Nanoscale Transforming Mineral Phases in Fresh Nacre.

Surprisingly, the abalone nacre data show the same ACC phases that are precursors to calcite (CaCO3) formation in sea urchin spicules, and not proto-aragonite or poorly crystalline aragonite (pAra), as expected for aragonitic nacre.

The Mesoscale Crystallinity of Nacreous Pearls

A pearl’s distinguished beauty and toughness is attributable to the periodic stacking of aragonite tablets known as nacre. Nacre is a naturally occurring mesocrystal that remarkably arises in the

Narrowly Distributed Crystal Orientation in Biomineral Vaterite

Biominerals formed by animals provide skeletal support and many other functions. They were previously shown to grow by aggregation of amorphous nanoparticles but never to grow ion-by-ion from

The mesoscale order of nacreous pearls

It is found that mollusks strike a balance between preserving translational symmetry and minimizing thickness variation of layers by creating a paracrystal with medium-range order by quantifying its structural coherence across entire pearl specimens.

Nanoscale assembly processes revealed in the nacroprismatic transition zone of Pinna nobilis mollusc shells

This investigation of the prism–nacre interface reveals nanoscale details governing the onset of nacre formation using high-resolution scanning transmission electron microscopy and gives new insights into nacre Formation and particle-accretion mechanisms that may be common to many calcareous biominerals.

Nacre tablet thickness records formation temperature in modern and fossil shells

Crystal lattice tilting in prismatic calcite.

Rotating lattice single crystal architecture on the surface of glass

A novel approach to fabricate RLS crystal lines and 2D layers of unlimited dimensions via a recently discovered solid-to-solid conversion process using a laser to heat a glass to its crystallization temperature but keeping it below the melting temperature is reported.

Small-misorientation toughness in biominerals evolved convergently

The hardest materials in living organisms are biologically grown crystalline minerals, or biominerals, which are also incredibly fracture-tough. Biomineral mesostructure includes size, shape, spatial



Crystallographic orientation inhomogeneity and crystal splitting in biogenic calcite

Orientational gradients and splitting processes are described in biocrystals for the first time and are undoubtedly related to the high content of intracrystalline organic molecules, although the way in which these act to induce the observed crystalline patterns is a matter of future research.

Multiscale structure of sheet nacre.

Synchrotron x-ray microbeam diffraction from abalone shell

Microstructured biomaterials such as mollusk shells receive much attention at present, due to the promise that advanced materials can be designed and synthesized with biomimetic techniques that take

Geometrical and crystallographic constraints determine the self-organization of shell microstructures in Unionidae (Bivalvia: Mollusca)

The microstructural arrangement of the unionid shell is, to a large extent, self–organized with the main constraints being crystallographic and geometrical laws.

Self-organisation of nacre in the shells of Pterioida (Bivalvia: Mollusca).

Mollusk shell nacre ultrastructure correlates with environmental temperature and pressure.

Strong correlation between nacre crystal misorientations and environmental temperature is found, further supported by secondary ion mass spectrometry measurements of in situ δ(18)O in the nacre of one shell.

Does Abalone Nacre Form by Heteroepitaxial Nucleation or by Growth through Mineral Bridges

We present experimental support for a model of abalone nacre growth that is based on mineral bridges between successive aragonite tablets rather than on heteroepitaxial nucleation. Interlamellar

Gradual ordering in red abalone nacre.

Synchrotron spectromicroscopy experiments revealing that stacks of aragonite tablet crystals in nacre are misoriented with respect to each other suggest that the self-ordering of the mineral phase, which may occur completely independently of biological or organic-molecule control, is fundamental in n acre formation.

Nanoscale waviness of low-angle grain boundaries

The lattice rotation across a LAGB in olivine measured at the nanometer scale by using quantitative high-resolution transmission electron microscopy reveals a grain boundary that is corrugated, providing the basis for a reexamination of grain-boundary properties in materials such as high-temperature superconductors, nanocrystalline materials, and naturally deformed minerals.

Structural and microstructural characterization of the growth lines and prismatic microarchitecture in red abalone shell and the microstructures of abalone flat pearls

The structure of the growth lines in the shell of the red abalone, Haliotis rufescens, has been characterized by X-ray diffraction analysis and by scanning and transmission electron microscopy. The
