Investigations on synthesis and characterization
oxi de . Polyacrylamide (PAM) is an insulating polymer. It is easily soluble in water and non polar solvents , having good mechanical strength and air stability. In our study , we have found significant enhancement of electrical and mechanical properties of FGS -PAM composite s. The present studies on the preparation of FGS -PAM composites and

Isolation and Characterization of Polyacrylamide-Degrading
Polyacrylamide (PAM) is a water-sol uble polymer that is usually pr oduced through the polymerization autoclaving, and self-degradation in the experiment. Strains that showed good performance in their PAM removal efficiency were chosen for further study. Isolation and Characterization of Polyacrylamide-Degrading Bacteria from Dewatered
The maximum molecular weight of PAM reached 3600 kg/mol in an experiment with 8.0 mol/L AM as the monomers and 1 mmol/L K 2 S 2 O 8 as the initiator. These results successfully justify the microreactor as a good platform for preparing huge molecules.
Fabrication of porous polyacrylamide/polystyrene fibrous
The PAM/PS fiber was prepared via the electrospinning method (as shown in Fig. 1).Typically, 8.0 g PS pellets and 0.01 g PAM were added in the mixed solution of N,N-dimethyl formamide and chlorobenzene (95/5 vol./vol.).The PAM/PS fiber was obtained by the electrospinning method at an injection rate of 0.75 mL·h −1 with a distance of 19.0 cm between the needle and the receiver using a
The presence of TiO 2 nanoparticles caused a further reduction in MW to 3 × 10 4 Da. 81 Photocatalytic degradation is also enhanced in the presence of Fe 3+ at low pH. 83,84 The MW of PAM (15 mg

The fracture energy of the PDA–PAM hydrogel (2400 J m −2) is much higher than that of the pure PAM hydrogel (650 J m −2) and human cartilage (~1000 J m −2), 11 as measured by single-edge
Surfactant flooding is an enhanced oil recovery (EOR) technique that has a decent potential application in Malaysia’s oilfield. Du et al., [1] in their study has carried out evaluation on the most suitable enhanced oil recovery (EOR) technique to be applied in St. Joseph field, offshore Sabah, Malaysia.They identified that alkaline-surfactant-polymer (ASP) flooding is the best EOR technique
The Molecular Engineering of an Anti-Idiotypic Antibody
Anti-idiotype monoclonal antibodies represent a class of reagents that are potentially optimal for analyzing the pharmacokinetics of fully human, anti-infective antibodies that have been developed as therapeutic candidates. This is particularly important where direct pathogen binding assays are complicated by requirements for biosafety level III or IV for pathogen handling.
