“…The results of the elemental analysis from the SEM-EDX characterization in Figure 3 show that the Ca/P value in the hydroxyapatite sample in this study through the calculation of the elemental mass ratio is 1.70. This result is close to the mass ratio of Ca/P hydroxyapatite in natural bone which is 1.67 [17] which gives it superior mechanical properties [18], [19].…”

This research aims to compose nanofibers as a scaffold material in bone tissue engineering in terms of surface morphological properties and porosity. HA nanorod was prepared by the precipitation-ultrasonication method, while the PVA/CS/HA nanofiber composites were made by the electrospinning method using a static collector. HA was characterized by using XRD and SEM-EDX, while the PVA/CS/HA nanofiber composites used FTIR and SEM. The results show that HA nanorod has a crystalline size of 10.86 nm, crystallinity level of 52.38 per cent, and Ca/P ratio of 1.70. From the SEM image shows HA nanorod width of 11.6 nm and 97.53 nm in length and some of it still in the form of HA nanoparticles. The diameter and porosity of PVA/CS/HA nanofiber with addition of 0, 10, 20 per cent HA were 275, 212, 265 nm and 72.94, 69.49, 70.81 per cent, respectively.

Heavy metal contamination of water has become a global environmental burden, which has stirred up agitation worldwide. Fabrication of adsorbents utilizing either low cost, environment friendly materials or waste products can be helpful in remediating environmental pollution. The current study evolved around the synthesis of nanocomposites derived from such raw precursors like spent tea waste biochar, hydroxyapatite, and clays. In this context, two nanocomposites, namely manganese ferrite doped hydroxyapatite/kaolinite/biochar (TK-NC) and manganese ferrite doped hydroxyapatite/vermiculite/biochar (TV-NC), were synthesized followed by their employment for decontamination of heavy metals from aqueous media. TK-NC and TV-NC exhibited the crystallite sizes in the range of 2.55–5.94 nm as obtained by Debye Scherrer Equation and Williamsons–Hall equation The fabricated nanocomposites were characterized using FT-IR, SEM-EDX, and powder XRD. Batch adsorption studies were performed, and influence of different adsorption parameters (contact time, reaction temperature, solution pH, adsorbent dose, and initial adsorbate concentration) on metal adsorption was examined. Thermodynamic studies revealed that the adsorption of Cr(VI), Ni(II) and Cu(II) on TK-NC and TV-NC was endothermic (+ΔH°) and indicates disorderness (+ΔS°) at the solid-liquid interface owing to the strong affinity of metal ions with adsorbent. The heavy metal uptake selectivity followed the following decreasing order; Cr(VI) > Cu(II) > Ni(II) by both nanocomposites, with adsorption capacities falling in the range of 204.68–343.05 mg g-1. Several adsorption kinetic and isotherm models were applied to experimentally calculated data, which suggest favorable adsorption of Cr(VI), Ni(II) and Cu(II) by TK-NC and TV-NC from the system while obeying general-order kinetics and R-P adsorption model, conferring the transition in adsorption kinetics order and involvement of multiple adsorption process.

“…Also, the poor HA mechanical property should be the main reason why there is coating stability. Significant research has been undergone to boost the poor bonding strength of metal / HA interface with the coating technique having effects on the layer reliability, adhesive strength, and stability development on coating methods is thought to be the answer to this issue [318][319][320]. The material properties of reviewed ceramic-based hip implants used for orthopaedic applications are listed in Table 7 below.…”

There is a current need for tissue and organ repairs, replacement, and regeneration for patients who suffer from diseased or damaged tissues or organs. This situation is continuously on the rise and the supply of this form of therapy does not meet the patients demand mostly due to lack of donors and biocompatibility issues which causes immune system rejection of the implants. To succeed through these limitations, researchers are currently investigating the use of scaffolds as another approach for implants. The conventional scaffold fabrication technique is limited due to the precision of pore design. The 3D printing technology on the other side can produce an extracellular matrix with a higher degree of complexity and matching details such as pore size and geometry suitably based on certain factors including tissue engineering, hip biomechanism, material suitability, ethical standards, future, and challenges. This paper in particular focuses on materials challenges and opportunities addressing various issues at various levels to the materials-process-property relationship. It is comprehensive as it starts with hip biomechanism in gait and stress distribution to give the reader a clear perspective of the magnitude of challenges for hip implants and details to consider when designing the materials. This is followed by 3D printing for orthopaedic applications and 3D hip tissue regeneration. The hip replacement materials including polymers, composites, and metals are explored and correlated to conventional hip replacement materials. The work is concluded with some concluding remarks on opportunities, challenges, and future trends. The goal is to have scaffolds that have the capability of having a biomimicking design similar to the extracellular matrix with the advantage being the provision of structural supports for cell attachment, growth, and differentiation with the main goal of producing an operational organ or tissue. The knowledge derived from this review offers huge potential for providing a pathway for sustainable healing.
