We carried out experimental and numerical investigations on the axisymmetric spreading
evolution of dynamic spin coating with a single drop of ethanol. The results show that the …

Mixed wettability develops naturally on a pore scale in oil reservoirs after primary drainage.
The invading oil fills pore interiors that become oil-wet by asphaltene deposition, while the …

We present a theoretical study of viscous slug motion inside a microscopically rough
capillary tube, where pronounced stick–slip motion can emerge at slow displacement rates …

Spin coating is a kind of economically friendly technology accompanied by outstanding
application performance, which has been widely adopted in the functional thin film …

We observed the instability of a few-nanometer-thick water film encapsulated inside a
graphene nanoscroll using transmission electron microscopy. The film, that was left after …

The withdrawal of a liquid or the translation of a liquid slug in a capillary tube leads to the
deposition of a thin film on the inner wall. When particles or contaminants are present in the …

The displacement of a suspension of particles by an immiscible fluid in a capillary tube or in
porous media is a canonical configuration that finds application in a large number of natural …

Imbibition in a porous medium plays a central role in diverse energy, environmental, and
industrial processes. In many cases, the medium has multiple parallel strata of different …

We theoretically study the Plateau-Rayleigh instability of a thin viscous film covering a fiber
consisting of a rigid cylindrical core coated with a thin compressible elastic layer. We …

Atomic layer deposition (ALD) offers excellent controllability of spatial uniformity, film
thickness at the Angstrom level, and film composition even for high-aspect-ratio …
