Processing of ZrO2 scaffolds coated by glass-ceramic derived from 45S5 bioglass
(Elsevier, 2016-02)
Three dimensional, highly porous, ZrO2 scaffolds coated by glass-ceramic derived from 45S5 bioglass were fabricated. The surface reactivity of 45S5 in aqueous solution was investigated as a function of the immersion time. ...
Processing, structural, and biological evaluations of zirconia scaffolds coated by fluorapatite
(Wiley Blackwell Publishing, Inc, 2018-11)
Highly porous zirconia (ZrO2) scaffolds fabricated by the replication method were coated with fluorapatite (FA). The FA coating was obtained by dipping the ZrO2 scaffolds into stabilized aqueous FA slips having different ...
Surface modification using the biomimetic method in alumina-zirconia porous ceramics obtained by the replica method
(Wiley-Blackwell, 2018-10-01)
The modification of biomaterials approved by the Food and Drug Administration could be an alternative to reduce the period of use in humans. Porous bioceramics are widely used as support structures for bone formation and ...

Procesamiento de andamios 3D de fosfato tricálcico (β- TCP)/ZrO2-biovidrio de fosfato para aplicaciones de regeneración ósea
(Universidad Michoacana de San Nicolás de Hidalgo, 2017-06)
Bone tissue engineering is an excellent alternative to reduce bone disorders and conditions, by bone regeneration from the combination of biomaterials and cell therapy. In the research project, the scaffolds were fabricated ...
Síntesis y caracterización de óxidos nanoestructurados de cerio modificados con praseodimio para ser aplicados en pilas de combustible de óxido sólido
(Universidad Pedagógica y Tecnológica de ColombiaFacultad de Ciencias. Escuela de Posgrados. Maestría en Química, 2017)
The properties of cerium dioxide are due to the fluorite crystal structure, which guarantees the mobility of oxygen ions and electrons on the surface and inside the material. In addition, the modification of cerium cations ...
Síntesis y caracterización de nanoestructuras de Co3O4 dopadas con Ni para aplicación en detección de gases
