Mapping of elastic modulus and hardness in Trochus niloticus seashell nacre by nanoindentation
Positionally-sensitive nanoindentation was carried out in the freshly-cleaved nacre found in the shell of the gastropod mollusk Trochus niloticus. Nacre is a hierarchical biocomposite composed of mineral tablets of 95 weight % calcium carbonate (CaCO3) in the aragonite mineral form and a …

Mechanics of Seashell Growth: Examining the relationship between incompatibility, shape, and internal stress
Seashells are a fascinating example of surface growth in nature. As they develop, both their macroscopic form and their internal microstructure evolve, with the latter transitioning between different layer sizes and orientations during the shell's growth process. Several studies have examined the …

Mechanical behavior of ultrastructural biocomposites
… to investigate the microscale features of seashell nacre to reveal the nucleation points within tablets, the sector boundaries and an overlap between tablets of neighboring layers of [approx.] 20 %. Aragonite, the mineral constituting the inorganic phase of nacre, is a calcium carbonate …

A modern history of monetary and financial systems of Congo 1885-1995
… currency in the Kingdom of Congo - the nzimbu, a seashell as small as a coffee bean, and the lubongo, a small mat made of raffia fibre - are analysed. Mbongo, the common term for money or wealth in today's Congolese languages, derives from lubongo. The mitako, a brass rod of different lengths, …
