Linking structure to fragility in bulk metallic glass-forming liquids

Creator:: Wei, Shuai, Stolpe, Moritz, Gross, Oliver, Evenson, Zach, Gallino, Isabella, Hembree, William, Bednarcik, Jozef, Kruzic, Jamie J., and Busch, Ralf
Abstract:: Using in-situ synchrotron X-ray scattering, we show that the structural evolution of various bulk metallic glass-forming liquids can be quantitatively connected to their viscosity behavior in the supercooled liquid near T[subscript g]. The structural signature of fragility is identified as the temperature dependence of local dilatation on distinct key atomic...

Quasicrystal Formation, Structure and Indentation Behaviors in Pure Tantalum

Creator:: Wang, Zhengming
Abstract:: Spontaneous quasicrystal (QC) formation has not been observed in pure metals either in computation or in experiments (excluding epitaxial growth of thin atomic layers on a QC template). In this thesis work, dodecagonal QC (DDQC) grains are first discovered to spontaneously form during thermal devitrification of pure tantalum (Ta) metallic...

Ignition of Fuel Beds by Firebrands

Creator:: Bean, Derek R.
Abstract:: The severity of wildfires around the globe is increasing. At the same time, urban development is expanding outward into areas where severe fires occur. There is an increased risk of home loss to fires in areas where severe fires and urban expansion meet. Ignition of homes or nearby fuel is...

Light soaking in metal-halide perovskites

Creator:: Watts, C. Lowell
Abstract:: Despite climate change requiring the cutback of fossil fuel consumption, the world continues to increase its energy demands each year. To meet the ambitious goals outlined during the Paris Agreement in 2015, which set a goal to limit global warming to 1.5°C [1], changes in energy production methods are necessary....

Multi-objective Resilience Optimization of Interdependent Critical Infrastructure Networks

Creator:: Tiong, Achara
Abstract:: Critical Infrastructures (CIs) such as energy, water supply, telecommunications, and transportation are highly vulnerable to cascading failures due to their interdependent operations. A resilient network is crucial to withstand the impact of functionality loss in disruptive events. This research evaluates network expansion as a proactive resilience strategy in which new...

Temperature Evolution of Spark Kernels in Quiescent and Cross-flow Conditions

Creator:: Okhovat, Sebastian
Abstract:: Numerous physical and chemical processes are required for successful ignition of a flammable mixture, many of which have been well characterized. However, one aspect of the ignition process that has received limited consideration is understanding the temperature of the spark kernel. A spark kernel is the volume of heated gas...

High Temperature Electrical Properties of Ceria-Based Ceramics for Use as Electrodes in Magnetohydrodynamic Power Generators

Creator:: Bowen, Michael S.
Abstract:: Determining the electrical properties of ceria-based materials is important for their use as electrodes in hot-wall magnetohydrodynamic (MHD) power generators with wall temperatures greater than 1500 ̊C. The electrical conductivity of a material can be used in models for predicting the performance of generator designs. More specifically, the temperature dependent...

Potential Additive-Manufacturing of Ablative Thermal Protection Systems

Creator:: Hazell, Kenya K.
Abstract:: Electrodeposition is a versatile polymer deposition technique to create nano-microscale materials using an electrical field generated from a charged droplet of solution and a grounded collector. Electrospinning or electrospraying can occur during electrodeposition, leading to the creation of nanofibers or bead-like materials depending on the process parameters. Photopolymerization of the...

Probabilistic Wind Power Forecasting for Hybrid Systems

Creator:: Irmas, Cameron
Abstract:: Wind power forecasting provides valuable insights for demand response, energy market operation, and plant control optimization. Probabilistic approaches—which capture uncertainty in these complex systems by representing predictions as probability distributions—represent a growing area of research in wind energy science. However, their applications for wind-based hybrid systems, particularly those focused on...

Assessing Mass Diffusion Modeling in Premixed Flames

Creator:: Fillo, Aaron J.
Abstract:: Implementing multicomponent diffusion in numerical combustion studies is computationally expensive due to the challenges involved in computing diffusion coefficients. As a result, mixture-averaged diffusion treatments or simpler methods are used to avoid these costs. However, the accuracy and appropriateness of the mixture-averaged diffusion model has not been verified for three-dimensional...
