Ex Vivo Study Using Diffusion Tensor Imaging to Identify Biomarkers of Atherosclerotic Disease in Human Cadaveric Carotid Arteries
(2022)Background: This study aims to address the potential of ex vivo diffusion tensor imaging to provide insight into the microstructural composition and morphological arrangement of aged human atherosclerotic carotid ... -
Microstructural and mechanical insight into atherosclerotic plaques: an ex vivo DTI study to better assess plaque vulnerability
(2023)Non-invasive microstructural characterisation has the potential to determine the stability, or lack thereof, of atherosclerotic plaques and ultimately aid in better assessing plaques’ risk to rupture. If linked with ... -
Optimisation and 3D Printing of Paediatric Stents
(Trinity College Dublin. School of Engineering. Discipline of Mechanical & Manuf. Eng, 2023)Aortic coarctation is a congenital heart defect that occurs 3 per 10,000 live births with a life expectancy of 35 years if left untreated. Stenting is a common treatment method, but devices are not specifically designed ... -
Non-Invasive metabolic profiling in tissue engineering and innate immunology by 2P-FLIM
(Trinity College Dublin. School of Engineering. Discipline of Mechanical & Manuf. Eng, 2023)During the golden age of biochemistry from 1920s to 1960s, many of the metabolic pathways responsible for nutrient usage and energy production in humans and other organisms was defined. During this period, glycolysis, Krebs ... -
Development of an off-the-shelf biomimetic vascular graft for small diameter vascular regeneration
(Trinity College Dublin. School of Engineering. Discipline of Mechanical & Manuf. Eng, 2023)Cardiovascular disease is one of the leading causes of death worldwide. The impairment of blood flow can require a total vessel substitution, but current grafts fail to recapitulate the unique mechanical behavior of native ... -
Applying thermal post-processing techniques to engineer the microstructure and mechanical performanceof selective-laser-melted Ti-6Al-4V ELI
(Trinity College Dublin. School of Engineering. Discipline of Mechanical & Manuf. Eng, 2023)As an additive manufacturing technology, selective laser melting (SLM) affords the creation of customisable parts at high resolutions to within the micron range. Among the materials being processed by SLM systems, the ... -
Two- and three-dimensional in vitro nucleus pulposus cultures: An in silico analysis of local nutrient microenvironments
(2022)Background It is well established that the unique biochemical microenvironment of the intervertebral disc plays a predominant role in cell viability and biosynthesis. However, unless the effect of microenvironmental ... -
Rat tail models for the assessment of injectable nucleus pulposus regeneration strategies
(2022)Back pain is a global epidemiological and socioeconomic problem often associated with intervertebral disc degeneration; a condition believed to initiate in the nucleus pulposus (NP). There is considerable interest in ... -
Multi-chamber micro-perforated panel absorbers optimised for high amplitude broadband absorption using a two-point impedance method
(2023)An optimised, multi-chamber, micro-perforated panel absorber (MC-MPPA) with micro-perforated adjoining panels is presented in this paper. An MPPA is a clean and efficient noise absorber with a simple structure making it ... -
Hydrostatic pressure promotes chondrogenic differentiation and microvesicle release from human embryonic and bone marrow stem cells
(2022)Mechanical stimulation plays in an important role in regulating stem cell differentiation and their release of extracellular vesicles (EVs). In this study, effects of low magnitude hydrostatic pressure (HP) on the chondrogenic ... -
How to design, develop and build a fully-integrated melt electrowriting 3D printer
(2022)Melt electrowriting (MEW) is a high resolution material extrusion based additive manufacturing process with the unique capability to produce micron to sub-micron diameter fibres and control their deposition in three ... -
Surface Free Energy Dominates the Biological Interactions of Postprocessed Additively Manufactured Ti-6Al-4V
(2022)Additive manufacturing (AM) has emerged as a disruptive technique within healthcare because of its ability to provide personalized devices; however, printed metal parts still present surface and microstructural defects, ... -
Investigation of the effect of low-temperature annealing and impact angle on the erosion performance of nickel-tungsten carbide cold spray coating using design of experiments
(2022)This study investigates the solid particle erosion performance of cold sprayed tungsten carbide-nickel coatings using alumina particles as erodent material. After the coatings fabrication, specimens were annealed in an ... -
Systematic research on the formation of heterogenous microstructure in FeCoNiCrMn high entropy cold spray
(2022)High entropy alloys, as a novel alloy system, demonstrated excellent mechanical performance. However, despite its excellent mechanical performance, the strength-ductility trade-off effect still limit its performance. In ... -
Interparticle bonding and interfacial nanocrystallization mechanisms in cold sprayed metallic glass
