The linear and nonlinear rheology of multiscale complex fluids
(Massachusetts Institute of Technology, 2014)
The microstructures of many complex fluids are typically characterized by a broad distribution of internal length scales. Examples of such multiscale materials include physically and chemically cross-linked gels, emulsions, ...
Electric field based fabrication methods for multi-scale structured surfaces
(Massachusetts Institute of Technology, 2014)
Control of micro/nano scale surface structures and properties is crucial to developing novel functional materials. From an engineering point of view, the development of scalable and economical micro/nano-fabrication methods ...
A deviational Monte Carlo formulation of ab initio phonon transport and its application to the study of kinetic effects in graphene ribbons
(Massachusetts Institute of Technology, 2014)
We present a deviational Monte Carlo method for solving the Boltzmann equation for phonon transport subject to the linearized ab initio 3-phonon scattering operator. Phonon dispersion relations and transition rates are ...
Fundamental studies of perovskite related oxide thin films for oxygen electrocatalysis at intermediate temperatures
(Massachusetts Institute of Technology, 2014)
Discovering highly active and stable catalysts for electrochemical energy conversion and storage is essential to envision a new generation of renewable energy applications. Mixed ionic and electronic conductors (MIECs) ...
The economics of future membrane desalination processes and applications
(Massachusetts Institute of Technology, 2014)
Seawater desalination, the desalination of waters flowing back from hydraulic fracturing processes and brackish water desalination constitute important desalination applications. These have a combined market size in excess ...
Elongated fascicle-inspired 3D tissues consisting of high-density, aligned, optogenetically excitable muscle tissue using sacrificial outer molding
(Massachusetts Institute of Technology, 2014)
The majority of muscles, nerves, and tendons are composed of fiber-like fascicle morphology. Each fascicle has a) elongated cells highly aligned with the length of the construct, b) a high volumetric cell density, and c) ...
Advanced materials for enhanced condensation heat transfer
(Massachusetts Institute of Technology, 2014)
This thesis investigates the use of three classes advanced materials for promoting dropwise condensation: 1. robust hydrophobic functionalizations 2. superhydrophobic textures 3. lubricant-imbibed textures We first define ...
Exploring heat transfer at the atomistic level for thermal energy conversion and management
(Massachusetts Institute of Technology, 2014)
Heat transfer at the scales of atoms plays an important role in many applications such as thermoelectric energy conversion and thermal management of microelectronic devices. While nanoengineering offers unique opportunities ...
Incompressible journal bearings with combined hydrostatic-hydrodynamic action.
(Massachusetts Institute of Technology, 1965)
Large eddy simulations of premixed turbulent flame dynamics : combustion modeling, validation and analysis
(Massachusetts Institute of Technology, 2014)
High efficiency, low emissions and stable operation over a wide range of conditions are some of the key requirements of modem-day combustors. To achieve these objectives, lean premixed flames are generally preferred as ...
