Fig. 1 shows the schematic diagram of the experimental apparatus of explosion inhibition by ultrafine water mist. Base on the apparatus which was introduced in our earlier works [24], partial change was conducted in present experiments.The apparatus includes a combustion chamber with glass window, a gas supply system, an ultrasonic atomization system, an

For instance, the Coway Airmega 400 is widely regarded as one of the best air purifiers for removing ultrafine particles. It contains both an activated carbon filter and a Green True ^™ filter. The Airmega 400 effectively filters 99.999%¹ of nano-sized pollutants down to 0.01 microns in rooms up to 1,560 square feet. With a filter that lasts

Heterogeneities in inflammatory and cytotoxic responses of

We investigated the cytotoxic and inflammatory activities of size-segregated particulate samples (particulate matter, PM) from contrasting air pollution situations in Europe. Coarse (PM10-2.5), fine (PM2.5-0.2), and ultrafine (PM0.2) particulate samples were collected with a

1. Introduction. Air pollution from various sources continues to produce enormous economic and health burden for populations across the world (Cohen et al., 2017; Gakidou et al., 2017; McDuffie et al., 2021).The burden of premature mortality attributable to air pollution has been estimated to be up to about 9 million deaths per year globally (Burnett et al., 2018).

Previous research has demonstrated that unipolar ionization can enhance the filter performance to collect airborne particles, aeroallergens, and airborne microorganisms, without affecting the filter pressure drop. However, there is a lack of research on the long-term system performance as well as the influence of environmental and operational parameters. In

The suppression effect of ultrafine mists on methane/air explosions with methane concentrations of 6.5%, 8%, 9.5%, 11%, and 13.5% were experimentally studied in a closed visual vessel. Ultrafine water/NaCl solution mist as well as pure water mist was adopted and the droplet sizes of mists were measured by phase doppler particle analyzer (PDPA).

Ultrafine water mist, especial the less than 50 μm diameter with a large specific surface area, has been considered as an excellent inhibitor with a good application prospect and plays the both physical and chemical effects during the explosion inhibition [6]. Suppression of methane/air explosion by ultrafine water mist containing sodium

High concentrations of aerosol particles is a severe air pollution problem in Chinese urban agglomerations (Kulmala, 2015), which increases disease burden (Cohen et al., 2017). Currently, air quality standards for Chinese cities consider particle mass instead of number concentration (WHO, 2000). The ultrafine particles
