Molecular mechanistic origin of the toughness of natural adhesives, fibres and composites
Natural materials are renowned for their strength and toughness,,,,. Spider dragline silk has a breakage energy per unit weight two orders of magnitude greater than high tensile steel,, and is
Molecular Cloning and Characterization of Lustrin A, a Matrix Protein from Shell and Pearl Nacre of Haliotis rufescens *
TLDR
The cDNA coding for Lustrin A, a newly described matrix protein from the nacreous layer of the shell and pearl produced by the abalone, Haliotis rufescens, a marine gastropod mollusc, is cloned and characterized.
Virus-Enabled Synthesis and Assembly of Nanowires for Lithium Ion Battery Electrodes
TLDR
Combining virus-templated synthesis at the peptide level and methods for controlling two-dimensional assembly of viruses on polyelectrolyte multilayers provides a systematic platform for integrating these nanomaterials to form thin, flexible lithium ion batteries.
Bacterial biosynthesis of cadmium sulfide nanocrystals.
Selection of peptides with semiconductor binding specificity for directed nanocrystal assembly
TLDR
It is shown that combinatorial phage-display libraries can be used to evolve peptides that bind to a range of semiconductor surfaces with high specificity, depending on the crystallographic orientation and composition of the structurally similar materials the authors have used.
Control of crystal phase switching and orientation by soluble mollusc-shell proteins
IN the initial stages of the biomineralization of abalone shells, a primer layer of oriented calcite crystals grows on a nucleating protein sheet1,2. The deposition of this primer is followed by an
Kinesin's cover-neck bundle folds forward to generate force
TLDR
A stepping mechanism driven by dynamic cover-neck bundle formation is supported and a strategy to generate motors with altered mechanical characteristics by targeting the force-generating element is suggested.
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
Ordering of Quantum Dots Using Genetically Engineered Viruses
TLDR
A liquid crystal system was used for the fabrication of a highly ordered composite material from genetically engineered M13 bacteriophage and zinc sulfide nanocrystals, which spontaneously evolved a self-supporting hybrid film material.
Virus-Based Toolkit for the Directed Synthesis of Magnetic and Semiconducting Nanowires
TLDR
The unique ability to interchange substrate-specific peptides into the linear self-assembled filamentous construct of the M13 virus introduces a material tunability that has not been seen in previous synthetic routes, and provides a genetic toolkit for growing and organizing nanowires from semiconducting and magnetic materials.
