The paper titled Investigation of the confinement effect on the evaporation behavior of a droplet pinned on a micropillar structure, which focused on the study of the diffusion confinement effect imposed by the bottom substrate and the sidewall of the micropillar through numerical simulations and experimental investigations got published on Journal of Colloid and Interface Science. The simulation […]

In scaling computer performance, closely integrating heterogeneous components in a single system-inpackage assembly provides faster signal communication and a tighter footprint – but also generates more heat: state-of-the art microelectronic devices can produce more than 1 kW square-cm. The next generation high-powered electronics will need two-phase liquid cooling, such as droplet evaporation, which utilizes the

Poster presentation at 2019 Gordon Research Seminar/Conference on Micro and Nanoscale Phase Change Heat Transfer.

The NSF grant will go to the nanoscale energy and interfacial transport research based mentoring program to increase underrepresented minority students in STEM. This program explores how to motivate students from the Saint Louis area, and in particular underrepresented minorities, to pursue careers in science, technology, engineering and mathematics (STEM) fields. A series of integrated

The $86,419 grant from Google Inc. will be used for research on creating better cooling strategy for data center infrastructure. Within one year, we aim to develop micropillar arrays, which ultimately will measure 1 to 5 microns in diameter with optimal shapes to promote evaporative cooling. For more information click here.

Dr. Damena Agonafer is invited to give a seminar talk at Carnegie Mellon University. Dr. Agonafer will present a talk titled “Evaporation from Asymmetric Microdroplets”.

Technical presentation at ASME IMECE conference on “Fundamental Mechanisms of Evaporation Kinetics of Non-Spherical Microdroplets Confined by Asymmetric Micropillar Structures”

The $10,000 seed grant from the Alfred P. Sloan Foundation will be used to support our research in the fundamental transport mechanism of microdroplet evaporation from nanocoated microporous structures for low and high surface tension liquids. For more information click here.

Technical presentation at ASME InterPACK conference on: (1) Numerical Investigation of Shape Effect on Microdroplet Evaporation; (2) Investigation of the Role of Surface Nanocoatings and Two-Phase Evaporative Heat Transfer using Molecular Dynamic Simulations

Our research on porous membrane design is getting more media coverage. In April 12, 2018, IEEE Spectrum featured our work in an article titled “The Electronics Cooling System 400 Years in the Making”. IEEE Spectrum Article
