Research Projects (relevant to Action)

Measurements of the viscoelastic properties of the wood fiber cell wall, or of its constituents, in different hygro-thermal conditions using a specific Atomic Force Microscopy technique based on contact resonance analysis, coupled with microscopic characterizations of the cell wall (macro)structure (e.g., MFA measurements). Comparisons with other AFM “mechanical” modes and acoustic measurements.
