In modern civilizations, developing policies that impact the environment and human health requires scientific studies that provide a complete understanding of the variables that define and affect the quality of the air we breathe, water we drink, and species we eat. In this research, HQP will focus on improving indoor air quality with novel nano and QMs. Newly developed nano and QMs will find use in numerous applications including mineral paints, coatings, inks, indoor electronics, and more, which could be sold as 'ecofriendly' consumer items. These materials contain transition metal oxides that are active in the dark and under indoor lighting and could convert volatile organic compounds (VOCs) in indoor air to more hazardous chemicals. Little is known about the chemical composition, residence period, and chemical reactivity of these particles in indoor air and restricted spaces. The HQP will investigate nano and QMs chemical composition, phase, and size in indoor VOCs absorption, degradation rates via photochemical pathways, and reactive oxygen species generation efficiency under ambient atmospheric, geochemical, and physiological circumstances.
