Synthesis and Characterization of Konjac Glucomannan-Graft-Polyacrylamide via γ-Irradiation

Molecules, 2008
The synthesis of konjac glucomannan-graft-polyacrylamide (KGM-g-PAM) wascarried out at 25°C by γ-irradiation under a N2 atmosphere. The effects of absorbedradiation dosage and monomer concentration on grafting yield and water absorbency werestudied.

Tissue Reaction to Low-Density Polyacrylamide Gel as a Carrier for Microimplants in the Adipose Fin of Rainbow Trout

Gels, 2023
The implantation of optical sensors is a promising method for monitoring physiological parameters of organisms in vivo. For this, suitable hydrogels are required that can provide a biocompatible interface with the organism’s tissues.

Synthesis and Performance Evaluation of a Novel High-Temperature-Resistant Thickener

Molecules, 2023
Successful exploitation of carbonate reservoirs relies on the acid-fracturing process, while the thickeners used in this process play a key role. It is a common engineering problem that thickeners usually fail to function when used in high-temperature ...

Flow Patterns of Polymer Solutions Injected into Dispersions of Bentonite

Applied Rheology, 2003
The flow behaviour of colloidal dispersions is largely influenced by the interactions between the dispersed particles. We studied the influence of either natural or synthetic polyelectrolytes solutions on flow patterns within colloidal clay dispersion ...
