Following a theoretical study on the retardation effect ofsecond phase particles on grain boundary sliding[Acrametalf. J&275(1983)], we haveconducted internal friction experiments in Cu-Fe and Cu-SiO,. The relaxation peaks produced by the grain boundary sliding are reduced by the a-Fe or SiO, partic
The dependence of the internal friction and Young's modulus on the oxygen deficiency in the superconductor YBa: Cu 3 07\_ ~ was studied at frequencies near 2. 7 kHz. Peaks observed near 110 and 230 K decreased with decreasing oxygen stoichiometry in a sample with the orthorhombic structure, and were
## Abstract Bioactive glasses react chemically with body fluids in a manner that is compatible with the repair processes of the tissues. This results in the formation of an interfacial bond between the glasses and living tissue. Bioactive glasses also stimulate boneβcell proliferation. This behavio
