Kinetic Model for the Direct Conversion of CO2/CO into Light Olefins over an In2O3–ZrO2/SAPO-34 Tandem Catalyst
(ACS, 2024-01)
An original kinetic model is proposed for the direct production of light olefins by hydrogenation of CO2/CO (COx) mixtures over an In2O3–ZrO2/SAPO-34 tandem catalyst, quantifying deactivation by coke. The reaction network ...
Enhancing polarization transfer from nitrogen-vacancy centers to external nuclear spins via dangling bond mediators
(Nature, 2024)
The use of nitrogen-vacancy (NV) centers in diamond as a non-invasive platform for hyperpolarizing nuclear spins in molecular samples is a promising area of research with the potential to enhance the sensitivity of nuclear ...
Self-assembly and crystallization of double crystalline aliphatic thermoplastic biopolyurethane and its nucleation with cellulose nanocrystals
(Elsevier, 2022-01-13)
[EN] An aliphatic segmented thermoplastic biopolyurethane (STPU), based on aliphatic hexamethylene diisocyanate (HDI) and 1,3 propanediol (1,3PD) as urethane rich phase and a poly(sebacate) as a macrodiol phase, with ~50 ...
Techno-economic and environmental analyses of a solar-assisted Stirling engine cogeneration system for different dwelling types in the United Kingdom
(Elsevier, 2024-02-06)
In this study, a hybrid cogeneration system that combines photovoltaic-thermal (PV-T) collectors with a Stirling engine, and a battery-pack-based energy option is proposed for residential applications. The system’s purpose ...
Zwitterionic stabilized water-borne polymer colloids for antifouling coatings
(Elsevier, 2024-03)
This study presents antifouling waterborne (meth)acrylic coatings prepared through seeded semi-continuous emulsion polymerization, using trace amounts of a zwitterionic monomer 2-(methacryloyloxy)ethyl dimethyl-(3-sulfop ...
Optimal design and operation of thermal energy storage systems in micro-cogeneration plants
(Elsevier, 2020-03-12)
The implementation of micro-cogeneration plants in residential buildings requires a technical and economic viability study. This analysis depends greatly on the regulatory framework controlling this kind of installations, ...
The ABC of Generalized Coordination Numbers and Their Use as a Descriptor in Electrocatalysis
(Wiley, 2023-07)
The quest for enhanced electrocatalysts can be boosted by descriptor-based analyses. Because adsorption energies are the most common descriptors, electrocatalyst design is largely based on brute-force routines that comb ...
Investigating the Extent to which Distributional Semantic Models Capture a Broad Range of Semantic Relations
(WILEY, 2023)
Distributional semantic models (DSMs) are a primary method for distilling semantic information from corpora. However, a key question remains: What types of semantic relations among words do DSMs detect? Prior work typically ...
The role of MYB28 and MYB29 in the tolerance of iron deficiency and the interplay between iron homeostasis and ammonium stress in Arabidopsis thaliana.
(2023-12-15)
El hierro y el nitrógeno son nutrientes cruciales para las plantas. El hierro está implicado en funciones vitales como la fotosíntesis y la síntesis de proteínas, pero a menudo es poco biodisponible en suelos con pH neutro ...
Development of a plant controller for grid-connected hybrid renewable power plants with enhanced market participation strategies
(2023-12-15)
Las plantas de generación híbridas que combinan fuentes de generación renovables con almacenamiento se presentan como una pieza clave en el proceso de descarbonización del sistema eléctrico. Esto se debe a las múltiples ...
