Optical Properties and van der Waals - London Dispersion Interactions of Polystyrene Determined by Vacuum Ultraviolet Spectroscopy and Spectroscopic Ellipsometry

The interband optical properties of polystyrene in the vacuum ultraviolet (VUV) region have been investigated using combined spectroscopic ellipsometry and VUV spectroscopy. Over the range 1.5-32 eV, the optical properties exhibit electronic transitions we assign to three groupings, E 1 , E 2 , and E 3 , corresponding to a hierarchy of interband transitions of aromatic (π → π*), non-bonding (n → π*, n → σ*), and saturated (σ → σ*) orbitals. In polystyrene there are strong features in the interband transitions arising from the side-chain π bonding of the aromatic ring consisting of a shoulder at 5.8 eV (E 1 ) and a peak at 6.3 eV (E 1 ), and from the σ bonding of the C-C backbone at 12 eV (E 3 ) and 17.1 eV (E 3 ). These E 3 transitions have characteristic critical point line shapes associated with one-dimensionally delocalized electron states in the polymer backbone. A small shoulder at 9.9 eV (E 2 ) is associated with excitations possibly from residual monomer or impurities. Knowledge of the valence electronic excitations of a material provides the necessary optical properties to calculate the van der Waals-London dispersion interactions using Lifshitz quantum electrodynamics theory and full spectral optical properties. Hamaker constants and the van der Waals-London dispersion component of the surface free energy for polystyrene were determined. These Lifshitz results were compared to the total surface free energy of polystyrene, polarity, and dispersive component of the surface free energy as determined from contact angle measurements with two liquids, and with literature values. The Lifshitz approach, using full spectral Hamaker constants, is a more direct determination of the van der Waals-London dispersion component of the surface free energy of polystyrene than other methods.

In this study coaggregation interactions between Rhodococcus and Acinetobacter strains isolated from food processing surfaces were characterized. Rhodococcus sp. MF3727 formed intra-generic coaggregates with Rhodococcus sp. MF3803 and inter-generic coaggregates with two strains of Acinetobacter calcoaceticus (MF3293, MF3627). Stronger coaggregation between Acinetobacter calcoaceticus MF3727and Rhodococcus sp. MF3293 was observed following growth in batch-culture at 30 °C as opposed to 20 °C, after growth in Tryptic Soy broth as compared to liquid R2A medium, and between cells in exponential and early stationary phase as compared to late stationary phase. The coaggregation ability of Rhodococcus sp. MF3727 was maintained even after heat and Proteinase K treatment, suggesting the ability to coaggregate was protein independent while the coaggregation determinants of the other strains involved proteinaceous cell-surface-associated polymers.Coaggregation was stable at pH 5-9. The mechanisms of coaggregation among Acinetobacter and Rhodococcus strains bare similarity to that displayed by coaggregating bacteria of oral and freshwater origin, with respect to binding between proteinaceous and nonproteinaceous determinants and the effect of environmental factors on coaggregation.Coaggregation may contribute to biofilm formation on industrial food surfaces, which can protect bacteria against cleaning and disinfection.
