  • Rice, Daragh; Mouras, Rabah; Gleeson, Matthew; Liu, Ning; Tofail, Syed A.M.; Soulimane, Tewfik; Silien, Christophe (American Chemical Society, 2018)
    Noble-metal nanoparticles size and packing density are critical for sensitive surface-enhanced Raman scattering (SERS) and controlled preparation of such films required to achieve reproducibility. Provided that they are ...
  • Poudel, Anup; Fernandez, Marc A.; Tofail, Syed A.M.; Biggs, Manus J.P. (University of Nebraska Press, 2019)
    Analysis of the cellular response to piezoelectric materials has been driven by the discovery that many tissue components exhibit piezoelectric behavior ex vivo. In particular, polyvinylidene fluoride and the trifluoroethylene ...
  • Butler, James (University of Limerick, 2011)
    This thesis details the results obtained from an extensive study on the development of a workable radiopaque rare earth doped NiTi alloy through a traditional ingot melting (IM) route and a powder metallurgy (PM) route. ...
  • Kumbham, Mahendar; Daly, Susan; O'Dwyer, Kevin; Mouras, Rabah; Liu, Ning; Mani, Aladin; Peremans, André; Tofail, Syed A.M.; Silien, Christophe (Optical Society of America, 2016)
    The spatial resolution in far-field mid-infrared (λ>2.5 μm) microscopy and microspectroscopy remains limited with the full-width at half maximum of the point-spread function ca. λ/1.3; a value that is very poor in ...
  • Zhang, Yugi (University of Limerick, 2012)
    The mechanical and electromechanical behaviour of bone such as elasticity and piezoelectricity have long been considered to be a consequence of its hierarchical architecture, the basic building block of which, at the ...
  • Silien, Christophe; Liu, Ning; Hendaoui, Nordine; Tofail, Syed A.M.; Peremans, André (Optical Society of America, 2012)
    A framework is proposed for infrared (IR) absorption microscopy in the far-field with a spatial resolution below the diffraction limit. The sub-diffraction resolution is achieved by pumping a transient contrast in the ...
  • Pita, Isabel A.; Hendaoui, Nordine; Liu, Ning; Kumbham, Mahendar; Tofail, Syed A.M.; Peremans, André; Silien, Christophe (Optical Society of America, 2013)
    Although confocal infrared (IR) absorption micro-spectroscopy is well established for far-field chemical imaging, its scope remains restricted since diffraction limits the spatial resolution to values a little above half ...
  • Cronin, Patrick (University of Limerick, 2012)
    The incorporation of nanoparticles (NPs) into the surfaces of materials has received significant attention, especially in the area of textiles for self-cleaning. The sphericity and fast oxidation of metallic NPs when exposed ...
  • Alvarez, Marcela Salazar; Korostynska, Olga; Mason, Alex; Al Ahamma'a, Ahmed; Cooney, Jakki C.; Magner, Edmond; Tofail, Syed A.M. (Royal Society of Chemistry, 2014)
    The specific binding of streptavidin to biotinylated protein A was demonstrated using a microwave detection system. In control experiments, the degree of non-specific binding was negligible. The method of detection was ...
  • O'Dwyer, Kevin (University of Limerick, 2018)
    Many typical methods of studying particles within an aqueous solution use some form of control mechanism to limit sample variability. A common application in cytometry is the use of hydrodynamic focusing to confine the ...
  • Twohig, Eoghan (University of Limerick, 2012)
    The traditional process of metallic wire and rod production pulls a wire/rod through a die to reduce its diameter in successive steps. The considerable die wear at the tool-die interface coupled with the additional lubrication ...
  • Koumoulos, Elias P.; Tofail, Syed A.M.; Silien, Christophe; De Felicis, D.; Moscatelli, R.; Dragatogiannis, D.A.; Bemporad, E.; Sebastiani, M.; Charitidis, Costas A. (Elsevier, 2018)
    Nanometrology refers to measurement techniques that assess materials properties at the nanoscale. Laboratorybased characterisation of nanomaterials has been the key enabler in the growth of nanotechnology and nanoenable ...
  • Karimi-Jafari, Maryam (University of Limerick, 2016)
    Barium titanate is one of the most important and widely studied ferroelectric ceramics with ABO3 type perovskite structure. Due to its promising ferroelectric properties, it has been used in several applications such as ...
  • Pastorino, Laura; Dellacasa, Elena; Noor, Mohamed R.; Soulimane, Tewfik; Bianchini, Paolo; D’Autilia, Francesca; Antipov, Alexei; Diaspro, Alberto; Tofail, Syed A.M.; Ruggiero, Carmelina (Public Library of Science, 2014)
    Cell-sized polyelectrolyte capsules functionalized with a redox-driven proton pump protein were assembled for the first time. The interaction of polyelectrolyte microcapsules, fabricated by electrostatic layer-by-layer ...
  • Guerin, Sarah; Tofail, Syed A.M.; Thompson, Damien (Springer, 2019)
    Research on the piezoelectric response of biomolecules has intensified following demonstration of open circuit voltages of over 20 V in biopiezoelectric generators. Organic piezoelectric nanotubes, fibers, and micro-islands ...
  • Stapleton, Aimee; Noor, Mohamed R.; Haq, Ehtsham U.; Silien, Christophe; Soulimane, Tewfik; Tofail, Syed A.M. (AIP Publishing, 2018)
    Pyroelectricity is the ability of certain non-centrosymmetric materials to generate an electric chargein response to a change in temperature and finds use in a range of applications from burglar alarms to thermal imaging. ...
  • Guerin, Sarah; O'Donnell, Joseph; Haq, Ehtsham U.; McKeown, Cian; Silien, Christophe; Rhen, Fernando M.F.; Soulimane, Tewfik; Tofail, Syed A.M.; Thompson, Damien (American Physical Society, 2019)
    Single crystal L-amino acids can exhibit technologically useful piezoelectric and nonlinear optical properties. Here we predict, using density functional theory, the piezoelectric charge and strain and voltage tensors of ...
  • O'Mahony, Charlie; Ul Haq, Ehtsham; Silien, Christophe; Tofail, Syed A.M. (MDPI, 2019)
    As the industry and commercial market move towards the optimization of printing and additive manufacturing, it becomes important to understand how to obtain the most from the materials while maintaining the ability to ...
  • Kumbham, Mahendar; Mouras, Rabah; Mani, Aladin; Daly, Susan; O'Dwyer, Kevin; Toma, Andrea; Bianchini, Paolo; Diaspro, Alberto; Liu, Ning; Tofail, Syed A.M.; Silien, Christophe (Optical Society of America, 2017)
    We have experimentally investigated the enhancement in spatial resolution by image subtraction in mid-infrared central solid-immersion lens (c-SIL) microscopy. The subtraction exploits a first image measured with the c-SIL ...
