Hydrogen Photo-Production from Glycerol Using Nickel-Doped TiO2 Catalysts: Effect of Catalyst Pre-Treatment
(MDPI, 2019)
In the present piece of research, hydrogen production via the photo-reforming of glycerol (a byproduct from biodiesel generation) is studied. Catalysts consisted of titania modified by Ni (0.5% by weight) obtained through ...
Unprecedented Proline-Based Heterogeneous Organocatalyst for Selective Production of Vanillin
(MDPI, 2018)
An organocatalytic system based on an unprecedented proline analogue and iron oxide
magnetic nanoparticles (Prn/Fe2O3@SiO2) was designed and employed in vanillin production from
isoeugenol and vanillyl alcohol. Full ...
Stability and Activity of Zn/MCM-41 Materials in Toluene Alkylation: Microwave Irradiation vs Continuous Flow
(MDPI, 2019)
Zn/MCM-41 mesoporous materials have been prepared via classic wet impregnation, employing zinc nitrate as precursor and tested for activity and stability in the Friedel-Crafts alkylation of toluene with benzyl chloride ...
Microwave-Assisted Synthesis and Properties of Novel Hexaazatrinaphthylene Dendritic Scaffolds
(MDPI, 2020)
A novel family of water-soluble π-conjugated hexaazatrinaphthylenes-based dendritic architectures constructed by hexaketocyclohexane and 1,2,4,5-benzenetetramine units is developed in a microwave-assisted organic synthesis ...
Assessing Optimal Flight Parameters for Generating Accurate Multispectral Orthomosaicks by UAV to Support Site-Specific Crop Management
(MDPI, 2015)
This article describes the technical specifications and configuration of a multirotor unmanned aerial vehicle (UAV) to acquire remote images using a six-band multispectral sensor. Several flight missions were programmed ...
Mapping of Olive Trees Using Pansharpened QuickBird Images: An Evaluation of Pixel- and Object-Based Analyses
(MDPI, 2018)
This study sought to verify whether remote sensing offers the ability to efficiently delineate olive tree canopies using QuickBird (QB) satellite imagery. This paper compares four classification algorithms performed in ...
Drift Correction of Lightweight Microbolometer Thermal Sensors On-Board Unmanned Aerial Vehicles
(MDPI, 2018)
The development of lightweight sensors compatible with mini unmanned aerial vehicles
(UAVs) has expanded the agronomical applications of remote sensing. Of particular interest in this
paper are thermal sensors based on ...
An Analysis of the Influence of Flight Parameters in the Generation of Unmanned Aerial Vehicle (UAV) Orthomosaicks to Survey Archaeological Areas
(MDPI, 2016)
This article describes the configuration and technical specifications of a multi-rotor
unmanned aerial vehicle (UAV) using a red–green–blue (RGB) sensor for the acquisition of images
needed for the production of orthomosaics ...
SmartWinery: A Real-Time Monitoring System for Structural Health and Ullage in Fino StyleWine Casks
(MDPI, 2018)
The rapid development in low-cost sensor and wireless communication technology has
made it possible for a large number of devices to coexist and exchange information autonomously.
It has been predicted that a substantial ...
First Approach to a Holistic Tool for Assessing RES Investment Feasibility
(MDPI, 2018)
Combining availability, viability, sustainability, technical options, and environmental
impact in an energy-planning project is a difficult job itself for the today’s engineers. This becomes
harder if the potential ...
