Droplet impact is a ubiquitous phenomenon in nature, daily life, and industrial processes. It
is thus crucial to tune the impact outcomes for various applications. As a special outcome of …

Supercooled droplet freezing on surfaces occurs frequently in nature and industry, often
adversely affecting the efficiency and reliability of technological processes. The ability of …

Silicone is frequently used as a model system to investigate and tune wetting on soft
materials. Silicone is biocompatible and shows excellent thermal, chemical, and UV stability …

Superhydrophobic surfaces are often seen as frictionless materials, on which water is highly
mobile. Understanding the nature of friction for such water-repellent systems is central to …

Liver failure is a fatal disease with a mortality rate of 80%. The only access to treat liver
failure is invasive operation, which is restricted by limited donor sources or high costs. Thus …

Droplets may rebound/levitate when deposited over a hot substrate (beyond a critical
temperature) due to the formation of a stable vapor microcushion between the droplet and …

Small water droplets or particles located at an oil meniscus typically climb the meniscus due
to unbalanced capillary forces. Here, we introduce a size-dependent reversal of this …

Recent studies have revealed the air-cushioning effect of droplet impact upon various
surfaces and although pure water droplets have extensively been studied, the air …

In this Letter, we systematically investigate the Leidenfrost temperature for hot solid
substrates with various thermal diffusivities and surface roughnesses. Based on the …

Sessile drops are ubiquitous and important in technological applications. While dynamics of
liquid drops have been studied under confinement, the possibility of creating sessile drops …
