Micro- and nano-structural details of a spider's filter for substrate vibrations: relevance for low-frequency signal transmission
TLDR
The metatarsal lyriform organ of the Central American wandering spider Cupiennius salei is its most sensitive vibration detector and it is shown that large tarsal deflections cause large deformation in the distal highly hydrated part of the pad. Expand
A spider's biological vibration filter: micromechanical characteristics of a biomaterial surface.
TLDR
The micromechanical properties of the cuticular pad biomaterial are investigated in search of a deeper understanding of its impact on the function of the vibration sensor in a strain-sensing lyriform organ of a Central American wandering spider. Expand
Self-similar mesostructure evolution of the growing mollusc shell reminiscent of thermodynamically driven grain growth
TLDR
The three-dimensional structure of the calcite-based prismatic layer of Pinna nobilis, the giant Mediterranean fan mussel, is analysed using high-resolution synchrotronbased microtomography and it is shown that the evolution of the layer is statistically self-similar and its morphology and mesostructure can be fully predicted using classicalmaterials science theories for normal grain growth.

Structural and mechanical properties of the arthropod cuticle: comparison between the fang of the spider Cupiennius salei and the carapace of American lobster Homarus americanus.
TLDR
Material properties and structural organization of two types of cuticle from distantly related arthropods, the wandering spider Cupiennius salei and American lobster Homarus americanus were studied using nanoindentation and X-ray diffraction. Expand
Hierarchical Calcite Crystals with Occlusions of a Simple Polyelectrolyte Mimic Complex Biomineral Structures
Biominerals are complex inorganic-organic structures that often show excellent mechanical properties. Here a bio-inspired study of a remarkably simple synthetic system is presented in which only oneExpand
Nano-scale modulus mapping of biological composite materials: Theory and practice
Abstract The mechanical behavior of materials depends to a large extent on their properties at the nanoscale and, therefore, novel characterization techniques with sub-micron spatial resolution wereExpand
Materials Nanoarchitecturing via Cation-Mediated Protein Assembly: Making Limpet Teeth without Mineral.
TLDR
A nanocomposite structure hierarchically assembled to form a versatile damage-tolerant protein-based tooth, with a stiffness similar to mineralized mammalian bone, but without any mineral is revealed. Expand
Characterizing moisture-dependent mechanical properties of organic materials: humidity-controlled static and dynamic nanoindentation of wood cell walls
Nanoindentation is an ideal technique to study local mechanical properties of a wide range of materials on the sub-micron scale. It has been widely used to investigate biological materials in the dryExpand
Shaping highly regular glass architectures: A lesson from nature
TLDR
It is demonstrated that the branching of the filament follows specific crystallographic directions of the protein lattice, which determines the highly regular morphology of the spicules on the macroscale. Expand
Processing of dense bulk MgB2 superconductor via pressure-assisted thermal explosion mode of SHS
Abstract Bulk MgB 2 superconductor was synthesized from elemental Mg–B blends employing Reactive Forging (RF)—thermal explosion mode of Self-propagating High-temperature Synthesis (SHS)—under aExpand
