Antunes, Liliana; Rojas-Castro, Madelyn; Lozano, Marcos; Martínez-Baz, Iván; Leroux-Roels, Isabel; Borg, Maria-Louise; Oroszi, BeatrixWe estimated the effectiveness of the adapted monovalent XBB.1.5 COVID-19 vaccines against PCR-confirmed SARS-CoV-2 hospitalisation during the BA.2.86/JN.1 lineage-predominant period using a multicentre test-negative case-control study in Europe. We included older adults (≥ 65 years) hospitalised with severe acute respiratory infection from November 2023 to May 2024. Vaccine effectiveness was 46% at 14-59 days ...
Early COVID‐19 XBB.1.5 Vaccine Effectiveness Against Hospitalisation Among Adul...
Antunes, Liliana; Mazagatos, Clara; Martínez‐Baz, Iván; Naesens, Reinout; Borg, Maria‐Louise; Petrović, Goranka; Fatukasi, Terra; Jancoriene, LigitaWe conducted a multicentre test-negative case–control study covering the period from October 2023 to January 2024 among adult patients aged ≥18 years hospitalised with severe acute respiratory infection in Europe. We provide early estimates of the effectiveness of the newly adapted XBB.1.5 COVID-19 vaccines against PCR-confirmed SARS-CoV-2 hospitalisation. Vaccine effectiveness was 49% overall, ranging between ...
On the chemistry, photocatalytical, and corrosion behavior of co-sputtered tant...
Cristea, Daniel; Croitoru, Cătălin; Marin, Alexandru; Dobromir, Marius; Ursu, Elena Laura; Velicu, Ioana Laura; Tiron, Vasile; Crăciun, ValentinDirect current magnetron co-sputtered titanium and tantalum based oxynitride coatings (TaTiON) were analyzed in terms of their chemistry, surface morphology, surface energy, photocatalytic activity, and corrosion resistance. The variable parameter for the deposition was the applied current on each target, changing between 0.75A and 0.25A for the Ta target, and from 0.25A to 0.75 A for the Ti target, to obtain a...
Tantalum oxynitride thin films: Assessment of the photocatalytic efficiency and...
Cristea, Daniel; Cunha, Luís; Gabor, Camelia; Ghiuta, Ioana; Croitoru, Catalin; Marin, Alexandru; Velicu, Laura; Besleaga, Alexandra; Vasile, BogdanTantalum oxynitride thin films have been deposited by reactive magnetron sputtering, using a fixed proportion reactive gas mixture (85% N<sub>2</sub> + 15% O<sub>2</sub>). To produce the films, the partial pressure of the mixture in the working atmosphere was varied. The characteristics of the produced films were analyzed from three main perspectives and correspondent correlations: the study of the bonding stat...
