Characterization and potential uses of Hydroxyapatite Nanopowder/Nanoparticle

Hydroxylapatite, also referred to as hydroxyapatite (HA), is a calcium apatite in its naturally occurring mineral form with the formula Ca5(PO4)3(OH). A fluorapatite or chlorapatite may be produced if the OH−ion is replaced by fluoride, chloride or carbonate. Hydroxylapatite crystallizes in the hexagonal crystal pattern. Pure hydroxylapatite powder is of white color. However, naturally occurring apatites can also have brown, yellow, or green hue, resembling the coloration of dental fluorosis.

Hydroxyapatite Nanopowder/Nanoparticle (HApN), nanodots or nanocrystals are spherical or faceted high surface area oxide magnetic nanostructured particles.

Nanoscale Hydroxyapatite Nanopowder/Nanoparticle (HApN) are normally 20-80 nanometers (nm) with specific surface area (SSA) in the 15 - 50 m2/g range but sometimes available with an average particle size of 100 nm range with a specific surface area of approximately 5 - 10 m2/g.

Hydroxyapatite Nanopowder/Nanoparticle (HApN) is widely used as a biocompatible ceramic in many areas of medicine, but due to its bioactivity, and osteoconductive properties and resemblance to mineral bone, Hydroxyapatite Nanopowder/Nanoparticle (HApN) is mainly used as a drug-delivery system for bone therapy applications and contact with bone tissue. Moreover, Hydroxyapatite Nanopowder/Nanoparticle (HApN) has been used as a theranostic probe.

Carbon Nanotube Threads

Since its discovery, carbon nanotube (CNT) has attracted many interests in different technology fields due to its extraordinary properties. Properties such as, high strength, great electrical and thermal conductivity, light weight and flexibility made CNT one of the best materials for wide range of applications. However, from its name it can be understood that CNT is a nanoscale material which is very small to be applied for the production of daily products. Researchers all around the world are working on finding methods and techniques which could produce new materials with the extraordinary properties of CNT. Image retrieved from: https://worldindustrialreporter.com/strong-light-flexible-carbon-nanotubes-threads-with-ultrahigh-conductivity/ One of these research is focusing on the production of high strength threads that can be used in the manufacturing of fabrics, cables and ropes. An international group of scientists were able to produce a flexible conductive thread that i

Multi Walled Carbon Nanotube Dispersions

Carbon nanotubes (CNTs) have attracted enormous attention in recent years due to its unique physical, electronic, optical and potential applications in materials science and nanotechnology. The van der Waals interaction between tubes, however, makes CNTs aggregate in most organic solvents and aqueous solutions, which is the major limitation of their practical applications.Various approaches have been studied to alter the CNT surface to promote the dispersion of individual nanotubes and prevent their reaggregation. On the basis of this widely accepted viewpoint, numerous techniques such as covalent bonding, surfactant coating and polymer wrapping have been developed for surface modification or sidewall functionalization.These methods, however, are complicated, time-consuming and cause permanent damage to the CNT structure and properties of the surface, which produces residues of the dispersion agent for the final product.
