Stannate Nanomaterials For Sustainable Fire Safety: Processing, Characterization And Application, Gregory M. Wrobel Mr.

Doctoral Dissertations

Statistically, accidental residential and vehicle fires cause ~3000 fatalities, and ~$10 billion in damages per year in the United States. To reduce the hazard, many flammable products are protected with bromated flame-retardants. However, studies have proven their use to pose major environmental and health hazards. A recent EPA mandate calls to phase out common formulations by 2014. To fill the void, incorporation of replacements is critical, however few offer such efficient and versatile protection. This dissertation intends to provide solutions through research and development of non-toxic zinc and calcium hydroxystannate (ZHS, CHS) nanoparticle based flame retardants for common textiles.

Scaling Of Crop Diversity And Optimal Allocation Of Foodshed Infrastructure, Michael Chang

Biology ETDs

Food hubs are organizations that manage the aggregation and distribution of local products, and are a small, but growing means to satisfy high demand for diverse, healthy diets. However, economic barriers inhibit small producers and distributors from developing mainstream, local consumer alternatives to industrial-scale products. To build foodshed, distribution hubs could help overcome these challenges by reducing costs through shared refrigeration, processing, and transportation infrastructure. However, there is no theory to help plan them. I present and test theory to allocate foodshed infrastructure based on insight by Dunn, et al. (2011) that Shannon diversity measured relative to a whole set …
