Alleged primitive feathers or protofeathers in the theropod dinosaur Sinosauropteryx have potentially profound implications concerning feather morphogenesis, evolution offlight, dinosaur physiology and perhaps even the origin of birds, yet their existence has never been adequately documented. We report on a new specimen of Sinosauropteryx which shows that the integumental structures proposed as...

The aim of this study was to fabricate a fibrous scaffold that closely resembled the micro-structural architecture and mechanical properties of collagen fibres found in the anterior cruciate ligament (ACL). To achieve this aim, fibrous scaffolds were made by electrospinning L-lactide based polymers. L-Lactide was chosen primarily due to its demonstrated biocompatibility, biodegradability and hi...

The superminimality of the fibres of an almost contact metric submersion is used to study the integrability of the horizontal distribution and the structure of the total space.

Depending both on structure and properties of the starting carbonaceous material, fluorination conditions, fluorine can bond to carbon fibres in various ways. This review aims investigate versatility C-F bonding its influence fibre properties. Morphology surface properties, such as diameter, Scanning Electron Microscopy observations, specific area, wettability acidity are discussed according co...

Distributed measurements of the Brillouin gain spectrum in a photonic crystal fibre have been carried out for the first time to our knowledge. These measurements confirm the strong increase of the Brillouin threshold as resulting from the broadband and multimode nature of the Brillouin gain spectrum all along the fibre. INTRODUCTION The periodic wavelength-scale air-hole microstructure of solid...

The mechanical stability of the culms of monocotyledonous bamboos is highly attributed to the proper embedding of the stiff fibre caps of the vascular bundles into the soft parenchymatous matrix. Owing to lack of a vascular cambium, bamboos show no secondary thickening growth that impedes geometrical adaptations to mechanical loads and increases the necessity of structural optimization at the m...

Structural batteries consist of carbon fibres embedded in a porous structural battery electrolyte (SBE), which is composed two continuous phases: solid polymer skeleton and liquid containing Li-salt. In this paper we elaborate on computational modelling framework to study the electro-chemo-mechanical properties such while accounting for combined action from migration as well stress-assisted dif...

Spiders store spidroins in their silk glands as high concentration aqueous solutions, spinning these dopes into fibres with outstanding mechanical properties. Aciniform (or wrapping) silk is the toughest spider silk and is devoid of the short amino acid sequence motifs characteristic of the other spidroins. Using solution-state NMR spectroscopy, we demonstrate that the 200 amino acid Argiope tr...
