Oxide Thermoelectrics: The Role of Crystal Structure on Thermopower in Strongly Correlated Spinels
(2012-08-10)
This dissertation reports on the synthesis, structural and thermal characterization and electrical and thermal transport properties of a variety of strongly correlated spinels. General structure property relationships for ...
Soft Active Materials for Actuation, Sensing, and Electronics
(2012-07-24)
Future generations of robots, electronics, and assistive medical devices will include systems that are soft and elastically deformable, allowing them to adapt their morphology in unstructured environments. This will require ...
Bioinspired, Dynamic, Structured Surfaces for Biofilm Prevention
(2012-11-14)
Bacteria primarily exist in robust, surface-associated communities known as biofilms, ubiquitous in both natural and anthropogenic environments. Mature biofilms resist a wide range of biocidal treatments and pose persistent ...
Studies on Synthesis, Structural and Electrical Properties of Complex Oxide Thin Films: Ba1-xSrxTiO3 and La2-xSrxNiO4
(2012-07-27)
High performance miniaturized passives are of great importance for advanced nanoelectronic packages for several applications including efficient power delivery. Low cost thin film capacitors fabricated directly on package ...
Energetic Beam Processing of Silicon to Engineer Optoelectronically Active Defects
(2012-07-26)
This thesis explores ways to use ion implantation and nanosecond pulsed laser melting, both energetic beam techniques, to engineer defects in silicon. These defects are chosen to facilitate the use of silicon in optoelectronic ...
Electrode-Electrolyte Interfaces in Solid Polymer Lithium Batteries
(2012-09-24)
This thesis studies the performance of solid polymer lithium batteries from room temperature to elevated temperatures using mainly electrochemical techniques, with emphasis on the bulk properties of the polymer electrolyte ...
Wetting in Color
(2012-11-06)
Colorimetric litmus tests such as pH paper have enjoyed wide commercial success due to their inexpensive production and exceptional ease of use. However, expansion of colorimetry to new sensing paradigms is challenging ...
Synthesis and Applications of Non-spherical Dimer Colloids
(2012-10-18)
Colloids are promising building blocks in material synthesis because of their controllability of size and surface properties. The synthesis of chemically and/or geometrically anisotropic colloidal particles has received ...
Self-Organization of Bioinspired Fibrous Surfaces
(2012-09-18)
Nature uses fibrous surfaces for a wide range of functions such as sensing, adhesion, structural color, and self-cleaning. However, little is known about how fiber properties enable them to self-organize into diverse and ...
