  • Quartz crystal microbalance holder design for on-line sensing in liquid applications 

    Amer, M.A.; Chávez Domínguez, Juan Antonio; García Hernández, Miguel J.; Salazar Soler, Jorge; Turó Peroy, Antonio (2016-05)
    Article
    Accés obert
    In this paper, the design of a QCM sensor for liquid media measurements in vertical position is described. A rugged and low-cost proof holder has been designed, the cost of which is significantly lower than those ...
  • Temperature compensation of ultrasonic velocity during the malolactic fermentation process 

    Amer, Miquel Àngel; Novoa-Díaz, Daniel F.; Chávez Domínguez, Juan Antonio; Turó Peroy, Antonio; García Hernández, Miguel J.; Salazar Soler, Jorge (2015-11-04)
    Article
    Accés obert
    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 ...
  • 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
    Accés restringit per política de l'editorial
    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
    Accés restringit per política de l'editorial
    The progress of malolactic fermentation in red wines has been monitored by using ultrasonic techniques. The evolution of ultrasonic velocity of a tone burst 1 MHz longitudinal wave was measured, analyzed and compared to ...
  • Study of the effect of angle errors in conical ultrasonic sensors 

    García Álvarez, Víctor Óscar; García Hernández, Miguel J.; Chávez Domínguez, Juan Antonio; Turó Peroy, Antonio; Salazar Soler, Jorge (2013-09-01)
    Article
    Accés restringit per política de l'editorial
    Many ultrasonic sensors intended for non-destructive testing include a plastic or metal element, known as buffer rod, between the ultrasonic transducer and the material under analysis. Buffer rods are often terminated in ...
  • Resizing buffer rods for ultrasound testing of food products with acoustic noise considerations 

    García Álvarez, J.; García Hernández, Miguel J.; Novoa-Díaz, D.F.; Turó Peroy, Antonio; Chávez Domínguez, Juan Antonio; Salazar Soler, Jorge (2013-01)
    Article

    Buffer rods can be used to perform non-destructive and on-line analysis of food and beverage products. These rods, usually solid cylinders, can be long and heavy for certain applications. In this paper, a resizing analytic ...
  • Ultrasonic inspection system for powder metallurgy parts 

    Turó Peroy, Antonio; Chávez Domínguez, Juan Antonio; García Hernández, Miguel J.; Bulkai, András; Tomek, Péter; Tóth, Gabor; Gironés, Ana; Salazar Soler, Jorge (2013-04)
    Article
    Accés restringit per política de l'editorial
    The demand for powder metallurgy (P/M) parts in its traditional automotive market is predicted to grow, but future sector expansion depends directly upon its capability to manufacture zero-defect parts for industries such ...
