Article
The elusive sources of air pollution have hampered effective control across all sectors, with long-term consequences for the greenhouse effect and human health. Multiple monitoring systems have been highly desired for locating the sources. However, when faced with extensive sources, diverse air environments and meteorological conditions, the low sp...
Article
Ambient particulate matter (PM) poses severe environmental health risks to the public globally, and efficient filtration technologies are urgently needed for air ventilation. In this contribution, to overcome the efficiency-resistance trade-off for fibrous filtration, we introduced an electrostatic polydopamine-interface-mediated (e-PIM) filter uti...
Chapter
Indoor air cleaning has been proved to be an efficient way to reduce indoor harmful VOCs. Many advanced technologies have been studied for the quick and economical removal of VOCs from indoor air. This chapter introduced photocatalytic oxidation (PCO) and room-temperature thermal catalytic oxidation (TCO). The principle of PCO was introduced, and t...

Particulate matter (PM) poses a severe health threat to the public, and fibrous filtration is a powerful method for efficient PM removal. Arming the fibers with electrostatic effect is a gold rush to promote PM-fiber interaction, thus reaching high PM removal efficiency, decreasing airflow resistance, and achieving multifunctional applications simu...
Article
Electrostatic assisted air (EAA) coarse filters combine the benefits of electrostatic precipitators and fibrous filters, achieving high filtration efficiency for submicron particulate matters (PM), low pressure drop, and large dust-holding capacity. For application in heating, ventilation, and air conditioning (HVAC) systems, PM removal technology...
Article
Hydrogen peroxide (H2O2) solution and its aerosols are common disinfectants, especially for urgent reusage of personal protective equipment during COVID-19. Highly sensitive and selective evaluation of the H2O2 concentration is...
Article
In-situ thermally regenerated flexible adsorption films are superior for long-term purification of indoor low-concentration volatile organic compounds (VOCs). To further improve the adsorption kinetics of the films, the surface morphology of adsorption films was suggested in hierarchical channel structure. However, such structure is far from practi...

The rapid spread of COVID-19 and disruption of normal supply chains has resulted in severe shortages of personal protective equipment (PPE), particularly devices with few suppliers such as powered air-purifying respirators (PAPRs). A scarcity of information describing design and performance criteria for PAPRs represents a substantial barrier to mit...

Air Filtration In article number 2102051, Jinhan Mo, Guiyin Xu, Ju Li, and co-workers develop a two-stage electrostatically assisted air (EAA) filtration device with stage-I plasma charging and stage-II polydopamine coated polyethylene terephthalate (PET) coarse filters. By controlling the surface microstructure of the filters, the authors report a...

Background The COVID-19 pandemic has severely disrupted supply chains for many types of Personal Protective Equipment (PPE), particularly surgical N95 filtering facepiece respirators (FFRs; “masks”). As a consequence, an Emergency Use Authorization (EUA) from the FDA has allowed use of industrial N95 respirators and importation of N95-type masks ma...
Article
Full-text available
Personal protective equipment (PPE) is crucially important to the safety of both patients and medical personnel, particularly in the event of an infectious pandemic. As the incidence of Coronavirus Disease 2019 (COVID-19) increases exponentially in the United States and many parts of the world, healthcare provider demand for these necessities is cu...
Article
Airborne particulate matters (PM) pose serious health threats to the population, and efficient filtration is needed for indoor and vehicular environments. However, there is an intrinsic conflict between filtration efficiency, air resistance, and service life. In this study, a two‐stage electrostatically assisted air (EAA) filtration device is desig...
Article
Air filtration is of vital importance for creating healthy breathing indoor air. Particle filters can cause relatively high air resistance and large energy consumption in building ventilation systems. Electrostatically assisted metal foam (EAMF) filters have been developed to provide relatively high efficiency with low air resistance. This study re...

The COVID-19 pandemic has led to widespread shortages of personal protective equipment (PPE) for healthcare workers, including of N95 masks (filtering facepiece respirators; FFRs). These masks are intended for single use but their sterilization and subsequent reuse has the potential to substantially mitigate shortages. Here we investigate PPE steri...

Background: During the current COVID-19 pandemic, supply chains for Personal Protective Equipment (PPE) have been severely disrupted and many products, particularly surgical N95 filtering facepiece respirators (FFRs; "masks") are in short supply. As a consequence, an Emergency Use Authorization (EUA) from the FDA has allowed importation of N95-type...
Article
In air filtration for creating healthy indoor air, there is an intrinsic conflict between high filtration efficiency and low wind pressure drop. In this study, we overcame this conflict by developing new dielectric hetero-caking (HC) filters, in which high relative dielectric constant (εr) materials were heterogeneously loaded on the traditional po...

Objective: The COVID-19 pandemic has led to widespread shortages of personal protective equipment (PPE) for healthcare workers, including filtering facepiece respirators (FFRs) such as N95 masks. These masks are normally intended for single use, but their sterilization and subsequent reuse could substantially mitigate a world-wide shortage. Desig...
Article
The influx of ambient particulate matter (PM) to the indoor environment has threatened human health due to its adverse impacts on respiratory, cardiovascular, and neurological systems. Consequently, PM removal devices with high efficiency and low cost like electrostatic precipitator (ESP) are essential for a healthy and sustainable indoor environme...

The current COVID-19 pandemic has led to a dramatic shortage of masks and other personal protective equipment (PPE) in hospitals around the globe. One component of PPE that is in particular demand are disposable N95 face masks. To alleviate this, many methods of N95 mask sterilization have been studied and proposed with the hope of being able to sa...

High concentration particulate matter (PM) has been a serious environmental problem in China and other developing countries. Electrostatic-based purification technology is a method to remove airborne particles, and can reduce the energy consumption of ventilation fans in buildings because of its low pressure drop. In this study, we developed a new...

Electrostatically assisted air (EAA) coarse filter can improve the particle filtration performance of low efficiency filters without increasing their pressure drop. In this study, we investigated the long-term single pass filtration efficiency for 0.3 ~ 10 μm ambient particles, pressure drop, PM2.5 collecting amount, and energy consumption of an EA...
