Actin filaments are major determinants of cell shape, motility and adhesion, which control important biological processes including embryonic development and wound healing. These processes are associated with changes in actin assembly, which is regulated by controlling the balance between polymerized and non-polymerized actin. To maintain a significant pool of non-polymerized actin, mechanism(s...

The poly(styrene-methyl methacrylate) latex particles as potential physical shale stabilizer were successfully synthesized with potassium persulfate as an initiator in isopropanol-water medium. The synthesized latex particles were characterized by Fourier transform infrared spectroscopy (FT-IR), particle size distribution measurement (PSD), transmission electron microscopy (TEM), and thermal gr...

cellulose was modified by polystyrene (ps) and polyacrylonitrile (pan) via free radical and living radical polymerization, and then cellulose was used as the matrix in the preparation of polymer/clay nanocomposite, through a solution intercalation method. for this purpose, first, the graft polymerization of styrene (st) onto cellulose fibers was performed by using suspension polymerization and ...

Acrylic bone cements have been used for about 40 years to fix artificial prosthesis to bone structure. The properties of the acrylic bone cement mostly depend on the characteristics of the beads, which are the main component of the solid part of the cement. In this work beads of poly(methyl methacrylate-co-styrene) were synthesized by suspension polymerization. The objective of this study was t...

Cationic polyacrylamide (CPAM) was synthesized by aqueous two-phase polymerization technique using acrylamide (AM) and dimethylaminoethyl methacrylate methyl chloride (DMC) as raw materials, aqueous polyethylene glycol 20000 (PEG 20000) solution as dispersant, 2,2′-azobis(2-amidinopropane) dihydrochloride (V-50) as initiator and poly(dimethylaminoethyl methacrylate methyl chloride) (PDMC) as st...
