    High-density, ordered arrays of germanium nanowires have been synthesised within the pores of mesoporous thin films (MTFs) and anodized aluminium oxide (AAO) matrices using a supercritical fluid solution-phase inclusion ...
  • Contribution of process parameters to the particle size distribution and apparent viscosity properties of soy protein isolate- and hydrolysate-based infant formula emulsions
    McEvoy, Emma Marie (University of Limerick, 2005)
    Oil-in-water emulsions were manufactured with commercially available soy protein isolate (SPI 1500 and SPI 1651) and soy protein hydrolysate (SPH 1761 and SPH 1762) ingredients. In addition to SPIISPH, the model emulsions ...
  • Core materials for high frequency VRM inductors
    Kelly, Sean; Collins, Christina; Duffy, Meave; Rhen, Fernando M.F.; Roy, Saibal (IEEE Computer Society, 2007)
    The application of PCB integrated electroplated cores for VRM inductors is proposed, where the motivation is to increase frequencies beyond 1 MHz so that VRM transient response can be improved. It is shown that electroplated ...
  • ECM-based materials in cardiovascular applications: inherent healing potential and augmentation of native regenerative processes
    Piterina, Anna V.; Cloonan, Aidan J.; Meaney, Claire L.; Davis, Laura M.; Callanan, Anthony; Walsh, Michael T.; McGloughlin, Timothy M. (MDPIAG, 2009)
    The in vivo healing process of vascular grafts involves the interaction of many contributing factors. The ability of vascular grafts to provide an environment which allows successful accomplishment of this process is ...
  • Electrodeposited CoNiFeP soft-magnetic films for high-frequency applications
    Rhen, Fernando M.F.; Roy, Saibal (IEEE Computer Society, 2008)
    We have studied the influence of P and of plating current density on static/dynamic magnetic and electrical properties of CoNiFe high moment alloy. We found that morphology, electrical and magnetic properties of films with ...
  • Enhancing the role of the interfaces in software architecture description languages (ADLs)
    Galvin, Seamus; Collins, J.J.; Exton, Chris; McGurren, Finbar (Springer, 2004)
    One of the key reasons why ADLs are yet to be adopted commercially on a large scale is due to shortcomings in their ability to describe adequate interface specifications. An interface specification that is vague, lacking ...
  • Formulation of epoxy-polyester powder coatings containing silver-modified nanoclays and evaluation of their antimicrobial properties
    Armstrong, Gordon; Thornton, Roibeard; Ryan, Michael P; Laffir, Fathima; Russell, Ronald J; Bala, Tanushree; Keely, Christopher; Babu, Rameesh (Springer-Verlag, 2012)
    Current interest in antimicrobial coatings is driven by an urgent need for more effective strategies to control microbial infection. In this study, antimicrobial nanoclays were prepared by ion-exchange of sodium montmorillonite ...
  • High current inductor design for MHz switching
    Duffy, Meave; Collins, Christina; Rhen, Fernando M.F.; McCloskey, P.; Roy, Saibal (IEEE Computer Society, 2008)
    High current inductor applications operating in the MHz range are generally limited to Voltage Regulator Modules (VRM’s) and Point of Load (POL) power supplies, where the issue of fast transient response demands reduced ...
  • Insights into the mode of action of a putative zinc transporter CzrB in thermus thermophilus
