The Development Of High-Performance Protonic Ceramic Conducting Membranes By Interfacial Engineering, Jun Gao

All Dissertations

Protonic ceramic conductors are the key component in a wide range of protonic ceramic electrochemical devices. Such as protonic ceramic fuel cells, electrolysers, sensors, and hydrogen pumps. The widely studied protonic ceramic conductors are perovskite-structure oxides with high proton conductivity and chemical stability at high temperatures. However, the performance of perovskite-based protonic ceramic conductors dropped rapidly at low temperatures due to the blocking effect of grain boundary. Different from the blocking effect in perovskite membranes, the interface works as an alternative pathway for proton transport in nanostructured simple oxide systems, relying on the chemisorbed and physiosorbed water on the interface. …

Tuning The Structures Of Magnetic Nanoparticles And Thermoresponsive Polymers Towards Magneto-Thermoresponsive Particles, Zichun Yan

All Dissertations

Metal substituted ferrite nanoparticles (MxFe3-xO4, M = Mn, Co, Ni, or Zn) have been synthesized and applied for a variety of biomedical applications, including magnetic hyperthermia treatment, drug delivery, and tunable MRI contrast agents. To better understand the structure-property relationship of such materials, nonstoichiometric manganese ferrite was computationally modeled with density functional theory (DFT). Detailed XRD and HRTEM analysis suggest that substitution-induced crystalline defects cause a discrepancy between the computational results and the experimental results. To improve the control of the size, and composition of the ferrite nanoparticles, a seed-mediated drip synthesis method and post-synthesis oxidation method were developed. Manganese-cobalt …

The Postmodern Legal Ordering Of The Economy, Ioannis Kampourakis

Indiana Journal of Global Legal Studies

This article purports to show how the postmodern · tenets of particularity, reflexivity, decentralization, and pluralism map on to current legal forms and structures of market regulation. This is the case in the regulatory paradigm of shaping markets ''from within," the aspiration of which is to embed public and social values in the operations of private corporate actors, while expanding private corporate actors' regulatory authority and scope of self-governance. As the state attempts to harness the regulatory potential of the social sphere to impose sanctions for corporate misconduct, the role of the law becomes to facilitate the permeability of private …

'Peace Throughout The Oceans And Seas Of The World': British Maritime Strategic Thought And World Order, 1892-1919, Louis Halewood

School of Law, Humanities and Social Sciences

Prior to 1914, British strategic thinkers considered the question of how to maintain British world power in the twentieth century. They developed visions of co-operation at sea between not only Britain and the Dominions, but also other states in the international system. During the First World War, these ideas merged with plans for the League of Nations, which British policymakers envisaged as a tool for enforcing peace through the use of sea power. This article explores these ideas, providing a different interpretation of the origins of the League, and the maritime strategic thought of key individuals including Halford Mackinder.

Lightfastness Of Water-Based Inks Vs. Latex Water-Based Inks, David Lopez Lopez

Theses

This study focused on the lightfastness properties of non-latex water-based inkjet inks and latex inkjet inks for conventional process colors, i.e., cyan, magenta, yellow, and black. Lightfastness is defined as the property of ink that describes the degree of resistance to fading when exposed to light. Lightfastness varies among inks based on their formulation. The degradation of inks caused by light happens when the light is absorbed by the pigments and reacts with the pigments and molecules in the printed substrate. This research evaluated the lightfastness degree of water-based inkjet inks vs. latex inkjet inks. The experiment used printed samples …

On Aqueducts And Anxiety: Water Infrastructure, Ruination, And A Region-Scaled Anthropocene Imaginary, Sayd Randle

Research Collection College of Integrative Studies

This paper explores popular expectations for and meanings of the U.S. West's environmental future, as articulated through recent artistic representations of the Los Angeles's expansive water provision network. Weaving together material from participant observation and readings of creative works, I show how infrastructural imagery is used to index anxieties about a future of water scarcity. Presenting familiar, currently functional water infrastructures as ruins-in-the-making, these artists use the physical stuff of water provision networks to advance critiques of longstanding modes of development and the material basis of urban-rural relations in the U.S. West. Doing so, these imagined ruins draw the global-scale …

Effect Of Ultrasound Pressure On The Distribution Of Bovine Serum Albumin Delivered By Focused Ultrasound-Mediated Blood-Brain Barrier Opening In Cleared Mouse Brains, Yajie Liu

McKelvey School of Engineering Graduate Student Theses & Dissertations

Most common diagnosis and therapeutic methods have low effectiveness when used on brain diseases. The key obstacle is that the blood-brain barrier (BBB) prevents most drugs from entering the brain. Some strategies have been developed to improve the efficiency of drug delivery crossing BBB. Among all these strategies, focused ultrasound-mediated BBB opening (FUS-BBB Opening) stands out since it is noninvasive and can be located to the target area. Detailed studies are required on the distribution of drugs delivered by FUS-BBB opening and the effects of FUS parameters on the distribution. This thesis proposes a pipeline involving tissue clearing and lightsheet …

New Infeed Correction Methods For Distance Protection In Distribution Systems, Fahd Hariri, Mariesa Crow

Electrical and Computer Engineering Faculty Research & Creative Works

The reliability and security of power systems may be jeopardized by the increase in the amounts of renewable generation and the uncertainties produced by these devices. In particular, the protection schemes of traditional power systems have been challenged by the integration of distributed generation (DG) resources. Distance relays (DRs), which have been mainly employed to protect transmission systems, are increasingly proposed as one of the solutions to protect distribution systems with a heavy penetration of DGs. However, conventional distance protection faces several drawbacks that might lead to maloperation. One of those challenges is the "infeed effect", which causes the impedance …
