Water absorption in chitosan rapidly increases when the deacetylation degree decreases between 85
and 45%. This seems to contradict the fact that water absorption in chitin is much lower than that of
chitosan. The aim ...

A poly(ethyl acrylate) polymer network was swollen with different concentrations of the nonpolar solvent p-xylene, cpx, from xerogel until saturation (0 cpx 0.85). Differential scanning calorimetry (DSC) and thermally ...
Hydrogels based on nanocomposites of statistical poly(hydroxyethyl acrylate-co-ethyl acrylate) and silica, prepared by simultaneous copolymerization and generation of silica nanoparticles by sol-gel process at various ...
Water and polymer dynamics in hydrogels based on random copolymers of hydrophilic poly( hydroxyl ethyl acrylate) (PHEA) and hydrophobic poly(ethyl acrylate) (PEA), in wide ranges of composition, were investigated by means ...

[EN] Water and protein dynamics in two globular protein-water systems, water-lysozyme
and water-BSA (bovine serum albumine), were studied by differential scanning calorimetry (DSC), dielectric relaxation spectroscopy (DRS) ...
[EN] A new family of injectable hydrogels, enzymatically crosslinked from mixtures of tyramine conjugates of hyaluronic acid (HA) and gelatin (Gel) are characterized in terms of their molecular morphology, miscibility and ...
