Composite hydrogel-nanofibre vessels for vascular graft applications
A vascular graft should mimic the structure and properties of the native artery which has a layered structure. The media layer of native arteries contributes the main mechanical support to the vessel and the intima layer, lined with endothelial cells, provides a smooth antithrombogenic surface for …

Shear-Spun Polymer Nanofibres For Water Purification
… a solution to this issue in the form of polymer nanofibres, a material that was hitherto prohibitively expensive. The studies presented in this thesis explored a novel method of synthesising polymer nanofibres that is capable of large-scale manufacture (done entirely using low-cost materials), …

Optical micro- and nanofibres: Higher mode generation and particle manipulation studies
… on two experimental fields of optical micro- and nanofibre research; higher mode generation/excitation and evanescent field optical manipulation. Standard, commercial, single-mode silica fibre is used throughout most of the experiments; this generally produces high-quality, single-mode, micro- or …

Water stable, antimicrobial active nanofibres generated by electrospinning from aqueous spinning solutions
… about the development of antimicrobial active nanofibres. The objective was to generate these nanofibres from aqueous spinning solutions via electrospinning. By this, organic solvents were avoided so that electrospinning was performed at environmentally friendly conditions. Electrospinning of …

Modelling and Exploiting the Hyperfine Structure of Alkali Atoms for Generation of Nonclassical Light and Rydberg-Atom-Based Field Sensing
… through specific configurations of single- atom nanofibre cavity QED systems. By coupling an alkali atom to nanofibre cavity modes, we demonstrate antibunching and strong two-mode correlations, showcasing the versatility of these systems for generating nonclassical photon statistics. We consider …

Amphiphilic block copolymers as templates for particle formation and positioning
… patterns on flat surfaces as well as in polymer nanofibre structures. Three different types of amphiphilic block copolymers, polystyrene-b-poly(2-vinylpyridine), polyisoprene-b-poly(2-vinylpyridine) and poly(butadiene)-b-poly(ethylene oxide), were synthesized by living anionic polymerisation and …
