“…When increasing the calcination temperature from 900 °C to 1100 °C, the intensity of diffraction peaks increased. At the calcining samples, there are three major plane appeared at (300), (211), and (112) at 2 theta near 32.9°, 32.2°, and 31.8°, similar conclusions were found by [13]. The HAp crystalline composition has chemical reaction Ca 10 (PO 4 ) 6 (OH) 2 and like HAp pattern (ICDD 00-024-0033), and the values of lattice parameter c and a can be estimated by this experience as presented in Table 1.…”

“…Hammood et al [12] used the bovine femur bone to synthesize natural hydroxyapatite, and the results show the optimal calcination temperature to obtain near to pure hydroxyapatite at 900 °C. Hammood et al [13] studied the comparison of nano-synthetically produced and natural HAp powder, and the results present that, the biowaste materials which calcined at 950 °C could produce micro-hydroxyapatite that was nearly like the commercial nano-hydroxyapatite.…”

Hydroxyapatite is one of the most common bio-ceramic materials which is currently used in the biomedical field. The development of hydroxyapatite is due to their crystallographic and chemical similarity to the hard tissue of human body. The present study aims to prepare hydroxyapatite from a bio-waste material (carp fish bone) as an ecofriendly and inexpensive source by calcination treatment. The calcination process was applied at various calcining temperatures; the heating rate was kept constant at 10 °C min −1. FTIR results proved the formation of hydroxyapatite at 950 °C due to the founding peaks corresponding to phosphate (632 cm −1) and hydroxyl (3572 cm −1). XRD analysis confirmed the formation of HAp at 950 °C by the presence three main peaks: (211), (112), and (300), which correspond to the characteristic peaks of hydroxyapatite. Raman analyses which displayed the calcining process remove organic components from a bones matrix. AFM showed that the size of particles is ranged between nano and microns. EDS analysis found that the Ca/P reaches 1.6589 for fish bone after calcination at 950 °C, which is close to stoichiometric HAp (1.67).

“…The low intensity peak around 630-660 cm −1 is attributed to the stretching vibration of O-H groups. 49 Based on this spectrum, it could be well evidenced that, the peaks corresponding to HAP were found which supports for the formation of crab shells (calcium source in the formation of HAP)-derived HAP. The characteristic peaks at 2981 cm −1 and 1460cm −1 for the pure PVP exhibits the presence of −CH 2 and −CH Figure 1A.…”

The present investigation focuses on the synthesis of crabshell-derived hydroxyapatite (CS-HAP)/ water-soluble synthetic polymer-polyvinylpyrrolidone(PVP)/ aloevera(AV)-a natural biopolymer, as a composite for enhanced mechanical, antibacterial and biocompatible properties. The reinforcement of polymer has a significant function in increasing the mechanical property of the composite, whereas the incorporation of AV improves the antibacterial and biocompatibility. Phase composition, morphology, mechanical property, and hydrophilicity of CS-HAP/PVP/ AV biocomposite with different concentrations of PVP and AV were examined by Fourier transform infrared spectroscopy (FTIR), X-Ray diffraction (XRD), scanning electron microscopy with energy dispersive X-ray (SEM-EDX), Vickers microhardness tests, contact angle, respectively. Furthermore, the antibacterial efficiency of the composite is assessed using Escherichia coli (E coli) and Staphylococcus aureus (S aureus). The biocompatibility of HOS MG 63 cells on the CS-HAP/PVP/ AV composite is evaluated by MTT assay test. The obtained results evidence that the as-synthesized composite have appropriate mechanical, antibacterial and biocompatible properties. Overall, the combination of mechanical property of PVP, antibacterial and biocompatible property of AV in CS-HAP/PVP/AV, makes the composite a potential therapeutic material for various biomedical applications.

Biological waste holds a major portion of the municipal waste stream, particularly in rural areas of developing countries. According to the Food and Agriculture Organization of the United Nations (FAO), every year there are 1.3 billion tons of food waste produced and around one-third of all food produced for human consumption are being wasted. 1 Amongst the other sources, the livestock industry (fish and poultry industry) has a vital contribution. Some biological
