Autor: Felipe Zanette da Silveira, Márcio Antônio Fiori, Tiago Elias Allievi Frizon, Luiz Fernando Belchior Ribeiro, Gustavo Lopes Colpani, Humberto Gracher Riella
Publikováno v: Materials Research, Vol 27 (2024)
The work evaluated the nucleating effect of nanometric zirconia (Zr-NP), obtained by the green sol-gel synthesis route using Euclea natalensis root extract as a reductant, in the low-density polyethylene (LDPE). The Zr-NP was characterized with x-ray

Chemical resistance of core-shell particles (PS/PMMA) polymerized by seeded suspension
Autor: Luiz Fernando Belchior Ribeiro, Odinei Hess Gonçalves, Cintia Marangoni, Günter Motz, Ricardo Antonio Francisco Machado
Publikováno v: Polímeros, Vol 27, Iss 3, Pp 225-229 (2017)
Abstract Core-shell particles were produced on seeded suspension polymerization by using polystyrene (PS) as polymer core, or seed, and methyl methacrylate (MMA) as the shell forming monomer. Two synthesis routes were evaluated by varying the PS seed

Polyimide as carbon and ceramic polysilazane precursors to obtain high carbon content ceramic for high-temperature applications
Autor: Emanoelle Diz Acosta, Ricardo Antonio Francisco Machado, Maira Debarba Mallmann, Fernando J. Da Costa, André V. B. Andrade, Luiz Fernando Belchior Ribeiro
Publikováno v: FRACTURE AND DAMAGE MECHANICS: Theory, Simulation and Experiment.
In this work, a new pathway to obtain high-carbon content ceramic for high-temperature applications was developed. Within this method, polyimide (PI) was used as the carbon source and polysilazane (ML33) as the preceramic polymer using different rati

UHMWPE/HA biocomposite compatibilized by organophilic montmorillonite: An evaluation of the mechanical-tribological properties and its hemocompatibility and performance in simulated blood fluid
Autor: Guilherme Colla, Everton Rafael Breitenbach, Humberto Gracher Riella, Domingos Lusitâneo Pier Macuvele, Márcio Antônio Fiori, Luismar Marques Porto, Karina Cesca, Cíntia Soares, Luiz Fernando Belchior Ribeiro, César Edil da Costa, Janaína Nones
Publikováno v: Materials scienceengineering. C, Materials for biological applications. 100
The low interaction between ultra high molecular weight polyethylene (UHMWPE) and hydroxyapatite (HA) has been one of the problems that results in a composite material with low mechanical and tribological performance due to the formation of agglomera
