The residual compressive stresses mainly originate from the lattice mismatch and the difference of thermal expansion coefficient between the semipolar (1122) AlN and the (1010) m-plane sapphire substrate, which were counteracted by a huge number of tensile stresses generated by the coalescence process of crystal grains during the growth [18].

For the granules freeze-dried, extension of grain boundary and micro-crack were recognized, indicating excellent body fluid permeation and bio-absorption in a living body.
The values of granules freeze-dried were 37-43% (PF-A/ HAp), 75-83% (PF-EC/HAp), and 56-64% (PF-M/HAp), depending on the interface function, such as the number of adsorption site, adsorption strength, and boundary film layer.

The greater the value of SSA shows that grains are also finer.
Samples of fly ash used meets the standards of the three main compounds in which the number is more than 70%, while based on the content of CaO, fly ash Y11,2 is classified as type C fly ash, while the remaining four is type F fly ash.

Smaller average diameter of the PLA/SiO2 fibres was related to bigger differences in the fibres diameter and higher number of agglomerates, which was exhibited by relatively high standard deviation.
In the case of the PLA/TCP fibres apatite grew in the form of small grains surrounding the fibres (Fig. 6).

The research was carried out under the grant number RDU180372 and RDU190147.

The cell lengths were obtained by the linear intercept method, known as the Heyn method [6], which consists in superposing several parallel lines in x and y direction (equally spaced by 0.35 mm) on the micrographs, allowing to determine the number of cell walls intersected by units lengths, NL.

Since the effect of pinning grain boundaries by fine precipitates during recrystallization is necessary for retaining deformation texture, appropriate alloying elements and asymmetric rolling conditions seem to have achieved the retained TD-rotated β-fiber texture even after solution treatment at a high temperature of 813 K.

However, reports show that significant numbers of cement squeeze jobs were found to break down or develop zonal isolation problems after HCl-HF acidizing [5, 6].
Furthermore, the polymeric net occupies voids in the microstructure of hardened cement slurries [8], anchoring the anhydrous cement grains.

Due to advantageous material properties and a fine-grained structure without porosity, formed sheets of magnesium promise to offer better mechanical properties than castings [2].
At first a limited number of points, e.g. within a diameter of 30 mm, was considered by the approximation in favour of increasing the velocity of the calculation.

Pre- and co-incubation with orientin significantly reduced the number of cells labeled by annexin V.
