The purpose of this thesis research project is to explore blockchain technology and its present and future applications within supply chain management. Emerging blockchain technologies, both public and private, are already showing great promise for a number of applications in and outside supply chain management. Our sole focus is to understand the fundamentals of blockchain, smart contracts, current applications in supply chain, and the future possibilities for blockchain to shape global supply chains. Many have theorized about how private blockchains can be implemented and used; however, there is little research to date that has collected and explored the actual use cases in industry today. The mission of this research paper is to separate theory from the current state of the technology and provide a clearer understanding of where the technology is headed in the near future. We aim to produce a work that will provide a comprehensive description and commentary on current use cases for the education of students and industry professionals alike. With any new technological developments, terminology and technicalities can be paralyzing, and this is particularly true for blockchain technology. For this project, our goal was to create a document that cuts through the complexities and allows a non-technical audience to gain a strong foundational understanding of blockchain's potential and current limitations within supply chains. Provided this, some highly technical concepts and implementation details will not be explored due to the complexity and minimal understanding even amongst industry experts. As future supply chain professionals, we are motivated to further our understanding of blockchain technologies and the potential for this technology to shape the future of supply chain management.

This thesis investigates the potential of life cycle analysis for more sustainable sourcing strategies in organizations. Using the example of the College of Lake County (CLC) in Illinois, I study how life-cycle analysis can help to improve the procurement of products and services in higher education. Currently, CLC's purchasing team does not understand how sourcing affects operational and environmental performance. In addition, CLC's purchasing team does not communicate effectively with other departments from a product utilization standpoint. The objective of this research is to analyze CLC's current product procurement process and to assess the feasibility of implementing life cycle analysis tools. Further, I evaluate different life cycle analysis tools and provide recommendations to CLC about the applicability of these tools so that they may be implemented into the university in the future. First, I find that both the procurement and IT department at CLC are not familiar with life-cycle analysis tools and hence, do not know about the life cycle of their processes and services. Second, I identify professional life cycle analysis tools relevant for CLC. Two software options, GaBi and SimaPro, are discussed. Finally, I suggest six steps for a successful implementation of life cycle analysis at CLC: (1) form an interdisciplinary team, (2) analyze demand and collect additional data, (3) conduct a product life cycle analysis using a software tool, (4) define which products to analyze further, (5) conduct life cycle costing analysis with the same software tool, and (6) utilize these results for decisions and delegation of responsibility.

The following report addresses sustainable supply chain management (SSCM) and its application in the fashion industry. The purpose is to draw conclusions on why companies implement sustainability into their processes, and how these sustainable monitoring practices contribute to operational, competitive and financial advantages. This report contains various methods of analysis. Research derived from numerous scholarly articles on measurement methods, theories and governance structures will be discussed to develop a background on the current status of SSCM in the fashion industry, including the notable strengths and weaknesses. To understand the depth of practices involved in managing a sustainable supply chain, four leading companies within the industry will be analyzed using their annual sustainability reports. Based on this analysis, it can be concluded that sustainable practices are abundantly present in today's leading fashion companies, each having different mindsets motivating their sustainable actions. With this conclusion, it's also important to acknowledge that there's far more progress to be made in terms of sustainable development on a company and industry level, in order to make a lasting impact.

Lithium ion batteries are quintessential components of modern life. They are used to power smart devices — phones, tablets, laptops, and are rapidly becoming major elements in the automotive industry. Demand projections for lithium are skyrocketing with production struggling to keep up pace. This drive is due mostly to the rapid adoption of electric vehicles; sales of electric vehicles in 2020 are more than double what they were only a year prior. With such staggering growth it is important to understand how lithium is sourced and what that means for the environment. Will production even be capable of meeting the demand as more industries make use of this valuable element? How will the environmental impact of lithium affect growth? This thesis attempts to answer these questions as the world looks to a decade of rapid growth for lithium ion batteries.

The Russian invasion of Ukraine began in February 2022, and has caused a ripple effect of global supply disruptions. The United States, Canada, EU and other allies have responded to the Russian invasion of Ukraine by sanctioning imports from Russia in an attempt to isolate their economy. However, some countries that have not placed trade sanctions on Russia are taking advantage of the opportunity to import from Russia. By integrating import data from Panjiva into a geospatial mapping tool, ArcGIS, global trade patterns can be visualized to understand how global trade is impacted, the effectiveness of Western sanctions on Russia, and potential substitution effects on trade flows from one country to another. First, six key commodities and three countries were identified based on preliminary data analysis. After further analysis, it can be concluded that the Russian sanctions were not effective at isolating their economy for two reasons: certain commodities are critical to our modern lifestyles and some countries took advantage of Western trade sanctions on Russia and increased global trade. In an attempt to diversify their supply, many firms sourced from countries other than Russia, but oftentimes commodities are still sourced from Russia. Lack of supply chain visibility prevents business leaders from making the most efficient supply networks that are in alignment with government regulations.

Lithium conducting garnets in the family of Li7La3Zr2O12 (LLZO) are promising lithium conductors for solid-state batteries, due to their high ionic conductivity, thermal stability, and electrochemical stability with metallic lithium. Despite these advantages, LLZO requires a large energy input to synthesize and process. Generally, LLZO is synthesized using solid-state reaction (SSR) from oxide precursors, requiring high reaction temperatures (900-1000 °C) and producing powder with large particle sizes, necessitating high energy milling to improve sinterability. In this dissertation, two classes of advanced synthesis methods – sol-gel polymer-combustion and molten salt synthesis (MSS) – are employed to obtain LLZO submicron powders at lower temperatures. In the first case, nanopowders of LLZO are obtained in a few hours at 700 °C via a novel polymer combustion process, which can be sintered to dense electrolytes possessing ionic conductivity up to 0.67 mS cm-1 at room temperature. However, the limited throughput of this combustion process motivated the use of molten salt synthesis, wherein a salt mixture is used as a high temperature solvent, allowing faster interdiffusion of atomic species than solid-state reactions. A eutectic mixture of LiCl-KCl allows formation of submicrometer undoped, Al-doped, Ga-doped, and Ta-doped LLZO at 900 °C in 4 h, with total ionic conductivities between 0.23-0.46 mS cm-1. By using a highly basic molten salt medium, Ta-doped LLZO (LLZTO) can be obtained at temperatures as low as 550 °C, with an ionic conductivity of 0.61 mS cm-1. The formation temperature can be further reduced by using Ta-doped, La-excess pyrochlore-type lanthanum zirconate (La2Zr2O7, LZO) as a quasi-single-source precursor, which convert to LLZTO as low as 400 °C upon addition of a Li-source. Further, doped pyrochlores can be blended with a Li-source and directly sintered to a relative density up to 94.7% with high conductivity (0.53 mS cm-1). Finally, a propensity for compositional variation in LLZTO powders and sintered ceramics was observed and for the first time explored in detail. By comparing LLZTO obtained from combustion, MSS, and SSR, a correlation between increased elemental inhomogeneity and reduced ionic conductivity is observed. Implications for garnet-based solid-state batteries and strategies to mitigate elemental inhomogeneity are discussed.
