Excited-state band structure mapping
(American Physical Society, 2022-02-15)[EN] Angle-resolved photoelectron spectroscopy is an extremely powerful probe of materials to access the occupied electronic structure with energy and momentum resolution. However, it remains blind to those dynamic states ... -
Excitonic insulator to superconductor phase transition in ultra-compressed helium
(Springer Nature, 2023-07-25)Helium, the second most abundant element in the universe, exhibits an extremely large electronic band gap of about 20 eV at ambient pressures. While the metallization pressure of helium has been accurately determined, thus ... -
Exclusive Substitutional Nitrogen Doping on Graphene Decoupled from an Insulating Substrate
(American Chemical Society, 2020-10-08)The on-surface synthesis of atomically flat N-doped graphene on oxidized copper is presented. Besides circumventing the almost standard use of metallic substrates for growth, this method allows producing graphene with ... -
Experimental and Data Fitting Guidelines for the Determination of Polymer Crystallization Kinetics
(Springer Nature, 2022-05-05)The crystallization kinetics of semicrystalline polymers is often studied with isothermal experiments and analyzed by fitting the data with analytical expressions of the Avrami and Lauritzen and Hoffman (LH) theories. To ... -
Experimental Devices to Investigate the Long-Term Stability of Phase Change Materials under Application Conditions
(MDPI, 2020-11-10)An important prerequisite to select a reliable phase change material (PCM) for thermal energy storage applications is to test it under application conditions. In the case of solid–liquid PCM, a large amount of thermal ... -
Experimental evaluation of cement mortars with recycled brass fibres from the electrical discharge machining process
(Elsevier, 2020-06-20)This paper aims to evaluate the effect of recycled brass fibres on the physical, thermal and mechanical properties of cementitious mortars. For that purpose, seven different mortars, with the same water/cement ratio but ... -
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 ... -
Experimental implementation of precisely tailored light-matter interaction via inverse engineering
(Springer Nature Limited, 2021-09-14)Accurate and efficient quantum control in the presence of constraints and decoherence is a requirement and a challenge in quantum information processing. Shortcuts to adiabaticity, originally proposed to speed up the slow ... -
Experimental Semi-Autonomous Eigensolver Using Reinforcement Learning
(Nature, 2021-06-10)The characterization of observables, expressed via Hermitian operators, is a crucial task in quantum mechanics. For this reason, an eigensolver is a fundamental algorithm for any quantum technology. In this work, we implement ... -
Experimental study and modeling of biomass char gasification kinetics in a novel thermogravimetric flow reactor
(Elsevier B.V., 2020-04-25)[EN]This work pursues the validation of a new reactor for the evaluation of char gasification kinetics. This novel reactor allows continuous gas flow through the fixed bed sample and accurately monitoring the mass loss ... -
Experimental validation of a mathematical model for the evolution of the particle morphology of waterborne polymer-polymer hybrids: paving the way to the design and implementation of optimal polymerization strategies
(Elsevier, 2019-01-23)Polymer-polymer composite nanoparticles allow both the improvement of the performance in stablished applications of waterborne polymer dispersions and targeting new applications that are out of reach of currently available ... -
Exploring low-carbon futures: A web service approach to linking diverse climate-energy-economy models
(MDPI, 2019)The use of simulation models is essential when exploring transitions to low-carbon futures and climate change mitigation and adaptation policies. There are many models developed to understand socio-environmental processes ... -
Exposure to green areas: Modelling health benefits in a context of study heterogeneity
(Elsevier, 2020)Although the beneficial health effects of green areas are gaining recognition, epidemiological studies show mixed results with significance varying considerably by study and context, indicating that there is no unique and ... -
Exposure to metals and metalloids among pregnant women from Spain: Levels and associated factors
(Elsevier, 2022-01)[EN] Background: Humans are regularly exposed to metals and metalloids present in air, water, food, soil and domestic materials. Most of them can cross the placental barrier and cause adverse impacts on the developing ... -
Factors affecting energy-efficiency investment in the hotel industry: survey results from Spain
(Energy Efficiency, 2021)Increasing energy efficiency is a major way of saving energy and thus reducing energy expenses. However, adoption of energy efficiency is generally low, as demonstrated by the energy efficiency gap. To understand that gap, ... -
Factors associated with successful dietary changes in an energy-reduced Mediterranean diet intervention: a longitudinal analysis in the PREDIMED-Plus trial
(Springer, 2022)[EN] Purpose Long-term nutrition trials may fail to respond to their original hypotheses if participants do not comply with the intended dietary intervention. We aimed to identify baseline factors associated with successful ... -
Fast successive self-nucleation and annealing (SSA) thermal fractionation protocol for the characterization of polyolefin blends from mechanical recycling
(Wiley, 2022-04-29)The sorting stage of mechanical recycling of post-consumer polyolefins has severe challenges. Polypropylene (PP) is often contaminated with polyethylene (PE) and vice versa. To meet quality requirements, characterization ... -
