Cet article présente les résultats d’une recherche concernant les conceptions d’élèves de cycle 1 sur les concepts de masse et de volume et sur le comportement d’objets après leur immersion dans l’eau. Les résultats obtenus montrent que

Time-resolved dielectric investigation of relaxation kinetics in metastable caffeine

Autor: Anne-Amandine Decroix, Laurent Carpentier, Marc Descamps

Publikováno v: Philosophical Magazine. 88:3925-3930

Using time-resolved dielectric relaxation spectroscopy, we have studied the kinetics of the first-order phase transformation of caffeine from its high temperature rotational solid form to the room temperature phase. The results indicate that the kine

Journal of Molecular Structure, Elsevier, 2014, 1078, pp.165-173

International audience; Using dielectric relaxation data we have characterized the molecular mobilities of caffeine both in phase I (stable and metastable) and in phase II. In phase I effects of sublimation and phase transformation kinetics were care

Low- and High-Frequency Raman Investigations on Caffeine: Polymorphism, Disorder and Phase Transformation

Autor: Patrick Derollez, Marc Descamps, Anne-Amandine Decroix, Laurent Paccou, Yannick Guinet, Alain Hédoux

Publikováno v: Journal of Physical Chemistry B
Journal of Physical Chemistry B, American Chemical Society, 2011, 115 (19), pp.5746-5753. ⟨10.1021/jp112074w⟩

International audience; Raman investigations are carried out both in crystalline forms of caffeine and during the isothermal transformation of the orientationally disordered form I into the stable form II at 363 K. The time dependence of the Raman sp
