Transparent materials such as glasses and some polymers play an essential role in our
daily life. Indeed, it is well known that their application in mirrors, windows, automobile …

The coalescence process of droplets and, more recently, of liquid marbles, has become one
of the most essential manipulation schemes in digital microfluidics. This process is …

Dew is the condensation of water vapor into liquid droplets on a substrate. It is characterized
by an initial heterogeneous nucleation on a substrate and a further growth of droplets. The …

The growth dynamics of water drops condensed on a superhydrophobic geometrically
patterned surface were studied. Drop size evolution at early and intermediate times is self …

We investigate experimentally and theoretically the coalescence dynamics of two spreading
droplets on a highly wettable substrate. Upon contact, surface tension drives a rapid motion …

Condensation on rough or superhydrophobic substrates can induce wetting behavior that is
quite different from that of deposited or impinging drops. We investigate the growth dynamics …

The world's ever-increasing need for fresh water has led to the use of non-conventional
sources such as rain and fog water collection. Although rain water collection is relatively …

We are thankful to our doctoral and master's students who worked with us in the areas of
interfacial transport phenomena and phase-change. We have worked closely with Dr …

On superhydrophobic (SHPo) surfaces, either of two wetting states the Cassie state (ie,
nonwetted state) and the Wenzel state (ie, wetted state) can be observed depending on …

Experimental observations of dropwise condensation of water vapor on a chemically
textured surface of glass and its detailed computer simulation are presented. Experiments …
