چکیده
Ion beams from cyclotrons as a source of radiation with extremely high linear energy transfer (LET) are considered. Basic processes of energy dissipation in heavy ion tracks are reviewed and the main parameters characterizing the effects of accelerated heavy ions on matter are given in relation to the effects of low-LET radiation. Modification of polymers by using cyclotron beams is discussed with the emphasis on some most recent results. Track membrane production is presented in more detail as an example of industrial application of cyclotron beams.

Palladium nanoparticles synthesis using polymeric matrix: poly(ethyleneglycol) molecular weight and palladium concentration effects
Due to unique applications of palladium nanoparticles, synthesis of these nanoparticles by a simple and low cost method is very important. In this work, Pd nanoparticles were synthesized with narrow size distribution by loading metal salt (Pd(OAc)2 ) into the polymeric matrix (PEG) as reducing agent and stabilizer. Also, the effect of metal salt concentration and PEG molecular weight on the con...
