As alternative radiolytic approach, the synthesis of P3HT was made possible thanks to oxidation 3HT monomers by chloromethyl and dichloromethyl radicals or their corresponding peroxyl in situ produced dichloromethane solvent radiolysis. Under two different experimental conditions, oxygen-free solution oxygen-saturated solution, polymers, “P3HTN2” “P3HTO2” respectively, were successfully synthes...

Modern radiation techniques aim on improved 3-dimensional (3D) spatial selectivity of the dose application sparing dose from organs-at-risk (e.g. IMRT with micro-multileaf collimation, γ-knife-, Brachyand heavy-ion therapy). The corresponding 3D-dose distributions exhibit high dose gradients above 4 Gy/mm, which are difficult to be investigated using standard single-point dosimetric detectors ...

as we know oxygen is one of the main inhibitors of polymerization of vinyl acetate. therefore, nitrogen is used in order to make sure of system's high purity. to maintain purity it is necessary to find out the rate of the oxygensolution in polymerization system under different conditions of polymerization. it is concluded that incoming nitrogen to the system would remove the oxygen from th...

Actin polymerization has been shown to be sufficient to propel curved objects, for example beads and vesicles coated with the Listeria monocytogenes protein ActA. Recent studies suggest that actin polymerization on flat surfaces can also provide the propulsive force to push them forward.
