On the Recovery of PLP-Molar Mass Distribution at High Laser Frequencies: A Simulation Study
Hamzehlou, Shaghayegh; Aboudzadeh, Ali; Reyes, Yuri (MDPI, 2019-08)
Due to the inherent difficulties in determination of the degree of branching for polymers produced in pulsed laser polymerization (PLP) experiments, the behavior of the degree of branching and backbiting reaction in high ... -
On the Relationship between Mechanical Properties and Crystallisation of Chemically Post-Processed Additive Manufactured Polylactic Acid Pieces
Valerga, Ana Pilar; Fernández Vidal, Severo Raúl; Girot Mata, Franck Andrés; Gámez López, Antonio Juan (MDPI, 2020-04-18)
Nowadays, improvement of the surface finish of parts manufactured by fused deposition modelling is a well-studied topic. Chemical post-treatments have proven to be the best technique in terms of time consumption and ... -
On the reliability of Larramendi’s evidence
Urgell Lázaro, Blanca (Servicio Editorial de la Universidad del País Vasco/Euskal Herriko Unibertsitatearen Argitalpen Zerbitzua, 2016)
In this article, the analysis of the sources of Manuel de Larramendi’s (1690-1766) grammar and dictionary reveals the importance of his work and asserts that they are necessary tools to better understand the history of the ... -
On the Road to Sustainable Energy Storage Technologies: Synthesis of Anodes for Na-Ion Batteries from Biowaste

Hard carbon is one of the most promising anode materials for sodium-ion batteries. In this work, new types of biomass-derived hard carbons were obtained through pyrolysis of different kinds of agro-industrial biowaste ... -
On the role of social equity in payments for ecosystem services in Latin America: A practitioner perspective
(ECOLOGICAL ECONOMICS, 2021)One of the main debates surrounding payments for ecosystem services (PES) is to what extent should PES design focus on social equity concerns. While much of the debate is centered around theoretical arguments, here we focus ... -
On the role of sustainability in European fund pricing using morningstar ratings
(2022-12-14)This paper tests whether introducing the sustainable investment effect may be considered an additional variable for both Fama & French’s three-factor model and Carhart’s four-factor model so that the performance of asset ... -
