Anion induced gelation in polyvinyl alcohol: a probe for metal ion speciation studies

Synergistic Reinforcement of Composite Hydrogels with Nanofiber Mixtures of Cellulose Nanocrystals and Chitin Nanofibers

“…The solids content of PVA can be controlled through initial solution processing followed by subsequent drying and/or water absorption. The resulting hydrogels are solid, highly elastic, and relatively insoluble in water. , These properties, combined with their low protein absorption and biocompatibility, have motivated investigations concerning the use of PVA-based hydrogels in a variety of biomedical applications including artificial cartilage, contact lenses, and wound dressings …”

“…The resulting hydrogels are solid, highly elastic, and relatively insoluble in water. 22,23 These properties, combined with their low protein absorption and biocompatibility, 27 have motivated investigations concerning the use of PVA-based hydrogels in a variety of biomedical applications including artificial cartilage, 28 contact lenses, 29 and wound dressings. 30 For applications, nanoparticles have been added to FT hydrogels to modulate their properties further.…”

On the design of Ag–morin nanocomposite to modify calcium alginate gel: framing out a novel sodium ion trap

“…The value of percent strain where the curves of storage and loss moduli intersect represents the strength of the viscoelastic material. 35,36 For the calcium alginate gel, this value is at 6, for the morin incorporated gel it is $2 and the nanocomposite incorporated gel, this value rises above 20 indicating the highest mechanical strength for this particular gel. A slight decrease in this value (from 6 to 2) in morin incorporated calcium alginate gel is evidently because of lesser involvement of Ca in gel formation due to interference by morin which results in lesser crosslinking and lesser mechanical strength of the gel.…”

“…This corrugated surface becomes modied with irregular granulations upon incorporation of morin ( Fig. 35,36 For the calcium alginate gel, this value is at 6, for the morin incorporated gel it is $2 and the nanocomposite incorporated gel, this value rises above 20 indicating the highest mechanical strength for this particular gel. The granulations become intense and more organized as Ag-morin nanocomposite is incorporated ( Fig.…”

Phase separation in aqueous systems for realizing virtually significant extractions

“…So, all the probable combinations for ABSs resulting out of the above phase forming solutions were sorted. These result in the formation of some completely new aqueous two-phase systems as well as some interesting outcomes like gel formation of PVA solution in presence of Na-tartrate, 37 PEG and co-polymer PPG-PEG-PPG solutions were observed. The systems are represented pictorially in Fig.…”
