Improved reliability and mechanical performance of Sn58Bi solder alloys

Ren, Guang; Collins, Maurice N. (MDPI, 2019)

Microstructural and mechanical properties of the eutectic Sn58Bi and micro-alloyed Sn57.6Bi0.4Ag solder alloys were compared. With the addition of Ag micro-alloy, the tensile strength was improved and this is attributed ...
Influence of gamma and electron beam sterilization on the stability of a premixed injectable calcium phosphate cement for trauma indications

Murray, Kieran A.; Collins, Maurice N.; O'Sullivan, Regina P.; Ren, Guang; Devine, Declan M.; Murphy, Alan; Sadło, Jaroslaw; O'Sullivan, Carol; McEvoy, Brian; Vrain, Oliver; O'Neill, Catriona; Insley, Gerard (Elsevier, 2018)

Premixed calcium phosphate cements (CPC's) are becoming the material of choice for injectable cements as a result of their effective delivery to the target implantation site. For orthopaedic use, it is of vital importance ...
The influence of surface roughness on the flow fields generated by an oscillating cantilever

Conway, Ciaran; Punch, Jeff (EDP Sciences, 2018)

With the current trend of miniaturisation of electronic devices, piezoelectric fans have attracted increasing interest as a means of inducing forced convection cooling, instead of traditional rotary solutions. Although ...
The influence of surfactants on capillary driven flow in open hydrophobic microchannels towards chip-based fluorescent detection of HSV

O'Leary, Fiachra (University of Limerick, 2011)

Herpes Simplex Virus (HSV) is widespread among the human population. HSV infection can have subtle symptoms and often go undiagnosed. There are two types of HSV infections. HSV type 1 (HSV-1) is associated with orofacial ...
An investigation of the fabrication and characterisation of nanocomposite thermal interface materials

Munari, Alessio (University of Limerick, 2011)

Contemporary electronic devices such as microprocessors feature high component-level heat-fluxes and tight temperature constraints. Thermal interface materials (TIMs) are a critical element in the path for heat transfer ...
On the development of a microfluidic instrument for preclinical cell analysis

Keays, Catherine Marie (University of Limerick, 2017)

The evolution of a new drug is initiated by testing new compounds in a preclinical laboratory setting. The methods for discovering new drugs involve scrutiny of a drug’s efficacy on a cell model of a disease. Current ...
On the heat transfer characteristics of liquid-gas taylor flows in minichannels

Howard, James A (University of Limerick, 2013)

Heat transfer enhancement is of significant importance to many thermal management applications. Multi phase flows are an effective way to meet increasing thermal demands. This work investigates heat transfer enhancement ...
On the influence of ag content on the creep behaviour of sn-ag-cu solder alloys

Burke, Cillian (University of Limerick, 2013)

This thesis presents an investigation of the influence of silver content on the creep behaviour of ternary tin-silver-copper (SAC) solder alloys. To this end, the creep behaviour of Sn98.5Ag1.0Cu0.5 (SAC105) solder alloy ...
On the thermal and fluidic characteristics of steam condensation in an air-cooled condenser

O'Donovan, Alan (University of Limerick, 2015)

With anthropogenic climate change being one of the dominant socio-economic topics of the last decade, renewable energy has benefited from policies and legislation limiting carbon emissions. The technologies to exploit ...
On the thermal and hydrodynamic characteristics of liquid-liquid Taylor flows

Mac Giolla, Eain Marc (University of Limerick, 2014)

Two phase liquid-liquid flows offer significant heat and mass transfer enhancements over single phase flows and, as a result, have found use in numerous emerging technologies employing microfluidics. Such technologies ...
On the use of entropy to predict boundary layer stability

Walsh, Ed J.; Davies, Mark; McEligot, Donald M (MDPI, 2004)

Boundary layer transition is a critical parameter in the design of fluid flow systems. This situation is due to the dramatic change in both entropy production and heat transfer that accompanies it. It is well recognized ...
An optical counting technique with vertical hydrodynamic focusing for biological cells

Chiavaroli, Stefano; Newport, David; Woulfe, Bernie (American Institute of Physics, 2010)

A barrier in scaling laboratory processes into automated microfluidic devices has been the transfer of lab based assays: where engineering meets biological protocol. One basic requirement is to reliably and accurately ...
Scaffold fabrication technologies and structure/function properties in bone tissue engineering

Collins, Maurice N.; Ren, Guang; Young, Kieran; Pina, S.; Reis, Rui L.; Oliveira, J. Miguel (Wiley, 2021)

Bone tissue engineering (BTE) is a rapidly growing field aiming to create a bio functional tissue that can integrate and degrade in vivo to treat diseased or damaged tissue. It has become evident that scaffold fabrication ...
A setup for gas mass flow rate measurement in T-shaped micro channel

Li, Y.; Barrot, C.; Baldas, Lucien; Colin, S.; Newport, David (2011)

A setup for mass flow rate measurement was developed for gas flow in T-shaped microchannels. Experiments with N2 were made on the test bench for the following purposes: 1) to test leakages and outgassing of the system, 2) ...
Shock pulse shaping in a small-form factor velocity amplifier

Kelly, Gerard; Punch, Jeff; Goyal, Suresh; Sheehy, Michael (Hindawi Publishing Corporation, 2010)

This theme of this paper is the design and characterisation of a velocity amplifier (VAMP)machine for high acceleration shock testing of microscale devices. The VAMP applies multiple sequential impacts to amplify velocity ...
Tailoring crystal size distributions for product performance, compaction of paracetamol

Keshavarz, Leila; Pishnamazi, Mahboubeh; Khandavilli, U.B. Rao; Shirazian, Saeed; Collins, Maurice N.; Walker, Gavin M.; Frawley, Patrick J. (Elsevier, 2021)

Paracetamol crystals often exhibit poor compressibility properties, which results in capping issues. The Particle Size Distribution (PSD) of paracetamol was engineered to improve the compressibility of paracetamol crystals. ...
The thermal and hydrodynamic behaviour of submerged and confined, normally-impinging, laminar slot jets

Sexton, Andrew (University of Limerick, 2017)

Optical networks are a critical element of contemporary communications infrastructure, due to their efficacy in transmitting high-speed data over large distances. Photonic integrated circuits (PICs) offer compelling ...
Thermal management of portable biomedical vaporisers

Kelly, Emma (University of Limerick, 2012)

This thesis presents the thermal characterisation of a gas powered, portable device used for the vaporisation of herbal materials for biomedical inhalation. The main aims of this research are to characterise the thermal ...
Thermal performance characteristics of integrated cooling solutions consisting of multiple miniature fans

Stafford, Jason; Fortune, F.; Newport, David (IOP Publishing, 2012)

Thermal performance characteristics are assessed for multiple miniature axial fans of 24.6 mm diameter that provide impingement cooling on a finned surface. Combined experimental and numerical analyses indicate that fans ...
