Fig. 1 Ultra-precision polishing of orthopaedic implant Implant designs imitate the natural joint through bearing surfaces made from biomedical materials which have direct contact causing friction between the two surfaces under lubricated conditions which generates particulate wear.
An investigation using a multi-directional pin-on-plate testing machine was used to compare the wear performance of a superpolished material compared to that of a manually polished combination of the same materials.
Many thanks are also due to Zeeko Ltd. for the technical support and Universal Photonics for providing polishing materials for conducting the research work.

In this work composite materials, based on quartz fibers posts and adhesive resins, were employed with the aim to restore damaged teeth.
Their transparency meet the need of modern aesthetic dentistry, allowing repairs in the frontal teeth and the replacing of the metal materials.
A catastrophic brittle pull-out fracture was found for both materials.

Introduction Electrospinning is a plain and wide process for fabrication of an ultrafine fiber from various materials which include polymer, composite and ceramic.
The most preferred fiber/material in various applications is a fiber with a diameter within 10– 1000 nm in scale and soft surface morphology.
