    • Non-isothermal crystallization kinetics of poly(4-hydroxybutyrate) biopolymer 

      Keridou, Ina; Valle Mendoza, Luis Javier del; Funk, Lutz; Turon, Pau; Franco García, María Lourdes; Puiggalí Bellalta, Jordi (2019-08-05)
      Article
      Open Access
      The non-isothermal crystallization of the biodegradable poly(4-hydroxybutyrate) (P4HB) has been studied by means of differential scanning calorimetry (DSC) and polarizing optical microscopy (POM). In the first case, Avrami, ...
    • Numerical simulation of the alba synchrotron light source cooling system response for failure prevention 

      Escaler Puigoriol, Francesc Xavier; Casas, Joan; Colldelram, Carles; Quispe, Marcos; Prieto Moline, María Montserrat (2016)
      Conference lecture
      Open Access
      The ALBA Synchrotron Light Source cooling system is designed with a common return pipe that interconnects the four consumption rings. Such configuration is believed to compromise its optimal operation. To understand its ...
    • Numerical simulation of the alba synchrotron light source cooling system response to pump start-up and shut-down 

      Escaler Puigoriol, Francesc Xavier; Casas, Joan; Colldelram, Cales; Quispe, Marcos; Prieto Moline, María Montserrat (2016)
      Conference lecture
      Open Access
      The ALBA Synchrotron Light Source cooling system is submitted to regular pump start-ups and shut-downs. Moreover, pumps can trip due to motor power failures. As a result, the piping system can be subjected to surges and ...
    • Residual stress distribution of a 6061-T6 aluminum alloy under shear deformation 

      Reyes Ruiz, Carlos; Figueroa, I. A.; Braham, C.; Cabrera Marrero, José M.; Zanellato, O.; Baiz, S.; González de Rivera, G. (2016-07-18)
      Article
      Open Access
      There is a lack of information with regards to the friction effect in ECAPed aluminum alloys, even though it might substantially modify the deformation at the surface. In this work, the friction effect at the surface and ...
    • Sistema mecànic de posicionament dels miralls de transport de la línia del Sincrotró 

      Roura Garcia, Xavier (Universitat Politècnica de Catalunya, 2015-10-23)
      Bachelor thesis
      Open Access
      Covenantee:   Sincrotró ALBA
      Actualment la tècnica MIRAS (Microespectroscòpia Infraroja amb Radiació Sincrotró) és una de les més utilitzades en els àmbits de biologia i biomedicina, anàlisi forense i industrial, arqueometria i patrimoni cultural, en ...
    • SR-XRD and SR-FTIR study of the alteration of silver foils in medieval paintings 

      Salvadó Cabré, Nativitat; Buti Papiol, Salvador; Labrador, A.; Cinque, Gianfelice; Emerich, Hermann; Pradell Cara, Trinitat (2011)
      Article
      Restricted access - publisher's policy
      Altarpieces and polychrome carved wood from the fifteenth century AD usually exhibit golden and silvery areas by the application of a very thin foil of metal. The metal foils were normally protected from the atmosphere ...
    • Synchrotron radiation studies on even-odd and odd-even nylons 

      Franco García, María Lourdes; Puiggalí Bellalta, Jordi; Ricart López, Albert; Morales Gámez, Laura Teresa; Soto, David (IOP PUBLISHING LTD., 2009-09-08)
      Article
      Open Access
      Aliphatic polyamides derived from odd diamine or odd dicarboxylic acid units cannot adopt a conventional sheet structure when molecular chains have an all trans conformation. However, typical fiber diffraction patterns of ...
    • Thermo-fluid numerical simulation of the crotch absorbers’ cooling pinholes for alba storage ring 

      Escaler Puigoriol, Francesc Xavier; Arbó, Victor; Casas, Joan; Colldelram, Carles; Quispe, Marcos; Prieto Moline, María Montserrat (2016)
      Conference lecture
      Open Access
      The ALBA Synchrotron Light Facility crotch absorbers, that remove the unused storage ring radiation, incorporate an internal cooling system composed by a number of parallel pinholes and by the corresponding stainless steel ...
