Evaporation‐Driven Solutal Marangoni Control of Rayleigh–Taylor Instability in Inverted Films

open access: yesAdvanced Science, EarlyView.
ABSTRACT Inverted liquid films are inherently unstable: gravity amplifies perturbations through the Rayleigh–Taylor instability (RTI), causing rupture and dripping. We show that selective evaporation in volatile binary mixtures can suppress, delay, or transform this instability by inducing solutal Marangoni stresses.

Tailoring the Crystallization Behavior of Mixed Lead‐Tin Mixed‐Halide Perovskites for Optimal‐Bandgap Solar Cells

open access: yesAdvanced Science, EarlyView.
Carefully tuning the composition of mixed lead‐tin mixed iodide‐bromide perovskites results in an optimal‐bandgap semiconductor for solar energy conversion. Homogenous crystallization of this perovskite involves a short time delay between deposition of the precursor solution and applying an antisolvent. Using a bulk additive and top surface passivation

Salt Water Drops Slide Faster: Ionic Modulation of Drop Friction

open access: yesAdvanced Science, EarlyView.
Salt ions markedly accelerate water drops on conductive substrates coated with nanometer‐thin hydrophobic layers. Across diverse electrolytes and surfaces, higher ion concentration consistently lowers kinetic friction by reducing contact angle hysteresis.
