Antifreeze (glyco) proteins are produced by many cold-acclimatized species to enable them to survive subzero temperatures. These proteins have multiple macroscopic effects on ice crystal growth which makes them appealing for low-temperature applications-from cellular cryopreservation to food storage. Poly(vinyl alcohol) has remarkable ice recrystallization inhibition activity, but its mode of a...
In the present study, poly(ethylene-co-vinyl alcohol) with 44 mol % ethylene content (EVOH44) was managed to be processed, for first time, by electrospinning assisted coaxial technology of solvent jacket. addition this, different suspensions cellulose nanocrystals (CNCs), contents ranging from 0.1 1.0 wt %, were also electrospun obtain hybrid bio-/non-bio nanocomposites. The resultant fiber mat...
Objective(s): Three-dimensional structures such as nanofibrous scaffolds are being used in biomedical engineering as well as provide a site for cells to attach and proliferate leading to tissue formation. In the present study, poly(vinyl pyrrolidone) (PVP)/ poly(vinyl alcohol)(PVA) hybrid nanofibrous scaffold was synthesized by electrospinning. Materials and Methods: The effect of adding nano h...
