Bacteria are among the oldest and most abundant species on Earth. Bacteria successfully
colonize diverse habitats and play a significant role in the oxygen, carbon, and nitrogen …

Drying drops of colloidal dispersions have attracted attention from researchers since the
nineteenth century. The multiscale nature of the problem involving physics at different …

Fluid transport that is driven by gradients of pressure, gravity, or electro-magnetic potential is
well-known and studied in many fields. A subtler type of transport, called diffusiophoresis …

The shape of deposits obtained from drying drops containing colloidal particles matters for
technologies such as inkjet printing, microelectronics, and bioassay manufacturing. In this …

A macroscopic evaporating water droplet with suspended particles on a solid surface will
form a ring-like structure at the pinned contact line due to induced capillary flow. As the …

In nature, helical macromolecules such as collagen, chitin and cellulose are critical to the
morphogenesis and functionality of various hierarchically structured materials,,. During …

We study the influence of electrowetting on the formation of undesired solute residues, so-
called coffee stains, during the evaporation of a drop containing non-volatile solvents …

Control of structures in soft materials with long-range order forms the basis for applications
such as displays, liquid-crystal biosensors, tunable lenses, distributed feedback lasers …

DOI: 10.1002/adma. 201505617 nonvolatile solutes normally leaves a ring of solute
deposited on the surface instead of a uniform distribution and it is the well-known coffee-ring …

An efficient way to precisely pattern particles on solid surfaces is to dispense and evaporate
colloidal drops, as for bioassays. The dried deposits often exhibit complex structures …
