Through billions of years of evolution and natural selection, biological systems have
developed strategies to achieve advantageous unification between structure and bulk …

Nacre (known as mother of pearl) is the iridescent inner shell layer of some mollusks. Nacre
is composed of 95 wt% aragonite (a crystallographic form of CaCO3) and 5 wt% organic …

Seashells are abundantly available as waste products from the seafood industry and from
coastal areas. Accordingly, processed shells can be used to partially replace aggregates in …

The microstructures of the Saxidomus purpuratus shell were observed. It was found that the
inner and middle layers of the shell are composed of crossed lamellae, while the outer layer …

Laminated structure reduces the common inverse relationship of strength and toughness in
many biological materials. Here the mechanical behavior of pearl and nacre with spherical …

Rock-boring behavior is a common phenomenon among certain bivalve clams, yet the
mechanisms enabling this capability remain elusive. This study delves into the …

In this study, a newly developed nanoscale modulus mapping is applied in order to visualize
the 2D‐distribution of mechanical characteristics in the aragonitic nacre layer of Perna …

The bricks and mortar in the classic structure of nacre have characteristic geometry, aspect
ratios and relative proportions; these key parameters can be retained while scaling down the …

In this study, microhardness and flow strength (tensile) of a shell of an African Giant snail
(Achatina Fulica) were studied as a function of indentation load. The influence of loading …

The laminated composites reinforced with the strong and weak layers were fabricated by
lamination-bonding process in compliance with bionic multilayer structures. The strong …
