Attachment of APAM to mineral particles in seawater
Science of The Total Environment, 2021 Polymer injection is used in enhanced oil recovery (EOR) when an oil field ages and the pressure in the reservoir decreases, or for oil fields with heavy oil. By polymer injection, the viscosity of the water injected for pressure support is increased by mixing with a high concentration of a polymer solution.

Analysis iron distribution methods in fine sand- and silt-sized soil particles
MethodsX, 2021 Iron is prone to change its form and speciation in phases. Thus, several methods have been developed to estimate iron partitioning in the mineral phases of soils. However, the accuracy of these methods to evaluate the iron contribution from minor phases,
