Biomass Derivative Valorization Using Nano Core‐Shell Magnetic Materials Based on Keggin‐Heteropolyacids: Levulinic Acid Esterification Kinetic Study with N‐Butanol

open access: yesJournal of Nanomaterials, Volume 2019, Issue 1, 2019., 2019
Magnetic materials based on Keggin heteropolyacids immobilized on mesoporous silica‐coated magnetite particles with a core‐shell structure were synthesized. The activity of the catalyst was studied in the esterification reaction of levulinic acid with n‐butanol, and its kinetics was studied by the systematic variation of several reaction parameters ...

Analysis of Small‐Scale Fading Distributions in Vehicle‐to‐Vehicle Communications

open access: yesMobile Information Systems, Volume 2016, Issue 1, 2016., 2016
This work analyzes the characteristics of the small‐scale fading distribution in vehicle‐to‐vehicle (V2V) channels. The analysis is based on a narrowband channel measurements campaign at 5.9 GHz designed specifically for that purpose. The measurements were carried out in highway and urban environments around the city of Valencia, Spain.
