Cation Effect in the Corrosion Inhibition Properties of Coumarate Ionic Liquids and Acrylic UV-Coatings
(MDPI, 2020-11-06)Chromate free corrosion inhibitors are searched for to mitigate the economic loss caused by mid-steel corrosion. Here, we show metal-free organic inhibitors having free coumarate anions that can be used either as direct ... -
Cells, Materials, and Fabrication Processes for Cardiac Tissue Engineering
(Frontiers Media, 2020-08-11)Cardiovascular disease is the number one killer worldwide, with myocardial infarction (MI) responsible for approximately 1 in 6 deaths. The lack of endogenous regenerative capacity, added to the deleterious remodelling ... -
CeO2 and La2O3 promoters in the steam reforming of polyolefinic waste plastic pyrolysis volatiles on Ni-based catalysts
(American Chemical Society, 2020-11-09)[EN] Based on the promising results of La2O3 and CeO2 promoted Ni/Al2O3 catalysts in the reforming of biomass pyrolysis volatiles, the performance of these catalysts and the non-promoted one was 2 evaluated in the pyrolysis ... -
CFD modeling and experimental validation of biomass fast pyrolysis in a conical spouted bed reactor
(Elsevier, 2020-12-31)[EN] A 2D Euler-Euler multiphase computational fluid dynamics (CFD) model in conjunction with the kinetic theory of granular flow (KTGF) was applied to describe the biomass pyrolysis in a spouted bed reactor. The primary ... -
Challenges and directions toward a general theory of ecological recovery dynamics: A metacommunity perspective
(One Earth, 2021-08-20)Global change degrades ecosystems worldwide. Scientific research has advanced our knowledge of the impacts of global change on ecosystems. Comparatively, however, it remains unclear how ecosystems recover after disturbances. ... -
Challenges for Digitalisation in Building Renovation to Enhance the Efficiency of the Process: A Spanish Case Study
(MDPI, 2021-11-03)Although construction is one of the largest industries in the world, it is one of the least digitised and its productivity is still very low. Excesses of time and cost are common and are even more accentuated for building ... -
Changes in institutional and social–ecological system robustness due to the adoption of large-scale irrigation technology in Navarre (Spain)
(Environmental Policy and Governance, 2020-07-01)Many regional and national organisations promote the modernisation of agriculture by supporting new technologies to increase their territory's competitiveness in a free-market context. Such technologies and their associated ... -
Characterisation of Exposure to Non-Ionising Electromagnetic Fields in the Spanish INMA Birth Cohort: Study Protocol
(Biomed Central, 2016-02-18)Background: Analysis of the association between exposure to electromagnetic fields of non-ionising radiation (EMF-NIR) and health in children and adolescents is hindered by the limited availability of data, mainly due to ... -
