Isolation and Characterization of Polyacrylamide-Degrading
Polyacrylamide (PAM) is a water-soluble polymer that is widely used as a flocculant in sewage treatment. The accumulation of PAM affects the formation of dewatered sludge and potentially produces hazardous monomers. In the present study, the bacterial strain HI47 was isolated from dewatered sludge.

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

Synthesis of million molecular weight polyacrylamide with
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

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.
