Saline slag waste as an aluminum source for the synthesis of Zn–Al–Fe–Ti layered double-hydroxides as catalysts for the photodegradation of emerging contaminants
(Elsevier, 2020)
info:eu-repo/semantics/article,
In this work, aluminum extracted from saline slag waste is valorized to create a layered double-hydroxide series containing zinc and various proportions of aluminum/titanium. Materials were synthesized by the co-precipitation ...
Evaluación de una propuesta de aprendizaje basado en juegos de rol llevada a cabo en la asignatura de Cultura Cientíica de Bachillerato
(Facultad de Educación de la Universidad Católica de la Santísima Concepción (Chile), 2020)
info:eu-repo/semantics/article,
Debido a la falta de motivación e interés de los estudiantes por las ciencias y el bajo rendimiento académico español, la mayoría de las instituciones educativas utilizan metodologías activas, motivadoras y desaiantes para ...
Incorporating climate effects in Larix gmelinii improves stem taper models in the Greater Khingan Mountains of Inner Mongolia, northeast China
(Elsevier, 2020)
Artículo / Artikulua,
Estimating timber volume and carbon stock in forests is fundamental for silviculture and for accurate estimation of national and global carbon budgets. Taper models are important tools for predicting diameter at any height ...
Modelling forest ecosystems: a crossroad between scales, techniques and applications
(Elsevier, 2020)
Artículo / Artikulua,
When organizing this special issue, we (the guest editors) decided to carry out a quick overview of current
trends in forest modelling. To do so, we used Clarivate’s Web of Science to carry out a search in the top ...
Biodiesel synthesis using a novel monolithic catalyst with magnetic properties (K2CO3/γ-Al2O3/Sepiolite/γ-Fe2O3) by ethanolic route
(Elsevier, 2020)
info:eu-repo/semantics/article,
A novel magnetic monolithic catalyst based on K2CO3/γ-Al2O3/Sepiolite/γ-Fe2O3 was developed seeking to convert efficiently soybean oil and bioethanol to ethanolic biodiesel and glycerol. The magnetic monolithic was attained ...
Fe-C nanoparticles obtained from thermal decomposition employing sugars as reducing agents
(Elsevier, 2020)
info:eu-repo/semantics/article,
The aim of the work is to present a comparative analysis (structural and magnetic) of Fe-C nanocomposites obtained by the thermal decomposition of sugars (fructose, glucose and sucrose) employing FeCl3 as Fe3+ precursor. ...
Optimizing the removal of nitrate by adsorption onto activated carbon using response surface methodology based on the central composite design
(Taylor & Francis, 2020)
info:eu-repo/semantics/article,
This study sheds light on the adsorption process for the removal of nitrate ions from synthetic aqueous solutions. This contaminant pose a potential risk to the environment and can cause health effects including cancers ...
Effect of Cu substitution on the magnetic and magnetic induction heating response of CdFe₂O₄ spinel ferrite
(Elsevier, 2020)
info:eu-repo/semantics/article,
In this work, a comparative study of the effect of Cu on the structural, magnetic and magnetic induction heating response in CdFe2O4 spinel is presented. The ceramic nanoparticles (Cu1−xCdxFe2O4; 0 ≤ x ≤ 1) were synthesized ...
Progress and perspectives on pillared clays applied in energetic and environmental remediation processes
(Elsevier, 2020)
info:eu-repo/semantics/article,
Pillared interlayered clays (PILCs) are materials that show a two-dimensional layered porous structure with properties that could be interesting alternatives to zeolites and other microporous solids. Some of the properties ...
Zn-Ti-Al layered double hydroxides synthesized from aluminum saline slag wastes as efficient drug adsorbents
(Elsevier, 2020)
info:eu-repo/semantics/article,
This work reports the synthesis of Zinc-Titanium-Aluminum (ZnTiAl) layered double hydroxides (LDH) with various proportions of Al[sbnd]Ti and a Zn/(Al[sbnd]Ti) molar ratio of 3:1 by the co-precipitation method. Two series, ...
