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 ...

Geographical ecology of dry forest tree communities in the West Indies

open access: yesJournal of Biogeography, Volume 45, Issue 5, Page 1168-1181, May 2018., 2018
Abstract Aim Seasonally dry tropical forest (SDTF) of the Caribbean Islands (primarily West Indies) is floristically distinct from Neotropical SDTF in Central and South America. We evaluate whether tree species composition was associated with climatic gradients or geographical distance.

Small‐Scale Fading Analysis of the Vehicular‐to‐Vehicular Channel inside Tunnels

open access: yesWireless Communications and Mobile Computing, Volume 2017, Issue 1, 2017., 2017
We present a small‐scale fading analysis of the vehicular‐to‐vehicular (V2V) propagation channel at 5.9 GHz when both the transmitter (Tx) and the receiver (Rx) vehicles are inside a tunnel and are driving in the same direction. This analysis is based on channel measurements carried out at different tunnels under real road traffic conditions.
