תקציר

Growth of chemical droplets confined by a droplet placed on a superhydrophobic surface is demonstrated. FeCl₃ seed crystals were deposited on a polymer superhydrophobic surface. Droplets containing an aqueous solution of the potassium hexacyanoferrate (K₄Fe(CN)₆·3H₂O) were allowed to contact the seed crystals. Typical small-scale chemical gardens, similar to those grown in open vessels, were observed within 20μl droplets. Micrometrically scaled filaments were registered. The Laplace overpressure developed in the droplet was insufficient for suppressing the growth of chemical gardens. Addition of ethanol delayed the growth of chemical gardens.
