M13 bacteriophage-enabled assembly of nanocomposites : synthesis and application in energy conversion devices
(Massachusetts Institute of Technology, 2013)Lack of energy supply and non-uniform distribution of traditional energy sources, such as coal, oil, and natural gas, have brought up tremendous social issues. To solve these issues, highly efficient energy conversion ... -
M13 virus/single-walled carbon nanotubes as a materials platform for energy devices and biomedical applications
(Massachusetts Institute of Technology, 2011)Making nanocomposites from combinations of materials each with their own unique functional advantage can often solve issues that cannot be addressed when utilizing only one type of materials. Therefore, controlling ... -
The machine casting of high temperature semi-solid metals.
(Massachusetts Institute of Technology, 1975) -
A machine learning approach to crystal structure prediction
(Massachusetts Institute of Technology, 2007)This thesis develops a machine learning framework for predicting crystal structure and applies it to binary metallic alloys. As computational materials science turns a promising eye towards design, routine encounters with ... -
Machine learning transferable physics-based force fields using graph convolutional neural networks
(Massachusetts Institute of Technology, 2020)Molecular dynamics and Monte Carlo methods allow the properties of a system to be determined from its potential energy surface (PES). In the domain of crystalline materials, the PES is needed for electronic structure ... -

Magnetic behavior of 360° domain walls in patterned magnetic thin films
(Massachusetts Institute of Technology, 2012)360° transverse domain walls (360DWs), which form readily from transverse 180° domain walls (180DWs) of opposite sense, demonstrate qualitatively distinct behaviors from their constituent 180DWs and are therefore of interest ... -
Magnetic domain walls driven by interfacial phenomena
(Massachusetts Institute of Technology, 2014)A domain wall in a ferromagnetic material is a boundary between differently magnetized regions, and its motion provides a convenient scheme to control the magnetization state of the material. Domain walls can be confined ... -
Magnetic domain walls for on-chip transport and detection of superparamagnetic beads
(Massachusetts Institute of Technology, 2014)Surface-functionalized superparamagnetic (SPM) microbeads are of great interest in biomedical research and diagnostic device engineering for tagging, manipulating, and detecting chemical and biological species in a fluid ... -
Magnetic microparticle trapping and mechanical excitation using domain walls in magnetic microstructures
(Massachusetts Institute of Technology, 2011)We examined the feasibility of using the resonant frequency of magnetic bead-domain wall (DW) couples in a host fluid to measure particle size. Nickel-Iron (Permalloy) rings, made using electron beam lithography, served ... -
Magnetic nanostructures patterned by block copolymer lithography
(Massachusetts Institute of Technology, 2008)The aim of this research was twofold: understanding the methods of patterning magnetic films using self-assembled block copolymer masks and examining the magnetic reversal mechanisms of as deposited and patterned magnetic ... -
Magnetic properties of block-copolymer fabricated cobalt nanodots and nanowires at elevated temperatures
(Massachusetts Institute of Technology, 2015)Patterned media on the nanometer scale are useful for electrical, optic, and magnetic applications such as memory storage. Using block copolymer fabrication methods, 60nm diameter cobalt nanodots and 37nm wide cobalt ... -
Magnetic properties of lithographically patterned thin film magnetic elements for magnetic random access memory applications
(Massachusetts Institute of Technology, 2003)Interference lithography, together with ion beam etching or lift-off processes, has been utilized to produce large area periodic rectangular patterns. Single layer Co, NiFe, and multilayer Co/Cu/NiFe pseudo spin valve films ... -
Magnetic properties of small multi-layered rings
(Massachusetts Institute of Technology, 2007)Thin film rings can be an alternative geometry of magnetic memory cells, in which data bits are stored by the chirality of the flux-closed or 'vortex' state of the ring. The absence of the stray field in the vortex state ... -
Magnetic thin films For spintronic memory
(Massachusetts Institute of Technology, 2018)Domain walls are regions of spatially non-uniform magnetizations in magnetic materials. They form the boundaries between two or more uniformly magnetized regions called domains. Skyrmions are circular magnetic domains with ... -
Magneto-mechanical properties and applications of Ni-Mn-Ga ferromagnetic shape memory alloy
(Massachusetts Institute of Technology, 2000)Ferromagnetic shape memory alloys (FSMA's) have shown large strains under magnetic field as magnetic variants in the rnartensite rearrange to accommodate the applied field. The theoretical maximum field-induced strain is ... -
Magneto-optical and multiferroic oxide thin films, integrated nonreciprocal photonic devices and multiferroic memory devices
(Massachusetts Institute of Technology, 2015)Complex oxide thin films offer unique functionalities which can potentially extend the utility of current storage, processing and optical isolator technologies. In this thesis, we present three categories of studies on ...
