TL;DR: In this article, the authors focus on recent experimental and theoretical studies, which aim at unraveling the underlying physics, characterized by the delicate interplay of liquid inertia, viscosity, and surface tension, but also the surrounding gas.

TL;DR: Topological texture on superhydrophobic materials is critical in stabilizing the vapour layer and thus in controlling—by heat transfer—the liquid–gas phase transition at hot surfaces, and can potentially be applied to control other phase transitions.

TL;DR: In this article, the authors present recent technological advances in charge-coupled-device ultra-high-speed video cameras and their applications in experimental fluid mechanics, emphasizing the dynamics of drops and bubbles.

TL;DR: In this article, high-speed video imaging reveals that the coalescence process is not instantaneous, but rather takes place in a cascade where each step generates a smaller drop, and the time associated with each partial coalescence scales with the surface tension time scale.

TL;DR: This work presents a new method based on blade coating of a blend of conjugated small molecules and amorphous insulating polymers to produce OTFTs with consistently excellent performance characteristics, demonstrating that careful control over phase separation and crystallization can yield solution-printed polycrystalline organic semiconductor films with transport properties and other figures of merit on par with their single-crystal counterparts.
