Desenvolvimento e caracterização de biocompósitos de blendas TPU/PCL com hidroxiapatita para produção de scaffolds bioativos via impressão 3D
(Universidade Federal de São Carlos, 2022-08-02)
The increasing need for biological tissues to treat defects caused by disease or injury has demanded new solutions to provide functional substitutes that supply tissue shortages and suit the needs of each patient. In this ...
Synthesis and characterization of Biosilicate/F18 bioglass scaffolds for dental application
(Universidade Federal de São Carlos, 2019-10-16)
In this work, Biosilicate scaffolds were synthesized using the foam replica technique. Biosilicate is highly bioactive, biodegradable, antibacterial, and non-toxic. Despite of these properties, Biosilicate scaffolds present ...

(Universidade Federal de São Carlos, 2021-08-04)
Epoxy/glass fiber composites (GRE) were produced by filament winding with a view to application as a liner in a carbon steel tube to replace all-metal super duplex stainless steel column in offshore petroleum exploration. ...
Influência da incorporação de poli(ácido lático) - PLA, de pó de madeira e outros aditivos no comportamento físico-mecânico do poli(hidroxibutirato) - PHB.
(Universidade Federal de São Carlos, 2004-04-30)
Polymeric materials are used today in the most varied sectors and the deleterious effects of their application, particularly in the short-term, have led to increasing environmental concern. On the other hand, innovative ...
Estudo da transição de fase sólido-vapor e da eficiência de inibidores voláteis de corrosão quando incorporados em matrizes poliméricas
(Universidade Federal de São Carlos, 2005-08-05)
In this work it is proposed a potential barrier model between solid and vapor phases. As a consequence of this model it is developed a method to measure vapor pressure as low as 10-5 Pa. A thermodynamic system consisting ...
Estratégias para a síntese de compósitos moleculares derivados de poliuretanas
(Universidade Federal de São Carlos, 2009-02-20)
In this work, we investigated strategies to obtain polyurethanebased molecular composites containing metal oxide nanoparticles chemically attached to polyurethane polymeric chain. In Strategy 1, nanoparticles functionalized ...
