    • Biodegradability and biocompatibility of copoly(butylene sebacate-co-terephthalate)s 

      Heidarzadeh, Nina; Mehdi Rafizadeh, Mehdi; Faramarz Afshar Taromi, Faramarz Afshar; Valle Mendoza, Luis Javier del; Franco García, María Lourdes; Puiggalí Bellalta, Jordi (2017-01-01)
      Article
      Accés obert
      In the present study poly (butylene sebacate-co-terephthalate)s having different compositions were synthesized with a high yield and a random distribution by thermal transesterification of poly (butylene sebacate) and poly ...

    • Chemical vs thermal accelerated hydrolytic degradation of 3D-printed PLLA/PLCL bioresorbable stents: characterization and influence of sterilization 

      Chausse Calbet, Victor; Iglesias, Clàudia; Bou Petit, Elisabeth; Ginebra Molins, Maria Pau; Pegueroles Neyra, Marta (Elsevier, 2023-01-01)
      Article
      Accés obert
      Bioresorbable stents (BRS) are designed to provide initial sufficient mechanical support to prevent vessel recoil while being degraded until their complete resorption. Therefore, degradation rate of BRS plays a crucial ...

    • Effect of chitin nanocrystals on crystallization and properties of poly(lactic acid)-based nanocomposites 

      Singh, Shikha; Maspoch Rulduà, M. Lluïsa (Multidisciplinary Digital Publishing Institute (MDPI), 2020-03-01)
      Article
      Accés obert
      The crystalline phase of poly(lactic acid) (PLA) has crucial effects on its own properties and nanocomposites. In this study, the isothermal crystallization of PLA, triethyl citrate-plasticized PLA (PLA–TEC), and its ...

    • Hydrolytic and enzymatic degradation of biobased poly(4-hydroxybutyrate) films. Selective etching of spherulites 

      Keridou, Ina; Franco García, María Lourdes; Valle Mendoza, Luis Javier del; Martínez, Juan Carlos; Funk, Lutz; Turon Dols, Pau; Puiggalí Bellalta, Jordi (2021-01)
      Article
      Accés obert
      Hydrolytic degradation of poly(4-hydroxybutyrate) (P4HB) films has been studied considering media of different pH values (i.e., 3, 7 and 10) and temperatures (i.e., 37 and 55 °C). Enzymatic degradation has also been evaluated ...

    • Hydrolytic degradation of D-mannitol-based polyurethanes 

      Romero Azogil, Lucía; Benito Hernández, Elena; Martínez de Ilarduya Sáez de Asteasu, Domingo Antxon; García Martín, Maria de Gracia; Galbis Pérez, Juan Antonio (2018-07-01)
      Article
      Accés obert
      The capacity of redox D-mannitol-based polyurethanes to modulate the glutathione response under physiological conditions, as well as their effectiveness for sustained and site-specific drug release in the gastrointestinal ...

    • Microstructural changes during degradation of biobased poly(4-hydroxybutyrate) sutures 

      Keridou, Ina; Franco García, María Lourdes; Valle Mendoza, Luis Javier del; Funk, Lutz; Turon, Pau; Puiggalí Bellalta, Jordi (Multidisciplinary Digital Publishing Institute (MDPI), 2020-09-01)
      Article
      Accés obert
      Fibers of poly(4-hydroxybutyrate) (P4HB) have been submitted to both hydrolytic and enzymatic degradation media in order to generate samples with different types and degrees of chain breakage. Random chain hydrolysis is ...

    • Study on the hydrolytic degradation of the segmented GL-b-[GL-co-TMC-co-CL] -b-GL copolymer with application as monofilar surgical suture 

      Márquez Lobato, Yolanda; Franco García, María Lourdes; Turón Dols, Pau; Rodríguez Galán, Rafael Alfonso; Puiggalí Bellalta, Jordi (2013-12)
      Article
