From fundamental materials chemistry to sensing applications: unravelling the water adsorption mechanism of a luminescent optical fibre sensor membrane
This work provides insight into the correlation between the luminescent response of a water-vapour optical fibre sensor and the textural properties of its lanthanide-doped silica coating. To this end, a library of 16 silica ... -
On the characterization of lithium-ion batteries under overtemperature and overcharge conditions: identification of abuse areas and experimental validation
Although lithium-ion batteries have gained considerable popularity in renewable energy and electric vehicle applications, their safety still remains a concern under certain voltage, temperature, or state of charge conditions. ... -
Photoisomerization-induced LMR shift for UV radiation detection
(Elsevier, 2024) Artículo / ArtikuluaThis work presents an optical sensor for ultraviolet radiation (UV) detection, based on the combined effects of Lossy Mode Resonance (LMR) in the mid infrared (MIR) spectral region and the photoisomerization of a polymeric ... -
Conflicto normativo entre dos conceptos de biomasa: la condición jurídica de biomasa de unos residuos de celulosa en la legislación de emisiones industriales
Este estudio tiene su origen en un dictamen solicitado por una empresa con el objeto de determinar la condición jurídica de biomasa de los residuos de celulosa producidos en sus instalaciones industriales a efectos de la ... -

In this response letter, we would like to clarify some aspects related to the methodology and inferences derived from our work entitled 'Effects of Vivifrail multicomponent intervention on functional capacity', which was ... -
A biological insight of hops wastes vermicomposting by Eisenia Andrei
The study was conducted to assess the feasibility of using Eisenia andrei earthworms for vermicomposting hop remains from a lupulin extraction enterprises for the brewing industry. Vermicomposting process was conducted ... -
Ultraviolet erythemal irradiance (UVER) under different sky conditions in Burgos, Spain: multilinear regression and artificial neural network models
Different strategies for modeling Global Horizontal UltraViolet Erythemal irradiance (GHUVE) based on meteorological parameters measured in Burgos (Spain) have been developed. The experimental campaign ran from September ... -
Generation of lossy mode resonances (LMR) using perovskite nanofilms
The results presented here show for the first time the experimental demonstration of the fabrication of lossy mode resonance (LMR) devices based on perovskite coatings deposited on planar waveguides. Perovskite thin films ... -
A GIS-based methodology for assigning experimental measurements of angular distribution of sky radiance and luminance to selected sky sectors
Mathematical models for the estimation of the angular distribution of diffuse radiance/luminance in the sky describe the anisotropic character of diffuse solar radiation and daylight in the sky vault. In most of these ... -
Enhanced single-stage folded cascode OTA suitable for large capacitive loads
An enhanced single-stage folded cascode operational transconductance amplifier able to drive large capacitive loads is presented. Circuits that adaptively bias the input differential pair and the current folding stage ... -
3-D printed horn antennas and components performance for space and telecommunications
In this work, a study of the performance of several antennas and components, manufactured using an accurate stereolithography 3D printer and resin for maximum accuracy and detail, is carried out. Electroless plating of ... -
Moisture content estimation models of flour matrices in the 67-110 GHz frequency range using a nondestructive and contactless monitoring system
This work addresses the lack of moisture content estimation models for food products in the millimeter-wave frequency range and showcases the potential of this range for designing compact, cost-effective, and in-line food ... -
Two-wavelength phase-sensitive OTDR sensor using perfect periodic correlation codes for measurement range enhancement, noise reduction and fading compensation
We demonstrate a two-wavelength differential-phase-measuring OTDR sensor that uses perfect periodic correlation phase codes to enhance the measurement performance. The two-wavelength technique extends the measurement range ... -
Un modelo para predecir cuántas camas UCI harán falta durante cada oleada
La crisis financiera mundial de 2008 puso de moda en España el término económico “prima de riesgo”, hasta entonces desconocido. Del mismo modo, la pandemia ha popularizado expresiones y términos como “doblar la curva”, ... -
Acoustic lock: position and orientation trapping of non-spherical sub-wavelength particles in mid-air using a single-axis acoustic levitator
We demonstrate acoustic trapping in both position and orientation of a non-spherical particle of sub-wavelength size in mid-air. To do so, we multiplex in time a pseudo-one-dimensional vertical standing wave and a ... -
LeviPrint: contactless fabrication using full acoustic trapping of elongated parts
LeviPrint is a system for assembling objects in a contactless manner using acoustic levitation. We explore a set of optimum acoustic fields that enables full trapping in position and orientation of elongated objects such ... -
A GRASP-based algorithm for solving the emergency room physician scheduling problem
This paper addresses a physician scheduling problem in an Emergency Room (ER) requiring a long-term work calendar to allocate work days and types of shift among all the doctors. The mathematical model is created without ... -
Advanced phase-change intermediate heat exchanger development for multistage thermoelectric heat pumps
The need to reach a full energy decarbonisation is well known. Heating and cooling consumption is almost half of the global energy end-use. Thus, development of low-carbon and highly efficient power-to-heat technologies ... -
Kinematic design of a new four degree-of-freedom parallel robot for knee rehabilitation
Rehabilitation robots are increasingly being developed in order to be used by injured people to perform exercise and training. As these exercises do not need wide range movements, some parallel robots with lower mobility ... -
