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 ...
Structure response for cellulose-based hydrogels via characterization techniques.
(Springer, 2019)
Hydrogels are three-dimensional crosslinked polymeric networks capable of imbibing substantial amounts of water or biological fluids and are widely used in biomedical applications, especially in pharmaceutical industry as ...
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 ...
Scratch-resistant and well-adhered nanotube arrays produced via anodizing process on β-titanium alloy
(Elsevier, 2021-03)
Well-adhered nanotube arrays were produced through the anodizing technique on a Ti-25Nb-25Ta alloy and tribo-mechanically evaluated by nanoindentation and nanoscratch tests. Disregarding substrate effects, the hardness of ...
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 ...
Preparation and characterization of novel poly(vinyl) (alcohol) (PVA) and poly(acrylic acid) (PAA) hydrogels for sensitive hydrogels.
(Sciforum, 2014-05)
Stimuli Sensitive hydrogels have enormous potential in various applications. Various
environmental variables are found in the body, such as low pH and elevated temperatures. For this
reason, either pH-sensitive and/or ...
Electrospinning of hydrogels for biomedical applications
(Springer Nature, 2018)
The field of biomedical applications for hydrogels requires the development of nanostructures with specific controlled diameter and mechanical properties. Nanofibers are ideally candidates for these advanced requirements, ...
Self-photopolymerizable hydrogel-ceramic composites with scavenger properties
(MDPI, 2022-03-21)
The photocatalytic behaviours of semiconductive ceramic nanoparticles such as TiO2, ZnO, Fe2O3, and Fe3O4, have been extensively studied in photocatalysis and photopolymerization, due to their ability to produce radical ...
