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 ... -
Comparison of fused-filament fabrication to direct compression and injection molding in the manufacture of oral tablets.
