Abstract
Annually, a substantial quantity of industrial waste is generated globally, and the build-up of this waste poses a serious risk to society. The generation of carbide lime waste as a byproduct during acetylene gas production in industries has resulted in many environmental issues. This study attempts to convert carbide lime waste into nanohydroxyapatite (nHAp) that can be used to treat patients suffering from orthopaedic injuries. The synthesis of nHAp from carbide lime was carried out by chemical precipitation method using 85 % orthophosphoric acid. The resulting nHAp was physicochemically characterized by different instruments. Fourier Transform Infrared Spectroscopy (FTIR) was used to analyze the functional groups to confirm the conversion of carbide lime. The structural analysis of the synthesized nHAp was done by X-Ray Diffractometer (XRD). Field Emission Scanning Electron Microscopy (FESEM) was used to find the morphology of nHAp particles. The elemental composition of nHAp was studied by Energy Dispersive X-ray Spectroscopy (EDX). The hydrodynamic size of nHAp was calculated by the nano-zeta sizer instrument. Thermo Gravimetric Analyzer (TGA) studied the thermal behaviour of nHAp and carbide lime. Further, mechanical testing was carried out for nHAp using the Vickers microhardness test. In vitro tests, such as biodegradation and cell viability, were also conducted. As a result, the nHAp was found to be biocompatible and biodegradable. In the future, this nHAp biomaterial can be modified for different biomedical applications.
期刊介绍：
Nano-Structures & Nano-Objects is a new journal devoted to all aspects of the synthesis and the properties of this new flourishing domain. The journal is devoted to novel architectures at the nano-level with an emphasis on new synthesis and characterization methods. The journal is focused on the objects rather than on their applications. However, the research for new applications of original nano-structures & nano-objects in various fields such as nano-electronics, energy conversion, catalysis, drug delivery and nano-medicine is also welcome. The scope of Nano-Structures & Nano-Objects involves: -Metal and alloy nanoparticles with complex nanostructures such as shape control, core-shell and dumbells -Oxide nanoparticles and nanostructures, with complex oxide/metal, oxide/surface and oxide /organic interfaces -Inorganic semi-conducting nanoparticles (quantum dots) with an emphasis on new phases, structures, shapes and complexity -Nanostructures involving molecular inorganic species such as nanoparticles of coordination compounds, molecular magnets, spin transition nanoparticles etc. or organic nano-objects, in particular for molecular electronics -Nanostructured materials such as nano-MOFs and nano-zeolites -Hetero-junctions between molecules and nano-objects, between different nano-objects & nanostructures or between nano-objects & nanostructures and surfaces -Methods of characterization specific of the nano size or adapted for the nano size such as X-ray and neutron scattering, light scattering, NMR, Raman, Plasmonics, near field microscopies, various TEM and SEM techniques, magnetic studies, etc .
