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 ...
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 ...
Stress evolution during growth and atomic-scale surface structure effects in transition-metal thin films
(Massachusetts Institute of Technology, 2004)
Thin films are defined by an extremely high ratio of the in-plane dimensions to the thickness, resulting in very high surface-to-volume ratios. For this reason, the surface characteristics of a film play an important role ...
Thermodynamic stability and implications of anisotropic boundary particles
(Massachusetts Institute of Technology, 2005)
(cont.) Generally, a boundary is nonplanar in the neighborhood of an attached particle--even when anisotropic interfacial free energies do not produce faceting-and maintains a icKy = 0 while the boundary particles maintain ...
Langasite bulk acoustic wave resonant sensor for high temperature applications
(Massachusetts Institute of Technology, 2005)
(cont.) The self consistent defect model established the defect chemistry of langasite, enabling important parameters describing reduction (Er = 5.70± -0.06eV and 6.57±-0.24eV for acceptor and donor doped langasite ...
Toward commercializable microphase-separating copolymer electrolytes for rechargeable lithium batteries
(Massachusetts Institute of Technology, 2003)
Microphase-separating copolymers have been shown to possess the electrical properties of a polymer liquid and the mechanical properties of a solid. In the past, these materials had to be produced via anionic methods that ...
Supramolecular NanoStamping (SuNS) : fabricating nano/bio devices using DNA as a movable type
(Massachusetts Institute of Technology, 2007)
When a useful device is developed, it always requires a mass-production technique to industrialize it. In the era of nano/biotechnology, the development of printing techniques has not followed the speed of the inventions ...
Adsorption and conformation change of short helical peptides on silica and aluminosilicate surfaces
(Massachusetts Institute of Technology, 2002)
Motivated by the challenges in understanding important features of protein adsorption, the interactions between (-helical peptides and a carefully selected set of model surfaces were studied. The peptide sequences contained ...
