The microbial cycling of dimethylsulfoniopropionate (DMSP) and its gaseous catabolites dimethylsulfide (DMS) and methanethiol (MeSH) are important processes in the global sulfur cycle, marine microbial food webs, signaling pathways, atmospheric chemistry, and potentially climate regulation. Many functional genes have been identified and used to study the genetic potential of microbes to
Full-integral body technology and Baogang steel of light weight and high strength are applied, together with cathodic electrophoresis. So Efly can meet the latest national safety standard. To make the vehicle run more smoothly and elegantly and high-speed steering more stable, we install Macpherson front independent suspension and torsion beam rear suspension.

Polyacrylamide (PAM) is a polymer which is produced from acrylamide subunits through polymerization. Polyacrylamide (PAM) is majorly used to flocculate solids in a liquid due to its gel-like properties. There are mainly two types of Polyacrylami
- Why is anionic polyacrylamide chosen?
- Anionic polyacrylamide is chosen because the intramolecular electrostatic repulsion between polymer segments forces the polymer chains to adopt a more extended conformation, increasing the efficiency of bridging flocculation.
- What are the different types of anionic polyacrylamide synthesis technologies?
- The paper lists six different kinds of anionic polyacrylamide synthesis technologies, including homopolymerization posthydrolysis process, homopolymerization cohydrolysis process, copolymerization approach, inverse emulsion polymerization, precipitation polymerization and radiation polymerization.
- Can anionic polyacrylamide be used in water treatment?
- What's more, the authors discussed the application status of anionic polyacrylamide in water treatment. Based on these reviews, future research perspectives relating to its synthesis and application were proposed. This review summarizes the synthesis methods for anionic polyacrylamide.
- What is anionic polyacrylamide (Apam)?
- 1. Introduction Anionic polyacrylamide (APAM) is a kind of organic high-molecular polymer with high hydrophilicity and viscosity, which is easily dissolved in water [ , , ].
