Polyacrylamide in Agriculture and Environmental Land
The word polyacrylamide and the acronym “PAM” are generic chemistry terms, referring to a broad class of compounds.There are hundreds of specific PAM formulations. They vary in polymer chain length and number and kinds of functional group substitutions as well as molecular conformation, the most important conformation variation being linear or cross‐linked conforma

Acrylamide | C3H5NO - PubChem
Acrylamide is a colorless, odorless, crystalline amide that polymerizes rapidly and can form as a byproduct during the heating of starch-rich foods to high temperatures.. Acrylamide is used in the production of polymers mainly in the water treatment industry, pulp and paper industry and textile treatment industry and is used as a laboratory reage

Journal of Physics: Conference Series, Volume 3, 2004
Polyacrylamide gel (PAG) dosimetry provides a promising means for the calibration and verification of three-dimensional radiation dose delivery in modern conformal radiotherapy. PAG dosimetry is based on the radiation-induced copolymerization of acrylamide and bisacrylamide monomers in water and gelatin.

Review: nanoparticles and nanostructured materials
The introduction of nanoparticles (NPs) and nanostructured materials (NSMs) in papermaking originally emerged from the perspective of improving processing operations and reducing material consumption. However, a very broad range of nanomaterials (NMs) can be incorporated into the paper structure and allows creating paper products with novel properties. This review is of interdisciplinary

Increase in chlorophyll content for lettuce plants was observed only when it was applied with chitosan. In general, a radiation dose of 100 kGy showed the best results, with 77.7% of the plants having higher chlorophyll content than the control, and specifically 83, 66.6 and 54.1% for tomato, lettuce and cabbage plants, respectively.

Self-assembled silk sericin/poloxamer nanoparticles
Protein was quantified with a protein estimation kit using the Bradford Macro method (Bangalore Genei). Equal amounts (60 µg) of whole cell lysate were loaded and resolved in 10% sodium dodecyl sulfate–polyacrylamide electrophoretic gel (SDS-PAGE) and transferred to a polyvinylidene fluoride (PVDF) membrane electrophoretically.

Chemical modification of starch by reactive extrusion
Good mixing efficiency was one of more important experimental variables. The ratio of polystyrene homopolymer: to graft polystyrene obtained was ∼1:1. Synthesis of an MAH copolymer was argued to provide another mechanism for grafting through based-catalyzed ring-opening of the anhydride unit (see Section 3.3 ) and also provided higher monomer

Review: nanoparticles and nanostructured materials
Usually, the manufacture of products with advanced functionality is associated with complex processes and hazardous materials. A key to success is in understanding how the NMs, cellulose matrix, functional additives, and processes all interact to provide the intended paper functionality while reducing materials waste and keeping the processes

The major removal efficiency (35.59%) was achieved at a concentration of 0.44 g/L, but statistically, all concentrations, 0.44, 0.33, or 0.22 g/L, reduced stickies. At a concentration of 0.11 g/L of enzyme extract, there was also a reduction in contaminants, but it was not significantly different from the control.
