This EArly Grant for Exploratory Research (EAGER) award will develop a strategy of making the concrete more environmentally friendly by using it as adsorbent to remove Nitrogen Dioxide (NO2), therefore offsetting the NO2 emissions originating from cement production and various other sources. NO2 emissions can cause various environmental and health problems. They contribute to formation of acid rain, atmospheric particles and various other toxic substances resulting in health problems, visibility reduction, eutrification and global warming. One of the most prominent results of NO2 emissions is formation of ground level ozone, which is produced in the reaction of NO2 with volatile organic compounds (VOCs) in the presence of sunlight. When formed, it causes adverse effects such as damage to lung tissue and reduction in lung function. The strategy of using both fresh and aged concrete for NO2 removal offers a significant potential to transform the way the waste concrete is disposed of and recycled. It also brings together such disciplines as structural materials, materials engineering, surface science, environmental chemistry and atmospheric science in an innovative and synergetic manner.

这项早期的探索性研究赠款（渴望）奖将制定一种策略，通过将其用作消除二氧化氮（NO2）的吸附剂来使混凝土更加环保，从而抵消源自水泥产量和其他各种来源的NO2排放。 NO2排放会导致各种环境和健康问题。它们有助于形成酸雨，大气颗粒和各种其他有毒物质，从而导致健康问题，可见性降低，富裕和全球变暖。 NO2排放最突出的结果之一是地面臭氧的形成，该臭氧是在阳光下与挥发性有机化合物（VOC）的NO2反应中产生的。形成时，会引起不良反应，例如对肺组织的损害和肺功能降低。使用新鲜和老化混凝土进行NO2去除的策略为改变废物混凝土的处理方式和回收方式提供了重要的潜力。它还以创新和协同的方式汇集了结构材料，材料工程，表面科学，环境化学和大气科学等学科。
