions from leading international academics.

Nanolubricants will appeal to postgraduate students, academics and researchers in mechanical engineering, chemical engineering and materials science. It should also be of interest to practising engineers with petroleum companies and mechanical manufacturers.

Mechanics of Boron Nitride Nanotubes: A Continuum Theory Based on the Interatomic Potential

Product Description
Boron nitride nanotubes display unique properties and have many potential applications. An atomistic-based continuum theory is developed for boron nitride nanotubes. The continuum constitutive model for boron nitride nanotubes is obtained directly from the interatomic potential for boron and nitrogen. Such an approach involves no additional fitting parameters beyond those introduced in the interatomic potential. The atomistic-based continuum theory is then applied to study the elastic modulus, stress-strain curve and nonlinear bifurcation in boron nitride nanotubes. An analytic approach is then established to determine the tensile and bending rigidity of a hexagonal boron nitride (h-BN) monolayer and single- and multi-wall boron nitride nanotubes directly from the interatomic potential. Such an approach enables one to bypass atomistic simulations and to give the tensile and bending rigidity in terms of the parameters in the potential. The thickness of h-BN monolayer is also discussed.A hybrid atomistic/continuum model based on the interatomic potential for boron nitride is also developed to study the Stone-Wales transformation in boron nitride nanotubes under tension.
