Nanosuspension of pinhão seed coat development for a new high-functional cereal bar.
(Wiley, 2020-03-31)The seeds from Araucaria angustifolia—commonly named as pinhão—are important culturally, and viable regional food from Brazil. Although now considered an endangered species, methods to increase the awareness of this tree ... -
Mass-customization of oral tablets via the combination of 3D printing and injection molding.
(Elsevier, 2019-10-05)The new frontier of medicine is the personalization of treatment to match a patient’s individual needs. Fused-filament fabrication (FFF) offers a platform for the personalization of drug dosage forms, but one of its chief ... -
Effect of unidirectional freezing using a thermal camera on polyvinyl (alchohol) for aligned porous cyrogels.
(Taylor & Francis Online, 2020-03-18)Unidirectional freeze casting for polymers and ceramics has been performed extensively; however, the mechanisms involved in unidirectional freezing are not thoroughly understood and therefore, in this study, polyvinyl ... -
Freeze-thaw electrospun PVA-Dacarbazine nanoparticles: preparation, characterization and anticancer evalution.
(Taylor & Francis Online, 2019-06-13)Dacarbazine (DTIC) is an antitumor agent that has limited clinical applications due to its insolubility, instability and toxicity to normal cells. One possibility to achieve controlled release is PVA-based NPs. This work ... -
Oxide layer containing apatite formed on Ti-25Nb-25Ta alloy treated by two-step plasma electrolytic oxidation.
(Elsevier, 2020-01-25)Hydroxyapatite (HA) is a bioactive calcium phosphate capable of enhancing the implant/bone connection improving osteoconductivity and osseointegration process. However, the HA presents mechanical properties limiting its ... -
