Anyone who has enjoyed a glass of wine has undoubtedly noticed the regular pattern of liquid beads that fall along the inside of the glass, or ‘tears of wine.’ The phenomenon is the result of a flow against gravity along the liquid film on the glass, which is induced by an interfacial tension gradient. It is generally accepted that the interfacial tension gradient is due to a composition gradient resulting from the evaporation of ethanol. We re-examine the tears of wine phenomenon and investigate the importance of thermal effects, which previously have been ignored. Using a novel experiment and simple model we find that evaporative cooling contributes significantly to the flow responsible for wine tears, and that this phenomenon occurs primarily because of the thermodynamic behavior of ethanol-water mixtures. Also, the regular pattern of tear formation is identified as a well-known hydrodynamic instability.

“…5 (b), it can be seen that for refrigerant-oil mixture, the protuberant liquid film occurs in front of the meniscus, which is similar to the well-known phenomenon named "Tears of wine" [29][30][31][32][33].…”

“…These researches have shown that during the evaporation of water-alcohol mixture, the liquid near the surface is driven upward in the form of thin film, and then downward in the form of regular rows of drops known as "tears of wine" [29][30][31]. This phenomenon has been attributed to the Marangoni convection effect, which is caused by the faster evaporation of alcohol and the difference of surface tension between alcohol and water [32][33].…”

“…Wetting-drying phenomena abound in nature (e.g., the "coffee ring" effect, [ 20 ] tears of wine, [ 21 ] wetting of fi bers. [22][23][24] The capillary forces underlying these phenomena could be used to control hierarchical self-assembly processes.…”

The wetting and drying of drops on flexible fibers occurs ubiquitously in nature, and the capillary force underlying this phenomenon has motivated our great interest in learning how to direct supramolecular self-assembly. Here, the hierarchical co-assembly of two aromatic peptides, diphenylalanine (FF) and ferrocene-diphenylalanine (Fc-FF), is reported via sequential, combinatorial assembly. The resulting dandelion-like microstructures have highly complex architectures, where FF microtube arrays serve as the scapes and the Fc-FF nanofibers serve as the flower heads. Homogeneous FF microtubes with diameters tailored between 1 and 9 μm and wall thickness ranging from 70 to 950 nm are initially formed by controlling the degree of supersaturation of the FF and the water content. Once the FF microtubes are formed, the growth of the dandelion-like microstructures is then driven by the capillary force, derived from the wetting and drying of the Fc-FF solution on the FF microtubes. This simple and ingenious strategy offers many opportunities to develop new and creative methods for controlling the hierarchical self-assembly of peptides and thus building highly complex nano and microstructures.
