Size Effects in Shape Memory Ceramics
(Massachusetts Institute of Technology, 2021-06)
Bulk shape memory ceramics (SMCs) are attractive for their high transformation temperatures and transformation stresses compared to shape memory metals but exhibit transformation-induced cracking due to mismatch stresses ...
Catalytic properties, densification and mechanical properties of nanocrystalline yttria-zirconia-based materials
(Massachusetts Institute of Technology, 2007)
Alumina, titania, ceria and manganese oxide were either coated onto or doped in cubic 7 mol% Y203-ZrO2 (7YZ) nanocrystals to form nanocomposites for methane combustion. These novel catalysts were very active and thermally ...
New methodologies for interconnect reliability assessments of integrated circuits
(Massachusetts Institute of Technology, 2000)
The stringent performance and reliability demands that will accompany the development of next-generation circuits and new metallization technologies will require new and more accurate means of assessing interconnect ...
Exploring kinetics and thermodynamics in fast-ion conductors and hydrogen-storage materials using ab-initio molecular dynamics
(Massachusetts Institute of Technology, 2007)
We investigate the interplay between various kinetic processes and thermodynamic factors in three materials--silver iodide (AgI), cesium hydrogen sulfate (CsHSO4), and sodium alanate (NaAlH4)-using ab-initio molecular ...
Tissue-material interactions : bioadhesion and tissue response
(Massachusetts Institute of Technology, 2009)
Diverse interactions between soft tissues and implanted biomaterials directly influence the success or failure of therapeutic interventions. The nature and extent of these interactions strongly depend on both the tissue ...
First principles study of structure and lithium storage in inorganic nanotubes
(Massachusetts Institute of Technology, 2009)
The exact structure of layered inorganic nanotubes is difficult to determine, but this information is vital to using atomistic calculations to predict nanotube properties. A multi-walled nanotube with a circular cross ...
Integration of pentacene-based thin film transistors via photolithography for low and high voltage applications
(Massachusetts Institute of Technology, 2012)
An organic thin film transistor (OTFT) technology platform has been developed for flexible integrated circuits applications. OTFT performance is tuned by engineering the dielectric constant of the gate insulator and the ...
Applications of powder interlayers for large gap joining
(Massachusetts Institute of Technology, 1997)
Large gap joints are frequently encountered in the manufacturing of massive components as well as in the repairing of damaged parts. Several methods using powder interlayers to produce large clearance transient liquid phase ...
Anisotropic dewetting in ultra-thin single-crystal silicon-on-insulator films
(Massachusetts Institute of Technology, 2008)
The single crystal silicon-on-insulator thin film materials system represents both an ideal model system for the study of anisotropic thin film dewetting as well as a technologically important system for the development ...
Investigation of bone response to implant materials by electron microscopy and computer simulation
(Massachusetts Institute of Technology, 2004)
(cont.) implementation of this scintigraphic method for quantitative studies of osteoblast-mediated mineralization in vitro. A 2-D truss finite element model is used to study the remodeling of trabecular bone. Using strain ...
