Evaporation from nanopores : probing interfacial transport
(Massachusetts Institute of Technology, 2018)
Evaporation, a commonly found phenomenon in nature, is widely used in thermal management, water purification, and steam generation as it takes advantage of the enthalpy of vaporization. Despite being extensively studied ...
Molecular and active interfaces : controlling the adhesion of low surface tension fluids and solid microparticles
(Massachusetts Institute of Technology, 2018)
ABSTRACT This thesis will investigate several approaches that utilize interfacial engineering to control the wetting of low surface tension liquids and adhesion of solid microparticles on surfaces. While approaches to repel ...
Engineered interfaces controlling the nucleation and flowability of complex fluids
(Massachusetts Institute of Technology, 2018)
In recent years, surface engineering has enabled remarkable advances in various fields of fluid mechanics. High mobility of water and even low surface tension fluids was demonstrated using surfaces with engineered chemistry ...
Mechanistic study of slug formation and evolution in high-viscosity-liquid/High-density-gas multiphase flows in channels/pipes
(Massachusetts Institute of Technology, 2018)
Rapidly rising global energy demand coupled with dwindling conventional oil resources has pushed unconventional oil, such as heavy oil, to become one of the most important future energy resources. However, design and ...
Automation and scalability of in vivo neuroscience
(Massachusetts Institute of Technology, 2018)
Many in vivo neuroscience techniques are limited in terms of scale and suffer from inconsistencies because of the reliance on human operators for critical tasks. Ideally, automation would yield repeatable and reliable ...
Design and fabrication of a flexible membrane ultrasound transducer
(Massachusetts Institute of Technology, 2018)
Wearable ultrasound sensing could enable novel medical diagnostics by facilitating continuous, real-time, and direct measurement of physiological phenomena, such as blood pressure. Currently, ultrasound is not used in ...
Thermal transport at the nanoscale : from fourier diffusion to phonon hydrodynamics
(Massachusetts Institute of Technology, 2018)
From the global pursuit of clean and efficient sources of energy to the challenges presented by the high power densities in the semiconductor industry to the problem of decoherence in quantum systems, thermal processes are ...
Hairy interfaces
(Massachusetts Institute of Technology, 2018)
Textured surfaces are known to play an important role in water-repellency and uptake for a number of creatures. While the influence of chemistry and surface roughness on the wettability of surfaces has been studied ...
Experimental and ab initio studies of oxide interfaces for photoelectrochemistry
(Massachusetts Institute of Technology, 2018)
The threats posed by anthropogenic climate change have spurred a research thrust towards renewable, carbon-free sources of energy. Photoelectrochemical (PEC) approaches are particularly attractive, combining energy capture ...
Airborne monitoring system for in-season agriculture : operational considerations and image processing for wide-area sensing
(Massachusetts Institute of Technology, 2018)
Remote sensing, in particular multispectral imagery, can measure crop health and detect in-season disturbances such as pests and diseases before they are visible to the naked eye, but it is inaccessible to small-plot ...
