Fundamental limits of jumping droplet heat transfer

Applied Physics Letters, 2020
Liquid-vapor phase-change cooling has a significant potential to facilitate the development of highly dense electronics by leveraging latent heat during the phase transition to remove heat from hotspots. A promising form of liquid–vapor phase-change cooling is coalescence-induced jumping droplet condensation, where droplet growth results in coalescence

Exploiting the Twisted Intramolecular Charge Transfer Effect to Construct a Wash-Free Solvatochromic Fluorescent Lipid Droplet Probe for Fatty Liver Disease Diagnosis.

Analytical Chemistry, 2022
The prominent pathological feature of fatty liver disease lesions is excessive fat accumulation in lipid droplets in hepatocytes. Thus, developing fluorescent lipid droplet-specific probes with high permeability and a high imaging contrast provides a ...

Oxygen Transfer From Falling Water Droplets

Journal of the Sanitary Engineering Division, 1969
Overall oxygen transfer coefficients are obtained for deaerated water droplets falling freely through the atmosphere with and without 50 ppm. of a synthetic detergent. Drop distances ranged from 0 to 13 ft, and droplet surface areas varied from 0.47 to 0.55 cm\U2\N.

Droplet heat transfer on micro-post arrays: Effect of droplet size on droplet thermal characteristics

International Journal of Heat and Fluid Flow, 2017
Abstract Heat transfer towards a water droplet from hydrophobic micro-post array surface is considered while mimicking the environmental temperatures. Micro-post arrays are created on a silicon wafer surface via lithography technique. The textured surfaces are replicated by polydimethylsiloxane (PDMS) to achieve an optical transmittance.

Study of Ion Transfer Coupling with Electron Transfer by Hydrophilic Droplet Electrodes

Analytical Chemistry, 2015
In a hydrophilic droplet three-electrode system, electroactive species within the droplet play very important roles in the electron-transfer (ET) process on the solid/electrolyte interface, which can then induce an ion-transfer (IT) reaction at the liquid/liquid interface.

Radiative Transfer and Cloud Droplet Growth

Journal of the Atmospheric Sciences, 1979
Abstract Two papers, Roach (1976) and Barkstrom (1978), estimating the significance of radiative transfer on cloud (or fog) droplet growth have recently appeared. While their Principal conclusions are in broad quantitative agreement, it is worth commenting briefly on such differences of emphasis as do exist.
