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 ... -
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
Souto Silvar, Daniel Abelardo; Álvarez García, Ana; Díaz-Díaz, Ana-María; Rodríguez-Dopico, Francisco J.; López-Beceiro, Jorge (Springer, 2023)[Abstract] The aim of this work is to study the behaviour of a structural adhesive in an aggressive setting such as the marine environment. For this purpose, an ageing procedure is carried out under marine environmental ... -
Thermal and rheological comparison of adhesives
Sánchez Silva, Bárbara; Díaz-Díaz, Ana-María; Tarrío-Saavedra, Javier; López-Beceiro, Jorge; Gracia-Fernández, Carlos; Artiaga, Ramón (Springer, 2019-10-10)[Abstract]: In some industrial sectors such as naval construction, the use of adhesives is still limited to some specific applications. However, shipbuilders, academia and classification societies are cooperating to expand ...
