• Abstract

  Bioglasses represent a very promising class of biomaterials for the repair of bone tissue damage, due to their biocompatibility, bioactivity and osteoconductivity. They can be synthesized by two methods: melting and quenching and by Sol-Gel. The Sol-Gel is more versatile, allowing to prepare, in addition to monoliths, particles and porous structures called scaffolds, which have interconne…

• Abstract

  The 45S5 bioglass® is one the most promising materials to be used in bone tissue damages, especially due to its biocompatibility, bioactivity and osteoinduction. However, the production of BG 45S5 scaffolds with a good compromise between porosity and mechanical properties results in crystallization of the glass because of its small sintering window, lowering the properties that make it su…

• Abstract

  In this project is proposed to modify the surface of Bioglass 45S5 with calcium ions employing ion exchange method and short duration heat treatment. By using these procedures are expected to change the chemical composition and microstructural properties of glass surface. Previous studies on surface modification of 45S5 Bioglass has demonstrated an acceleration of the kinetics of formatio…

• Abstract

  The most practical way to repair a bone defect of any size and in any part of the body would be through its replacement with a material which is chemically and morphologically similar to the bone matrix and which stimulates the new tissue growth while it is being degraded. In this context, calcium phosphate cements are excellent candidates, once, besides of being resorbable, they can be m…

• Abstract

  Graphene is a sheet of carbon with one atom thickness, but it possesses an incredible number of unique electronic, mechanical, and photonic properties, as well as being incredibly strong. The traditional process for the synthesis of graphene involves several steps, which increases the cost of production, but also uses hazardous materials as reducing agents or solvents such as hydrazine, w…
