The Cover Feature links molecular-level chemistry with real-world, green environments through a transparent round-bottom flask filled with a warm-toned liquid placed in a natural outdoor setting. Inside the flask, detailed chemical structures represent the key molecules discussed in the Concept by E. Müller and W. Kunz (DOI: 10.1002/cssc.202502326). In the background, an emulsion-like pattern appears, symbolizing a homogenized medium. The bright yellow flower, insect and leaves emphasize the connection to nature and sustainability.
Müller et al. (2026) studied this question.
