ORBi Open Repository and Bibliography (319.770 recursos)

In may 2007, the ULg's Administrative Board (joined in June 2007 by the FUSAGx) decided to create an institutional repository and defined a strong institutional self-archiving policy to increase the visibility, accessibility and impact of the University's publications (Board's decision). This decision led to the official launch, in November 2008, of the ORBi platform including both the Academic Bibliography and the Institutional Repository of the Wallonia-Europe University Academy.

  3. Investigation of solid surface-enhanced Raman scattering (SERS) substrates for the quantification of dopamine in cell culture media

    Dumont, Elodie; De Bleye, Charlotte; Cailletaud, Johan; Deidda, Riccardo; Sacre, Pierre-Yves; Hubert, Philippe; Ziemons, Eric
    Since its discovery, surface-enhanced Raman spectroscopy (SERS) has constantly gained ground among the analytical techniques. One field of SERS that is rapidly expanding concerns the development of solid SERS substrates. These are made up of metallic nanomaterials set in a fixed configuration: either by complex and expensive techniques (lithography, printing) or by the immobilisation of suspensions of nanoparticles (NPs) previously synthesised. In bioanalysis, solid SERS substrates allow the performance of real-time monitoring of biological or cellular processes such as the release of neurotransmitters by stimulated cells or intercellular communications between cancer cells and the immune system. Dopamine (DA) is an...

  8. Effect of excitation wavelength and light exposure time on quantum dots luminescent properties

    Hottechamps, Julie; Noblet, Thomas; Humbert, Christophe; Dreesen, Laurent
    Optical biosensors constitute a major part of biosensors currently under development. Indeed, they generally show high specificity and sensitivity with a reduced size while remaining economical. Within this context, we combine the detection of the Förster resonance energy transfer (FRET) phenomenon, which is known for improving the sensitivity of sensors, and CdTe quantum dots (QDs), which are water-soluble and have specific optical properties to develop a sensing device. Although there are numerous examples of biosensors based on QDs and FRET, they are usually used without particular care concerning the wavelength and the power of the light source. In this work,...

  9. Feeding and ecological diversity of Tournaisian holocephalans: insights from dental microwear

    Demoulin, Catherine; Derycke, Claire; Michel, Christian; Fischer, Valentin
    At the end of the Devonian, several profound extinctions affected a large number of marine groups. However, some of them, such as holocephalan chondrichtyans, showed a great diversification during the recovery of the ecosystems, during the Tournaisian. Despite the fact that a large taxic diversity has been documented for these holocephalans; their ecological diversity is however poorly known, because the shape of isolated teeth can be a poor predictor of the ecology of these animals. Microwear analysis has the potential to reveal distinct diets and actual use of teeth in these extinct animals during the Tournaisian. We analysed the microwear of Tournaisian holocephalans from the Tournai and...
