Abstract

The migration and delivery of filter flavour agents were studied by dissolving 10 model flavour compounds in triacetin at 10 mg/ml each and fabricating cigarettes with flavoured filter tips. The concentrations of these compounds in filters, tobacco, and smoke particulates collected on Cambridge filters were determined by capillary column gas chromatography initially and after 1, 2, 4, 6, and 8 weeks. Flavour migration was found to obey first-order kinetics, with the rate constant being determined by the volatility of the flavour compound dissolved in the plasticized filter. Delivery of flavour compounds decreased with time at a greater rate than could be explained by flavour migration. A high correlation between the solubility characteristics of the flavour and its rate of delivery efficiency loss lead to the proposed explanation that flavour compounds diffuse into the cellulose acetate fibers with time and become less accessible for elution into the smoke aerosol. Model compounds with poor solubilities in plasticized cellulose acetate remain near the surface of the fibers where they are readily eluted into the mainstream smoke and, consequently, exhibit smaller delivery efficiency losses with time. Ventilation was observed to initially increase the ratio of flavour to TPM delivery, but this advantage was lost as the cigarette aged.

Abstract

The projector augmented-wave method within the density functional theory is applied to investigate the oxygen diffusion in the intermetallic Ti-Al alloys. It is shown that the highest oxygen absorption energies in Ti-Al alloys correspond to the octahedral Ti-rich sites but the presence of aluminium in the nearest neighbours leads to a substantial decrease in the oxygen absorption energy in the alloys. The migration barriers for the oxygen diffusion between various interstices in the crystal lattice of the Ti-Al alloys are estimated. The preferred migration paths along a and c axes and limiting barriers of the oxygen diffusion in the alloys are determined. The dependence of the oxygen diffusion coefficient on Ti-Al alloy composition is discussed.

Review - Flavins as photoreceptors of blue light and their spectroscopic properties

This review describes 1) the development of studies on flavin photoreceptors as blue light photoreceptors in many living organisms: their kinds and functions; 2) the studies on spectroscopic properties of flavins, both their dimers and monomers; 3) nonradiative excitation energy transport in the presence of monomers and fluorescent/nonflurescent FMN dimers (excitation traps). The existence equilibrated luminescent FMN centers, energy migration and excitation sink to FMN dimers are taken into account.
