During the last two decades, engineering motion with small-scale matter has received much
attention in several areas of research, ranging from supramolecular chemistry and colloidal …

The spontaneous spreading of non-volatile liquid droplets on solid substrates poses a
classic problem in the context of wetting phenomena. It is well known that the spreading of a …

Oil seepage and spills have lasting detrimental effects on the environment, especially on
nearby marine ecosystems. Despite quick and safe removal of contaminating oil being of …

We establish a tool for direct measurements of the work needed to separate a liquid from a
solid. This method mimics a pendant drop that is subjected to a gravitational force that is …

Cake appearance is an important attribute of freeze-dried products, which may or may not
be critical with respect to product quality (ie, safety and efficacy). Striving for “uniform and …

A rubber-like stretchable semiconductor with high carrier mobility is the most important yet
challenging material for constructing rubbery electronics and circuits with mechanical …

π-Conjugated organic semiconductors (OSCs) are the basic scaffold of organic
semiconductor devices. Solution processing is an effective way to promote the …

The motion of droplets under the influence of lithographically created anisotropic chemically
defined patterns is described and discussed. The patterns employed in our experiments …

The Marangoni effect—often invoked to describe the so-called “tears of wine”—is in essence
the mass transfer along an interface between two fluids due to a gradient of the surface …

Thermal management of flexible/stretchable electronics has been a crucial issue. Mass
supernumerary thermal heat is created in the repetitive course of deformation because of the …
