Toughness amplification in natural composites
Abstract Natural structural materials such as bone and seashells are made of relatively weak building blocks, yet they exhibit remarkable combinations of stiffness, strength and toughness. ThisExpand
FATTY ACIDS, AMINO ACIDS, MINERAL CONTENTS, AND PROXIMATE COMPOSITION OF SOME BROWN SEAWEEDS 1
This study was conducted to create a nutritional database on brown seaweeds and to popularize their consumption and utilization in Iran. The fatty acid contents, amino acids profiles, and certainExpand
Failure mode transition in nacre and bone-like materials.
Mineralized biological materials such as nacre or bone achieve remarkable combinations of stiffness and toughness by way of staggered arrangements of stiff components (nanoscale or microscale fibersExpand
The weak interfaces within tough natural composites: experiments on three types of nacre.
Mineralization is a typical strategy used in natural materials to achieve high stiffness and hardness for structural functions such as skeletal support, protection or predation. High mineral contentExpand
Insertion profiles of 4 headless compression screws.
PURPOSE In practice, the surgeon must rely on screw position (insertion depth) and tactile feedback from the screwdriver (insertion torque) to gauge compression. In this study, we identified theExpand
An improved failure criterion for biological and engineered staggered composites
High-performance biological materials such as nacre, spider silk or bone have evolved a staggered microstructure consisting of stiff and strong elongated inclusions aligned with the direction ofExpand
The National Programme for IT in England: Clinicians’ views on the impact of the Choose and Book service
TLDR
In England, the Choose and Book service, a main component of the England National Programme for IT (NPfIT), aims at empowering patients. Expand
Structure, Scaling, and Performance of Natural Micro- and Nanocomposites
Natural materials boast remarkable mechanical performances in some cases unmatched by their synthetic counterparts, and for this reason, they have become an inspiration for the development of newExpand
THE CHECKLIST OF GREEN ALGAE OF THE IRANIAN COASTAL LINES OF THE PERSIAN GULF AND GULF OF OMAN
In this checklist 62 species of marine green algae (Chlorophyta) are reported from Iranian coastal lines of Persian Gulf and Oman Gulf. This list represents a summary of 9 scietific papers publishedExpand
Productivity, biochemical composition and biofiltering performance of agarophytic seaweed, Gelidium elegans (Red algae) grown in shrimp hatchery effluents in Malaysia
Aquaculture systems may release large amounts of nutrients into the marine ecosystem that can lead to eutrophication. Many seaweed species are efficient in reducing the nutrient concentration inExpand
