Solution-gated graphene transistors for chemical and biological sensing applications
(Massachusetts Institute of Technology, 2013)
Various fabrication processes were developed in order to make graphene-based chemical and biological sensors on different substrates. Single-layer graphene is grown by chemical vapor deposition and then transferred to ...
Modeling trabecular microstructure evolution via genetic algorithm
(Massachusetts Institute of Technology, 2014)
Connecting structure to properties, and optimizing properties by controlling structure is one of the fundamental goals of materials science and engineering. No where is this connection more apparent than with biomaterials, ...
Thin film BCZT in a capacitive thermo-electric converter
(Massachusetts Institute of Technology, 2016)
Thin film BCZT was processed, optimized, and analyzed from powder to ceramic to film for use in a capacitive thermos-electric converter. The idea of using a temperature dependent dielectric to turn heat into electricity ...
Scaling the rock : a micromechanical model for the elastic properties of hydrated cement pastes
(Massachusetts Institute of Technology, 2011)
Cement is the most widely produced material worldwide. However, the understanding on how its nanoscale composition affect its microscale mechanical properties is limited. In this thesis, a micromechanical model for the ...
An experimental study on the structure-property relationship of composite fluid electrodes for use in high energy density semi-solid flow cells
(Massachusetts Institute of Technology, 2012)
A novel electrochemical energy storage device, the semi-solid flow cell (SSFC), has recently been demonstrated. The device features a complex fluid composite as its anode and cathode. Both electrodes incorporate particles ...
Phononic metamaterials based on complex geometries : "a new kind of metamaterial"
