摘要:
A polymer composition, a cross-linked polymer formed therefrom, an electrolyte membrane and electrode for a fuel cell including the same, and a fuel cell employing the electrode and the electrolyte membrane. The cross-linked polymer includes an oxazine-based monomer capable of retaining phosphoric acid and has excellent mechanical strength. When the cross-linked polymer is used, an electrode and electrolyte membrane for a fuel cell with enhanced capability of retaining phosphoric acid at a wide range of temperature may be manufactured, leading to long-term durability, and enhanced proton conductivity.

摘要:
An artificial knee joint comprise a femoral component and tibial component. The posterior side of the femoral component comprises medial and lateral condyles, wherein the width and offset of the posteromedial condyle is greater than the width and offset of the posterolateral condyle. At the posterior the tibial bearing component comprises medial and lateral articulating surface geometries, wherein the posterior slope of the lateral articulating geometry is greater than the posterior slope of the medial articulating geometry. The medial articulating surface geometry of the tibial bearing component supports the medial condyle of the femoral component and the lateral articulating surface geometry of the tibial bearing component supports the lateral condyle of the femoral component. The greater slope of the lateral articulating geometry allows the femoral component condyle to roll down to the posterior during knee flexion. This invention of an artificial knee joint for a prosthetic knee implant system facilitates deep knee flexes beyond 130 degrees.
