“…The PO4 3stretching bands in bovine and caprine bone samples appear at wavelength 1018 and 1010 cm -1 respectively (Malla et al, 2020). The characteristic bands for CO3 2were assigned at 1446, 1409, 872 cm -1 for both bovine and caprine samples.…”

“…Also, the Amide I and Amide II bands were 1640 and 1543 cm -1 in bovine, and 1636 and 1543 cm -1 in caprine sample respectively, the Amide peaks could be attributed to the presence of protein (Collagen) macromolecules in the raw bones (Al-Sokanee et al, 2009, Bano et al, 2017. The hydroxyl (OH -) band (3568 cm −1 ) was absent in both samples; this may be attributed to the overlapping of impurity bands over the OHband (Malla et al, 2020). Some of the functional groups bands in the two bone samples appeared in the same wavelength while others were in very close wavelength, Table 2.…”

Studies have been carried out on bovine bone due to its abundance and large quantity of hydroxyapatite (HAP) in it while caprine bone has been understudied. In this study, locally sourced bovine and caprine bones were washed in distilled water, defatted at 120°C for 1.5 hr in a pressure pot, ball-milled, sieved to 150 µm particle size and characterised. The X-ray fluorescence (XRF) and Energy dispersive X-Ray Spectroscopy (EDS) analysis revealed calcium, phosphorus and carbon as the main components. Both bones contained carbon and oxygen due to the presence of organic collagen but the quantity in caprine bone was a bit higher as revealed by the Fourier Transform Infrared Spectroscopy (FTIR) and EDS spectra. A slight difference in thermal decomposition patterns was recorded while X-Ray diffraction analysis (XRD) revealed the presence of identical functional phases. The microstructures showed needle-like and pebble-like shapes for bovine and caprine respectively, also on visual examination of the Scanning Electron Micrograph (SEM), the bovine samples tended to have particle surface roughness more than caprine. Consequently, the chemical properties of both bone raw samples were insignificantly different from each other except for collagen composition and morphology.

A greener improvement was achieved for the synthesis of diverse N,N-dibenzylated compounds from the reaction of various aromatic amines with benzyl bromide using the ultrasound irradiation in solvent- and catalyst-free conditions. The dibenzylation reactions were carried out in different solvents and solvent-free conditions under ultrasound irradiation at various temperatures. The yields were very low in all applied solvents, while in the solvent-free condition and at room temperature, the yields were excellent. Due to obtaining the high reaction yields, the catalyst was not used.

Hydroxyapatites (HAps) synthesized from waste animal bones have recently gained attention due to their outstanding properties. This is because there is a need to fabricate scaffolds with desirable mechanical strength, ability to withstand high temperatures, and insoluble in solvents such as water, acetone, ethanol, and isopropyl alcohol. This study is an extensive summary of many articles on the routes of synthesis/preparation of HAp, and the optimum processing parameter, and the biomedical application areas, such as: drug administration, dental implants, bone tissue engineering, orthopedic implant coatings, and tissue regeneration/wound healing. A broad catalog of the synthesis methods (and combination methods), temperature/time, shape/size, and the calcium‐to‐phosphorous (Ca/P) value of diverse waste animal bone sources were reported. The alkaline hydrolysis method is proposed to be suitable for synthesizing HAp from natural sources due to the technique's ability to produce intrinsic HAp. The method is also preferred to the calcination method owing to the phase transformation that takes place at high temperatures during calcinations. However, calcinations aid in removing impurities and germs during heating at high temperatures. When compared to calcination technique, alkaline hydrolysis method results in crystalline HAp; the higher degree of crystallinity is disadvantageous to HAp bioactivity. In addition, the standardization and removal of impurities and contaminants, thorough biocompatibility to ensure clinical safety of the HAp to the human body, and improvement of the mechanical strength and toughness to match specific requirements for the various biomedical applications are the important areas for future studies.
