    “…CONCLUSION: Short-term exposure to ambient air pollution (NO(2), O(3), and PM(10)) may be associated with an increased risk of daily cardiovascular and cerebrovascular admission, which may provide reliable evidence for further understanding of the potential adverse effects of air pollution on cardiovascular and cerebrovascular diseases.…”

    “…RT-PCR diagnosis using throat swab specimens had a failure rate of more than 22% in safely discharging COVID-19 patients who were otherwise still exhaling the SARS-CoV-2 by a rate of estimated ~1400 RNA copies per minute into the air. Direct surface contact might not represent a major transmission route, and lower positive rate of air sample (6.8%) was likely due to natural ventilation (1.6–3.3 m/s) and regular disinfection practices. …”

    “…Exhaled breath condensate (EBC) is safely collected in mechanically ventilated (MV) patients, but there are no guidelines regarding humidification of inhaled air during EBC collection. We investigated the influence of active and passive air humidification on EBC volumes obtained from MV patients. …”

    “…It takes its direction of travel from artist Brian Jungen’s ‘Cetology’ (2002), a whalebone sculpture made out of cut-up plastic garden chairs, which conjoins the times of earth and world history, as it hangs in the air of the art gallery, ‘as if’ exhibited in the natural history museum. …”

    “…Nevertheless, almost all those as‐prepared surfaces are only applicable for liquids with higher surface tension (γ > 25.0 mN m(−1)) in air. In this work, inspired by some natural models, such as lotus leaf, springtail skin, and filefish skin, switchable repellency for liquids (γ = 12.0–72.8 mN m(−1)) in both air and liquid is realized via employing 3D deformable multiply re‐entrant microstructures. …”

    “…One potential explanation is that people in some areas are more vulnerable to the coronavirus disease because of their worsened health conditions caused by long-term exposure to poor air quality. In this study, we investigate whether long-term exposure to air pollution increases the risk of COVID-19 infection in Germany. …”

    “…In 2020, Covid-19-related mobility restrictions resulted in the most extensive human-made air-quality changes ever recorded. The changes in mobility are quantified in terms of outdoor air pollution (concentrations of PM(2.5) and NO(2)) and the associated health impacts in four UK cities (Greater London, Cardiff, Edinburgh and Belfast). …”
