Silicon nitride (Si(3)N(4)) is an industrial ceramic used in spinal fusion and maxillofacial reconstruction. Maximizing bone formation and minimizing bacterial infection are desirable attributes in orthopedic implants designed to adhere to living bone. This study has compared these attributes of Si(3)N(4) implants with implants made from two other orthopedic biomaterials, i.e. poly(ether ether ...

This paper presents a study of hole quality and energy consumption in the process of drilling a thermoplastic polymeric material, polyether-ether-ketone, reinforced with 30% glass fibers (PEEK-GF30). PEEK-GF30's capacity to be machined has focused on turning operations. Studies of drilling involving thermoplastic polymeric materials have considered materials with other types of matrices, or rei...

STUDY DESIGN An in vitro study examining factors produced by human mesenchymal stem cells on spine implant materials. OBJECTIVE The aim of this study was to examine whether the inflammatory microenvironment generated by cells on titanium-aluminum-vanadium (Ti-alloy, TiAlV) surfaces is affected by surface microtexture and whether it differs from that generated on poly-ether-ether-ketone (PEEK)...

In this work, antistatic, high-performance composites of poly (ether ether ketone) (PEEK) and concentrations 0.5–7 vol% expanded graphite (EG) were fabricated via twin-screw extrusion injection moulding at mould temperatures 200°C. The morphological, electrical, rheological, thermal, mechanical, wear properties the investigated. Scanning electron microscope (SEM) images indicate that distributi...

Abstract The substantial heat generation due to miniaturization and high-degree integration of electronic devices is one the major issues facilitate efficient thermal management in power electronics. Though epoxy-based composites have shown great interest different applications such as laminated circuit board, component encapsulations, potting, they low application temperature (up 150 °C) highe...
