Journal ArticleDOI
C60 in Model Biological Systems. A Visible-UV Absorption Study of Solvent-Dependent Parameters and Solute Aggregation
TL;DR: In this paper, a study of the solubilization of C[sub 60] in various solvents and systems of biological interest, i.e., octanols, micelles, and liposomes, using visible-UV absorption spectroscopy as a diagnostic tool was made.
Journal ArticleDOI
Concentration and wavelength dependence of the effective third-order susceptibility and optical limiting of C60 in toluene solution
TL;DR: In this article, the authors showed that the nonlinear optical response due to instantaneous two-photon absorption can be used to yield effective values of the relevant parameters of optical nonlinearity due to reverse saturable absorption.
Journal ArticleDOI
Size effects on dissociation rates of polycyclic aromatic hydrocarbon cations : laboratory studies and astrophysical implications
Journal ArticleDOI
Photoion mass spectrometry of adenine, thymine and uracil in the 6–22 eV photon energy range
TL;DR: Using synchrotron radiation as excitation source in the 6-22 eV photon energy region, a photoionization mass spectrometry study of three nucleic acid bases, adenine, thymine and uracil, revealed VUV-induced degradation pathways of these important biological molecules as discussed by the authors.

TL;DR: In this article, a photoionization mass spectrometry study in the 6 −22 eV photon energy region of five amino acids, glycine-h5 and its -d5 isotopologue, a-alanine, b -alanine and a-aminoisobutyric acid and avaline, revealed VUV-induced degradation pathways of these important biological molecules.
