Dan recently developed a vertically translating and angularly deflecting MEMS stage without any solid-solid contact to overcome friction-induced failure. The stage is actuated by electrowetting (image copyright AIP Publishing 2016).
Dan and others in the DRL explored the current state of the field of nanoengineered surfaces for enhanced phase-change heat transfer and proposed promising future directions (image copyright Nature Publishing Group 2016).
Dan, Ari, and the DRL won the Green Labs $1k seed funding and $5k Innovation Award to found the MIT Lab Energy Assessment Center, which will provide energy assessments to labs on campus using a wireless network of sensors.
In Dan's recently published work, monolayer graphene coatings are shown to promote dropwise condensation and provide a robust alternative to fluorocarbon monolayer coatings (image copyright ACS Publications 2015).
Dan grows these nanowires as part of a study on jumping droplets. When functionalized with a hydrophobic coating, the high roughness and low solid fraction of the nanowires are favorable for jumping. Scale bar is 200 nm.
Dan has worked with the DRL since June 2012. The DRL investigates heat and mass transport processes at the micro- and nano-scales to discover new functionalities and realize new technologies for energy, thermal management, water desalination, and biological systems.
Electrowetting MEMS Stage
(16 December 2016) Dan's research developing a MEMS stage to translate and tilt without solid-solid connections using electrowetting for actuation has been published in Applied Physics Letters.
Review on Phase Change Heat Transfer
(6 December 2016) Dan and coauthors in the DRL had a review paper on nanoengineered material selection and design for phase change heat transfer enhancement published in Nature Reviews Materials.
Electrowetting for Jumping Droplets
(1 February 2016) Dan's collaboration with Dr. Andrea Cavalli from the University of Tewnte on electrically induced drop detachment and ejection has produced a publication in Physics of Fluids.
