Tunable Self‐Emulsification Via Viscoelastic Control of Marangoni‐Driven Interfacial Instabilities (Small Methods 1/2026)

Back Cover A composite visual of the Marangoni bursting phenomenon, built from binarized cutouts of experimental snapshots arranged in an azimuthal pattern. Each segment captures the characteristic burst formed when a water-alcohol droplet spreads on an oil bath. To highlight the role of viscoelasticity, a continuous color gradient has been overlaid across the image, following the azimuthal direction. As the viewer moves clockwise, both the color and the polymer concentration, i.e., viscoelasticity, increase. More in article number 2500749, Sen and co-workers.
