Steel fibres are used in high amounts high-performance steel fibre reinforced cementitious composite (HPSFRCCs) and ultra-high-performance (UHPSFRCCs) to enhance its structural performance. Due the amount randomly distribution of matrix a level damage aesthetic mechanical response may be expected for structures under chloride exposition. This work aims assess behaviour uncracked HPSFRCCs...

Three novel Bouligand inspired composites were produced by vacuum bag infusion manufacturing process and their quasi-static mechanical performance compared to a conventional aircraft laminate. A morphologic/physical study was first conducted for all configurations response under tensile, three-point bending (3-PB) interlaminar shear strength (ILSS) tests then evaluated discussed. No significant...

Bi₂Se₃ initially emerged as a particularly promising host of topological physics. However, in actual materials, several issues have been uncovered including strong surface band bending and potential fluctuations. To investigate these concerns, we study nominally stoichiometric Bi₂Se₃ using scanning tunnelling microscopy. Here we identify two distinct distributions of BiSe antisites that act as ...

The cilia and flagella of eukaryotic cells function by active bending that produces cell movements and fluid flows in their environment. They contain a common cytoskeleton, known as the axoneme, that is the locus of all the enzymes and mechanical components that are required for production of useful bending. The bending of many flagella, and some cilia, is planar, or at least nearly planar. In ...
