Description
Over the past two decades, the fashion industry has evolved to both create and respond to the consumer's demand for fast fashion, the industry of inexpensive clothing produced at high rates to respond to changing consumer trends. As fast fashion grew in popularity, the new standard of the industry was to create and manufacture every other week, producing continual new trends for a market designed for continual consumption. As the garments being produced were made for short life-spans, textile waste began to grow and the fashion industry was named the second largest pollutant in the world next to oil. Coming out of a market saturated with clothing, a new trend focused around sustainability and reuse has emerged: the resale market. With increased awareness for sustainability, circular fashion business models have emerged from a more linear and disposable supply chain. By focusing on environmental, social, and financial aspects of a supply chain, otherwise known as the triple bottom line, we discuss how second-hand shopping should be managed to satisfy customer shopping expectations.
The creative project of this thesis showcases various wardrobes that have solely been purchased second-hand. The purpose of the creative presentation is to show that no matter one’s style preference, occupation, or age, second hand shopping can appeal to every type of customer. Second hand shopping is not only for “thrifty” millennials, it it for everyone, and can encompass anyone’s clothing needs.

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.

Description
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.

Description
Current Li-ion battery technologies are limited by the low capacities of theelectrode materials and require developments to meet stringent performance demands for
future energy storage devices. Electrode materials that alloy with Li, such as Si, are one
of the most promising alternatives for Li-ion battery anodes due to their high capacities.
Tetrel (Si, Ge, Sn) clathrates are a class of host-guest crystalline structures in which
Tetrel elements form a cage framework and encapsulate metal guest atoms. These
structures can form with defects such as framework/guest atom substitutions and
vacancies which result in a wide design space for tuning materials properties. The goal of
this work is to establish structure property relationships within the context of Li-ion
battery anode applications. The type I Ba 8 Al y Ge 46-y clathrates are investigated for their
electrochemical reactions with Li and show high capacities indicative of alloying
reactions. DFT calculations show that Li insertion into the framework vacancies is
favorable, but the migration barriers are too high for room temperature diffusion. Then,
guest free type I clathrates are investigated for their Li and Na migration barriers. The
results show that Li migration in the clathrate frameworks have low energy barriers (0.1-
0.4 eV) which suggest the possibility for room temperature diffusion. Then, the guest
free, type II Si clathrate (Na 1 Si 136 ) is synthesized and reversible Li insertion into the type
II Si clathrate structure is demonstrated. Based on the reasonable capacity (230 mAh/g),
low reaction voltage (0.30 V) and low volume expansion (0.21 %), the Si clathrate could
be a promising insertion anode for Li-ion batteries. Next, synchrotron X-ray
measurements and pair distribution function (PDF) analysis are used to investigate the
lithiation pathways of Ba 8 Ge 43 , Ba 8 Al 16 Ge 30 , Ba 8 Ga 15 Sn 31 and Na 0.3 Si 136 . The results
show that the Ba-clathrates undergo amorphous phase transformations which is distinct
from their elemental analogues (Ge, Sn) which feature crystalline lithiation pathways.
Based on the high capacities and solid-solution reaction mechanism, guest-filled
clathrates could be promising precursors to form alloying anodes with novel
electrochemical properties. Finally, several high temperature (300-550 °C)
electrochemical synthesis methods for Na-Si and Na-Ge clathrates are demonstrated in a
cell using a Na β’’-alumina solid electrolyte.

Nike, the largest athletic apparel company in the world, has a very complex wide-reaching supply chain. As pioneers of outsourcing production and products, they have dealt with many challenges and problems since their beginning in 1964. As Nike has faced their controversial history of labor strikes, protests, boycotts, and much more, they began to restructure their business model and supply chain practices. Following this came audits, minimum age requirements, factory condition monitoring, and public disclosures of locations. With these new initiatives and growth in Nike’s supply chain, an overarching analysis of Ports of Lading, Shipment Origins, Ports of Unlading, Shippers/Suppliers, and Carriers can give a glimpse into the world-wide network of their apparel. Finally, through my data analysis and secondary source research, I will explain how Nike's supply chain emerged, adjusted, and changed given different textile regulatory environments over the years.
