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 …

In the last ten years, advances in experimental techniques have enabled remarkable
discoveries of how the dynamics of thin gas films can profoundly influence the behavior of …

Levitation and controlled motion of matter in air have a wealth of potential applications
ranging from materials processing to biochemistry and pharmaceuticals. We present a …

Liquid drops hitting solid surfaces deform substantially under the influence of the ambient air
that needs to be squeezed out before the liquid actually touches the solid. Nanometer-and …

Direct numerical simulations are performed to investigate the multiscale flow physics of
binary droplet collision over a wide range of Weber numbers and impact factors. All possible …

We present a theory on the coalescence of 2 spherical liquid droplets that are initially
stationary. The evolution of the radius of a liquid neck formed upon coalescence was …

Turbulent flows laden withlarge, deformable drops or bubbles are ubiquitous in nature and a
number of industrial processes. These flows are characterized by physics acting at many …

A model is developed for liquid drop impact on a solid surface that captures the thin film gas
flow beneath the drop, even when the film's thickness is below the mean free path in the gas …

The off-center collision of binary equal-sized alumina droplets has been investigated by
employing a three-dimensional direct numerical simulation method which involves the …

Dental enamel is a mineralized extracellular matrix, and enamel defect is a common oral
disease. However, the self‐repair capacity of enamel is limited due to the absence of cellular …
