    Multimethodological Approach for the Evaluation of Tropospheric Ozone’s Regional Photochemical Pollution at the WMO/GAW Station of Lamezia Terme, Italy by Francesco D’Amico, Giorgia De Benedetto, Luana Malacaria, Salvatore Sinopoli, Arijit Dutta, Teresa Lo Feudo, Daniel Gullì, Ivano Ammoscato, Mariafrancesca De Pino, Claudia Roberta Calidonna

    Published 2025-05-01
    “…In this study, the behavior of O<sub>3</sub> at the site is assessed with remarkable detail using nine years (2015–2023) of data and correlations with surface temperature and solar radiation. The evaluations demonstrate non-negligible correlations between environmental factors, such as temperature and solar radiation, and O<sub>3</sub> concentrations, driven by peculiar patterns in local wind circulation. …”

    Design and Performance Evaluation of a Sub-6 GHz Multi-Port Coupled Antenna for 5G NR Mobile Applications by Cheol Yoon, Yunsub Lee, Wonmo Seong, Woosu Kim

    Published 2025-07-01
    “…The fabricated two-port prototype exhibited a measured voltage standing wave ratio below 3:1 across the n78 band on both ports, with the isolation levels attaining –12.4 dB and ECCs below 0.12. The radiation efficiency exceeded −6 dB across the operational band, and the radiation patterns were stable at 3.3, 3.5, and 3.8 GHz, confirming that the system was appropriate for MIMO deployment. …”

    Characterization of bi-layers formed over maraging steel 300 during aging process with steam atmosphere by GIXRD and SEM by Vanessa Sanches Pereira da Silva, José Roberto Ferreira Neto, Silvia Lucas Ferreira da Silva, Diogo Costa de Oliveira, Fábio de Camargo

    Published 2021-04-01
    “…GIXRD and scanning electron microscopy (SEM) were employed to identify and order the layered structure formed on four specimens of maraging steel grade 300 with different surface finishes that were previously solution annealed twice at (950 ± 5) °C for 1 h, air-cooled, and submitted to oxidation process under positive pressure around 1.5 kPa of steam at (480 ± 5) °C for 6 h followed by forced air cooling. The diffraction patterns were measured employing CuKα radiation and parallel beam, in step scan mode, using incident angles varying from 0.2º to 4.0º and 20º < 2θ < 85º. …”
