Early generation ceramic articulations were problematic in terms of ceramic implant fracture and wear. Although the mechanical properties of ceramic material have improved during the last three decades, ceramic component fracture remains an issue. Many authors have reported fractures of the ceramic head, and a few have described ceramic acetabular insert fracture. However, these complications a...

Oxygen selective membrane based on δ-Bi 2 O 3 /Ag cermet has maximum potential in separating oxygen from air. However, the achieved flow is inferior to high-temperature membrane. The paper proposes a new approach creating smart with layer nanocomposite complex architecture, operating at intermediate temperatures (T op ~550-600 °C). At stage of obtaining nanopowders components, and features mech...
