Synovial joint lubrication – does nature teach more effective engineering lubrication strategies?
Nature shows numerous examples of systems which show energy efficiency, elegance in their design and optimum use of materials. Biomimetics is an emerging field of research in engineering and successes have been documented in the diverse fields of robotics, mechanics, materials engineering and many more. To date little biomimetics research has been directed towards tribology in terms of transferring technologies from biological systems into engineering applications. The potential for biomimicry has been recognised in terms of replicating natural lubricants but this system reviews the potential for mimicking the synovial joint as an efficient and durable tribological system for potential engineering systems. The use of materials and the integration of materials technology and fluid/surface interactions are central to the discussion
Toward phonon-boundary engineering in nanoporous materials
Tuning thermal transport in nanostructured materials is a powerful approach
to develop high-efficiency thermoelectric materials. Using a recently developed
approach based on the phonon mean free path dependent Boltzmann transport
equation, we compute the effective thermal conductivity of nanoporous materials
with pores of various shapes and arrangements. We assess the importance of
pore-pore distance in suppressing thermal transport, and identify the pore
arrangement that minimizes the thermal conductivity, composed of a periodic
arrangement of two misaligned rows of triangular pores. Such a configuration
yields a reduction in the thermal conductivity of more than with
respect the simple circular aligned case with the same porosity.Comment: 4 pages, 4 figures, 1 tabl
Polymer reinforcement with nanoparticles
The Polymers and Composites research group belongs to the Materials Science and Engineering and Chemical Engineering Department of the University Carlos III of Madrid, Spain. Its objective is the development and characterization of polymeric materials, focussed in their reinforcement through the dispersion of nanoparticles. Following this method, very small additions of nanoreinforcements usually improve mechanical, electrical and optical properties, as well as the service performance of these materials. The research group is looking for companies interested in applying nanotechnologies to polymers of industrial interest
