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 ...
The major printing parameters examined in this study were layer thickness, delay time of spreading the next layer, and build orientation of the specimens. Scaffold dimensional accuracy, porosity, and mechanical stiffness were systematically investigated using a design of experiment approach. Resulting ...
at the nanoscale, was interpreted as indication of the negligible contribution of nanolime-based materials in the consolidation of stones with large porosity. However, the results indicate that in such cases, their effectiveness may be enhanced when used in combination with CaCO3particles, owing to ...

In general, the atomic arrangement of all CaPO4is built up around a network of orthophosphate (PO4) groups, which stabilize the entire structure. Therefore, the majority of CaPO4are sparingly soluble in water (Table1); however, all of them are easily soluble in acids but insoluble in alkali...

The atomic arrangement of calcium orthophosphates is built up around a network of orthophosphate (PO4) groups, which provides stability to the entire structure. The majority of calcium orthophosphates are sparingly soluble in water and insoluble in alkaline solutions, but all of them are easily ...
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 ...
