Modeling Conductive Properties Of Highly Aligned Single-Walled Carbon Nanotube And Graphene Thin Films, Mark Joseph Foster

Browse all Theses and Dissertations

Properties of layered material systems have been investigated since the 1940s and are currently very well understood. Classical mechanics combined with the well-developed lamination theory enable the prediction of multi-layered system properties once the properties of its constituents are known. The ability of the lamination theory to predict the conductive properties of multi-layered highly aligned single-walled carbon nanotube (SWCNT) and graphene thin films is investigated. Experimental results showed that the classical lamination theory is not valid in the case of the investigated nanofilm system. Using experimental results, we developed a closed form model using MATLAB which enabled the correct prediction …

Influence Of Build Direction On Interface Regions In Additive Manufacturing Of Multi-Material Refractory Alloys, Cherish Christina Clark Lesko

Browse all Theses and Dissertations

In the pursuit of optimum performance, materials engineering seeks to design the microstructure and thus the properties of a material through the control of the material composition and processing. Functionally graded materials (FGM) are designed to incorporate location-specific material properties through compositional changes within the part. Moving toward location-specific design of material properties requires the ability to produce material gradients in three dimensions which can be accomplished through the use of additive manufacturing (AM). This research examines the composition-process-structure-property relationship of early iteration titanium (Ti) and tantalum (Ta) graded alloys built in a novel laser powder bed fusion (LPBF) process …

Texture Evolution In Materials With Layered Crystal Structures, Vamsi Krishna Vempati Jan 2021

Texture Evolution In Materials With Layered Crystal Structures, Vamsi Krishna Vempati

Browse all Theses and Dissertations

Materials with a layered structure consist of crystalline layers that are bonded to each other with secondary bonds (van der Waals interactions). The bonding between crystalline layers is relatively weak compared to the interatomic bonding within the crystalline layers. This research hypothesizes that under appropriate conditions, such as elevated temperature, the deformation of layered materials occurs like the classic “deck of cards” with no preferred direction of slip on the slip planes. The motivation for this study is from the experimental texture evolution of one such material, Bismuth Telluride ,(Bi2Te3), commonly used materials for thermoelectric applications in the range of …

Enhanced Gamma Band Mutual Information Is Associated With Impaired Consciousness During Temporal Lobe Seizures, Puneet Dheer, Sandipan Pati, Kalyan Kumar Chowdhury, Kaushik Kumar Majumdar Dec 2020

Enhanced Gamma Band Mutual Information Is Associated With Impaired Consciousness During Temporal Lobe Seizures, Puneet Dheer, Sandipan Pati, Kalyan Kumar Chowdhury, Kaushik Kumar Majumdar

Journal Articles

Background: Epileptic seizures are characterized by aberrant synchronization. We hypothesized that higher synchronization across the seizure onset zone (SOZ) channels during a temporal lobe seizure contributes to impaired consciousness. New method: All symmetric bivariate synchronization measures were extended to multivariate measure by a principal component analysis (PCA) based technique. A novel nonparametric method has been proposed to test the statistical significance between increased synchronization across the seizure onset zone (SOZ) channels and reduced consciousness. Results: Increased synchronization in the gamma band towards seizure termination significantly contributes to impaired consciousness (p < 0.1). Synchronization reaches its peak in the extratemporal region (frontal lobe) ahead of the temporal region (p < 0.05). Synchronization is prominent in beta and gamma bands by most methods and it is more in the second half of seizure duration than in the first (p < 0.05). Conclusions: Mutual information is the only synchronization measure out of the six that we studied, whose increase can be associated with the loss of consciousness in a statistically significant way.

Journal of Extension

School-based growing spaces support student engagement in science, technology, engineering, and mathematics (STEM) learning through authentic agricultural pursuits. We conducted a survey of Nebraska schools to characterize existing school-based growing spaces and to identify challenges limiting garden-based STEM learning. Our findings confirm the use of school-based growing spaces for kindergarten through 12th-grade STEM instruction, especially in the sciences. Opportunities for technology and engineering experiences are currently limited, and additional professional development support is needed to broaden garden-based STEM learning efforts. Our findings are relevant to current and future Extension efforts supporting school gardens, especially in rural agricultural communities.

Investigating The Evolution Of Sedimentary Features Near Monopiles, Kate Firth Oct 2020

Investigating The Evolution Of Sedimentary Features Near Monopiles, Kate Firth

The Plymouth Student Scientist

Many of the large windfarms off the coast of the UK are founded on sandbanks and the movement of sediment from around the monopile foundations leave the structures susceptible to severe scour pits and significant scour wake downstream. The removal of sediment not only has a negative impact on the structures but also the cables that run between each turbine. Areas of sediment accretion can cause localised overheating while areas of erosion can cause early fatigue. The paper presents findings of laboratory experiments completed to begin to understand the propagation of the scour wake in unidirectional current flow conditions. It …
