Electrode Effect On Ferroelectricity In Free-Standing Membranes Of Pbzr0.2Ti0.8O3, Qiuchen Wu, Kun Wang, Alyssa Simpson, Yifei Hao, Jia Wang, Dawei Li, Xia Hong
Department of Physics and Astronomy: Faculty Publications
We report the effects of screening capacity, surface roughness, and interfacial epitaxy of the bottom electrodes on the polarization switching, domain wall (DW) roughness, and ferroelectric Curie temperature (TC) of PbZr0.2Ti0.8O3 (PZT)- based free-standing membranes. Singe crystalline 10−50 nm (001) PZT and PZT/La0.67Sr0.33MnO3 (LSMO) membranes are prepared on Au, correlated oxide LSMO, and two-dimensional (2D) semiconductor MoS2 base layers. Switching the polarization of PZT yields nonvolatile current modulation in the MoS2 channel at room temperature, with an on/off ratio of up to 2 × 105 …

Sound Energy Could Change The World, Tyler Bugiel
Sound Energy Could Change The World, Tyler Bugiel
Op-Eds from ENSC230 Energy and the Environment: Economics and Policies
The energy crisis is a problem that has been growing more concerning for many years, and yet there has not seemed to be a good solution to the problem. That being said, I think that there is a solution that has not been explored thoroughly enough, that solution being sound energy. Solar and wind are both energy systems that use natural resources and things that occur on a day to day basis to convert those things into energy, but sound has not been explored as much.

Highly pathogenic avian influenza viruses (HPAIVs) of the A/goose/Guangdong/1/1996 lineage H5 clade 2.3.4.4b continue to have a devastating effect on domestic and wild birds. Full genome sequence analyses using 1369 H5N1 HPAIVs detected in the United States (U.S.) in wild birds, commercial poultry, and backyard flocks from December 2021 to April 2022, showed three phylogenetically distinct H5N1 virus introductions in the U.S. by wild birds. Unreassorted Eurasian genotypes A1 and A2 entered the Northeast Atlantic states, whereas a genetically distinct A3 genotype was detected in Alaska. The A1 genotype spread westward via wild bird migration and reassorted with North American …

Waterfowl infected with avian influenza A viruses (IAVs) shed infectious virus into aquatic environments, providing a mechanism for transmission among waterfowl, while also exposing the entire aquatic ecosystem to the virus. Aquatic invertebrates such as freshwater snails are likely exposed to IAVs in the water column and sediment. Freshwater snails comprise a significant portion of some waterfowl species’ diets, so this trophic interaction may serve as a novel route of IAV transmission. In these experiments, tadpole snails (Physa spp.) were exposed to a low-pathogenicity IAV (H3N8) to determine whether snails can accumulate the virus and, if so, how long virus …
Economic And Environmental Performance Of Integrated Crop-Livestock Systems: Resilience To Uncertainties And An Opportunity For Sustainable Intensification, Maroua Afi
Dissertations and Doctoral Documents, University of Nebraska-Lincoln, 2023–
Integrated crop-livestock systems are promoted as an alternative for sustainable intensification of food production. They have the potential to offer enhanced input efficiency and maintain a diversified livelihood which plays an important role in building resilience of agricultural systems. This work aims to evaluate the technical efficiency of “Integrated Crop-Livestock Systems” (ICLS), “Specialized Livestock Systems” (SLS) and “Specialized Cropping Systems” (SCS) and to identify the determinants behind inefficiencies in these systems. It also aims to assess the resilience against climate variability and market fluctuations. The first chapter provides a comparative analysis and an overview of technical efficiency assessment of farming …
