Experimental energy performance assessment of a solar desiccant cooling system in Southern Europe climates
(Elsevier, 2019)
Solar desiccant cooling systems, SDEC, could be an effective alternative to conventional cooling systems, which mainly depend on electrical energy. The main objective of this work was to determine experimentally the seasonal ...
Improving the electrocatalytic performance of sustainable Co/Carbon materials for oxygen evolution reaction by ultrasound and microwave assisted synthesis
(Royal Society of Chemistry, 2020)
The design of sustainable procedures for the preparation of cobalt/carbon-based materials as an anode for hydrogen fuel production through electrocatalytic water splitting has attracted much interest in the last few years. ...
Cr3+ substituted Zn-Al layered double hydroxides as UV–Vis light photocatalysts for NO gas removal from the urban environment
(Elsevier, 2019)
The ZnAl-CO3, ZnAlCr-CO3 and ZnCr-CO3 LDH samples were studied as De-NOx photocatalysts in this work. Samples without Cr and increasing the presence of Cr3+ in the LDH framework in the 0.06, 0.15 and 0.3 Cr/Zn ratio were ...
Effects of Fe3+ substitution on Zn-Al layered double hydroxides for enhanced NO photochemical abatement
(Elsevier, 2020)
In this work the ability of ZnAlFe-CO3 layered double hydroxides (LDHs) as highly efficient UV-Vis light photocatalysts for the photochemical oxidation of NO gas was studied. LDHs with 3.5 to 4.1 M2+/M3+ and 0.33 to 1.55 ...
Numerical and experimental analysis of the energy saving and potential of ventilation of opaque ventilates facades
(Universidad de Córdoba, Servicio de Publicaciones, 2013)
Nowadays the efficient use of energy is a crucial necessity. Buildings are among the
greater energy consumers in a country and the ventilation and HVAC systems account
for a high percentage of this consumption. A way of ...
Thermal and light irradiation effect on the electrocatalytic performance of Hemoglobin modified Co3O4-g-C3N4 nanomaterials for oxygen evolution reaction
(Royal Society of Chemistry, 2020)
The oxygen evolution reaction (OER) plays a key role in the water splitting process and a high energy conversion efficiency is essential for the definitive advance of hydrogen-based technologies. Unfortunately, the green ...
Universal Kinetic Model to Simulate Two-Step Biodiesel Production from Vegetable Oil
(MDPI, 2020)
To date, to simulate biodiesel production, kinetic models from different authors have been provided, each one usually applied to the use of a specific vegetable oil and experimental conditions. Models, which may include ...
Influence of Short Carbon-Chain Alcohol (Ethanol and 1-Propanol)/Diesel Fuel Blends over Diesel Engine Emissions
(MDPI, 2021)
Oxygenated fuels, in this case short carbon-chain alcohols, have been investigated as alternative fuels to power compression ignition engines. A major advantage of short-chain alcohols is that they can be produced from ...
Optimization of the Transesterification of Waste Cooking Oil with Mg-Al Hydrotalcite Using Response Surface Methodology
(MDPI, 2018)
Nowadays, biodiesel has become a very promising alternative to fossil diesel fuel, regarding
environmental concerns and fuel resource depletion. Biodiesel is usually produced through
homogeneous or heterogeneous ...
Mechanochemically Synthetized PAN-Based Co-N-Doped Carbon Materials as Electrocatalyst for Oxygen Evolution Reaction
(MDPI, 2021)
We report a new class of polyacrylonitrile (PAN)-based Co-N-doped carbon materials that can act as suitable catalyst for oxygen evolution reactions (OER). Different Co loadings were mechanochemically added into post-consumed ...
