Starch Modified Tough Biocompatible Polyurethane/acrylamide bio Composites: Physicochemical Properties and Biodegradation Studies

Physicochemical Properties of Rice Starch Modified by Hydrothermal Treatments

Cereal Chem. 84(5):527-531 Rice starches of long grain and waxy cultivars were annealed (ANN) in viscosity peak heights, lower setbacks, and greater swelling consistency. excess water at 50°C for 4 hr. They were also modified under heat-moisThe modified starch showed increased gelatinization temperatures and tore treatment (HMT) conditions at 110°C with various moisture contents narrower gelati...

Characterizing Physicochemical Properties of Enset Starch

Composites prepared from the waterborne polyurethane cationomers—modified graphene. Part I. Synthesis, structure, and physicochemical properties

In the reaction of 4,4'-methylenebis(phenyl isocyanate), polycaprolactone diol, and N-methyldiethanolamine, they were synthesized aqueous dispersions of polyurethane cationomers, from which films were prepared after adding 0-2 wt% graphene. In order to obtain nanocomposites, graphene was previously noncovalent functionalized in tetrahydrofurane in the field of ultrasound. The chemical structure...

Physicochemical and metabolic properties of modified metallothioneins.

Attempts to crosslink metallothionein through lysine residues have resulted in trapping of octameric structures. Two such polymers have been characterized. They are of a critical size for glomerular filtration, and unique tissue distributions of cadmium arise when they are injected into rats.

Biocompatible functionalisation of starch.

The enzyme catalysed esterification of starch and fatty acids with terminal triple bonds is described. This material can be used as an acceptor for azide containing molecules, through azide/alkyne cycloaddition. The potential is illustrated by the production of fluorescently-labelled starch, and a biotinylated derivative which can bind streptavidin.
