EEC-0813631Luster-teasleyBRIGE awards maintain global competitiveness by increasing the diversity of ENG researchers, who are initiating research programs early in their careers. BRIGE awards further the broaden participation of engineering researchers by increasing the number of engineering graduates, by improving the representation of women and minorities in engineering, and by understanding how to improve recruitment and retention of engineering students.This BRIGE award will investigate controlled-release polymers for subsurface soil remediation. The PI plans to utilize chemical oxidation to inject highly reactive liquids or gases into a contaminated zone. The chemical oxidants rapidly react to oxidize and breakdown subsurface contaminants to less toxic byproducts. The research will investigate a new method of chemical oxidant delivery that is expected to provide significant advantages over methods currently in use. The investigator will test a novel delivery system that uses biodegradable polymers to encapsulate a solid oxidant. The basic concept is to encapsulate an oxidant in biodegradable polymers in the form of solid pellets that slowly release the oxidant after application. Like an "environmental pill", the oxidants can be placed subsurface to slowly deliver treatment to the environment. This new method effectively extends the ability to provide chemical oxidation treatment for remediation in a fashion similar to drug formulations delivered using biodegradable medical implants which provide controlled and extended release of their active componentsMore than 200,000 sites in the United States require some form of environmental remediation. Of these sites, the most difficult to remediate are locations in which contaminated subsurface soils and groundwater are present. This research will benefit society as a whole by providing a safer method to treat subsurface contamination and a new method to protect and treat water and soil. This research will serve as an example for using biomaterials to improve water and soil treatment practices in environmental engineering. Additionally, this project will provide research opportunities to minority undergraduate and graduate students from the underrepresented populations served by North Carolina A&T State University. The PI will also develop an environmental engineering module for this research, environmental remediation, and novel uses for biodegradable polymers for an on-line education program.This BRIGE grant will broaden the participation of and increase opportunities for all engineers including those from groups underrepresented in the engineering disciplines. This BRIGE grant will also encourage the PI to become actively and competitively engaged in research as an independent investigator.

EEC-0813631 Luster-teasleyBRIGE奖项通过增加ENG研究人员的多样性来保持全球竞争力，这些研究人员在职业生涯的早期就开始了研究项目。 BRIGE奖项通过增加工程专业毕业生的数量，提高女性和少数民族在工程领域的代表性，以及了解如何提高工程专业学生的招聘和保留率，进一步扩大了工程研究人员的参与。该BRIGE奖项将研究用于地下土壤修复的控释聚合物。PI计划利用化学氧化将高活性液体或气体注入污染区。 化学氧化剂迅速反应，将地下污染物氧化和分解为毒性较小的副产物。 该研究将调查一种新的化学氧化剂输送方法，预计将提供比目前使用的方法显着的优势。研究人员将测试一种新型的输送系统，该系统使用可生物降解的聚合物来封装固体氧化剂。 基本概念是将氧化剂以固体颗粒的形式包封在可生物降解的聚合物中，在应用后缓慢释放氧化剂。就像“环境药丸”一样，氧化剂可以放置在地下，慢慢地将治疗效果传递到环境中。 这种新方法有效地扩展了提供化学氧化处理的能力，以类似于使用可生物降解的医疗植入物递送的药物制剂的方式进行补救，该植入物提供其活性成分的受控和延长释放。在这些地点中，最难补救的是存在受污染的地下土壤和地下水的地点。这项研究将通过提供一种更安全的地下污染处理方法和一种保护和处理水和土壤的新方法来造福整个社会。这项研究将作为一个例子，使用生物材料，以改善水和土壤处理的做法，在环境工程。 此外，该项目将为来自北卡罗来纳州AT州立大学服务的代表性不足的人口的少数民族本科生和研究生提供研究机会。& PI还将为这项研究开发一个环境工程模块，环境修复，以及可生物降解聚合物的在线教育计划的新用途。BRIGE赠款将扩大所有工程师的参与并增加他们的机会，包括那些来自工程学科代表性不足的群体的工程师。 该BRIGE赠款还将鼓励PI作为独立调查员积极参与研究。
