Hydroxyapatite, is a naturally occurring mineral form of calcium apatite with the formula Ca 5 (PO 4 ) 3 (OH). Pure hydroxyapatite powder is white. Naturally occurring apatites can, however, also have brown, yellow, or green colorations, comparable to the discolorations of dental fluorosis. Hydroxyapatite Nanopowder/Nanoparticles (50 nm, 99.95+%)  has been widely used as a biocompatible ceramic in many areas of medicine, but mainly for contact with bone tissue, due to its resemblance to mineral bone. In mammals, the skeleton presents a carbonated and partially substituted apatite, based on nanocrystal aggregates, and associated with collagen, building up 3-D structures present in various bone tissue conformations like trabecular or cancellous bone. There has been growing interest in developing bioactive synthetic ceramics that could closely mimic natural apatite characteristics. As mentioned before,  Hydroxyapatite Nanopowder/Nanoparticle  is the main inorganic con...

Graphene  is an allotrope of carbon that exists as a two-dimensional planar sheet. Graphene is technically a non-metal but is often referred to as a quasi-metal due to its properties being like that of a semi-conducting metal. As such, Graphene has many unique properties that cannot be found with other non-metallic materials. In Graphene the carbon–carbon bond length is about 0.142 nanometers.  Graphene sheets  stack to form graphite with an interplanar spacing of 0.335 nm. Graphene is the strongest material ever tested in the world, with an intrinsic tensile strength of 130.5 GPa and a Young's modulus of 1 TPa (150000000 psi). In addition to having a unique strength,  Graphene  is also very lightweight (0.77 mgm-2). Of course with these strong mechanical properties,  Graphene  is one of the most important chemicals that is  researched. Let's look at some studies doing by taking into account of Graphene's extraordinary properties. The adh...
