Systems with critical functionality and are prone to damage due to excessive stress level from operation conditions and working environment requires health monitoring. Condition or health monitoring involves acquiring data that can be...
The goal of this research is to fabricate, characterize and apply the designed polymer based porous piezoelectric material into practical use. In line with the goal, the research objectives are: Select proper materials that have...
A practical method to utilize carbon nanotubes (CNTs) in structural applications is to fabricate them into buckypapers (BPs), a thin film containing two-dimensional CNT networks, and combine them with a polymer matrix to make BP-polymer ...
Photon upconversion (UC) is a unique process that has garnered increased interest in the past decade as a way to harness lower energy photons and convert them to higher energy for use in a host of applications. In molecular UC, a...
Polymers are essential to modern life. Yet there still remains a wealth of knowledge to discover regarding novel polymeric materials, processing techniques, and applications. The synthesis and application of nanostructured amphiphilic...
Simulation is valuable since it can provide a link between theory and experiment. Whereas, com- puter modeling is based on theory and is limited to simple models, we can explore many physical properties in a parallel way to experiment....
The objectives of this research are to develop lightweight high-performance nanotube composite actuators that can be operated in open air and to study their actuation mechanisms. We successfully demonstrated solid electrolyte-based...
This work implements inverse methods in various polymer characterization problems. In the first topic, a new approach is proposed to infer the comonomer content using Crystaf method considering and quantifying the associated uncertainty....
Co₄Nb₂O₉ is a quasi two dimensional material that has been known to exhibit magnetoelectric behavior with an antiferromagnetic transition (T[subscript N]) at ∼ 27 K. Our findings reveal strong evidence of magnon heat transport below T...
Biological hard materials are a remarkable class of materials combining large volumes of mineral with minute organic components into often complex, hierarchical microstructural arrangements. These intricate microstructures offer ideal...
Ligand passivated nanoparticles have applications in solid-state lighting, plasmonics, and catalysis. At the nanoscale, the properties of these materials can be manipulated by reaction kinetics, allowing for systematic control to achieve...
Carbon nanotubes (CNT) have shown very attractive mechanical properties, compared to current high-performance carbon fiber reinforcements. Recently, continuous CNT yarns (CNTy) have become commercially available and are becoming a...
This dissertation examines the origins of free carrier density in semiconductor nanocrystals and relates these findings to the observed localized surface plasmon resonances (LSPRs). The first chapter introduces some of the most relevant...
