Chemical enhanced oil recovery and the role of chemical

PAM was the first to be utilized as a displacing agent for chemical EOR, so it has been used as a reference system for subsequent modifications or improvements. The comparison can be either to check the increase in the oil recovery efficiency or to test their resistance to agents acting on detriment of their properties [73] .

Degradable Poly(ethylene glycol) Hydrogels for 2D and 3D Cell

PEG. Poly(ethylene glycol) is a hydrophilic polymer that, when cross-linked into networks, can have a high water content. PEG is a suitable material for biological applications because it does not generally elicit an immune response. 6 Since the 1970s, PEG has been used to modify therapeutic proteins and peptides to increase their solubility, lower their toxicity and to prolong their

polyacrylamide in agriculture and environmental land

Polyacrylamide in Agriculture and Environmental Land

Anionic polyacrylamide (PAM) has been sold since 1995 to reduce irrigation‐induced erosion and enhance infiltration. Its soil stabilizing and flocculating properties improve runoff water quality by reducing sediments, N, dissolved reactive phosphorus (DRP) and total P, chemical oxygen demand (COD), pesticides, weed seeds, and microorganisms in runoff.

The researchers turned to the anionic polymer Polyacrylamide (PAM), widely used in agriculture to prevent soil erosion. They tested the polymer on samples of burnt soils both in the lab, using a rainfall simulator, and out in the field under natural rainfall, using run-off plots in an area of Birya Forest that had been exposed to a moderate

This chemical structure enables to BChl b to absorb longer wave length light (~1100 nm) than BChl a. To investigate genes involved in the BChl b biosynthesis, we have constructed genomic DNA libraries from B. viridis and introduced them to mutants of the nonsulfur purple bacterium Rhodobacter capsulatus which is deficient in BChl a biosynthesis.
