    Morphology Controlled Synthesis of α-GaO(OH) Nanoparticles: Thermal Conversion to Ga2O3 and Photocatalytic Properties by Ayse Dulda

    Published 2016-01-01
    “…XRD and TG analysis confirmed that there was a phase transition from GaO(OH) to Ga2O3 when precursor sample was calcined to 750°C. The single phase α-Ga2O3 was obtained after thermal treatment of NaOH precipitated precursor, while β-Ga2O3 was formed when the urea or NH4OH precipitated precursor was calcinated. …”

    Un autre football ? Catholiques et communistes italiens au tournant des années 1970 by Fabien Archambault

    Published 2013-01-01
    “…Les structures d’encadrement traditionnelles, qu’elles soient catholiques ou communistes, s’adaptent à cette nouvelle demande : une nouvelle pédagogie, fondée sur le dialogue et refusant l’autoritarisme, semble nécessaire ; la participation à des championnats, voire l’existence de ces derniers, est remise en cause ; le modèle du professionnalisme, perçu comme facteur d’aliénation, doit être combattu sans relâche. Ces positions novatrices sont partagées tant par des militants-entraîneurs communistes de l’Union italienne du sport populaire (UISP) que par certains laïcs de l’Action catholique mobilisés au sein du Centre sportif italien (CSI). …”
