Optimal Operation Strategies into Deregulated Markets for 50 MWe Parabolic Trough Solar Thermal Power Plants with Thermal Storage
(MDPI, 2019)
The evolution of electric generation systems, according to relevant legislation, allows for the parallel evolution of the installed power capacity of renewable resources with the development of technologies for renewable ...
A Memory-Efficient True-RMS Estimator in a Limited-Resources Hardware
(MDPI, 2019)
More and more human activities are increasingly dependent on the power quality energy they are supplied. In particular, those loads that have an electronic switching mode power supply (SMPS) and microcontrollers or ...
An IoT Based Mobile Augmented Reality Application for Energy Visualization in Buildings Environments
(MDPI, 2020)
Augmented reality (AR) improves how we acquire, understand, and display information without distracting us from the real world. These technologies can be used in different applications and industries as they can incorporate ...

Hydrogen Production through Glycerol Photoreforming on TiO2/Mesoporous Carbon: Influence of the Synthetic Method
(MDPI, 2020)
This article explores the effect of the synthetic method of titanium dioxide (TiO2)/C composites (physical mixture and the water-assisted/unassisted sol-gel method) on their photocatalytic activity for hydrogen production ...
Evaluation of Dimethyl Carbonate as Alternative Biofuel. Performance and Smoke Emissions of a Diesel Engine Fueled with Diesel/Dimethyl Carbonate/Straight Vegetable Oil Triple Blends
(MDPI, 2021)
Dimethyl carbonate (DMC) is an interesting blending component for diesel fuel (D) owing to the high oxygen content (53 wt.%) and the absence of C–C bonds in its structure. Moreover, DMC can be produced from CO2 and methanol, ...
Acetone Prospect as an Additive to Allow the Use of Castor and Sunflower Oils as Drop-In Biofuels in Diesel/Acetone/Vegetable Oil Triple Blends for Application in Diesel Engines
(MDPI, 2020)
The present paper investigates the feasibility of using acetone (ACE) in triple blends with fossil diesel (D) and straight vegetable oils (SVOs) as alternative fuel for diesel engines. In this respect, ACE is selected as ...
An Efficient and Recyclable Nanoparticle-Supported Cobalt Catalyst for Quinoxaline Synthesis
(MDPI, 2015)
The syntheses of quinoxalines derived from 1,2-diamine and 1,2-dicarbonyl compounds
under mild reaction conditions was carried out using a nanoparticle-supported cobalt catalyst.
The supported nanocatalyst exhibited ...
Continuous-Flow Hydrogenation of Methyl Levulinate Promoted by Zr-Based Mesoporous Materials
(MDPI, 2019)
Several Zr-based materials, including ZrO2 and Zr-SBA-15, with different silicon/zirconium molar ratios, and ZrO2/Si-SBA-15 (where SBA-15 stands for Santa Barbara Amorphous material no. 15), have been prepared as hydrogenation ...
Efficient Enzyme-Free Biomimetic Sensors for Natural Phenol Detection
(MDPI, 2016)
The development of sensors and biosensors based on copper enzymes and/or copper
oxides for phenol sensing is disclosed in this work. The electrochemical properties were studied
by cyclic and differential pulse voltammetry ...
