Manufacturing strategy for high current cold field emission cathodes: Floating catalyst chemical vapour deposition grown carbon nanotube fibres and films enhanced by laser patterning and laser purification process
… a particular focus on the relationship of the laser time pulse duration used for cutting CNTs and how this affects the field emission performance. Material selection for this work was narrowed to CNT as they possess unique characteristics such as: high aspect ratio; high thermal conductivity; …

Designing a Hybrid Inkjet and Laser Manufacturing System for the Digital and Non-Contact Fabrication of Emerging Nanotechnology Based Devices
… magnetite nanoparticles as catalyst, and laser ablation has been studied as a subtractive technique to pattern the catalyst for growing VA-CNT structures, using chemical vapour deposition as an assistive growth procedure. The research was conducted in three phases. In the feasibility phase …

Three-Dimensional Biomimetic Patterning to Guide Cellular Migration and Organization
This thesis develops a novel photopatterning strategy for biomimetic scaffolds that enables spatial and biochemical control of engineered cellular architectures, such as the microvasculature. Intricate tools that allow for the three dimensional (3D) manipulation of biomaterial microenvironments …

Laser assisted nano-optics processing in optical data storage
… optical lithography techniques, microlens array laser patterning and near-field scanning optical lithography, are presented to show their capabilities in nanostructures fabrication. Laser irradiation through microlens array is used to create nanostructures on phase-change films over a large area. …

Capacitive Touchscreen Sensors for the Measurement of Ions in Electrolytes
… touchscreen-inspired ITO sensors using standard laser-cutter equipment. The fabricated devices show more than double the sensitivity for measuring aqueous samples compared to the commercial touchscreen. Interdigital comb structures increase the sensitivity further from 4.0 to 8.8 compared to a …
