Nano-hydroxyapatite

Scientifically, the term ultrafine powder or ultrafine particles is used to describe solid products in which the particle sizes are no greater than 100 nm. The ultrafine white carbon black to be discussed in this chapter is the product of particles of a smaller size than those in common products, i.e., ultrafine here is not a scientific but a commercial term. The ultrafine powders in the scientific sense, e.g., nano copper, nano TiO and nano hydroxyapatite, and related topics will be discussed in later chapters. Nevertheless, the principles involved in the preparation of ultrafine white carbon black by impinging stream reaction-precipitation are very similar to those involved in the preparation of the nano powders mentioned above. Therefore this topic is discussed here under the overall title Preparation of ultrafine powders . [Pg.269]

An instrumental characterization of nano-hydroxyapatite was provided by Chen et al. (2002) the size of their particles was ca. 20-30 nm in width and 50-60 nm in length, with a specific surface area of 73 m /g aggregation was avoided with the use of n-butanol. The uniform dispersion of these particles in chitosan solutions was recognized as an important motif for the innovative preparation of chitosan composites in fact, nano-hydroxyapatite + chitosan composite membranes prepared by solvent casting and evaporation were found suitable for guided bone regeneration. [Pg.228]

In the short lapse of a few years, the research works on bone regeneration with the aid of bone cements have become more refined in terms of the effects of novel chitosan scaffolds on the cells involved in the healing process. The use of nano-hydroxyapatite as well as other inorganics in conjunction with variously modified chitosans is greatly contributing to the advancement of chitosan composites for bone healing. [Pg.234]

DSC measurements showed an increase in the ciystalhzahon temperature of polyamide-66 in the presence of nano-hydroxyapatite, but also, decrease in crystallinity with the addition of n-HA to the PA-66 matrix. This was attributed to the hydrogen bonding between the n-HA surface and polyamide-66 molecules. Hydrogen bonding increased... [Pg.134]
