    • A Logistic Approach for Kinetics of Isothermal Pyrolysis of Cellulose 

      López-Beceiro, Jorge; Díaz-Díaz, Ana-María; Álvarez García, Ana; Tarrío-Saavedra, Javier; Naya, Salvador; Artiaga, Ramón (MDPI, 2021-03)
      [Abstract] A kinetic model is proposed to fit isothermal thermogravimetric data obtained from cellulose in an inert atmosphere at different temperatures. The method used here to evaluate the model involves two steps: (1) ...

    • A relatively simple look at the rather complex crystallization kinetics of PLLA 

      López-Beceiro, Jorge; Díaz-Díaz, Ana-María; Fernández-Pérez, Enrique; Ferreira, Ignatius; Focke, Walter W.; Artiaga, Ramón (MDPI, 2023-04-14)
      [Abstract] This work demonstrates that, despite the existence of a significant number of works on PLA crystallization, there is still a relatively simple way, different from those already described, in which its complex ...

    • Application of the Time–Temperature Superposition Principle to Predict Long-Term Behaviour of an Adhesive for Use in Shipbuilding 

      Souto Silvar, Daniel Abelardo; Álvarez García, Ana; Díaz-Díaz, Ana-María; Rodríguez-Dopico, Francisco J.; López-Beceiro, Jorge (Springer Nature, 2024-02)
      [Abstract]: The use of adhesives in the marine sector is rather limited at the time being, but their use in specific areas of the ship would be an advantage due, among other things, to their low weight and low stress ...

    • Comparison by thermal analysis of Joule‑cured versus oven‑cured composites 

      Vázquez, Laura; López-Beceiro, Jorge; Díaz-Díaz, Ana-María; Álvarez García, Ana; Pereira Rodríguez, Mercedes; Artiaga, Ramón (Springer, 2024-03-20)
      [Abstract]: The current technology for curing high-performance composites, such as those used in industries like such as aeronautics and the automotive industry, is based on the use of autoclaves, where the material is ...

    • Crystallization kinetics of a commercial poly(lactic acid) based on characteristic crystallization time and optimal crystallization temperature 

      Díaz-Díaz, Ana-María; López-Beceiro, Jorge; Yanchun, Li; Cheng, Yi; Artiaga, Ramón (Springer, 2020-07-23)
      [Abstract]: A model is proposed to fit differential scanning calorimetry (DSC) isothermal crystallization curves obtained from the molten state at different temperatures. A commercial 3D printing polylactic acid (PLA) ...

    • Dynamic rheological comparison of silicones for podiatry applications 

      Díaz-Díaz, Ana-María; Sánchez Silva, Bárbara; Tarrío-Saavedra, Javier; López-Beceiro, Jorge; Janeiro Arocas, Julia M.; Gracia-Fernández, Carlos; Artiaga, Ramón (Elsevier, 2018-05-26)
      [Abstract]: This work shows an effective methodology to evaluate the dynamic viscoelastic behavior of silicones for application in podiatry. The aim is to characterize, compare their viscoelastic properties according to ...

    • Erosive Degradation Study of Concrete Augmented by Mussel Shells for Marine Construction 

      Camba, C.; Mier, José; Carral Couce, Luis; Lamas, M.I.; Álvarez-Feal, José-Carlos; Díaz-Díaz, Ana-María; Tarrío-Saavedra, Javier (MDPI, 2021-10)
      [Abstract] This work proposes a green material for artificial reefs to be placed in Galicia (northwest Spain) taking into account the principles of circular economy and sustainability of the ecosystem. New concrete ...

    • Filtro de Kalman lineal variable basado en cuaternas para unidad de medida inercial, con aplicación en dinámica de vehículos 

      Díaz-Díaz, Ana-María (2012)
      [Resumen] El seguimiento preciso en tiempo real de un sólido rígido tiene muchas aplicaciones en distintos ámbitos industriales; se podrían señalar entre ellos robótica, ingeniería aeroespacial, realidad virtual y otros. ...

    • Kinetics of Thermal Degradation of Cellulose: Analysis Based on Isothermal and Linear Heating Data 

      López-Beceiro, Jorge; Álvarez García, Ana; Sebio-Puñal, Sebio; Zaragoza, Sonia; Álvarez García, Begoña; Díaz-Díaz, Ana-María; Janeiro Arocas, Julia M.; Artiaga, Ramón (NC State University, 2016-05-16)
      [Abstarct]: In spite of the many studies performed, there is not yet a kinetic model to predict the thermal degradation of cellulose in isothermal and non-isothermal conditions for the full extent of conversion. A model ...

    • Properties of Mosquito Repellent-Plasticized Poly(lactic acid) Strands 

      Mapossa, Antonio B.; López-Beceiro, Jorge; Díaz-Díaz, Ana-María; Artiaga, Ramón; Moyo, Dennis; Mphateng, Thabang N.; Focke, Walter W. (MDPI, 2021-09)
      [Abstract] Poly(lactic acid) (PLA) is an attractive candidate for replacing petrochemical polymers because it is fully biodegradable. This study investigated the potential of PLA as a sustainable and environmentally friendly ...

    • The Complexity of Lignin Thermal Degradation in the Isothermal Context 

      López-Beceiro, Jorge; Díaz-Díaz, Ana-María; Álvarez García, Ana; Tarrío-Saavedra, Javier; Naya, Salvador; Artiaga, Ramón (MDPI, 2021-07)
      [Abstract] Thermal degradation of lignin in nitrogen atmosphere is evaluated by linear heating and isothermal tests. While linear heating suggests that thermal decomposition in the 200–400 °C range mainly consists of a ...

    • The effect of marine ageing on the mechanical properties of a structural adhesive
