“…35,36 This band is absent in the Raman spectrum of β-TCP. 29,37 Another obvious difference compared to β-TCP is that the signal corresponding to the ν 1 mode in the Raman spectrum of β-TCP is usually observed as a doublet; 29,34 however, in our case, we can see only a single peak. Possibly, this spectral change can be caused by the low crystallinity of our prepared WH powders since the synthesis was performed at low temperature.…”

“…All these bands are also present in the Raman spectra of β-TCP and associated with internal vibrations of PO 4 3– ions .

“…A previously reported Raman spectrum of terrestrial WH exhibited a strong and well-resolved doublet of the ν 1 band . On the other hand, in ion-substituted β-TCP, this band can also be observed as a singlet . Similarly, like in the FTIR spectra, there is no significant difference in relative intensity of observed bands depending on the chemical composition of the samples; particularly, the relative intensity of the band at 920 cm –1 does not change depending on the Ca-to-Zn ratio.…”

In the present work, a series of zinc whitlockite (Ca x Zn y (HPO 4 ) 2 (PO 4 ) 12 ) powders was synthesized by a low-temperature dissolution–precipitation process for the first time. The phase conversion from calcium hydroxyapatite to zinc whitlockite occurred in an acidic medium in the presence of Zn 2+ ions. Variable chemical composition of the synthesis products was achieved by changing Ca-to-Zn molar ratio in the reaction mixture. Investigation of the phase evolution as a function of time demonstrated that phase-pure zinc whitlockite powders can be synthesized in just 3 h. It is also demonstrated that single-phase products can be obtained when the Ca-to-Zn ratio in the reaction medium is in the range from 9 to 30. With higher or lower ratios, neighboring crystal phases such as scholzite or calcium hydroxyapatite were obtained. The morphology of the synthesized powders was found to be dependent on the chemical composition, transforming from hexagonal to rhombohedral plates with the increase of Zn content. Thermal stability studies revealed that the synthesized compounds were thermally unstable and decomposed upon heat treatment.

“…Finally, the largest grains ranging from 1.4 to 5 µm were observed for the 0.5STO-0.5BMO sample. It is known that impurity phases in comparison with major phases can possess a completely different morphology and can be often observed in the grain boundary region [41]. In our case, for samples with a minor Mn 3 O 4 phase (Figure 5c,d), we cannot see the formation of particles with obviously different shapes or sizes.…”

In this study, the aqueous sol-gel method was employed for the synthesis of (1−x)SrTiO3-xBiMnO3 solid solutions. Powder X-ray diffraction analysis confirmed the formation of single-phase perovskites with a cubic structure up to x = 0.3. A further increase of the BiMnO3 content led to the formation of a negligible amount of neighboring Mn3O4 impurity, along with the major perovskite phase. Infrared (FT-IR) analysis of the synthesized specimens showed gradual spectral change associated with the superposition effect of Mn-O and Ti-O bond lengths. By introducing BiMnO3 into the SrTiO3 crystal structure, the size of the grains increased drastically, which was confirmed by means of scanning electron microscopy. Magnetization studies revealed that all solid solutions containing the BiMnO3 component can be characterized as paramagnetic materials. It was observed that magnetization values clearly correlate with the chemical composition of powders, and the gradual increase of the BiMnO3 content resulted in noticeably higher magnetization values.

Diverse applications of nanoparticles (NP) have been revolutionary for various industrial sectors worldwide. In particular, magnetic nanoparticles (MNP) have gained great interest because of their applications in specialized medical areas. This review starts with a brief overview of the magnetic behavior of MNP and a short description of their most used synthesis methods. The second part is dedicated to the MNP applications in tissue engineering, emphasizing the calcium phosphate‐based NP with intrinsic magnetic properties, recently highlighted in the literature as alternative and viable solutions for bone regeneration. The challenges associated with the controversial long‐term toxicity effects of MNP can be overcome using this new generation of multifunctional bone‐like magnetic materials. Furthermore, the influence of magnetic field parameters, such as modality of application, intensity, and spatial distribution, on the biological behavior of magnetic materials, especially for bone repair, is shown. The last part of the review presents the current state of the art regarding the development of magnetic biomaterials for additive manufacturing (AM), aiming to fabricate scaffolds by AM technologies, focusing on bone tissue engineering applications.
