A porous nanotube network structure of metallic carbon

open access: yesResults in Physics, 2021
A porous nanotube network structure of carbon allotrope was designed, denoted as P4/mmm C96. Besides its structure similar to carbon nanotubes, the most interesting thing about P4/mmm C96 is that its band structure is metallic. The shear modulus G, Young’

The elastic modulus for maize stems [PDF]

open access: yesPlant Methods, 2018
Stalk lodging is a serious challenge in the production of maize and sorghum. A comprehensive understanding of lodging will likely require accurate characterizations of the mechanical properties of such plants. One of the most important mechanical properties for structural analysis of bending is the modulus of elasticity.
