Effect of thermal annealing on a bilayer polyvinyl alcohol/polyacrylic acid electrospun hydrogel nanofibres loaded with doxorubicin and clarithromycin for a synergism effect against osteosarcoma cells
(Elsevier, 2021-08-02)
Polyvinyl alcohol/polyacrylic acid (PVA/PAA) bilayer hydrogel nanofibres were successfully fabricated by
electrospinning and physically crosslinked via heat treatment. The effects of the thermal annealing
process on the ...
A tough and novel dual-response PAA/P(NiPAAM-co-PEGDMA) IPN hydrogels with ceramics by photopolymerization for consolidation of bone fragments following fracture.
(IOP Science, 2019-07)
In this work, a novel dual-response hydrogel for enhanced bone repair following multiple fractures was investigated. The conventional treatment of multiple bone fracture consists on removing smaller bone fragments from the ...
The influence of mechanical stretching and freeze-thaw processing on the properties of polyvinyl alcohol hydrogels for drug delivery applications
(Athlone Institute of Technology, 2018-04-24)
The study describes the development of physically cross-linked polyvinyl alcohol (PVA) hydrogels using uniaxial orientation via freeze-thawing (F/T). Although cryogels have shown significant improvements in long-term ...
Antimicrobial PAA/PAH electrospun fiber containing green synthesized zinc oxide nanoparticles for wound healing
(MDPI, 2021-05-27)
Wound infections are the main complication when treating skin wounds. This work reports a novel antimicrobial material using green synthesized zinc oxide nanoparticles (ZnONPs) incorporated in polymeric fibers for wound ...
Ti-25Nb-25Ta alloy treated by plasma electrolytic oxidation in phosphoric acid for implant applications
(Rede Latino-Americana de Materiais, 2021)
Among titanium alloys with non-toxic elements, the Ti-25Nb-25Ta alloy has good elastic behavior for applications in osseous implants, biocompatibility, and excellent corrosion resistance. The present study aimed to
better ...
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 ...
Investigation of the effects of orientation on freeze/thawed Polyvinyl alcohol hydrogel properties.
(Elsevier, 2018-12)
Although hydrogels produced via freeze-thawing (F/T) technique have been thoroughly studied in literature, stretching hydrogels in between freeze-thawing cycles could change its properties and might be modulated for drug ...
Development of electrospun PVA nanofibers via freeze-thawing method
(Athlone Institute of Technology, 2019)
The polyvinyl alcohol (PVA) hydrogels are proven to have the benefits of improving water retention ability, cell attachment and controlled drug release in
medical device materials for pharmaceutical applications. Due to ...
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 ...
Titanium-Niobium (Ti-xNb) alloys with high Nb amounts for applications in biomaterials
(Scielo, 2020-11-10)
The present study produced binary titanium-niobium alloys Ti-xNb with high niobium percentage
(x = 50, 80 e 90 wt.%) aiming to apply it as a base material in osseous implant devices. The produced
TiNb alloys presented a ...
