TL;DR: Positron annihilation lifetime spectroscopy is applied to the study of gamma irradiation effect on polymers based on the acrylate oligomers in this paper, where the measurements have been made on samples with different absorbed dose in the range 10-100kGy.
Abstract: Positron annihilation lifetime spectroscopy is applied to the study of gamma irradiation effect on polymers based on the acrylate oligomers. The measurements have been made on samples with different absorbed dose in the range 10–100 kGy. The longest lifetime, τ3, in three-component analyses of the spectra was associated with the pick-off annihilation of ortho-positronium trapped in free volumes. After irradiation changes in the o-Ps lifetimes and the relative intensity of the longest component, I3, was observed. These results are discussed on the basis of a free volume model.

TL;DR: An increase in rotational correlation time as the authors move from pure aqueous phase to solution containing surfactants of different head charge is observed as the experimentally obtained dipole moment data were justified and explained by the DFT calculations of the electronic properties of IN-O8-Cl molecules in gas phase and in selected solvents.
Abstract: The effect of solvent polarity and micellar headgroup on a newly designed imidazolium based ionic liquid (IL) conjugated with naphthalene, 1,2-dimethyl-3-((6-(octyloxy)naphthalen-2-yl)methyl)-1H-imidazol-3-ium chloride (IN-O8-Cl), was studied using steady state and time-resolved fluorescence techniques. We observed that the dipole moment in the excited state is remarkably higher than the ground state. The effect of micellar surface charge on the photophysics of IN-O8-Cl in aqueous phase at room temperature was investigated. Formation of premicellar aggregates in sodium dodecylsulfate (SDS) was perceived; further the microenvironment of IN-O8-Cl was examined using steady-state fluorescence spectroscopy. Micropolarity of the micellar environment of SDS was found to be lower than that of cetyltrimethylammonium bromide (CTAB) and triton X-100 (TX100) following the order SDS < TX-100 < CTAB. The binding constant (Kb) and edge excitation red shift (EERS) from the emission maximum suggest that the probe binds st...
