## Description

- description: In the insect realm, liquids become traps due to capillary and viscous
    forces dominant at their scale. Yet, aphids eliminate the highly viscous honeydew
    droplets that they secrete, by coating them with hydrophobic wax powder which
    maintains an air layer between their body and the sticky liquid. These low-adhesion,
    highly mobile coated droplets, known as liquid marbles, enable manipulation of
    small liquid volumes which is useful in applications such as biomedical analysis
    where samples volume is limited, chemistry to reduce chemical waste, or digital
    microfluidics for large-scale cell culturing and drug testing. Despite numerous
    applications, the physical properties of liquid marbles remain largely unexplored.
    This article addresses the fundamental question of the stability and adhesion
    of hot liquid marbles on cooler substrates. We find that due to the temperature
    difference, condensation forms within the particle layer, eventually bridging
    the core liquid with the substrate where wettability then plays a role. Hot liquid
    marbles rupture on hydrophilic substrates but remain intact on hydrophobic ones;
    however, their adhesion increases with temperature difference due to increased
    liquid bridge density. This non-wetting failure, rupture and increased adhesion,
    can be suppressed by increasing the particles size, decreasing the liquid volatility
    or using superhydrophobic substrates.
