A review of methodologies to measure the bipolar charge distribution of nanoparticles is
completed, including their advantages/disadvantages and sequential development. This …

In this study we investigated the effectiveness of air purifiers and in-line filters in ventilation
systems working simultaneously inside various classrooms at the University of Southern …

During the last three decades, the remarkable dynamic features of microelectromechanical
systems (MEMS) and nanoelectromechanical systems (NEMS), and advances in solid-state …

An electrostatic precipitator was evaluated to reduce nanometric and micron-sized particles
in indoor air environments. This process consists in a negative air ionizer assisted by a …

Since the discovery of the electron, the accurate detection of electrical charges has been a
dream of the scientific community. Owing to some remarkable advantages, micro …

Previous research has demonstrated that unipolar ionization can enhance the filter
performance to collect airborne particles, aeroallergens, and airborne microorganisms …

We have developed a novel ESP that uses an anticorrosive carbon brush precharger and
plastic collection plates into which metallic films are inserted. The collection efficiency of the …

In this study, we investigated the performance of an electrostatic precipitator (ESP) operating
at high flow rates (ie, 50–100 lpm) as a fine particulate matter (PM 2.5) collector for …

Oil mist poses a long-term threat to both the environment and human health, and the high
stability of fine oil mist particles makes them difficult to remove efficiently using traditional …

We developed and investigated the air cleaning performance of a novel electrostatic
precipitator (ESP)-type small air purifier with a carbon brush ionizer and an activated carbon …
