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 ...
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, ...
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 ...
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 ...
Tailoring surface properties from nanotubes and anodic layers of titanium for biomedical applications.
(Woodhead Publishing, 2019)
The following chapter gives an overview of the anodic layers and nanotubes produced with plasma electrolytic oxidation. An introduction into the mechanisms involved in producing these nanofilms, such as the required ...
