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.

Review of ASP EOR (alkaline surfactant polymer enhanced oil
PAM (Polyacrylamide) Polyacrylamide ( Fig. 6 a) was the first polymer used as a thickening agent for aqueous solutions. The thickening capability (increase of the corresponding solution viscosity) of PAM resides mainly in its high molecular weight, which reaches relatively high values (>1 × 10 6 g/mol).

The PAM1 treatments resulted in 0.5 mg L(-1) drain water polyacrylamide concentrations 1.6 km downstream of PAM addition, while PAM5 and PAM10 treatments produced > 2 mg L(-1) drain water polyacrylamide concentrations. We concluded that, although PAM practically eliminates Imperial Valley tailwater sediment loads, it does not effectively reduce

Functionalization of Graphene: Covalent and Non-Covalent
Graphene, the two-dimensional sp 2-hybridized carbon, is currently, without any doubt, the most intensively studied material.This single-atom-thick sheet of carbon atoms arrayed in a honeycomb pattern is the world’s thinnest, strongest, and stiffest material, as well as being an excellent conductor of both heat and electricity.

Materials for Energy Applications: Li-ion, Na-ion Batteries
Graphene (Gr), a transparent semi-metal has superior performances in transmittance, conductivity and mechanical strength [1,2]. Associated with hafnium oxide (HfO2) which present high k value (~ 22), high band gap energy (5.68 eV) and thermal stability, graphene allows the manufacture of MSCs with high capacitance and low power consumption [3,4].
