Room temperature multiferroic properties of single-phase (Bi₀.₉La₀.₁)FeO₃-Ba(Fe₀.₅Nb₀.₅)O₃ solid solution ceramics

Creator:: Paik, Hanjong, Hwang, Hosung, No, Kwangsoo, Kwon, Seunghwa, and Cann, David P.
Abstract:: The crystal structure and multiferroic properties of single-phase (Bi₀.₉La₀.₁)FeO₃–Ba(Fe₀.₅Nb₀.₅)O₃ ceramics were investigated. The rhombohedral-type structure of 1.0(Bi₀.₉La₀.₁)FeO₃) was transformed to a monoclinic-type structure for the 0.5(Bi₀.₉La₀.₁)FeO₃–0.5Ba(Fe₀.₅Nb₀.₅)O₃) composition. It shows the coexistence of ferroelectricity and magnetism at room temperature, represented by a high dielectric constant with ferroelectric hysteresis and clear magnetic...

Informatics and Standards for Nanomedicine Technology

Creator:: Thomas, Dennis G., Klaessig, Fred, Harper, Stacey L., Fritts, Martin, Hoover, Mark D., Gaheen, Sharon, Stokes, Todd H., Reznik-Zellen, Rebecca, Freund, Elaine T., Klemm, Juli D., Paik, David S., and Baker, Nathan A.
Abstract:: There are several issues to be addressed concerning the management and effective use of information (or data), generated from nanotechnology studies in biomedical research and medicine. These data are large in volume, diverse in content, and are beset with gaps and ambiguities in the description and characterization of nanomaterials. In...

ISA-TAB-Nano: A Specification for Sharing Nanomaterial Research Data in Spreadsheet-based Format

Creator:: Thomas, Dennis G., Gaheen, Sharon, Harper, Stacey L., Fritts, Martin, Klaessig, Fred, Hahn-Dantona, Elizabeth, Paik, David, Pan, Sue, Stafford, Grace A., Freund, Elaine T., Klemm, Juli D., and Baker, Nathan A.
Abstract:: Background and motivation: The high-throughput genomics communities have been successfully using standardized spreadsheet-based formats to capture and share data within labs and among public repositories. The nanomedicine community has yet to adopt similar standards to share the diverse and multi-dimensional types of data (including metadata) pertaining to the description and...

Unconditional estimating equation approaches for missing data

Creator:: Lu, Lin
Abstract:: Missing data can lead to biased and inefficient estimation if the missing mechanism is not taken into account in the analysis. In this dissertation we propose two estimators that, under fairly general conditions, are asymptotically unbiased. The first proposed estimator assume the data are missing at random (MAR) and does...

Defect Mechanisms in Bismuth-based Perovskites

Creator:: Kumar, Nitish
Abstract:: The aim of this research is to develop a fundamental understanding of the dominant defect species and the relevant defect equilibrium conditions for bismuth-containing perovskites to help guide the development of these materials for emerging applications. This is of paramount importance for many demanding applications, because ultimately the defect equilibria...

Comparative phenotypic studies on vibrios of environmental origin that resemble human clinical isolates

Creator:: Greenwood, John David
Abstract:: A comparative investigation of the phenotypic properties of environmental and clinical strains of the lactose-positive human pathogen, Vibrio vulnificus, revealed that they are indistinguishable in traits commonly used for identification in clinical and public health laboratories. It has also been confirmed that there are other strains of undefined Vibrio spp.,...

Multilayer ceramic capacitors based on relaxor BaTiO₃-Bi(Zn₁/₂Ti₁/₂)O₃ for temperature stable and high energy density capacitor applications

Creator:: Kumar, Nitish, Ionin, Aleksey, Ansell, Troy, Kwon, Seongtae, Hackenberger, Wesley, and Cann, David
Abstract:: The need for miniaturization without compromising cost and performance continues to motivate research in advanced capacitor devices. In this report, multilayer ceramic capacitors based on relaxor BaTiO₃-Bi(Zn₁/₂Ti₁/₂)O₃ (BT-BZT) were fabricated and characterized. In bulk ceramic embodiments, BT-BZT has been shown to exhibit relative permittivities greater than 1000, high resistivities (ρ > 1...

Molecular genetics and enzymology of secondary metabolite biosynthesis. I, Isolation of natural product biosynthesis gene clusters from symbiotic marine organisms. II, Enzymology of blasticidin S biosynthesis

Creator:: Grochowski, Laura L.
Abstract:: Molecular genetic and enzymological techniques have been employed to study secondary metabolite biosynthesis. These investigations have focused on two projects: the cloning and heterologous expression of biosynthetic gene clusters from unculturable marine organisms and the characterization of individual enzymes involved in the biosynthesis of the antifungal agent blasticidin S. The...

Automated Zebrafish Chorion Removal and Single Embryo Placement: Optimizing Throughput of Zebrafish Developmental Toxicity Screens

Creator:: Mandrell, David, Moore, Aaron, Jephson, Caleb, Sarker, Mushfiqur R., Lang, Christopher, Truong, Lisa, Simonich, Michael T., and Tanguay, Robert L.
Abstract:: The potential of the developing zebrafish model for toxicology and drug discovery is limited by inefficient approaches to manipulating and chemically exposing zebrafish embryos—namely, manual placement of embryos into 96- or 384-well plates and exposure of embryos while still in the chorion, a barrier of poorly characterized permeability enclosing the...

Development of perovskite thin films for use in piezoelectric based microelectromechanical systems

Creator:: Shelton, Christopher T.
Abstract:: The lead-zirconate-titanate (PZT) solid solution system is currently the workhorse of piezoelectric-based microelectromechanical systems (MEMS) research. Among bulk materials it is known to be one of the strongest piezoelectrics, with extremely high piezoelectric coefficients and electro-mechanical coupling factors. Reproducing these exceptional qualities in thin film form, however, requires precise tuning...
