a simple method of drying polyacrylamide slab gels that eliminates cracking
1.5-mm thick 7.5% polyacrylamide gel can dry in about 24 h, whereas gels of the same thickness with a 4–20% polyacrylamide gradient may take up to 36 h to dry completely. gels with a thickness of only 1 mm dry faster. this method therefore takes [3,4

drying polyacrylamide gels
introduction this protocol describes a method for drying polyacrylamide gels. gels containing proteins radiolabeled with 35 s-labeled amino acids must be dried before autoradiographic images can be obtained.nonradioactive gels can also be
polyacrylamide degradation and its impact on environmental systems.high molecular weight high quality polyacrylamide (pam) is commonly used as a flocculant in water and wastewater treatment, as a soil conditioner, and as a viscosity
polyacrylamide degradation and its implications in environmental systems npj clean water nature
the term “polyacrylamide” is loosely used to describe any polymer with acrylamide present as one of the monomers. 1 more rigorously, its iupac nomenclature is poly (prop-2-enamide), which
flocculation characteristics of polyacrylamide grafted cellulose from phyllostachys heterocycla: an efficient and eco-friendly flocculant,an efficient eco-friendly cellulose-based flocculant, bpc-gpam was designed and successfully prepared by free-radical graft copolymerization in homogeneous aqueous solution. flocculation of the synthesized bpc-gpam was evaluated by jar test procedure using the standard kaolin suspension and effluent from paper mill, comparing with the treatment of commercial pam.
optimization of partially hydrolyzed polyacrylamide (hpam) utilized in water-based mud while drilling
water-soluble polymers are becoming increasingly important in various applications, such as stabilizer fluids and drilling muds. these materials are used as viscosifiers and filtration control agents, flocculants, and deflocculants due to their superior properties in increasing viscosity and gelling ability in the presence of crosslinkers. in general, studying the rheological behavior of
