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.

Cadmium Sulfide Nanopowder and Its Applications

Cadmium sulfide is the inorganic compound with the formula CdS. Cadmium sulfide is a yellow solid. It occurs in nature with two different crystal structures as the rare minerals greenockite and hawleyite. As a compound that is easy to isolate and purify, cadmium sulfide the principal source of cadmium for all commercial applications. Its vivid yellow color led to its adoption as a pigment for the yellow paint "cadmium yellow" in the 18th century. Cadmium Sulfide Nano Powder, CdS (99.9+%, 20 nm)  shows unique physical, chemical and structural properties from the bulk. The melting point, electronic absorption spectra, band gap energy crystal structure, and other properties of cadmium sulfide nanoparticles are affected by size. Thus, cadmium sulfide on the whole is an attractive system for practicing synthetic chemistry for nanocrystals and for understanding the chemistry, growth history of nanomaterials and also for various technical applications. Colloidal dispersions of ...

Carbon Nanotubes Doped with Graphene Nanopowder and Applications

Carbon nanotubes and graphene are different forms of carbon atom based materials. They have different properties and can be used in various applications. But what happens if we use them as a hybrid structure? The excellent mechanical, physical, and chemical properties of low-dimensional carbon materials like graphene and carbon nanotube have enabled them as promising building blocks for three-dimensional nanoarchitectures. In this regard, extensive interests have been attracted to synthesize graphene and carbon nanotube hybrid structures. Earlier works suggested that  Carbon Nanotubes Doped with Graphene Nanopowder (52 wt% Graphene )  is a promising solution for quick energy dissipation, which could enhance interface thermal conductivity of the ‘building blocks’ for future nanoscale mechanical and electrical devices. In the electricity perspective, it is found that ‘CNT pillared-graphene’ system would extend the excellent electrical conductivity of graphene and nanotube to ...
