Optimization by response surface methodology of the reaction conditions in 1,3-selective transesterification of sunflower oil, by using CaO as heterogeneous catalyst
(Elsevier, 2020)
In this work, the experimental conditions for the transesterification reaction of sunflower oil, over commercial calcium oxide (CaO) as heterogeneous catalysts, have been optimized employing a multi-factorial design based ...
Silver and Gold Nanoparticles for Antimicrobial Purposes against Multi-Drug Resistance Bacteria
(MDPI, 2022)
Several pieces of research have been done on transition metal nanoparticles and their nanocomplexes as research on their physical and chemical properties and their relationship to biological features are of great importance. ...
MIL-88A Metal-Organic Framework as a Stable Sulfur-Host Cathode for Long-Cycle Li-S Batteries
(MDPI, 2020)
Lithium-sulfur (Li-S) batteries have received enormous interest as a promising energy storage system to compete against limited, non-renewable, energy sources due to their high energy density, sustainability, and low cost. ...

(Universidad de Córdoba, UCOPress, 2022)
Introducción o motivación de la Tesis Doctoral. El estudio por las técnicas instrumentales que habitualmente se emplean en las ciencias químicas en materiales arqueológicos implica una interdisciplinariedad entre especialistas ...
Biodiesel Is Dead: Long Life to Advanced Biofuels—A Comprehensive Critical Review
(MDPI, 2022)
Many countries are immersed in several strategies to reduce the carbon dioxide (CO2) emissions of internal combustion engines. One option is the substitution of these engines by electric and/or hydrogen engines. However, ...
Synthesis of BiOI/Mordenite Composites for Photocatalytic Treatment of Organic Pollutants Present in Agro-Industrial Wastewater
(MDPI, 2022)
Recently, bismuth oxyiodide (BiOI) is an attractive semiconductor to use in heterogeneous photocatalysis processes. Unfortunately, BiOI individually shows limited photocatalytic efficiency, instability, and a quick ...
Biofuels from Diethyl Carbonate and Vegetable Oils for Use in Triple Blends with Diesel Fuel: Effect on Performance and Smoke Emissions of a Diesel Engine
(MDPI, 2020)
The main objective of this work is to contribute to a gradual replacement process of fossil diesel (D) with biofuels composed by diethyl carbonate (DEC) and either sunflower or castor oil, as straight vegetable oils (SVOs). ...
Glycerol and Catalysis by Waste/Low-Cost Materials—A Review
(MDPI, 2022)
The growing global demand for renewable energy sources can be reached using biofuels such as biodiesel, for example. The most used route to produce biodiesel is the transesterification reaction of oils or fats with short-chain ...
Identification of Catalytic Active Sites for Durable Proton Exchange Membrane Fuel Cell: Catalytic Degradation and Poisoning Perspectives
(Wiley, 2022)
Recent progress in synthetic strategies, analysis techniques, and computational modeling assist researchers to develop more active catalysts including metallic clusters to single-atom active sites (SACs). Metal coordinated ...
Experimental and Theoretical Advances on Single Atom and Atomic Cluster-Decorated Low-Dimensional Platforms towards Superior Electrocatalysts
(Wiley, 2022)
The fundamental relationship between structure and properties, which is called “structure-property”, plays a vital role in the rational designing of high-performance catalysts for diverse electrocatalytic applications. ...
