Peroxidase-like nanozymes are nanoscale materials that can closely mimic the activity of natural peroxidase for a range oxidation reactions. Surface coating with polymer nanogels has been considered to prevent aggregation nanozymes. For long time, understanding largely limited its stabilization effect on nanozyme in aqueous media, while little is known about how plays role interaction substrate...

Three distinct polymers were used as model in this study: poly (vinyl alcohol) (PVA), polyacrylamide (PAM), and (ethylene glycol) (PEG). These employed to make nanocomposites films utilizing solution dry casting techniques with varied loading ratios of Silver nanopowders (AgNPs) (0.1, 0.2, 0.4 wt. percent). The varying thicknesses (950 nm). diffusion NPs among the gaps polymer mix particles was...

A series of gels were used as model foods to understand relationships among rheological properties and sensory texture. Fracture stress was the best predictor of sensory fracture force and particle breakdown, whereas a measure of the nonlinear region was a better predictor of sensory deformation. INTRODUCTION Food texture is a complex property involving a constant evaluation of the rheological ...

The purpose of the study was synthesis and physicochemical characterization spherical beads magnetically active composite ferrogels (FGs) with diameters 2–3 mm for further application to needs targeted drug delivery and/or replacement therapy. Spherical FGs based on a physical network calcium alginate (CaAlg), chemical polyacrylamide (PAAm), combined (PAAm/CaAlg) were analyzed. filled γ-Fe2O3 m...

Abstract The series of double network (DN) hydrogels, based on poly( N,N ′-diethylacrylamide) (PDEAAm), polyacrylamide (PAAm), or poly(2-acrylamido-2-methyl-1-propanesulfonic acid) (PAMPS) were synthesized with various mass ratios components and their thermal response was investigated. formation DN structure in studied hydrogels results significant increase Young’s modulus. PDEAAm/PAMPS exhibit...

In this study, magnesium hydroxide (Mg(OH)2) suspensions were flocculated using two polyacrylamide-poly(acrylic acid) copolymers with charge densities of 30% or 40%. Structural characteristics, including particle size distribution, shape and fractal dimension the resultant flocs investigated complementary techniques; static light scattering, focused beam reflectance measurement, automated optic...
