  • Evaluation of acridine in Nafion as a fluorescence-lifetime-based pH sensor 

    Ryder, Alan G.; Power, Sarah; Glynn, Thomas J. (2003)
    We report a novel fluorescence-lifetime-based pH sensing method that utilizes acridine incorporated into Nation (AcNaf) as the fluorescent indicator. The AcNaf sensor is excited using a 380 nm light emitting diode (LED) ...
  • Fluorescence lifetime based pH sensing using Resorufin 

    Ryder, Alan G.; Power, Sarah; Glynn, Thomas J. (2003)
    Accurate, non-contact pH sensing is of particular importance in the biological and clinical sciences. Fluorescence lifetime based pH sensing is potentially more useful than intensity based methods because of the reduced ...
  • A laboratory study of the expansion of an Irish pyritic mudstone/siltstone fill material 

    Sutton, David; McCabe, Bryan A.; O'Connell, Aidan; Cripps, John C. (Elsevier, 2012-11-07)
    Extensive damage to dwellings in the east of Ireland, arising from the expansive pyritic fill material used beneath the floor slabs, prompted the laboratory study presented in this paper to quantify the expansion and study ...
  • Time-domain measurement of fluorescence lifetime variation with pH 

    Ryder, Alan G.; Morrison, John J.; Power, Sarah; Glynn, Thomas J. (Society of Photo-optical Instrumentation Engineers, 2001)
    Advances in the design and miniaturization of the lasers and electronics required for Time Correlated Single Photon Counting (TCSPC) measurement of fluorescence lifetime have simplified the use of the time domain method. ...
