A comprehensive model of electric-field-enhanced jumping-droplet condensation on superhydrophobic surfaces
… length, and allowing the use of external electric fields to enhance droplet removal and heat transfer, in what has been termed electric-field-enhanced (EFE) jumping-droplet condensation. However, achieving optimal EFE conditions for enhanced heat transfer requires capturing the details of …

Highly excited states of atomic potassium in an external electric field
… spectrum of potassium in an external electric field is examined. Detailed studies are made of the strengths, spacing, and polarization dependence of the quasi-bound Stark states lying above E = O. The results are interpreted as the first observation of electric field enhanced …

Design of novel drug delivery system and optimal dosage regimens
… Finally, the simultaneous application of an electric current and soluble microneedles were proposed for the first time. Preliminary experimental studies suggested that the electric field enhanced the flux by increasing drug diffusion and, thereby, the dissolution of the microneedles. One-, …

Developing an active, high-heat-flux thermal management strategy for power electronics via jumping-droplet phase-change cooling
… cooling for hot spots in compact electronics via electric-field-enhanced (EFE) jumping-droplet condensation. To test the viability of EFE condensation for electronic hot spot cooling, an experimental setup was developed to remove heat via droplet evaporation from single and multiple high-power …

Electrostatic charging of jumping droplets on superhydrophobic nanostructured surfaces : fundamental study and applications
… by observing droplet motion in a uniform electric field. The mechanism for the charge accumulation is associated with the formation of the electric double layer at the droplet-coating interface and subsequent charge separation during droplet jumping governed by the fast time scales of …

Development and characterization of micro/nano structured surfaces for enhanced condensation
… well as the demonstration of such surfaces for enhanced condensation heat transfer performance. We first studied droplet-surface interactions during condensation on superhydrophobic surfaces to understand the emergent droplet wetting morphology. We demonstrated the importance of considering …
