Controlling structure across length scales with directed assembly of colloidal nanoparticles
(Massachusetts Institute of Technology, 2020)
One of the promises of nanotechnology is the ability to create a bulk, designer material with its structure programmed at each length scale using deterministic control over the placement of each nanoscale component. ...
Convection and segregation phenomena in low Prandtl number melt growth systems : a quantitative experimental and theoretical approach
(Massachusetts Institute of Technology, 1977)
Experimental and computational study of electromagnetically driven flow due to the passage of a current between two electrodes
(Massachusetts Institute of Technology, 1987)
Block copolymer self-assembly and templating strategies
(Massachusetts Institute of Technology, 2016)
Block copolymers microphase separate to form periodic patterns with period of a few nm and above without the need for lithographic guidance. These self-assembled nanostructures have a variety of bulk geometries (alternating ...
Multi-redox active polyanionic cathodes for alkali-ion batteries
(Massachusetts Institute of Technology, 2016)
In order for alkali-ion batteries to gain widespread adoption as the energy storage technology of choice for transportation and grid applications, their energy must be improved. One key step towards this necessary improvement ...
Enhancing stability of powder-route nanocrystalline tungsten-titanium via alloy thermodynamics
(Massachusetts Institute of Technology, 2013)
Improvement in material properties as a result of grain size refinement to the nanoscale is often limited by an inherent tendency of these nanostructured materials to coarsen especially at the high temperatures required ...
Enhancing quantum-dot luminescence in visible and infrared light emitting devices
(Massachusetts Institute of Technology, 2016)
We investigate how the external quantum efficiency (EQE) of colloidal quantum-dot light emitting devices (QD-LEDs) can be enhanced by addressing in situ QD photoluminescence (PL) quenching mechanisms occurring with and ...
Nanoscale quantification of stress and strain in III-V semiconducting nanostructures
(Massachusetts Institute of Technology, 2015)
III-V semiconducting nanostructures present a promising platform for the realization of advanced optoelectronic devices due to their superior intrinsic materials properties including direct band gap energies that span the ...
Phase transformations in layered electrode materials for sodium ion batteries
(Massachusetts Institute of Technology, 2017)
In this thesis, I investigate sodium ion intercalation in layered electrode materials for sodium ion batteries. Layered metal oxides have been at the forefront of rechargeable lithium ion battery technology for decades, ...
Chemomechanics at cell-cell and cell-matrix interfaces critical to angiogenesis
(Massachusetts Institute of Technology, 2014)
The ability to characterize and control cellular responses in vitro has far reaching implications for basic science and applied medical research. For well over 125 years, researchers have studied the behavior of biological ...
