Bending stability of Cu0.4CrO2 - A transparent p-type conducting oxide for large area flexible electronics
(2018)The current best performing p-type transparent conducting oxides are typically highly crystalline materials, deposited at high temperatures, and hence incompatible with the drive to low cost flexible electronics. We ... -
Boronic Acid Homopolymers as Effective Polycations for Sugar-Responsive Layer-by-Layer Assemblies
(2019)Due to their reversible diol-binding ability, phenylboronic acid (BA) derivatives have gained considerable interest for the development of saccharide sensors and drug delivery systems. In particular, ... -
Deformation and Yield of Polymer Thin Films in Confined Geometries
(Trinity College Dublin. School of Physics. Discipline of Physics, 2019)Polymer thin film mechanics represents a hugely promising field of research. Due to their versatility and ease of fabrication, polymer films and coatings rank among the most ubiquitous systems in all of nanotechnology. The ... -
Development of Stimuli-responsive Materials for Direct Laser Writing for the Realisation of Microactuators
(Trinity College Dublin. School of Chemistry. Discipline of Chemistry, 2024)Two-photon polymerisation (2PP) is a laser-based fabrication technology which can be used to fabricate complex 3D microstructures with feature sizes ~100 nm. This thesis assesses the state of the art in 2PP and presents ... -
"The dominant role of the solvent-water interface in water droplet templating of polymers"
(2013)We investigate the formation of microstructured polymer networks known as Breath Figure templated structures created by the presence of water vapour over evaporating polymer solutions. We use a highly controlled experimental ... -
Effects of ions on the dielectric permittivity and relaxation rate and the decoupling of ionic diffusion from dielectric relaxation in supercooled liquid and glassy 1-propanol
(American Institute of Physics, 2002)The effects of intermolecular H bonds on the equilibrium permittivity, ?s, the relaxation rate, fm, and changes in the dielectric relaxation spectra of 1-propanol were studied by adding a strongly dissociating electrolyte ... -
The influence of additive manufacturing processes on the performance of a periodic acoustic metamaterial
(2019)Advancements in 3D print technology now allow the printing of structured acoustic absorbent materials at the appropriate microscopic scale and sample sizes. The repeatability of the fundamental cell unit of these metamaterials ... -
Phase diagrams of polymer-dispersed liquid crystal systems of itraconazole - component immiscibility induced by molecular anisotropy
(2018)Liquid crystalline (LC) materials and their nonmedical applications have been known for decades, especially in the production of displays; however, the pharmaceutical implications of the LC state are inadequately appreciated, ... -
Powder stream characteristics in cold spray nozzles
(2011)The exponential increase of industrial demand in the past two decades has led scientists to the development of alternative technologies for the fast manufacturing of engineering components, aside from ... -
The rationale and emergence of electroconductive biomaterial scaffolds in cardiac tissue engineering.
(2019)The human heart possesses minimal regenerative potential, which can often lead to chronic heart failure following myocardial infarction. Despite the successes of assistive support devices and pharmacological therapies, ... -
Responsive spiral photonic structures for visible vapor sensing, pattern transformation and encryption
(2023)Two photon polymerisation using direct laser writing is a burgeoning field of research, with recent focus being placed on bringing added value to microstructures, by incorporating soft, responsive polymers. Moving to the ... -
A structurally versatile coordination polymer: demonstrating spontaneous resolution, conformational polymorphism and gel formation
(2013)Conformationally flexible C2-symmetric 2-(2?-cyanophenoxy) benzonitrile (O,O-CPBN) was self-assembled using silver ions into spontaneously resolved, helical and coordination polymer gel structures including unprecedented ... -
Sub-15nm silicon lines fabrication via PS-b-PDMS block copolymer lithography
(Hindawi Publishing Corp., 2013)This paper describes the fabrication of nanodimensioned silicon structures on silicon wafers from thin films of a poly(styrene)-block-poly(dimethylsiloxane) (PS-b-PDMS) block copolymer (BCP) precursor self-assembling into ... -
