CBET - 1737620 (Fini, Elham).This is a green engineering project that targets the enablement of the production of a bio-nanocomposite. The bio-nanocomposite is to be composed of montmorillonite clay and a bio-modifier made from swine manure. Use of such bio-based modifier can help reduce worldwide reliance on shrinking petroleum reserves while reducing CO2 emissions associated with the manufacture of petroleum-based products and the uncontrolled bio-waste decay in landfills and open lagoons.The hypothesis to be tested is that that montmorillonite clay can be exfoliated using an amide-enriched bio-modifier made from swine manure to produce organo-clay containing individual silica nano-platelets. While the exfoliated clay can be used in multiple applications, this project aims to evaluate sustainability and technical feasibility of producing bio-based nano composite for use as construction materials. Accordingly, a secondary hypothesis is that introduction of the aforementioned bio-based nanocomposite into construction materials for outdoor applications such as roofing, sealing, building facades, roads and drive ways will have enhanced resistance to oxidative aging due to clay nano-particles playing as air barrier as well as carrier for certain bio-molecules with anti-aging properties. Accordingly, the project will examine environmental aspects of such outdoor applications along with technical feasibility. To do so, special attention will be given to study quality and quantity of the emissions during processing of bio-based nano composites as well as leachates during their application. Therefore, resulting material will be evaluated in terms of both associated thermo-mechanical properties and environmental aspects.

CBET - 1737620（Fini，Elham）。这是一个绿色工程项目，旨在实现生物纳米复合材料的生产。该生物纳米复合材料由蒙脱石粘土和猪粪制成的生物改性剂组成。使用这种生物基改性剂可以帮助减少全球对日益减少的石油储量的依赖，同时减少与石油基产品制造相关的二氧化碳排放以及垃圾填埋场和开放泻湖中不受控制的生物废物腐烂。要测试的假设是蒙脱石粘土可以使用由猪粪制成的富含酰胺的生物改性剂进行剥离，以生产含有单独二氧化硅纳米片的有机粘土。虽然剥离粘土可用于多种应用，但该项目旨在评估生产用作建筑材料的生物基纳米复合材料的可持续性和技术可行性。因此，第二个假设是，将上述生物基纳米复合材料引入户外应用的建筑材料中，例如屋顶、密封、建筑外墙、道路和车道，由于粘土纳米颗粒充当空气，因此将具有增强的抗氧化老化能力某些具有抗衰老特性的生物分子的屏障和载体。因此，该项目将审查此类户外应用的环境方面以及技术可行性。为此，将特别关注研究生物基纳米复合材料加工过程中排放物以及应用过程中渗滤液的质量和数量。因此，将根据相关的热机械性能和环境方面对所得材料进行评估。
