      abstract     = {The elastic properties of crystals are fundamental for
                      structural material. However, in the absence of macroscopic
                      single crystals, the experimental determination of the
                      elastic tensor is challenging because the measurement
                      depends on the transmission of stress inside the material.
                      To avoid arbitrary hypotheses about stress transfer, we
                      combine hydrostatic pressure and uniaxial-stretching
                      experiments to investigate the elastic properties of
                      cellulose Iβ. Three orthogonal compressibilities are 50.0,
                      6.6, and 1.71 TPa–1. Combining Poisson’s ratios from a
                      uniaxial stretching experiment directly gives the Young’s
                      modulus along the chain direction ($E_{33}$). However,
                      Poisson’s ratio depends on the deformation rate leading to
                      apparent modulus $E_{33}$ = 113 GPa using a slow cycle
                      (hours) and 161 GPa using a fast cycle (minutes). The
                      lattice deformation along the chain is not time-dependent,
                      so the off-diagonal elements are time-dependent on the scale
                      of minutes to hours.},
