Deposition Patterns of Evaporating Sodium Alginate Sessile Droplets Cross‐Linked by Calcium Chloride

Inside front cover: In article 2300171 by Vahid Bazargan and co-workers, the evaporation of sodium alginate sessile droplets in the presence of calcium chloride as the cross-linker is investigated. Results show that the final deposition pattern can be determined by the relative concentration (RC) of calcium chloride to sodium alginate, which represents the number of colloidal particles or degree of cross-linking.
