The production of a novel poly(vinyl alcohol) hydrogel cryogenic spheres for immediate release using a droplet system.
(IOP Science, 2019-06-05)Although freeze-thaw mechanism for producing crosslinked hydrogels is relatively easy and simple, it lacks sufficient integrity and support leading to modifications on its three-dimensional polymeric network arrangement ... -
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 ... -
Electrospun hydrogels composites for bone tissue engineering.
(Woodhead Publishing, 2019)Electrospinning is one of the foremost nanotechnology applications to fabricate bone tissue engineering scaffolds with sizes in the nanometer range. It is regarded as a versatile, inexpensive, and relatively simple methodology ... -
Micro-injection moulding of poly(vinylpyrrolidone-vinyl acetate) binary and ternary amorphous solid dispersions.
(MDPI, 2019-05)Micro-injection moulding (µIM) was used for the production of enteric tablets of plasticised and unplasticised solid dispersions of poly(vinylpyrrolidone-vinyl acetate) (PVPVA), and the effect of the mechanical and thermal ... -

(2007-12-20)Provided is an oriented polymeric sheet comprising a photochromic-dichroic material, wherein the sheet exhibits dichroism in an activated state. Also provided is a multilayer composite comprising at least a support layer ... -
Composite cryogels for dual drug delivery and enhanced mechanical properties.
(Wiley, 2018-04)In this study, we present a simple and effective process that integrates hydrogels with drugs + ceramics via physical crosslinks resulting in improved mechanical properties. These cryogels have the potential for controlled ... -
Extraction method plays critical role in antibacterial activity of propolis loaded hydrogels.
(Elsevier, 2016-03)Extracted propolis has been used for a long time as a remedy. However, if the release rate of propolis is not controlled, the efficacy is reduced. To overcome this issue, extracted propolis was added to a cryogel system. ... -
