Kinetic modeling and reactor design of the direct synthesis of dimethyl ether for CO2 valorization. A review
(Elsevier, 2022-08-04)
The direct synthesis of dimethyl ether (DME) is considered one of the most attractive routes for valorizing CO2 and syngas on a large scale. DME has a high cetane number and its properties are similar to those of liquefied ...
Hybrid Modeling of Deformable Linear Objects for Their Cooperative Transportation by Teams of Quadrotors
(MDPI, 2022-05-23)
his paper deals with the control of a team of unmanned air vehicles (UAVs), specifically quadrotors, for which their mission is the transportation of a deformable linear object (DLO), i.e., a cable, hose or similar object ...
Experimental implementation of a catalytic membrane reactor for the direct synthesis of DME from H2+CO/CO2
(Elsevier, 2021-01-05)
The direct synthesis of dimethyl ether (DME) by the hydrogenation of CO2 and CO2/COx mixtures has been studied in an original packed bed membrane reactor (PBMR). The role of the hydrophilic LTA zeolite membrane is to remove ...
Identification and measurement of tropical tuna species in purse seiner catches using computer vision and deep learning
(Elsevier, 2022-03)
Fishery monitoring programs are essential for effective management of marine resources, as they provide scientists and managers with the necessary data for both the preparation of scientific advice and fisheries control ...
Improvement of boring operations by means of mode coupling effect
(Elsevier, 2022-05)
Boring bars are inherently slender tools which are prone to show chatter problems due to their low dynamic stiffness and damping, being this problem their main limitation in productivity. The onset of chatter is mainly ...
Strategies for the intensification of CO2 valorization in the one-step dimethyl ether synthesis process
(ACS, 2019-12-16)
The intensification of CO2 valorization has been theoretically studied in the direct synthesis of dimethyl ether (DME) carried out in a packed-bed reactor by means of two strategies pursuing the attenuation of the thermodynamic ...
Large impact of phonon lineshapes on the superconductivity of solid hydrogen
(Springer Nature, 2024-05-09)
Phonon anharmonicity plays a crucial role in determining the stability and vibrational properties of high-pressure hydrides. Furthermore, strong anharmonicity can render phonon quasiparticle picture obsolete questioning ...
What has changed over 18 years? Future teachers’ language use and attitudes towards multilingualism in the Basque Autonomous Community
(Taylor & Francis, 2022-09-19)
Attitudes are learned and one’s personal experience and social environment play a role in shaping them. Teachers in particular exert a significant impact on the formation of students’ language attitudes.
This study targets ...
Meta-analysis reveals that the effects of precipitation change on soil and litter fauna in forests depend on body size
(Global Change Biology, 2024-05-01)
Anthropogenic climate change is altering precipitation regimes at a global scale. While precipitation changes have been linked to changes in the abundance and diversity of soil and litter invertebrate fauna in forests, ...
On pre-emptive vehicle stability control
(Taylor & Francis, 2021-03-30)
[EN] Future vehicle localisation technologies enable major enhancements of vehicle dynamics control. This study proposes a novel vehicle stability control paradigm, based on pre-emptive control that considers the curvature ...
