Templated self-assembly of nanoporous alumina : pore formation and ordering mechanisms, methodologies, and applications
(Massachusetts Institute of Technology, 2005)
Porous anodic aluminum oxide (AAO), also known as porous alumina, is a self-ordered nanostructured material well-suited for use in electronic, magnetic, optical and biological applications due to its small pore size (4-200nm) ...
Scanning probe microscopy with inherent disturbance suppression using micromechanical systems
(Massachusetts Institute of Technology, 2005)
All scanning probe microscopes (SPMs) are affected by disturbances, or mechanical noise, in their environments which can limit their imaging resolution. This thesis introduces a general approach for suppressing out-of-plane ...
Packaging for a drug delivery microelectromechanical system
(Massachusetts Institute of Technology, 2005)
Local drug delivery is a fast expanding field, and has been a center of attention for researchers in medicine in the last decade. Its advantages over systemic drug delivery are clear in cancer therapy, with localized tumors. ...
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 ...
Improving maintenance work flow processes in a volatile assembly factory environment : maintenance people and processes, spares inventory, and equipment reliability
(Massachusetts Institute of Technology, 2005)
Many manufacturing companies face significant challenges in maintaining their factory equipment in a cost efficient manner so as to provide reliable production capacity. CEI (Consumer Electronics, Inc., a pseudonym for an ...
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 ...
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 ...
Composite gelatin delivery system for bone regeneration
(Massachusetts Institute of Technology, 2005)
In this thesis, the chemical/mechanical properties and biocompatibility of gelatin were investigated to produce a gelatin scaffold for the release of bone morphogenetic proteins (BMPs) from composite particles. This delivery ...
Determination of special boundary coordination at quadruple nodes using EBSD
(Massachusetts Institute of Technology, 2005)
Grain boundaries are known to play an important role in materials properties including corrosion and cracking resistance. Some grain boundaries are resistant to corrosion and cracking and are known as "special" boundaries. ...
Characterization of polystyrene-block-poly (acrylic acid) micelles
(Massachusetts Institute of Technology, 2005)
Several parameters that affect the formation, size and spatial distribution of micelles of poly(styrene-block-acrylic acid) (PS-b-PAA) in organic solvents or assembled on solid substrates have been investigated. The micelles ...
