    Study of the frequency factor in the thermal desorption of astrophysical ice analogs: CH4, C2H4, C2H6, CH3OH, CO, CO2, H2O and N2 
    Luna Molina, Ramón; Domingo Beltran, Manuel; Millán Verdú, Carlos; Santonja Moltó, Mª Del Carmen; Satorre, M. Á. (Elsevier, 2018)
    [EN] In this work the frequency factor and the influence of the temperature on this parameter, for zeroth order desorption processes, has been experimentally determined for eight molecules of astrophysical interest. In the ...

    The shape influence on the overall single scattering properties of a sample in random orientation 
    Vilaplana Cerda, Rosario Isabel; Luna Molina, Ramón; Guirado, D. (Elsevier, 2011)
    [EN] In order to identify the type of scattering profile that corresponds to some specific shapes, we have performed calculations of some scattering properties for those shapes with a fixed size distribution. Aggregates ...

    Thermal desorption of methanol in hot cores. Study with a quartz crystal microbalance 
    Luna Molina, Ramón; Satorre, M. Á.; Domingo Beltran, Manuel; Millán Verdú, Carlos; Luna-Ferrándiz, Ramón; Gisbert-Pérez, Georgina María; Santonja Moltó, Mª Del Carmen (Oxford University Press, 2018)
    [EN] The desorption process of methanol in the hot cores of massive young stars is addressed in this work. The study of pure methanol ice and when it is mixed or layered with water allows a better understanding of the ...

    Upgraded sublimation energy determination procedure for icy films 
    Luna Molina, Ramón; Millán Verdú, Carlos; Domingo Beltran, Manuel; Santonja Moltó, Mª del Carmen; Satorre Aznar, Miguel Ángel (Elsevier, 2012-06-20)
    A method to determine the sublimation energy of a bulk ice in high vacuum systems, allowing other simultaneous analysis techniques, is presented. Variation in frequency of a quartz crystal microbalance, due to sublimating ...
