Welcome

Welcome to the MIT Device Research Laboratory (DRL) under the direction of Dr. Evelyn Wang in the Mechanical Engineering Department at MIT.

The DRL combines fundamental studies of micro and nanoscale heat and mass transport processes with the development of novel nanostructured materials to create innovative solutions in thermal management, thermal energy storage, solar thermal energy conversion, and water desalination. We leverage state-of-the-art micro/nanofabrication, unique measurement, and model prediction capabilities to enable mechanistic insights into complex fluid, interfacial, and thermal transport processes. This approach has led to new and important functionalities to enhance heat and mass transfer for various applications.

11/18/2020: A Passive High-Temperature High-Pressure Solar Steam Generator for Medical Sterilization

Congratulations to Lin Zhao, Bikram Bhatia, Lenan Zhang, Elise Strobach, Arny Leroy, Sungwoo Yang as well as their collaborators for their recent work on A Passive High-Temperature High-Pressure Solar Steam Generator for Medical Sterilization, which was featured on MIT News and Nature Research Highlights! In this work, we demonstrated a passive solar thermal device mostly built from low-cost off-the-shelf components capable of delivering saturated and pressurized steam to drive sterilization cycles even under hazy and partly cloudy weather. Enabled by an optimized ultra-transparent silica aerogel, the device utilizes an efficient thermal concentration strategy to locally increase the heat flux and temperature obviating the need for active optical concentrators. With almost 2× higher energy efficiency (47%) than those previously reported at 100°C, the device demonstrated successful sterilization in a field test performed in Mumbai, India. In addition to enabling passive sterilization, this work promises the development of solar thermal energy systems for saturated steam generation in energy conversion, storage, and transport applications.

10/14/2020: Dual-Stage Atmospheric Water Harvesting Device for Scalable Solar-Driven Water Production

Congratulations to Alina LaPotin, Yang Zhong, Lenan Zhang, Lin Zhao, Arny Leroy, Hyunho Kim, Sameer R. Rao for their recent work on Dual-Stage Atmospheric Water Harvesting Device featured on MIT News! This work demonstrated a dual-stage AWH device using commercial zeolite (AQSOA Z01) where the two stages increased the productivity, and the latent heat of condensation was recycled from the top stage to assist in desorption of the bottom stage. This work highlights opportunities for higher capacity and more efficient water production and opens new pathways toward scalable, lower-cost solar-thermal AWH systems.
