Publication Analysis of crude petroleum oils using fluorescence spectroscopy.(Springer, 2005) Ryder, Alan G.Crude oil is defined as a mixture of hydrocarbons that existed in the liquid phase in natural underground reservoirs and remains liquid at atmospheric pressure after passing through surface separating facilities (joint American Petroleum Institute, American Association of Petroleum Geologists, and Society of Petroleum Engineers definition).1 Crude petroleum oils are complex mixtures of different compounds (mainly organic), which are obtained from an extensive range of different geological sources.2,3 Their physical appearance can vary from solid black tars to almost transparent liquids. In their natural state within an oilfield reservoir or entrapped within Hydrocarbon bearing Fluid Inclusions (HCFI), crude oils will also contain varying amounts of gasses (carbon dioxide, methane, etc.).4 This presents the analyst with considerable challenges when developing methods for the characterisation and analysis of crude oils.5 The non-contact, non-destructive, quantitative analysis of crude petroleum oils is a highly desirable objective for both research (e.g. study of microscopic HCFI) and industry (e.g. real-time assessment of oil production). Satisfying the needs of both macroscopic and microscopic applications is not straightforward, however, optical methods offer a convenient route to achieving these goals. Fluorescence spectroscopy is the best available optical technique, because it offers high sensitivity, good diagnostic potential, relatively simple instrumentation, and is perfectly suited to both microscopy and portable instrumentationPublication Fluorescence analysis of thermoresponsive polymers(Springer Verlag, 2015-12-18) Morris, Cheryl; Ryder, Alan G.; Science Foundation IrelandThe use of microscale thin polymer films is widespread in biomedical science and engineering, with applications in areas such as tissue engineering, drug delivery, microfluidic devices, bio-adhesion mediators, and bio-actuators. Much attention is devoted to the use of functional polymers that display stimuliresponsive behavior with the intention of providing "smart" coatings. One potential example is the use of thin thermoresponsive polymer films as drug eluting coatings on medical devices, where not only does the polymer function as a drug reservoir but it also acts as a biocompatibility modulator to improve device performance.Often these thin polymer coatings have to be applied to complex geometries, which can cause problems for in-situ analysis. Another important consideration is the fact that these films have large surface area to mass ratios and thus water uptake can be significant. This is serious because coating stability, device efficacy, and long-term storage are influenced by the physiochemical properties of the polymer which are modulated by water content. Thus, there is a need for a rapid, non-contact, non-destructive, analytical method capable of analyzing thermoresponsive polymers in solution, and in-situ of the solid-state on medical devices. Fluorescence spectroscopy based methods can deal with both sample types and provide additional benefits in terms of high sensitivity and low probe concentrations, which provide for minimal sample disruption. This article gives a brief overview of the application of various fluorescence methods for the physicochemical characterization of thermoresponsive polymers such as poly (N-isopropylacrylamide), PNIPAm.Publication Synthesis of benzoylated beta-D-glucosamine derivatives(CRC Press / Taylor and Francis Group, 2017-09-19) Di Salvo, Claudia; Fox, Karen A.; Murphy, Paul V.; Langhanki, Jens; Science Foundation Ireland; European Regional Development Fund[No abstract available]Publication Powering fuel cells through biocatalysis(Academic Press, 2007-11-27) Leech, Dónal; Pellissier, Marie; Barrière, Frédéric[No abstract available]
