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 ... -
Fast Visible-Light Photopolymerization in the Presence of Multiwalled Carbon Nanotubes: Toward 3D Printing Conducting Nanocomposites
(American Chemical Society, 2022-02)[EN] A new photoinitiator system (PIS) based on riboflavin (Rf), triethanolamine, and multiwalled carbon nanobutes (MWCNTs) is presented for visible-light-induced photopolymerization of acrylic monomers. Using this PIS, ... -
Fe/Olivine As Primary Catalyst in the Biomass Steam Gasification in a Fountain Confined Spouted Bed Reactor
(Elsevier, 2021-07-25)The performance of Fe/olivine catalysts was tested in the continuous steam gasification of sawdust in a bench scale plant provided with a fountain confined conical spouted bed reactor at 850 degrees C. Olivine was used as ... -
Financing climate and sustainability policies: The impact of sustainability bonds on the Basque country
(Ekonomiaz, 2020-01-01)Climate finance refers to the flow of financial resources for the fight against climate change and contribute to the achievement of the Sustainable Development Goals (SDG). The debt market can play an essential role through ... -
First determination of the spin and parity of the charmed-strange baryon Xi(c) (2970)(+)
(American Physical Society, 2021-06-16)We report results from a study of the spin and parity of Xi(c)(2970)(+) using a 980 fb(-1) data sample collected by the Belle detector at the KEKB asymmetric-energy e(+) e(-) collider. The decay angle distributions in the ... -
First measurement of the Lambda(+)(c) -> p eta ' decay
(Springer, 2022)[EN] We present the first measurement of the branching fraction of the singly Cabibbo-suppressed (SCS) decay Lambda(+)(c) -> p eta' with eta' -> eta pi(+)pi(-), using a data sample cor- responding to an integrated luminosity ... -

Flame Retardant Polyphosphoester Copolymers as Solid Polymer Electrolyte for Lithium Batteries
(RSC, 2021-05-19)Solid-state lithium batteries are considered one of the most promising battery systems due to their high volumetric energy density and safety. Poly(ethylene oxide) (PEO) is the most commonly used solid polymer electrolyte ... -
Flat-shaped carbon-graphene microcomposites as electrodes for high energy supercapacitors
(Royal Society of Chemistry, 2019-06-28)Herein, we report a simple approach for the preparation of phosphate-functionalized carbonaceous graphene-based composites. The homogeneous deposition of a thin layer of phenolic resin on the surface of graphene oxide (GO) ... -
Flexible aromatic disulfide monomers for high-performance self-healable linear and cross-linked poly(urethane-urea) coatings
(Elsevier, 2019)Implementation of the self-healing concept in coatings is challenging because they have to combine mechanical strength and chain mobility. This challenge is addressed in this work by studying the effect of the polymer ... -
Flexible Biocomposites with Enhanced Interfacial Compatibility Based on Keratin Fibers and Sulfur-Containing Poly(urea-urethane)s
(MDPI, 2018-09-21)Feathers are made of keratin, a fibrous protein with high content of disulfide-crosslinks and hydrogen-bonds. Feathers have been mainly used as reinforcing fiber in the preparation of biocomposites with a wide variety ... -
Flicker of Modern Lighting Technologies Due to Rapid Voltage Changes
(MDPI, 2019-03-01)The purpose of the present paper is to evaluate the sensitivity of modern lighting technologies to different types of RVCs. In order to do that, 27 modern lampsmainly LEDhave been subjected to real RVCs and their response ... -
Flight delays in Germany: a model for evaluation of future cost risk
(European Journal of Transport and Infrastructure Research, 2022-01-01)Air traffic has been increasing in Germany over the last decades reaching in 2018 an all-time high with more than 3 million flights. This increase has led to a rise in delays, which generate different costs to airlines, ... -
Floating matter: a neglected component of the ecological integrity of rivers
(Springer, 2019)Floating matter (FM) is a pivotal, albeit neglected, element along river corridors contributing to their ecological integrity. FM consists of particulate matter of natural (e.g. wood, branches, leaves, seeds) and anthropogenic ... -
