Radiation-Induced Polymerization by Free Ions

Immobilization of yeast cells by radiation-induced polymerization.

Radiation-induced polymerization method was applied to the immobolization of yeast cells. The effects of irradiation, cooling and monomer, which are necessary for polymerization, were recovered completely bu subsequent aerobic incubation of yeast cells. The ethanol productive in immobilized yeast cells increased with the increase of aerobic incubation period. The growth of yeast cells in immobi...

Acceleration of fibrin polymerization by calcium ions.

T HE FINAL STEPS OF THE CLOTTING PROCESS, in which fibrinogen (Factor I) is transformed to fibrin through the action of thrombin, is customanily described as taking place in three stages. Initially, thrombin, a proteolytic enzyme of high substrate specificity, cleaves four arginyl-glycine bonds in each fibrinogen molecule, so that two pairs of peptide fragments are released. During the second s...

Photo and Radiation Induced Ionic Polymerization

Photo-induced cationic polymerizations of styrene and x-methylstyrene, which are weak electron donors and contain no hetero atom, were carried out in the presence of electron acceptors such as tetracyanobenzene and pyromellitic dianhydride to elucidate the polymerization mechanism initiated through an excited charge transfer interaction. Cyclohexene oxide was also polymerized by photo-illuminat...

Free-electron-laser radiation induced by a periodic dielectric medium.

Recent Advances in Photo-Induced Free-Radical Polymerization

Free radical photopolymerization dominates most of the industrial applications of photocuring. The most popular are protective coatings, dental fillings, adhesives, inks, lithography (printing plates), stereolithography but also advanced hightechnology purposes (micro and optoelectronics, holographic data storage, etc.) [1]. Currently, radical photopolymerization is also applied to prepare new ...
