Towards Fibre-Integrated Hydrogels: A New Approach for 3D Hydrogel Printing & A Study of Single Cell-Microfibre Interactions
… grid fibre patterns made of polystyrene. With microfibres deposited onto non-passivated surfaces, cells were able to dynamically adapt their shapes in response to the directly-adhered fibre, as well as to the neighbouring patterns; and such adaptation reflect their ability to shuttle and alter …

Settling Velocity of Straight and Curved Rods at Low Reynolds Numbers in a Quiescent Fluid
… is aimed towards understanding the effects of microfibre geometry on the settling velocity. Microfibres have been mathematically modelled as simple straight rods in the past to estimate their settling velocity; however, samples collected demonstrate complex geometries. One common geometric …

Quantifying land-based sources of plastic pollution in South Africa
… urbanised upper reaches of the Vaal River, while microfibres were particularly abundant in the arid, sparsely populated lower reaches of the Orange River at the end of the wet season. It therefore appears that the Orange-Vaal River system may be a source of microfibres to the Atlantic Ocean, but …

Delivery of hiPSC Derived Cardiomyocytes via an Injectable Nanofibrous Gelatin Polyurethane Composite Scaffold for Heart Tissue Repair
… benefits of delivering cells pre-adhered to microfibre sheets, and injected on biomaterial carriers, with the ability to provide immediate cell-substrate adhesion and the potential for establishing cell-cell communication, and thereby contributing to cell survival for cardiac cell therapy.

Low Reynolds Number Settling of Cylindrical Rods with Various Geometries in a Quiescent Fluid
… a major pathway for the long-range transport of microfibres. However, many atmospheric simulations simplify fibre geometry, often representing them as volume-equivalent spheres or straight cylinders, despite the more complex shapes observed in microfibre samples from atmospheric deposits. This …

Isolation, growth and epidemiology of campylobacter jejuni / coli
… as 10 campylobatters/tOO ml of water. A glass microfibre filtration system was even more sensitive. A blood-free non-selective agar (BFNSA) containing charcoal (0.4%), ferrous sulphate (0.025%) and sodium pyruvate (0.025%) was also developed. These supplements were shown to detoxify rather than …

PEDOT:PSS Fibre Building Blocks for Adaptive and Sustainable Bioelectronic Structures
… technique for functionalising thermoplastic microfibre core, which achieved μL-level downscaled coating solution batch sizes and sub-mm multi-layer coating length control for improved customisability at low power. The produced fibres are individually handleable, embodying multimodal sensing …

Characterisation and development of carbon nanotube macrostructures
… to prevent this effect. Mechanical testing of microfibres has been performed to observe how the mechanical response of these fibres is linked to the structure of the CNTs in the fibre (chapter 4). The fracture zone of microfibres displays similarities to fibrous composites, with nanofibrils …

Adaptive fabrication of biofunctional decellularized extracellular matrix niche towards complex engineered tissues
… properties. This scaffold, formed by microfibres, displays three favorable characteristics as a cell culture platform: high-loading of key ECM proteins, single-layered mesh membrane with controllable mesh size, and flexibility for supporting a range of cell culture configurations. …

Investigation of alternative carbon sources for the biological treatment of synthetic sulphate-laden water and mine impacted water in a linear flow channel reactor
… flow and enhanced contacting and the carbon microfibre biomass support was replaced with polyurethane foam (PUF) previously shown to effect efficient biomass retention. A secondary reactor was included to provide 30% of operating volumes with no baffles; it was connected in series to increase …
