Effects of relaxants before embedding nucleus for the survival rate and pearl qualities in Pinctada fucata [PDF]

Songklanakarin Journal of Science and Technology (SJST), 2006
Nucleation in the spherical pearl production from Akoya pearl oysters Pinctada fucata (Gould, 1850) obtained low survival rate, and the nuclei were frequently excluded.

Disordered dolomite as an unusual biomineralization product found in the center of a natural Cassis pearl.

PLoS ONE, 2023
Natural pearls are produced without human intervention, mainly due to various irritations from the surrounding environment to their mantle tissues.

Deep sequencing of ESTs from nacreous and prismatic layer producing tissues and a screen for novel shell formation-related genes in the pearl oyster. [PDF]

PLoS ONE, 2011
BACKGROUND: Despite its economic importance, we have a limited understanding of the molecular mechanisms underlying shell formation in pearl oysters, wherein the calcium carbonate crystals, nacre and prism, are formed in a highly controlled manner.

Characteristics of Coastal Low-Level Jets in the Boundary Layer of the Pearl River Estuary

Journal of Marine Science and Engineering, 2023
It is well-known that coastal low-level jets (CLLJs) play an essential role in transporting heat, water vapor and pollutants. However, the CLLJ characteristics in the Pearl River Estuary have not been deeply revealed due to the lack of long-term ...

Comparing the regeneration potential between PLLA/Aragonite and PLLA/Vaterite pearl composite scaffolds in rabbit radius segmental bone defects

Bioactive Materials, 2020
Mussel-derived nacre and pearl, which are natural composites composed CaCO3 platelets and interplatelet organic matrix, have recently gained interest due to their osteogenic potential.

Influence of Test Temperature and Test Frequency on Fatigue Life of Aluminum Alloy EN AW‐2618A

Advanced Engineering Materials, EarlyView.
The influence of test temperature and test frequency on the fatigue life of EN AW‐2618A is investigated. High‐cycle fatigue tests are performed at different test temperatures and frequencies on the 1000 h/230°C overaged state. Both test parameters reduce fatigue life due to time‐dependent damage mechanisms.

Correlation and Path Analysis Between the Quality of Nucleated Pearls from the Mantle of Hyriopsis cumingii and the Growth Traits of Host Mussels

Progress in Fishery Sciences
The triangle-sail mussel (Hyriopsis cumingii) is the most important freshwater pearl-bearing mussel in China. Nucleated pearls from the mantle of H. cumingii are emerging pearl cultivation products.

Donor and recipient contribution to phenotypic traits and the expression of biomineralisation genes in the pearl oyster model Pinctada margaritifera

Scientific Reports, 2017
Grafting associates two distinct genotypes, each of which maintains its own genetic identity throughout the life of the grafted organism. Grafting technology is well documented in the plant kingdom, but much less so in animals. The pearl oyster, Pinctada

Compatibility of Methacrylate Based Resins Controls Interfacial Failure and Toughness in 3D‐Printed Multimaterial Composites

Advanced Engineering Materials, EarlyView.
This work shows that the mechanical performance of multimaterial digital light processing (DLP) printed thermoset composites is governed by resin compatibility and interfacial design rather than spatial patterning alone. Brittle and ductile resin combinations produced premature interfacial failure, while graded interfaces and mechanically compatible ...

Polymer Interface Enables Reversible Quasi‐Solid Sulfur Conversion in Sodium‐Sulfur Batteries

Advanced Functional Materials, EarlyView.
The polymer interface enables a stable quasi‐solid sulfur conversion pathway in room‐temperature Na─S batteries. The coating regulates Na+ transport, stabilizes the cathode–electrolyte interphase, and accommodates mechanical stress, suppressing electrolyte decomposition and sulfur migration, thereby improving reaction uniformity, reducing polarization,
