This can help to avoid transducers limitations in terms of both center frequency and frequency bandwidth. The proposed set up consist of low frequency and narrowband excitation, harmonic generation in the air and the use of a wide band receiver. The setup configuration requirements are analyzed and described in detailed in this study. A comparison of the proposed technique results with linear conventional wideband air-coupled measurements demonstrates the potential of the presented method as a less demanding alternative in terms of equipment needs and time required. This can be of special interest for the deployment of solutions based on MEMs transducers, mainly PMUTs, that show some limitations in the maximum frequency and bandwidth when operating in air.},\n bibtype = {article},\n author = {Fariñas, Lola and Álvarez-Arenas, Tomás E.

Samples with five distinct infill (Solid, Gyroid, Rectangular, Triangular, and Hexagonal) were fabricated and subjected to a water immersion protocol based on the ASTM D570-98 standard. The study measured weight absorption and analyzed changes in both mechanical and ultrasonic properties over time. Weight absorption results showed that Solid infill samples absorbed significantly more moisture (~12%) than those with 50% infill density. Dynamic mechanical analysis (DMA) revealed that moisture absorption caused a largely irreversible decrease in the storage modulus across all samples, indicating a permanent plasticizing effect on the material. The ACU measurements demonstrated their sensitivity to identify the unique characteristics of each infill pattern and their ability to monitor moisture-induced changes. An increase in attenuation and a decrease in longitudinal velocity were observed in all samples, with the most pronounced attenuation in the Solid and Hexagonal fill. Notably, the Triangular samples showed the greatest impact, losing the transmission signal after 24 hours of immersion. It is concluded that the ACU technique has the potential to be used as a robust, rapid and non-destructive method for initial quality control and integrity monitoring of 3D-printed carbon fiber-reinforced nylon components.},\n bibtype = {inproceedings},\n author = {Sánchez-Marcos, Iñigo and Achiaga, Beatriz and Fariñas, Lola},\n doi = {10.1109/IUS62464.2025.11201347},\n booktitle = {2025 IEEE International Ultrasonics Symposium (IUS)}\n}

The proposed approach is based on air-coupled ultrasonic thickness resonance spectroscopy, which allows estimation of key parameters like longitudinal velocity, attenuation, and Q-factor. To validate the sensitivity of the proposed method, we compared resin samples with and without 3% MgO thickener under controlled conditions. Samples with thickener exhibited a consistent decrease in Q-factor, with significant slope changes around day 3 and day 7. This reduction, coupled with increasing attenuation, reflects early molecular interactions and correlates with expected viscosity increase. This marks the beginning and end of the key maturation stage temporal window. In contrast, samples without thickener showed negligible changes. Notably, longitudinal velocity remained stable in both cases, indicating minimal variation of the elastic modulus along the sample height during this phase. These findings confirm non-contact resonant ultrasound spectroscopy sensitivity to thickener-induced viscoelastic changes, offering a real-time, non-destructive tool for monitoring pre-cure resin states.},\n bibtype = {inproceedings},\n author = {Fariñas, Lola and Sánchez-Marcos, Iñigo and Achiaga, Beatriz and Camacho-Iglesias, Marta and Xypolias, Georgios and García-Etxabe, Rafael},\n doi = {10.1109/IUS62464.2025.11201583},\n booktitle = {2025 IEEE International Ultrasonics Symposium (IUS)}\n}

This can help to avoid transducers limitations in terms of both center frequency and frequency bandwidth. The proposed set up consist of low frequency and narrowband excitation, harmonic generation in the air and the use of a wide band receiver. The setup configuration requirements are analyzed and described in detailed in this study. A comparison of the proposed technique results with linear wideband air-coupled measurements demonstrates the potential of the presented method as a less demanding alternative in terms of equipment needs and time required. This can be of special interest for the deployment of solutions based on MEMs transducers, mainly PMUTs, that show some limitations in the maximum frequency and bandwidth when operating in air.},\n bibtype = {inproceedings},\n author = {Fariñas, María Dolores and Gómez Álvarez-Arenas, Tomás},\n doi = {10.1109/IUS51837.2023.10307535},\n booktitle = {2023 IEEE International Ultrasonics Symposium (IUS)}\n}

In this work, the design and fabrication of multiple particle-loaded polymer composites, including micronized rubber from end-of-life tires, is studied. The integration of these composites as part of ultrasonic transducers can further expand the functionality of the piezoelectric material in the transducer in terms of sensitivity, bandwidth, ringing and axial resolution and help to facilitate the fabrication and use of phantoms for echography. The adopted approach is a multiphase and multiscale one, based on a polymeric matrix with a load of recycled rubber and tungsten powders. A fabrication procedure, compatible with transducer manufacturing, is proposed and successfully used. We also proposed a modelling approach to calculate the complex elastic modulus, the ultrasonic damping and to evaluate the relative influence of particle scattering. It is concluded that it is possible to obtain materials with acoustic impedance in the range 2.35–15.6 MRayl, ultrasound velocity in the range 790–2570 m/s, attenuation at 3 MHz, from 0.96 up to 27 dB/mm with a variation of the attenuation with the frequency following a power law with exponent in the range 1.2–3.2. These ranges of values permit us to obtain most of the material properties demanded in ultrasonic engineering.</p>},\n bibtype = {article},\n author = {Genovés, Vicente and Fariñas, María Dolores and Pérez-Aparicio, Roberto and Saiz-Rodríguez, Leticia and Valentín, Juan López and Álvarez-Arenas, Tomás Gómez},\n doi = {10.3390/polym14173614},\n journal = {Polymers},\n number = {17}\n}

Thus, ultrasonic parameters, such as maximum wave amplitude and ultrasound velocity, and textural ones, such as hardness, elastic modulus and relaxation capacity, were measured on avocado slices. During ripening, avocado reduced its elastic modulus (from 2.29 ± 0.75 to 0.16 ± 0.08 MPa), became softer and became more viscoelastic, which was well described from zero and first-order kinetic models. These changes increased ultrasound attenuation, decreasing the maximum amplitude of the ultrasonic signal (from 336.6 to 55.4 V/m), while the ultrasonic velocity remained constant, between 320.1 ± 6.9 and 316.4 ± 82.6 m/s. Thereby, the maximum ultrasonic amplitude, which adequately correlated with textural parameters (ravg = 0.85), could be used to assess the post-harvest ripening on avocado slices.},\n bibtype = {article},\n author = {Fariñas, Lola and Sanchez-Torres, Eduardo A. and Sanchez-Jimenez, Virginia and Diaz, Ricardo and Benedito, Jose and Garcia-Perez, Jose V.},\n doi = {10.1016/j.jfoodeng.2020.110266},\n journal = {Journal of Food Engineering},\n number = {July 2020}\n}

In this study, ultrasonic parameters directly obtained from experimental measurements in the field using NC-RUS - such as resonant frequency (fres), velocity (v) and Q-factor - were evaluated as potential water stress indicators in Citrus plants. The experiments were carried out in two-year-old mandarin trees (Citrus clementina Hort. ex Tan. ‘Clemenules’) grown in pots in an open greenhouse where two different groups of plants were tested: a Control group (full irrigation) and a Drought Stress group (DS) whose irrigation was withdrawn during 7 days, followed by a 16 days recovery period. Soil water content, leaf water potential (Ψleaf) and the considered ultrasonic parameters were measured in the same leaves. fres detected changes between control and DS at day 7 without irrigation. Conversely, v showed differences after day 3, which were statistically significant at day 7, enabling discrimination between C and DS groups. Hence, Q-factor was the ultrasonic parameter that showed statistically significant differences between C and DS groups at days 3 and 7. Consequently, Signal Intensity in Q during the drought treatment showed a similar evolution to Ψleaf, although with slightly lower performance. However, Q-factor sensitivity excels Ψleaf at each day studied. Finally, a linear correlation (R2=0.57) between Ψleaf and Q-factor of all experimental data measured in DS group plants along the drought treatment was found. In conclusion, the ultrasonic parameters obtained using NC-RUS and in particular the Q-factor, demonstrated to be potential new water stress indicators in Citrus trees, with the novelty of being non-destructive, non-invasive and rapid. Future work should explore its suitability for its use in irrigation scheduling for Citrus trees.},\n bibtype = {article},\n author = {Fariñas, María Dolores and Martínez-Gimeno, María Amparo and Badal, Eduardo and Tasa, María and Bonet, Luis and Manzano-Juárez, Juan and Pérez-Pérez, Juan G.},\n doi = {10.1016/j.agrformet.2021.108651},\n journal = {Agricultural and Forest Meteorology},\n number = {April}\n}

In this study, we developed a broadly applicable and quantitative classification workflow that identifies reactivity cliffs in 11 Ni- and Pd-catalyzed cross-coupling datasets using monodentate phosphine ligands. A distinctive ligand steric descriptor, minimum percent buried volume [%Vbur (min)], is found to divide these datasets into active and inactive regions at a similar threshold value. Organometallic studies demonstrate that this threshold corresponds to the binary outcome of bisligated versus monoligated metal and that %Vbur (min) is a physically meaningful and predictive representation of ligand structure in catalysis.},\n bibtype = {article},\n author = {Gómez Álvarez-Arenas, Tomás E. and Fariñas, María D. and Ginel, Alba},\n doi = {10.1016/j.ultras.2021.106556},\n journal = {Ultrasonics},\n number = {33}\n}

The potential of additive manufacturing (AM) to revolutionize aspects of industrial production is widely recognized. AM can create objects with non-uniform properties by varying the ratio between deposited materials or altering the internal structure of the object. Amongst many possibilities, such AM objects could benefit the design and fabrication of different passive components of ultrasonic transducers, e.g. backing material, lenses and matching layers. The acoustic properties of AM objects produced using the Polyjet and Fused Deposition Methods were characterized. Initial results suggest that these technologies can easily produce objects with a wide range of tuned acoustic properties by varying either the internal structure or the material composition.},\n bibtype = {inproceedings},\n author = {Farinas, M.D. and Alvarez-Arenas, T.E.G. and Cummins, G. and Desmulliez, M.P.Y. and Seetohul, V. and Cochran, S.},\n doi = {10.1109/ULTSYM.2016.7728770},\n booktitle = {2016 IEEE International Ultrasonics Symposium (IUS)}\n}

These networks exhibit a unique hierarchical architecture in which thin layers with honeycomb-like structure and internal strut length in the order of 1–10 µm in size are aligned with an interlayer spacing ranging between 15 and 50 µm. The resulting structures exhibit strengths (up to 3MPa) and stiffness (up to 0.3 GPa) that are higher than aerogels of similar density and comparable to other ceramic microlattices fabricated by vapor deposition. Furthermore, this wet processing technique allows the fabrication of large-size samples that are stable at high temperature, with acoustic impedance that can be manipulated over one order of magnitude (0.03–0.3MRayl), electrically conductive and with very low thermal conductivity. The approach can be extended to other ceramic materials and opens new opportunities for the fabrication of ultralight structures with unique mechanical and functional properties in practical dimensions.},\n bibtype = {article},\n author = {Ferraro, Claudio and Garcia-Tuñon, Esther and Rocha, Victoria G. and Barg, Suelen and Fariñas, Maria Dolores and Alvarez-Arenas, Tomas E.

Four different widely available species, both monocots and dicots and evergreen and deciduous, with different leaf features (shape, size, thickness, flatness, vascular structure), were selected to test the technique. After a sudden decrease in light intensity, and depending on the species, there was a relative increase in the thickness resonant frequency from 8% to 12% over a 25- to 50-min period. After sudden watering, the relative increase in the resonant frequency varied from 5% to 30% and the period from 10 to 400 min. Finally, along the diurnal cycle, the measured relative variation is between 4% and 10%. The technique revealed differences in both the amplitude of the frequency oscillations and the kinetics of the leaf response for different species and also within the same species, but for specimens grown under different conditions that present different cell structures at the tissue level. The technique can be equally applied to the leaves of any species that present thickness resonances.},\n bibtype = {article},\n author = {Fariñas, Maria Dolores and Sancho Knapik, Domingo and Peguero Pina, Jose Javier and Gil Pelegrin, Eustaquio and Álvarez-Arenas, Tomás E.

Obtaining TLP through the standard pressure-volume (p-v) curve method in a large set of species is highly time-consuming and somewhat subjective. To solve this problem, we present an objective and a less time-consuming technique based on the leaf resonance able to calculate the relative water content (RWC) at TLP (RWCTLP). This method uses air-coupled broadband ultrasonic spectroscopy to obtain the sigmoidal relation between RWC and the standardized resonant frequency (f/fo). For the 13 species measured, the inflexion point of the RWC-f/fo relationship ( ) was not statistically different from the value of RWC at the TLP obtained with the p-v curves (RWCTLP p-v).},\n bibtype = {article},\n author = {Sancho-Knapik, Domingo and Peguero-Pina, José Javier and Farinas, M.

Generous watering may reduce grape quality so irrigation should be precisely regulated through the development of new methods of accurate irrigation scheduling based on plant ‘stress sensing’. Two new methods, the reflectivity in the S-band and the broadband ultrasonic spectroscopy, can be used as non-invasive and reproducible techniques for the study of plant water relations in . On one hand, the measurement of reflectance at frequencies around 2.4GHz gives an excellent accuracy when the changes in the existing area (S) between two reflectance curves are correlated with the relative water content (RWC). On the other hand, an improvement of the broadband ultrasonic spectroscopy based on the enlargement of the analysis frequency window provides, apart from the determination of the turgor loss point (TLP), additional information about the leaves without additional computational cost or additional leaf information requirements. Before TLP, the frequency associated with the maximum transmittance (f/fo), the macroscopic elastic constant of the leaf in the Z direction (c33) and, specially, the variation of the attenuation coefficient with the frequency (n), were highly correlated with changes in RWC. Once turgor is lost, a shift in the parameters directly related to the attenuation of the signal was also observed. The use of both techniques allows for a more convincing knowledge of the water status in .},\n bibtype = {article},\n author = {Sancho-Knapik, Domingo and Peguero-Pina, José Javier and Medrano, Hipólito and Fariñas, María Dolores and Álvarez-Arenas, Tomás Gómez and Gil-Pelegrín, Eustaquio},\n doi = {10.1111/ppl.12007},\n journal = {Physiologia Plantarum},\n number = {4}\n}
