    • Caracterización del equipo piloto de crioconcentración de película alimentado con bomba peristáltica y variador de velocidad: ensayos con azúcares básicos 

      Villena Perez, Irene (Universitat Politècnica de Catalunya, 2014-06-06)
      Bachelor thesis
      Open Access
      This study is about the characterization of the operation of a cryoconcentration laboratory scale device equipped with a peristaltic pump and a variable speed drive. The fluid behavior and its limitations are studied in ...
    • Domain growth in binary mixtures at low temperatures 

      Lacasta Palacio, Ana María; Hernández Machado, Aurora; Sancho, Jose Maria; Toral Garcés, Raúl (The American Physical Society, 1992-03-01)
      Article
      Open Access
      We have studied domain growth during spinodal decomposition at low temperatures. We have performed a numerical integration of the deterministic time-dependent Ginzburg-Landau equation with a variable, concentration-dependent ...
    • Efectes calòrics en l’estat sòlid induïts per camps hidrostàtics 

      Dalmases Ceamanos, Marc (Universitat Politècnica de Catalunya, 2014-09)
      Master thesis (pre-Bologna period)
      Open Access
      Aquest projecte s’emmarca en la fase d’investigació fonamental dels efectes calòrics resultants de l’aplicació d’un camp hidrostàtic. L’objectiu és valorar les mostres seleccionades com a possibles candidates per a futures ...
    • Effects of domain morphology in phase-separation dynamics at low temperature. 

      Lacasta Palacio, Ana María; Sancho, Jose Maria; Hernández Machado, Aurora; Toral, Raul. (American Physical Society, 1993-09-01)
      Article
      Open Access
      We present numerical results of the deterministic Ginzburg-Landau equation with a concentration-dependent diffusion coefficient, for different values of the volume fraction phi of the minority component. The morphology of ...
    • Freeze desalination by the integration of falling film and block freeze concentration techniques 

      Zambrano, A.; Ruiz Pardo, Ruth Yolanda; Hernández Yáñez, Eduard; Raventós Santamaria, Mercè; Moreno, F. L. (2018-06-15)
      Article
      Open Access
      Block and falling film freeze concentration are two technologies that separate water by freezing,with the potential to desalinate seawater. In this study, the integration of two freeze concentration techniques as an ...
    • Lunar ISRU Energy Storage and Electricity Generation 

      Fernández Palos, Mario; Serra, Pol; Fereres, Sonia; Stephenson, Keith; González Cinca, Ricardo (2020)
      Conference lecture
      Open Access
      The survival of the astronauts and their equipment is the priority for any long-term exploration mission to the Moon. The provision of energy during the long lunar nights is a critical part of these missions. Several ...
    • Microalgae conversion to biogas: Thermal pretreatment contribution on net energy production 

      Passos, Fabiana Lopes del Rei; Ferrer Martí, Ivet (2014-06-17)
      Article
      Restricted access - publisher's policy
      Microalgal biomass harvested from wastewater treatment high rate algal ponds may be valorised through anaerobic digestion producing biogas. However, microalgae anaerobic biodegradability is limited by their complex cell ...
    • Multiphysics modeling and experimental validation of low temperature accumulator for cryogenic space propulsion systems 

      Torras Ortiz, Santiago; Castro González, Jesús; Rigola Serrano, Joaquim; Morales Ruíz, Sergio; Riccius, Jorg; Leiner, Johannes (2019-01-01)
      Article
      Restricted access - publisher's policy
      Within the framework of Low Thrust Cryogenic Propulsion (LTCP) systems, a low-temperature accumulator acting as thermal energy storage tank is an interesting option for cyclical processes under intermittent firings avoiding ...
    • Summer heatwaves trends and hotspots in the Barcelona metropolitan region (1914–2020) 

      Serra de Larrocha, Carina; Lana Pons, Francisco Javier; Martínez Santafé, Maria Dolors; Arellano Ramos, Blanca; Roca Cladera, Josep; Biere Arenas, Rolando Mauricio (Springer, 2024-03-06)
      Article
      Open Access
      Daily maximum, TX, and minimum, TN, temperatures recorded at Fabra Observatory, for the period 1914–2020 (from June to September), have permitted to identify the daytime and night time heatwaves, HWs, at the Barcelona ...
    • Updated BVD modeling of AlN-based solidly mounted resonators working at cryogenic and high temperatures: from -160°C up to 130°C 

      Lugo Hernández, Eduardo; Collado Gómez, Juan Carlos; Mateu Mateu, Jordi; Carmona Cejas, José Manuel; Mirea, Teona; Olivares Roza, Jimena (Institute of Electrical and Electronics Engineers (IEEE), 2022)
      Conference lecture
      Open Access
      In this work we theoretically and experimentally assess the behavior of AlN-based Solidly Mounted Resonators (SMR) at cryogenic and high temperatures. This study can be useful for precise behavior prediction of SMR sensors ...
