摘要: Electrosprays have diverse applications including protein analysis, electrospinning, and nanoencapsulation for drug delivery. We show that a variety of electrospray regimes exhibit fundamental analogy with the nonlinear dynamics dripping faucet. The applied voltage in electrosprays results additional period doublings temporal order-chaos-order transitions. Attractors return maps logarithmic self-similarity time, suggesting self-similar capillary waves on meniscus. bifurcations ejection time can be explained by phase variations between pinch-off conditions mode changes due to contact angle variations.
