Exploration of the Solubility Hyperspace of Selected Active Pharmaceutical Ingredients in Choline- and Betaine-Based Deep Eutectic Solvents: Machine Learning Modeling and Experimental Validation
PublicationDeep eutectic solvents (DESs) are popular green media used for various industrial, pharmaceutical, and biomedical applications. However, the possible compositions of eutectic systems are so numerous that it is impossible to study all of them experimentally. To remedy this limitation, the solubility landscape of selected active pharmaceutical ingredients (APIs) in choline chloride- and betaine-based deep eutectic solvents was...

Polarised light pollution on river water surfaces caused by artificial light at night from illuminated bridges and surroundings
PublicationLight is the part of the electromagnetic spectrum visible to the human eye, and such electromagnetic waves can be polarised (Foster et al., 2018) (Supplementary Material). Generally, humans are not able to perceive polarised light, apart from some very specific situations (Haidinger, 1844), while several animals are able to perceive it (Foster et al., 2018). Polarisation can occur when unpolarised light is reflected or transmitted...
