Critical thickness in silicone thermosets
(Massachusetts Institute of Technology, 2005)
Critical thickness effects are utilized to achieve high fracture toughness in brittle polymers. The postulate of critical thickness, which is: "Macroscopically brittle polymers deform in a ductile fashion below a critical ...
Scanned pulsed laser annealing of Cu thin films
(Massachusetts Institute of Technology, 2005)
As the microelectronics industry has moved to Cu as the conductor material, there has been much research into microstructure control in Cu thin films, primarily because grain sizes affect resistivity. Also with Cu-based ...
Towards in-situ device fabrication : electrostatic lithography and nanowire field effect devices
(Massachusetts Institute of Technology, 2005)
Electron beams were used to deposit fine line-width charge in electret materials. The electrets were exposed to charged or polarizable nanoparticle precursors. These nanoparticles decorate the charge pattern. Electret ...
The design, synthesis and properties of pressure-processable biodegradable block copolymers
(Massachusetts Institute of Technology, 2005)
In this thesis, biodegradable block copolyesters were specifically designed and synthesized for their susceptibility to pressure-induced mixing. These baroplastic materials are capable of being processed and molded through ...
Nano-contact printing of DNA monolayers
(Massachusetts Institute of Technology, 2005)
Technology today is directed towards building smaller devices. To accommodate this development, printing methods are needed. Some printing methods that are used include lithography, micro-contact printing, and inkjet ...
Gradient-Index (GRIN) lenses by Slurry-based Three-Dimensional Printing (S-3DP)
(Massachusetts Institute of Technology, 2005)
GRIN lenses with vertical index variation and radial index variation have been successfully fabricated using S-3DPTM. Two silica-based material systems, A1203-SiO₂ and BaO-SiO₂, have been studied and used for the fabrication ...
Deformation induced molecular behavior of Cis 1,4-polyisoprene and its nanocomposites monitored by solid-state NMR
(Massachusetts Institute of Technology, 2005)
Proton spin lattice (T1) relaxation time constants were used to monitor changes in the molecular motion and architecture of polyisoprene, polyisoprene-clay composites and polyhedral oligomeric silsesquioxane (POSS) ...
Implementation of a manufacturing process platform
(Massachusetts Institute of Technology, 2005)
As companies grow and innovate, they offer an increasing number of products. Product proliferation must be managed through a product development process, which is supported by key competencies of the company in the form ...
Product design for supply chain : quantifying the costs of complexity in Hewlett-Packard's retail desktop PC business
(Massachusetts Institute of Technology, 2005)
Over the past several years, Hewlett-Packard Company's North America Consumer Computing (NACC) division has faced pressures to increase retail product variety in response to growing customer demand. As they pursue incremental ...
Measurement and control of brake pedal feel quality in automobile manufacturing
(Massachusetts Institute of Technology, 2005)
Customer perception of brake pedal feel quality, as related to the perception of the brake pedal feeling soft or mushy, depends on both the customer's subjective judgment of quality and the actual build quality of the brake ...
