The COVID‐19 pandemic has disrupted modern urban ecosystems on an unprecedented scale. Many urban scholars have undertaken the challenge of documenting and analysing how this global health crisis has been experienced and coped with, resulting in a surge of studies on its impact on various cityscapes and domains of urban life. In this paper, we present findings from a scoping review of 138 articles on this subject published between the outbreak of the pandemic and the end of June 2022. Our review showcases scholarly accounts of cascading shifts that have occurred within urban ecosystems and provides a better understanding of conceptual and methodological alterations in research approaches. Because both the investigated impacts and the research strategies deal primarily with the consequences of losing the pre‐pandemic spatial, temporal, social, cultural, and political frames of reference, we adopt transdisciplinary disorientation theories as the review's interpretive framework. This step proves to be fruitful in mapping and interpreting crises and breakdowns and also in revealing how an unexpected planetary ordeal has reoriented pre‐pandemic trends in urban development and transformed cities and urban life alike. We suggest that the disorienting pandemic experience can serve as a potent legacy for urban futures. However, the scale and distribution of post‐pandemic reorientations across European cities and their residents cannot yet be fully comprehended. [ABSTRACT FROM AUTHOR]

Solvation processes on polar embedded stationary phases were investigated by determination of excess isotherms in binary acetonitrile/water mobile phase. The obtained results indicate the competitiveness of acetonitrile and water adsorption on heterogeneous surfaces of chemically bonded stationary phases. The calculation of excess isotherm as a volume of excessively accumulated solvent confirms the competitiveness of solvents' adsorption in qualitative and quantitative meaning. Corresponding excess isotherms of water and acetonitrile are symmetrical with respect to the x‐axis. It confirms that the displaced volume of acetonitrile is replaced by an equal volume of water and vice versa. Additionally, fitting the two‐site adsorption model to experimental data provides quantitative values with low experimental errors. The obtained results confirm the advantage of volumetric assumption of excess adsorption over direct adsorption layers of solvents, which is commonly postulated. [ABSTRACT FROM AUTHOR]
