A Biologically‐Architected Wear and Damage‐Resistant Nanoparticle Coating From the Radular Teeth of Cryptochiton stelleri

Advanced Functional Materials, EarlyView.
The ultrahard teeth of mollusks that feed on rocky substrates contain a wear‐resistant coating on their surfaces consisting of densely packed mesocrystalline magnetic nanoparticles within an organic matrix. These coatings display significant hardness and toughness through their highly controlled mesocrystalline architectures.

The Effects of Sintering Temperature on Densification and Mechanical Properties of Hydroxyapatite/Sodium Alginate Biocomposites

MATEC Web of Conferences, 2017
Hydroxyapatite (HA) has been studied for their excellent performances which are suitable for use in bone defects or regeneration of bone. Hydroxyapatite (HA) has poor mechanical properties which make it limited used in a load bearing area.

Bio‐Inspired Nanoarchitected LiFePO4 Cathodes

Advanced Functional Materials, EarlyView.
Lithium iron phosphate (LFP) is synthesized using a bio‐inspired method, using acidic macromolecules similar to those found in many calcareous mineralized organisms to modulate the morphology and crystal growth of LFP‐carbon composite particles. The observations from this process indicate a non‐classical crystallization process, which subsequently ...

Effect of fish oil on lipopolysaccharide-induced hydroxyapatite loss in rat alveolar bone: A Preliminary Study [PDF]

, 2009
Dietary fish oil has been shown to inhibit bone resorption and, therefore, the aim of the present study was to test the hypothesis that fish oil alters lipopolysaccharide (LPS)-induced hydroxyapatite loss in rat alveolar bone. Rats were divided into four

SINTESIS DAN UJI POROSITAS SCAFFOLD HIDROKSIAPATIT/ALGINAT

ODONTO: Dental Journal, 2018
Background: In bone tissue engineering, scaffold is required with a large porosity of 80-90%. The porosity of the hydroxyapatite/alginate scaffold can be affected by the alginate concentration used.

Structural Porosity and Low Mineral Density in Enamel Rods Drive Molar Incisor Hypomineralisation

Advanced Functional Materials, EarlyView.
This study uses advanced imaging modalities on multiple length scales to show that molar‐incisor hypomineralization does not present as a locally homogeneous pathology. Instead, microstructural defects, characterized through non‐mineralized, protein‐rich sheaths and an altered mineral structure in between prism rods, resulting in local differences in ...

Calcium-deficient Hydroxyapatite as a Potential Sorbent for Strontium

Scientific Reports, 2017
A calcium (Ca)-deficient hydroxyapatite was investigated for its potential to remove Sr2+ from environmentally relevant water. We conducted sorption tests on solutions containing magnesium ion (Mg2+) and calcium ion (Ca2+) as competing cations at a ...

Micro and Nanostructural Diversity of Lizard Osteoderm Capping Tissue in Relation to Mechanical Performance

Advanced Functional Materials, EarlyView.
This study shows that lizard osteoderm capping tissue is a hyper‐mineralized hydroxyapatite layer consistently covering the superficial osteoderm surface in those species studied here, yet it varies greatly in morphology, nanostructure, and mechanical performance across species.
