Effect of the measurement contact scale on the thermomechanical characterization of biocomposite surfaces [PDF]

open access: yes, 2023
This paper proposes a multiscale surface characterization of biocomposites using the nanoindentation technique to identify the functional relationship between the measurement contact scale and the thermomechanical response of each biocomposite component,

Fungal biofilms as low-modulus structural biocomposites [PDF]

open access: yes, 2020
Biofilms are formed by microorganisms that collectively organise at interfaces. They are self-assembling complex fluids consisting of rigid microbial cells embedded in a self-secreted soft biopolymeric extracellular matrix and possess an intricate porous

Coordinated Architectural and Chemical Reinforcement in the Crushing Mandible of a Soldier Termite

open access: yesAdvanced Functional Materials, EarlyView.
The crushing mandible of a soldier termite withstands substantial biting loads despite lacking mineral. Its cuticle is partitioned: convex teeth pair hardness and zinc enrichment with aligned chitin fibers for contact durability, while stiffer concave regions between teeth carry bending loads.
