Real Time Measurement of Agglomerated or Aggregated Airborne Nanoparticles Released From a Manufacturing Process and Their Transport Characteristics

认识到纳米颗粒的产生可能对人类和环境构成风险，这笔赠款将允许对从制造过程释放到工作场所和环境的空气中的纳米颗粒进行实时测量。此外，该奖项将允许该团队使用实验和数值模拟来了解空气中纳米颗粒的传输特性。该团队开发的一种新仪器--通用纳米颗粒分析仪将用于在线测量颗粒形态。结果将得到颗粒形态对纳米颗粒命运和传输的影响，这些结果将在估计大气寿命、确定环境命运和纳米颗粒的最终生物利用度方面发挥重要作用。这里开发的形态测量方法将在排放监测和风险评估中得到广泛应用。结果将由国际和平研究所在研究生课程中传播，并通过国家科学基金会的纳米技术及其对社会的影响的公共教育计划来传播。苏黎世理工大学将成为该项目的国际合作伙伴。

Recognizing that nanoparticle generation may pose a risk to humans and environment, this grant will allow for the real-time measurement of airborne nanoparticles released from a manufacturing process to the workplace and environment. Additionally, the award will allow the team to use experiments and numerical modeling understand the transport characteristics of airborne nanoparticles. A new instrument developed by the team, the universal nanoparticle analyzer, will be used for online measurement of particle morphology.Results will be obtained on the effects of the particle morphology on nanoparticle fate and transport, which play an important role in estimation of the atmospheric lifetimes, determination of environmental fate and eventual bioavailability of nanoparticles. The method for morphology measurement developed here will find broad use for emission monitoring and risk assessment. Results will be disseminated by the PI in graduate courses and through NSF programs for public education of nanotechnology and its impact on society. ETH Zurich will be an international partner for this project.
