  • Coalescence-induced jumping of droplets on superomniphobic

    Coalescence-induced Jumping Of Droplets On Superomniphobic

    when two liquid droplets coalesce on a superrepellent surface, the excess surface energy is partly converted to upward kinetic energy, and the coalesced droplet jumps away from the surface. however, the efficiency of this energy conversion is very low. in this work, we used a simple and passive technique consisting of superomniphobic surfaces with a macrotexture (comparable to the droplet

    Coalescence-induced Jumping Of Droplets On Superomniphobic

    using this high energy conversion efficiency, we can now achieve coalescence-induced jumping of low–surface tension droplets (e.g., n-tetradecane with ρ ≈ 760 kg m −3, μ ≈ 2.1 mpa·s, γ lv ≈ 26.6 mn m −1, and r 0 ≈ 480 μm; see fig. 4, a and b, and movie s4) and high-viscosity droplets (e.g., water + 90% glycerol with ρ ≈

    Aerosols, Droplets, And Airborne Spread: Everything You

    transmission through airborne aerosols is about 100 to 1000 times less likely than the other two routes (telllier 2009) that is reassuring. however, it is a mistake to take that line of reasoning too far. just because droplet spread is more likely, doesn’t mean that airborne spread should be ignored.
