Synergistic Mechanism of Hydrolyzed Polyacrylamide
Branched-preformed particle gel (B-PPG) is a novel agent for EOR application in mature reservoirs. To improve the enhanced oil recovery (EOR) performance of B-PPG, the heterogeneous combination flooding system composed of B-PPG, hydrolyzed polyacrylamide (HPAM), and surfactant was proposed.
Abstract. SDS-PAGE is the most widely used method for qualitatively analyzing protein mixtures. It is particularly useful for monitoring protein purification, and because the method is based on the separation of proteins according to size, the method can also be used to determine the relative molecular mass of proteins (see Note 14).

Glyphosate is a non-selective common and effective herbicide. It is highly soluble in water, relatively volatile and does not normally leach to groundwater. It is not persistent in soils but may be in aquatic systems under certain conditions. It is moderately toxic to humans and a skin and eye irritant.
