Because people spend most of their time indoors, much of their exposure to ozone occurs in
buildings, which are partially protective against outdoor ozone. Measurements in …

As a strong oxidizing gas, ozone can damage the human respiratory tract and
cardiovascular system. Aside from ambient outdoor ozone that enters buildings, indoor …

Germicidal ultraviolet light (GUV) systems are designed to control airborne pathogen
transmission in buildings. However, it is important to acknowledge that certain conditions …

Oxygen vacancy engineering is an efficient strategy to improve the catalytic performance of
nanomaterials. In this work, a highly active Fe-modified manganese oxide (Fe-MnO x) was …

Ozone is a reactive gas that can have negative health effects on human. Building materials
can be significant sinks for indoor ozone, owing to the irreversible heterogeneous reactions …

This study investigated the effectiveness of different polarities of ionizers in inactivating
bioaerosols in a duct flow condition. Three bacteria species—Escherichia coli (E. coli) …

O 3 decomposition catalysts with excellent performance still need to be developed. In this
study, Ag-modified manganese oxides (AgMnO x) were synthesized by a simple co …

In the study, the catalyst precursors of Ce-modified γ-MnO 2 were washed with deionized
water until the pH value of the supernatant was 1, 2, 4 and 7, and the obtained catalysts …

This chapter provides an overview of the types, sources and current techniques for
characterising volatile organic compounds (VOC) in nonindustrial indoor environments. It …

The process of toilet-flushing can generate flushing-associated water droplets which can
potentially expose humans to pathogen-laden aerosols. Very little is known about such …
