Lignin plasticization to improve binderless fiberboard mechanical properties
2005
Authors : Jalloul J. Bouajila and Catherine C. Joly
Hide abstract
Mechanical properties of binderless fiberboard are correlated to the hydrothermal history of the fibers during the board process. Water and temperature thickness gradients allow to calculate a gradient of T-Tg difference (7g, local glass transition temperature, function of localwater content; T, local temperature). This gradient explains the variation of mechanical properties within the thickness and in time. The in situ plasticization of lignin, which is supposed to increase the T-Tg difference, improves the macroscopic mechanical properties of fiberboards.

Characterization of small peptides in Champagne wine by liquid chromatography/tandem mass spectrometry
2004
Authors : Marine M. De Person, Francis F. Duchiron and Laurent L. Perrot
Hide abstract
This paper reports the use of an on-line LC–ESI–MS/MS method for the identification and quantification of di- and tripeptides in champagne wine without laborious sample pretreatment. The identification of these compounds, in their underivatised form, is based on identical retention times and ESI–MS spectra to those of reference standards. The presence of nine dipeptides (Arg–Ile, Ile–Arg, Ile–Val, Lys–Phe, Lys–Tyr, Phe–Lys, Tyr–Gln, Tyr–Lys, Val–Ile) and the absence of two tripeptides (Phe–Arg–Arg and Lys–Met–Asn) have been evidenced in the matrix. Calibration curves for each analyte were established using Phe–Arg as internal standard. The calibration curves were linear in the concentration range 0.1–10 mg L(-1) with a determination coefficient, r(2), better than 0.992. The accuracy for the calibration standard was estimated at between 92 and 102%. This method allows high recovery and satisfies the necessary requirements with respect to accuracy, repeatability and sensitivity. The first application of this analytical method to the measurement of di- and tri-peptides in different vintages of champagne wine is reported. Compositional changes in the peptides occurred depending on the vintage.

Gas transport properties of starch based films
2004
Authors : Isabelle I. Alric, Patrice P. Dole, E.E. Espuche and Nathalie N. Gontard
Hide abstract
This paper deals with gas transport properties of starch based films. Oxygen permeability of plasticised starch, octanoated starch, starch-EVOH blend, and PE-starch multilayer was first studied. The best gas barrier properties of starch based films are generally obtained for low water and plasticiser contents. It was then shown that the interesting low permeability of these systems is due to the low solubility of gases. These results broaden the scope of starch gas transport properties, which are generally discussed in terms of mobility (i.e. gas diffusivity)
