The broader impact/commercial potential of this Small Business Innovation Research (SBIR) Phase II project is addressing the growing societal need for indoor air purification, as indoor air quality (IAQ) directly affects human health, productivity, cognitive function, and quality-of-life. Awareness of the long-term consequences of poor IAQ has recently witnessed an increase due to research results, improvements in monitoring and sensing technology, public awareness campaigns by organizations such as the American Lung Association, World Health Organization, and Environmental Protection Agency, and, most recently, the COVID-19 pandemic. Finding sustainable, economical, and effective solutions to the problem of poor IAQ will greatly benefit public health and wellbeing and will help curtail the spread of pathogens, minimizing the need for social distancing. This project will develop a new system air purification, addressing viruses, harmful chemicals, odors, and ultrafine particulates.This Small Business Innovation Research (SBIR) Phase II project aims to scale up the production methodology and coating process of novel catalytic materials. The materials are 3D nanostructured porous powders that are designed at multiple length scales to achieve enhanced catalytic activity, stability, and longevity, while reducing costs and utilizing raw materials in an environmentally responsible manner. The system uses a synthetic approach based on self-organization of nanoscale building blocks and wet chemistry tools in order to assemble finely structured coatings for integration in air-purification units. This project focuses on expanding it to production scale, wherein achieving control over the composition, structure, porosity, and placement of nanoparticles on a production scale is challenging. The materials platform development will include adaptation to high-throughput instrumentation and scale-up of the material production and coating process to pilot production. In the process, this project will develop tools and guidelines for manufacturing hierarchically-structured functional materials more generally.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

这项小型企业创新研究（SBIR）第二阶段项目的更广泛的影响/商业潜力正在解决室内空气净化的不断增长的需求，因为室内空气质量（IAQ）直接影响人类健康，生产力，认知功能和生活质量。由于研究结果的改善，美国肺部协会，世界卫生组织和环境保护署等组织的公众意识运动的改善，对贫困IAQ差的长期后果的认识最近见证了增加的增长，以及诸如Covid-19的Pandemic。找到可持续，经济和有效的解决方案，解决贫困IAQ问题将极大地使公共卫生和福祉受益，并有助于减少病原体的传播，从而最大程度地减少社会疏远的需求。 该项目将开发一种新的系统空气净化，以解决病毒，有害化学物质，气味和超细颗粒。此小型企业创新研究（SBIR）II期项目旨在扩大新型催化材料的生产方法和涂层过程。这些材料是3D纳米结构的多孔粉末，以多长度设计以实现增强的催化活性，稳定性和寿命，同时降低成本并以环境负责的方式利用原材料。该系统采用基于纳米级构建块和湿化学工具的自我组织的合成方法，以组装精美的结构化涂层以在空气纯化单元中进行集成。该项目的重点是将其扩展到生产规模，在其中，可以控制纳米颗粒在生产规模上的组成，结构，孔隙率和放置的控制。 材料平台的开发将包括适应高通量仪器，并扩大材料生产和涂料工艺以进行试点生产。在此过程中，该项目将更广泛地制定制造层次结构的功能材料的工具和准则。该奖项反映了NSF的法定任务，并使用基金会的知识分子优点和更广泛的影响审查标准，被认为值得通过评估来提供支持。
