Investigating Acoustic Properties of Biocomposite from Waste Streams
Biocomposites are a type of material. Recently, research and development into biocomposites have experienced a resurgence, as they are environmental friendly material. As part of the “green” industries, biocomposites decrease the demands on traditional, synthetic or petroleum carbon based products. …

Mapping of elastic modulus and hardness in Trochus niloticus seashell nacre by nanoindentation
… Trochus niloticus. Nacre is a hierarchical biocomposite composed of mineral tablets of 95 weight % calcium carbonate (CaCO3) in the aragonite mineral form and a biomacromolecular organic matrix. Nanoindentation was carried out in a pattern of square grids of 256 indents at maximum loads of 1 …

Multiscale mechanical studies of nacre from gastropod mollusk Trochus Nilocitus
… an individual platelet. This study shows that a biocomposite principally composed of a poor ceramic (aragonite) can achieve surprisingly good macroscopic mechanical properties thanks to a complex hierarchical structure allowing an extraordinary variety of energy-dissipating mechanisms. Our aim is …

Self-Assembly of Pullulan Abietate on Cellulose Surfaces
Wood is a complex biocomposite that exhibits a high work of fracture, making it an ideal model for multiphase man-made materials. Typically, man-made composites demonstrate interfacial fracture at failure due to abrupt transitions between neighboring phases. This phenomenon does not occur in wood …
