    Ultrasonic properties of materials present a strong dependence on temperature and in turn the ultrasonic velocity of propagation in the material under test. It is precisely for this reason that most ultrasonic measurements ...
  • Analisis y diseño de un oscilador en banda V 

    Corbella Sanahuja, Ignasi; Salazar Soler, Jorge (1991)
    Conference report
    Open Access
    In this paper the analysis and design of an oscillator in V band is presented. Taking advantage of a coaxial oscillation, sorne results related with frequency stability have been obtained. A special attention has been paid ...
  • Ultrasonic velocity of water-ethanol-malic acid-lactic acid mixtures during the malolactic fermentation process 

    Amer, M.A.; Novoa-Díaz, Daniel F.; Puig-Pujol, A.; Capdevila, Josefina; Chávez Domínguez, Juan Antonio; Turó Peroy, Antonio; García Hernández, Miguel J.; Salazar Soler, Jorge (Elsevier, 2015-03)
    Article

    During malolactic fermentation in wines, malic acid is transformed into lactic acid by the action of lactic acid bacteria. This process can be monitored on-line by measuring the velocity of a low intensity ultrasonic wave ...
  • Ultrasonic monitoring of malolactic fermentation in red wines 

    Novoa-Díaz, Daniel F.; Rodríguez Nogales, J. M.; Fernández Fernández, E.; Vila Crespo, J.; García Álvarez, Víctor Óscar; Amer, M.A.; Chávez Domínguez, Juan Antonio; Turó Peroy, Antonio; García Hernández, Miguel J.; Salazar Soler, Jorge (2014-08-01)
    Article
