This award is funded under the American Recovery and Reinvestment Act of 2009 (Public Law 111-5).This Small Business Technology Transfer (STTR) Phase I project is focused on the development of a new technology for reducing the human health risks associated with mercury over the life-cycle of fluorescent lamps. Fluorescent lamps can break and release their internal inventory of mercury, which is a known neurotoxicant, environmental pollutant, and developmental toxicant of special concern for children and women of child-bearing age. Aspen Sciences is teaming with Brown University and ARCH Venture Partners to develop nano-selenium-based products to react with and capture mercury vapor during fluorescent lamp shipping, use, collection, and recycling. The research focuses on: (i) cost-effective nano-selenium synthesis, (ii) design and testing of reactive barriers as box or bag safety liners, (iii) study of reaction rates and sorbent color change for mercury detection, and (iv) sorbent stability during storage use and disposal.The broader impacts of this research are to ensure consumer and worker safety in the large and rapidly growing market for linear and compact fluorescent lamps. Lamps broken at home or during shipping release elemental mercury vapor in the immediate vicinity of adults and children. Approximately 80% of inhaled mercury vapor is physiologically absorbed in the lung and is able to cross the blood-brain barrier to cause neurological disorders and developmental impairment. Aspen's new sorbent can capture mercury vapor at ultra-high capacity and reduce human exposure in the $7 billion annual worldwide fluorescent lamp market, as well as remove current psychological and safety barriers to the more widespread adoption of energy-saving fluorescent technologies.

该奖项是根据2009年《美国复苏和再投资法案》(公法111-5)资助的。这个小型企业技术转让(STTR)第一阶段项目的重点是开发一种新技术，以减少荧光灯生命周期中与汞相关的人体健康风险。荧光灯可以破坏和释放汞的内部库存，汞是一种已知的神经毒物、环境污染物和发育毒物，对育龄儿童和妇女特别关注。Aspen Sciences正在与布朗大学和ARCH Venture Partners合作开发基于纳米硒的产品，以在荧光灯的运输、使用、收集和回收过程中与汞蒸汽反应并捕获汞蒸气。这项研究的重点是：(I)高性价比的纳米硒合成，(Ii)作为盒子或袋子安全衬里的反应性屏障的设计和测试，(Iii)汞检测的反应速率和吸着剂颜色变化的研究，以及(Iv)吸着剂在储存使用和处置过程中的稳定性。这项研究的更广泛影响是确保线性和紧凑型荧光灯巨大且快速增长的市场中的消费者和工人的安全。在家中或在运输过程中损坏的灯具会在成人和儿童附近释放出元素汞蒸气。大约80%吸入的汞蒸气在生理上被肺吸收，并能够越过血脑屏障，导致神经障碍和发育障碍。Aspen的新型吸收剂可以以超高容量捕获汞蒸气，减少人类在全球每年70亿美元的荧光灯市场中的暴露，并消除目前更广泛采用节能荧光技术的心理和安全障碍。
