“…Since PEG is a good dispersant, it was hypothesized that the nHAP could be coated with PEG due to the low friction coefficient and good hydrophilicity of PEG. 30 In the present results, adding PEG into the scaffold reduced the contact angle and rendered the scaffold hydrophilic. By microscopy, we also found that the extent of nHAP aggregation decreased with increasing PEG content in the scaffolds.…”

“…One of the most promising approaches still remains the adjustment of technological parameters, that is, temperature, pH, stirring rate, etc., of the wet chemical precipitation method to inhibit growth of the crystals . Despite large number of researches dealing with synthesis of nanocrystalline HAp, there are only few reports about HAp precipitation below room temperature.…”

“…Despite large number of researches dealing with synthesis of nanocrystalline HAp, there are only few reports about HAp precipitation below room temperature. There have been some attempts to synthesize calcium phosphates (CaP) at 2°C, 5°C, 10°C, 15°C, and 20°C …”

Nanocrystalline Mg-or Sr-containing hydroxyapatite powders were synthesized through low-temperature chemical precipitation. The most significant factor for reduction in particle sizes included adjusting the reaction temperature between 0°C and 50°C. Syntheses products were characterized using several analytical tools to determine purity and influence of added amount (up to 15 mol%) of Mg or Sr on the composition and structure. Qualitative analysis by Fourier transform infrared spectroscopy and low intensity, broad X-ray diffraction peaks indicated the presence of nanocrystalline and/or amorphous hydroxyapatite in all the products. Moreover, a significant decrease in the crystallinity was observed with increasing Mg (up to 2.8 AE 0.3 wt%) and Sr (up to 9.6 AE 1.0 wt%) concentration. N 2 adsorption and scanning electron microscopy characterizations confirmed the nanocrystalline nature of the synthesized products. The synthesized products had nanosized spherical-like particle morphology with the specific surface area ranging from 89 AE 7 to 150 AE 20 m 2 /g.

“…It can be seen as the concentration of initiator increases the intensity of the peaks decrease, which is a logic consequence of a change in the composition of the particles because of incorporation of the initiator within the particles. As reported by Kumar lower intensity could also be the result of a deficiency of calcium and higher crystalline size [57]. Fig.…”

“…This is contrary to what was observed by Palamivelu et al who reported rod-like structures for particles prepared at pH ¼ 7 while spherical particles were obtained at pH ¼ 9. They assumed it was because of the different ionization of substrates and different ions mobility rates [57].…”
