“…Sonochemical methods allow the synthesis of uniform particles with nanosized products resulting from the chemical reaction that occurs in the presence of ultrasonic radiation [84]. Utara and Klinkaewnarong [84] synthesized nanometric HAp through a sonochemical process (20 kHz) at 25 °C and different irradiation times, followed by calcination at 600 °C. They observed that the smaller diameter (nanorods 8 nm) resulted from an ultrasonic irradiation time of 20 min for a Ca/P ratio of 1.5.…”

“…According to the method, reagents and variables adopted, it is possible to obtain materials based on CaP with different phases, which results in materials with diverse characteristics and properties, such as crystalline defects, high surface area, organic material affinity found in physiological medium and so on [46]. HAp can be synthesized by a variety of techniques that can be broadly grouped into six sets of methods: i) dry methods: involve solid state and mechanochemical reactions [63][64][65][66][67]; ii) wet methods: based on low-temperature chemical precipitation [68], co-precipitation [66,69,70], sol-gel route [71][72][73][74][75][76] and hydrolysis [77,78]; iii) hydrothermal methods: use aqueous solutions of high temperature and high voltage, as hydrothermal [79][80][81], emulsion and microemulsion [82,83], and sonochemical [84]; iv) high temperature processes: include combustion [85,86] and pyrolysis [87,88]; v) synthesis based on biogenic sources: can be extracted from fish bones [89], shells [90], eggshells [91,92], bovine bones [93,94], in the presence of biomolecules [95][96][97] or biomembranes [98]; and vi) combination of the aforementioned methods. All methods used for synthesizing HAp particles have different processing characteristics and can result ...…”

Hydroxyapatite (HAp) is a bioceramic widely studied due to its chemical similarity with the mineral component of bones. Besides, it is biocompatible, bioactive and thermodynamically stable in the body fluid what poses it as an attractive material for a wide range of applications in the biomedical field. Several efforts have been focused on the synthesis of particles of this material aiming to the precise control of size and morphology, porosity and surface area. HAp is widely used as an implant for bone tissue regeneration, as a coating for metallic implants and in a drug-controlled release. In this sense, the objective of this review is to gather information related to HAp, providing readers with information about synthesis methods, material characteristics and their applications.

“…Given the wide range of applications, synthesis of nanocrystalline HAp has gained significant importance over the last decade. To achieve the formation of nanosized HAp crystals variety of approaches have been implemented, including biomimetic synthesis, that is, in situ synthesis in the presence of various organic matrixes such as gelatin, natural rubber latex, chitosan, polycaprolactone, etc. Conversely, it has been reported that HAp with very high SSA could be obtained through application of self‐assembling surfactants (eg, cetyltrimethylammonium bromide, etc.)…”

Low‐temperature synthesis of nanocrystalline hydroxyapatite: Effect of Mg and Sr content

2017

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.

“…The utilization of templating strategies enables the formation of porous nanostructures by overcoming the tendency of close packing by solid‐state structures . Nano‐hydroxyapatite was successfully synthesized through the usage of natural rubber latex as templating material and nano‐rod–like particles with a small diameter (8 nm) was reported . The fabrication of core‐shell nanoparticles was also reported by Soule et al who synthesized Ag–Au nano‐shell core based on mesoporous silica shell through a sol‐gel template.…”

Synthesis and Characterization of NiO Nano‐Spheres by Templating on Chitosan as a Green Precursor

In this study, nickel oxide was prepared through the calcination of extrusion dripped chitosan/nickel nitrate beads. The morphology and structural properties of the products were studied using various characterization techniques. Uniformly distributed nickel oxide was formed as observed from the studies of surface morphology where the processing parameters play a huge role on the resulting morphology. TEM results have shown that nickel oxide with crystallite sizes of 10–30 nm was obtained. The Fourier-transform infrared spectra studies show an intense peak at 525 cm−1, which is attributed to the vibration of Ni–O bond. Furthermore, the XRD results show NiO diffraction peaks correspond to (111), (200), (220), (311), and (222) which indicates that a bunsenite structure with a face-centered cubic phase was produced in this study. The usage of 500°C as the lower limit in this study is justified due to the complete removal of the templating material as seen in the thermalgravimetric analysis studies. Furthermore, it was obtained that the largest surface area of nickel oxide synthesized using this technique is 48.024 m2/g with pore sizes of 19.843 nm. The usage of chitosan as a green template for the synthesis of nanoparticles has shown promising results which allows a more economical and sustainable approach for the fabrication of nanomaterials
