What is the percentage compressibility of a wood
Answers
Answer:
Mechanical compressibility and elasticity of the wood sponge. (a) Photographs of the wood sponge showing its reversible compressibility along the layer-stacking direction. (b) Stress−strain curves of the wood sponge under compression with different maximum strains of 20%, 40%, and 60%, respectively. (c) Stress−strain curves of wood sponge under cyclic compression at the maximum strain of 40%. (d) Height retention and energy loss coefficient of the wood sponge during different cycles derived from the stress−strain curves in (c).

... well-aligned cellulose nanofibers in the secondary cell wall (diameter, 20−30 nm) were distinctly exposed ( Figure S2). The formation of numerous nanoscale pores due to delignification was supported by the Brunauer−Emmett−Teller analysis through physisorption of N 2 ( Figure S3). The specific surface area (SSA) increased notably from 3.3 m 2 g −1 in the natural wood to 21.6 m 2 g −1 in the delignified wood. ...
