TL;DR: An approach that predicts a priori whether an arbitrary combination of solid and lubricant will repel a given impinging fluid is developed, thereby eliminating the need for unreliable low-surface-energy coatings and resulting in LIS repelling the lowest surface tension impinge fluid reported to date.

TL;DR: Experimental measurements of heat transfer performance during hydrocarbon condensation on a LIS enhances heat transfer by ≈450% compared to an uncoated surface, and a failure mechanism whereby shedding droplets depleted the lubricant over time is highlighted.

TL;DR: The design, fabricated, and experimentally characterized a microfluidic device for ultra-high heat flux dissipation using evaporation from a nanoporous silicon membrane, suggesting that evaporative membrane-based approaches can be promising towards realizing an efficient, high flux thermal management strategy over large areas for high-performance electronics.

TL;DR: A theoretical framework to elucidate evaporation and transport within nanopores is presented by incorporating nonequilibrium effects due to the deviation from classical kinetic theory by including the nonlocal effects arising from phase change in nanoporous geometries.

TL;DR: This work experimentally demonstrated a unifying relationship between dimensionless flux and driving potential for evaporation kinetics under different working conditions, which provides a general figure of merit for evaporative heat transfer as well as design guidelines for achieving efficient evAPoration in applications such as water purification, steam generation, and thermal management.
