Shape memory ceramics in small volumes
(Massachusetts Institute of Technology, 2016)
Shape memory ceramics rely on martensitic transformations which are similar to those found in metallic shape memory materials, but ceramics offer several advantages over metals such as higher operating temperatures and ...
Toward efficient and stable quantum dot solar cells : design and characterization
(Massachusetts Institute of Technology, 2016)
This thesis focuses on the optical and electronic properties of lead sulfide (PbS) quantum dots (QDs) for the development of QD solar cells. Near-infrared active PbS QDs composed of earth-abundant elements have emerged as ...
Local exposure and efficacy of a reservoir-based drug delivery device
(Massachusetts Institute of Technology, 2012)
Prognoses for primary or metastatic brain tumor patients have been poor, despite developments in treatment over the last twenty years. 14,000 people die each year from glioblastoma multiforme (GBM). 200,000 new cases of ...
Templated self-assembly for complex pattern fabrication
(Massachusetts Institute of Technology, 2014)
The long-term goal of my Ph.D. study has been controlling the self-assembly of various materials using state-of-the-art nanofabrication techniques. Electron-beam lithography has been used for decades to generate nanoscale ...
Interactions of environmentally-responsive nanoparticles with synthetic and biological membranes
(Massachusetts Institute of Technology, 2014)
Nanoparticles (NPs) have recently emerged as a versatile new materials platform for biomedical applications. By tuning their surface functionality, NPs can be engineered to resemble proteins in terms of size, shape, and ...
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"
(Massachusetts Institute of Technology, 2014)
Facing the growing challenges of energy, environment, security and disease treatment, the demand for novel materials are growing. While the material centric approach have resulted in development of new materials for advanced ...
Synthesis of III-V nitride nanowires with controlled structure, morphology, and composition
(Massachusetts Institute of Technology, 2014)
The III-V nitride materials system offers tunable electronic and optical properties that can be tailored for specific electronic and optoelectronic applications by varying the (In,Ga,Al)N alloy composition. While nitride ...
Computational modeling and design of multilayer corrosion coatings for galvanic protection of steel
(Massachusetts Institute of Technology, 2016)
Steels represent an economically vital class of alloys for use in structural applications, due to low cost and high strength and toughness, but often suffer from high susceptibility to corrosion in relevant environments. ...
Helium behavior at fcc-bcc semicoherent interfaces: trapping, clustering, nucleation, and growth of cavities
(Massachusetts Institute of Technology, 2013)
He implanted into metals precipitates into nanoscale bubbles that grow into voids, degrading the properties of engineering alloys in nuclear energy applications. In this thesis, multi-scale modeling techniques and neutron ...
