As an example, the layer-by-layer methodology was used to build up nanostructured hybrid coatings by sequential deposition of bioactive glass-ceramic nanoparticles, exhibiting a negatively charged surface, and chitosan, a positively charged macromolecule (Couto et al., 2009). Such biodegradable ...

At lowQthe curves flatten, this knee is indicating a tendency to a Guinier regime64, related to the distribution of sizes and shapes of scattering objects. As observed in other multiscale systems, such as sintered ceramics, cements and rocks58,60,73, it likely connects two domains. One, ou...

The main constituents of human bones are CaPO4(~60–70 wt%), collagen (~20–30 wt%) and water (up to 10 wt%) (Bocchi and Valdre1993; Skinner2005; Daculsi et al.1997). An interesting cautionary tale on the knowledge development about the structurally incorporated water in bone apatite...

For example, addition of Ag+ [347, 348], Zn2+ and Cu2+ [348] has been used for imparting antimicrobial effects, while radioactive isotopes of 90Y [349], 153Sm [350-352] and 186Re [350] have been incorporated into HA bioceramics and injected into knee joints to treat rheumatoid ...
It often occurs at a relatively lower compression pressure, for instance, at 20 MPa where a knee point appears, as shown in Figure 9. The densification is primarily due to the rearrangement of the powder particles, as finer particles penetrate into the voids between the larger ones resulting ...
