Surface modification for titanium implants by hydroxyapatite nanocomposite
Background: Titanium (Ti) implants are commonly coated with hydroxyapatite (HA). However, HA has some disadvantages such as brittleness, low tensile strength and fracture toughness. It is desirable to combine the excellent mechanical properties of ZrO2 and the chemical inertness of Al2O3 with respect to the purpose of this project which was coating Ti implants with HA-ZrO2-Al2O3 to modify the s...
متن کاملEngineering Oilseeds for Industry
Over the last century the world has become dependant on fossil fuels as the primary source of hydrocarbons for energy and industry. These resources are finite and non renewable and their exploitation releases massive amounts of carbon dioxide into the atmosphere. The identification of sustainable replacements has been an ongoing area of research for many years. Plant triacylglycerol (TAG) oils ...
متن کاملReview paper: surface modification for bioimplants: the role of laser surface engineering.
Often hard implants undergo detachment from the host tissue due to inadequate biocompatibility and poor osteointegration. Changing surface chemistry and physical topography of the surface influences biocompatibility. At present, the understanding of biocompatibility of both virgin and modified surfaces of bioimplant materials is limited and a great deal of research is being dedicated to this as...
متن کاملA Comparison between β-Cyclodextrin and Chitosan as Soft Organic Materials for Surface Modification of MWCNTs
In this paper, synthesized (raw) multi-walled carbon nanotube (rMWCNTs) surfaces were modified with chitosan and β-cyclodextrin using Chen’s soft cutting technique. Raw and surface modified multi-walled carbon nanotubes were observed by transmission electron microscope (TEM). The results showed that chitosan and β-cyclodextrin could attach to the outer surface of nanotubes, wrapping the nanotub...
