Nature ’ s Nanocomposites : A New Look at Molecular Architecture in Wood Cell Walls

  title={Nature ’ s Nanocomposites : A New Look at Molecular Architecture in Wood Cell Walls},
  author={Stefan J Hill and Robert A. Franich and Paul T. Callaghan and Roger H. Newman},
A widely-accepted model for the molecular architecture of wood fails to account for the stick-slip deformation process, in which wet wood shows permanent plastic deformation without signifi cant mechanical damage. A proposed model interposes a layer of water molecules between cellulose microfi brils and the surrounding matrix. Results from proton spin diffusion, monitored via C NMR signal strengths, supported the new model. Pinus radiata D.Don latewood was soaked in D 2 O and a timescale of 10… CONTINUE READING
