Young's moduli of selected amino acid molecular crystals were studied both experimentally and computationally using nanoindentation and dispersion-corrected density functional theory. The Young modulus is found to be strongly facet-dependent, with some facets exhibiting exceptionally high values (as large as 44 GPa). The magnitude of Young's modulus is strongly correlated with the relative orientation between the underlying hydrogen-bonding network and the measured facet. Furthermore, we show…

TLDR
A linear correlation is established between Young's modulus and the strength and orientation of the hydrogen bond network developed along the crystals, showing that stiffness in these materials is primarily dictated by hydrogen bonding.

Abstract Young's modulus of elasticity of organic drugs and excipients as determined by 3-point beam bending can be predicted from cohesive energy density. However, the moduli are lower than expected
Using the bending beam model to estimate the elasticity of diphenylalanine nanotubes.
TLDR
This study applied the bending beam model to atomic force microscopy images of diphenylalanine nanotubes suspended across cavities and obtained the Young's modulus 27 +/- 4 GPa and the shear modulus 0.21 +/- 0.03 GPa, which furthers the understanding of the structure and properties of these nanot tubes.

TLDR
It is revealed that despite the porous nature of the lattice, there is an array of rigid nanotube backbones with interpenetrating "zipper-like" aromatic interlocks that result in stiffness and robustness and may pave the way for rational design of bionanomaterials.

Through nanoindentation it is possible to correlate molecular-level properties such as crystal packing, interaction characteristics, and the inherent anisotropy with micro/macroscopic events such as desolvation, domain coexistence, layer migration, polymorphism, and solid-state reactivity.
