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 ...
Novel potentials for the simulation of polyethylene and other polymeric systems
(Massachusetts Institute of Technology, 2005)
Throughout the history of science, people have been developing models to explain reality. The advent of computer technology has made it possible to devise and implement incredibly complicated numerical models in a relatively ...
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 ...
Energy absorption in Ni-Mn-Ga/ polymer composites
(Massachusetts Institute of Technology, 2006)
In recent years Ni-Mn-Ga has attracted considerable attention as a new kind of actuator material. Off-stoichiometric single crystals of Ni2MnGa can regularly exhibit 6% strain in tetragonal martensites and orthorhombic ...
Tunable micro-cavities in photonic band-gap yarns and optical fibers
(Massachusetts Institute of Technology, 2006)
The vision behind this work is the fabrication of high performance innovative fiber-based optical components over kilometer length-scales. The optical properties of these fibers derive from their multilayer dielectric ...
Advanced engineered substrates for the integration of lattice-mismatched materials with silicon
(Massachusetts Institute of Technology, 2006)
The dramatic advances in Si/SiO2-based microelectronic processing witnessed over the past several decades can largely be attributed to relatively material-independent device scaling. However, with physical and economic ...
Anisotropic and tunable characteristics of the colloidal behavior of metal oxide surfaces
(Massachusetts Institute of Technology, 2006)
The electroosmotic behavior of the rutile polymorph of titanium dioxide was explored as a function of crystallographic orientation. Atomic force microscopy (AFM) was employed to make high-resolution force spectroscopy ...
Water modeling the solid oxide membrane electrolysis with rotating cathode process
(Massachusetts Institute of Technology, 2004)
The Kroll process for refining titanium is an expensive batch process which produces a final product that still requires intensive post processing to create usable titanium. A new process, Solid Oxide Membrane Electrolysis ...
