Paradigmatic case of long-term colocated wind–wave energy index trend in Canary Islands
(Elsevier, 2023-05)
Previous studies based on remote sensing data and reanalysis have identified strong historical increments of wind speed in the area around the Canary Islands (Spain) without appreciating any increment of wave height. This ...
Stability of a Rh/CeO2–ZrO2 Catalyst in the Oxidative Steam Reforming of Raw Bio-oil
(ACS, 2018-02-21)
The oxidative steam reforming (OSR) of raw bio-oil (obtained by fast pyrolysis of pine sawdust) has been studied on a Rh/CeO2-ZrO2 catalyst under a wide range of operating conditions (600-750 ºC; steam to carbon molar ratio ...
CFD modelling of the powder segregation in multi-material laser directed energy deposition
(Elsevier, 2024-04)
One of the prevailing challenges in multi-material laser Directed Energy Deposition is the segregation of the constituents during the delivery of the feedstock into the melt pool. This phenomenon is of particular concern ...
