Filtration and Measurement of Nanoaerosol Particles

清洁的空气是人类生活的重要资源。然而，人口增长、人类活动增强以及工业生产的迅速扩张，导致世界各地对清洁空气的需求前所未有。世界卫生组织2013年的报告显示，每年有200多万人过早死亡是室内和室外空气污染造成的。在所有的空气污染物中，悬浮在空气中的纳米颗粒，被称为纳米气溶胶，被证明是对健康产生不利影响的主要原因。它们还与太阳辐射相互作用，对全球气候变化和极端天气产生负面影响。从空气中去除这些空气传播的纳米颗粒，在它们的来源和环境空气中是非常重要的。

Clean air is a vital resource for human life. However, population growth, enhanced human activities, and the rapid expansion in industrial production have led to unprecedented demand on clean air all over the world. The 2013 report of the World Health Organization has shown that over 2 million premature deaths each year are attributed to indoor and outdoor air pollution. Among all air pollutants, nanosized particles suspended in the air, which are referred to as nanoaerosol, are proved to be the major cause of adverse health effects. They also negatively impact global climate change and extreme weather by interacting with solar radiation. It is of great importance to remove these airborne nanoparticles from the air, at their sources and from the ambient air.
