  • flow patterns of bubble nucleation sites called fliers freely floating in champagne glasses
    Langmuir, 2007
    Co-Authors: Gerard Ligerbelair, Fabien Beaumont, Philippe Jeandet, Guillaume Polidori
    Abstract:

    Laser tomography techniques were used to capture the dynamics of bubbles released from particles (arbitrarily called fliers) freely floating in traditional flutes poured with champagne. By use of long exposure time photography, the trajectories of bubbles released by fliers were found to leave very elegant and characteristic “prints” as they crossed a section of champagne illuminated with a 1 mm thick laser sheet. This characteristic print was made with a succession of lighting filaments. Fine analysis of these prints left by fliers enabled us to deduce the bubbling frequency of each flier (which ranged from about 4 bubbles/s up to about 22 bubbles/s a few seconds after pouring), as well as its velocity through the liquid medium (which ranged from about 0.8 mm/s to about 7.6 mm/s). Finally, this flow visualization technique, very recently applied to the science of champagne and sparkling wines, also proved to be a useful technique to underscore fliers' bubbling instabilities along their rather erratic way...

  • Thermochromic ink - paper interactions and their role in biodegradation of UV curable prints
    Cellulose, 2018
    Co-Authors: Marina Vukoje, Snežana Miljanić, Jasna Hrenović, Mirela Rožic
    Abstract:

    In this study, biodegradability aspects of UV thermochromic leuco dye print on three different paper materials (synthetic, recycled, and bulky) were studied using the soil burial test under anaerobic conditions. Biodegradation of UV curable thermochromic prints were evaluated for changes by visual examination, microbial growth assay, weight loss measurements, Fourier transform infrared spectroscopy, scanning electron microscopy and colorimetric measurements. Results showed a better absorption of ink into the bulky paper structure, followed by recycled paper. Synthetic paper is not absorbent. The ink binder altogether with classic pigment and microcapsules penetrates into the structure of bulky paper. Recycled paper absorbs ink binder mostly with classic pigment. Better adsorption of binder into the bulky paper structure results in thinner layer of ink binder on the paper surface. On non-absorbent synthetic paper, microcapsules are covered with thicker layer of ink binder. In the case of bulky paper, the highest rate of biodegradation was observed, resulting in a higher number of bacteria, higher weight loss, higher changes in colour (destruction of almost all microcapsules) and almost complete reduction in thermochromic effect of the prints. Results show that microcapsules, which penetrate into the structure of bulky paper, are promoting the rate of bulky paper biodegradation. The opposite behaviour was noticed for the penetration of classic pigment into the structure of recycled paper, which resulted in remarkable reduction of recycled paper biodegradation rate. The thicker layer of ink binder (containing classic pigment) on the surface of microcapsules on recycled paper resulted in slower rate of microcapsules degradation and smaller colour change of the print. The thickest layer of ink binder and classic pigment on synthetic paper surface causes the slowest rate of biodegradation of print.

  • Thermochromic offset ink – paper interactions and print biodegradation
    Acta Graphica, 2018
    Co-Authors: Marina Vukoje, Mirela Rožic
    Abstract:

    This study examines the adhesion and interactions between thermochromic offset ink and different papers as well their role in papers and prints biodegradation.  Obtained results show that biodegradation of prints depends upon the adhesion, i.e. lower adhesion will result in reduction of biodegradation rate, while the strong adhesion will result in better paper degradation. Reactions between paper and thermochromic ink will form different prints properties due to different affinity of paper for ink while interactions between them will affect the prints biodegradation. When the ink is applied on paper, the polar interactions of paper will react with polar interactions of ink. Smaller amount of polar components of paper will give a print with polar character.
