Yttria/ceria stabilized zirconia composites: evaluation of microstructural, mec...
Faria, Diana Marisa Monteiro; Henriques, Bruno Alexandre Pacheco de Castro; Carvalho, Óscar Samuel Novais; Silva, Filipe Samuel; Mesquita-Guimarães, J.[Excerpt] 3-mol% Yttria-Stabilized Tetragonal Zirconia Polycrystal (3Y-TZP), a ceramic biomaterial, has been widely used in the dentistry field due to its biocompatibility, tooth-like color and mechanical properties [1]. Despite these advantages, its physical and mechanical properties tend to degrade as a result of a low-temperature aging process induced by its sensitivity to low-temperature degradation (LTD) w...
In-vitro mechanical and biological evaluation of novel zirconia reinforced biog...
Gouveia, Paula F.; Mesquita-Guimarães, J.; Galárraga-Vinueza, María E.; Souza, Júlio C. M.; Silva, Filipe Samuel; Fredel, Márcio C.; Boccaccini, Aldo R.Bone defects resulting from infections, tumors, or traumas represent a major health care issue. Tissue engineering has been working togehter with medicine to develop techniques to repair bone damage and increase patient's life quality. In that context, scaffolds composed of bioactive ceramics have been explored, although their poor mechanical properties restrain their clinical applications as highly porous stru...
Cell adhesion evaluation of laser-sintered HAp and 45S5 bioactive glass coating...
Mesquita-Guimarães, J.; Detsch, R.; Souza, A. C.; Henriques, B.; Silva, F. S.; Boccaccini, A. R.; Carvalho, O.Laser texturing is a technique that has been increasingly explored for the surface modification of several materials on different applications. Laser texturing can be combined with conventional coating techniques to functionalize surfaces with bioactive properties, stimulating cell differentiation and adhesion. This study focuses on the cell adhesion of laser-sintered coatings of hydroxyapatite (HAp) and 45S5 b...
The potential use of oyster shell waste in new value-added by-product
H. Silva, Thamyres; Mesquita-Guimarães, J.; Henriques, Bruno; Silva, Filipe Samuel; Fredel, Márcio C.Calcium carbonate is one of the most used raw materials in various industries, such as construction materials, food supplement, pharmaceutics, animal feed, plastic production, and others. Calcium carbonate can derive from marine wastes, like crustaceans and bivalve’s shells. The worldwide demand for new sources of food has increased exponentially, and following that tendency, the mariculture—especially the oyst...
