Two multistep extractions were achieved on porcine aortic tissues to obtain acellular matrices used for cardiac bioprostheses. The evaluation of structural modifications and the possible damage of extracellular matrix fibrous proteins were investigated by means of thermogravimetric analysis (TGA) and differential scanning calorimetry (DSC). Protein-water(More)
The purpose of this work was to characterize the viscoelastic behaviour of oral mucosa and compare it with the dynamic mechanical properties of different soft liners. For this purpose, a sample of pig oral mucosa and six commercialized soft liner samples have been investigated. A comparison was also carried with the first suitable hard rubber for dental(More)
This paper reports on the fabrication of a new capacitive humidity sensor having good characteristics and being robust enough to be considered as a component in industrial processes. This sensor is manufactured using a mixture of three cellulose acetate butyrates cross-linked by a melamine formaldehyde resin as sensing material. Details of the fabrication(More)
OATAO is an open access repository that collects the work of Toulouse researchers and makes it freely available over the web where possible.

Thanks to mutant CAD C/D, &#x03B2;<inf>Lignine</inf> mode has been associated with the molecular mobility of lignin polar groups (-OH). In this mutant, the genetic modification changes the chemical structure of lignin and increases the proportion of hydroxyl groups. The increase of hydroxyl groups ratio promotes hydrogen bonds which inhibits molecular(More)
The dielectric properties of elastin were investigated at different levels of hydration and specifically at the limit of freezable water apparition. The quantification of freezable water was performed by Differential Scanning Calorimetry (DSC). Two dielectric techniques were used to explore the dipolar relaxations of hydrated elastin: dynamic dielectric(More)
Differential scanning calorimetry (d.s.c.) and thermally stimulated current (t.s.c.) have been applied to the study of thermal transitions and dielectric relaxations of a pentapeptide sequence: Gly-Leu-Gly-Gly-Val of elastin. The manifestation of the glass transition has been observed by both techniques. The analysis of the fine structure of t.s.c. spectra(More)
Purified and hydrated elastin is studied by both thermal and dielectric techniques to have insight into the chain dynamics of this protein. By differential scanning calorimetry, the glassy behavior of elastin is highlighted; the glass transition temperature (T(g)) of elastin is found to be widely dependent on hydration, falling from 200 degrees C in the(More)
The molecular dynamic in hydrated cellulose has been investigated by a combination of thermal analyses and dielectric spectroscopy. Differential Scanning Calorimetry (DSC) shows the dependence upon hydration of the glass transition temperature Tg. A physical ageing phenomenon has been observed. At the molecular scale, bound water is hydrogen bonded to polar(More)
