Presenting an optimal hydrogel for water shutoff, based on the bulk and rheological properties, was the main purpose of this research. To determine gelation time, a bottle test was
Helpful hints for analyzing in vitro transcription/translation reactions on polyacrylamide gels
In this article, we examined the effects of nonoptimal SDS polyacrylamide gel electrophoresis(SDS-PAGE) loading and running conditions on the results of cell-free protein expression reactions using the TNT T7 Quick for PCR DNA System. Nonoptimal
The alkaline reacts with natural acids in the oil, leading to the generation of in-situ soaps at the oil-water interface []. The in-situ soaps result in IFT reduction and reduce the adsorption of surfactant on rock surface. This reaction strongl
Radiation synthesis of porous calcium silicate aerogel derived from polyacrylamide hydrogel as thermal insulator
In this article, the first aerogels synthesis through cross-linked polyacrylamide (PAAm) hydrogel was reported through the use of gamma irradiation technique. Hydrogel obtained from gamma irradiation of acrylamide monomer dissolved in a solution
In the face of complex water quality changes, the application of existing cationic polyacrylamide has been largely limited. In this study, a series of cationic polyacrylamides
- What is polyacrylamide (PAM)?
- Polyacrylamide (PAM) is a long chain, linear, water soluble polymeric substance formed from acrylamide (C 3 H 5 NO) subunits, has a high molecular weight of typically from few 1000 to 20 × 10 6 g/mol, and has a very high viscosity in aqueous solutions, depending on the concentration and the degree of polymerization (Sojka et al. 2007).
- Why is polyacrylamide not a polyamide?
- It can be viewed as polyethylene with amide substituents on alternating carbons. Unlike various nylons, polyacrylamide is not a polyamide because the amide groups are not in the polymer backbone. Owing to the presence of the amide (CONH 2) groups, alternating carbon atoms in the backbone are stereogenic (colloquially: chiral).
- Are cationic polyacrylamide copolymers bad for the environment?
- Cationic polyacrylamide copolymers (PAMs) are used for sludge dewatering in municipal waste water treatment and might enter the environment by spreading of the sludge on agricultural land. Concern has been expressed since little is known about the degradation of PAMs in soils.
- How is polyacrylamide gel prepared?
- Polyacrylamide gels are prepared by free radical polymerization of acrylamide and a comonomer crosslinker such as bis-acrylamide. Polymerization is initiated by ammonium persulfate (APS) with tetramethylethylenediamine (TEMED) as the catalyst (see figure below).
