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 ...
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 ...
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 ...
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 ...
Yerba mate extract in microfibrillated cellulose and corn starch films as a potential wound healing bandage
(MDPI, 2020-11-27)
Microfibrillated cellulose films have been gathering considerable attention due to their high
mechanical properties and cheap cost. Additionally, it is possible to include compounds within the
fibrillated structure in ...
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 ...
Microfibrillated cellulose films containing chitosan and tannic acid for wound healing applications
(Springer, 2021-06-12)
The effectiveness of tannic acid as antimicrobial and wound healing for burns have been shown for a century; however, uncontrolled target dosage may result in undesirable side-effects. Remarkably, tannic acid polyphenols ...
Characterization of gels and films produced from Pinhão seed coat nanocellulose as a potential use for wound healing dressings and screening of Its compounds towards antitumour effects
(MDPI, 2022-07-07)
The reuse of agro-industrial waste assumes great importance today. Pinhão is the seed of
Araucaria angustifolia, which is native to the mountains of southern Brazil, Paraguay, and Argentina.
The coat is a by-product of ...
Titanium-niobium alloys covered by electrospinning technique to applications in bone implants
(Athlone Institute of Technology, 2019)
Recently, to avoid toxic metals in the human environment, there are many efforts to produce alloys containing titanium Ti and niobium Nb. Nb is a powerful stabilizer of
beta-titanium phase[1]. Depending on the composition ...
