Despite the fact that frequent aerosol formation has been observed in various locations in the atmosphere, the overall magnitude of the new particle formation as a particle source is still unclear. In order to understand the particle formation and growth processes, we investigate the magnitudes of the particle formation and growth rates at the size where the real atmospheric nucleation and acti...

Atmospheric particle number size distributions (size range 0.003–10μm) were measured between March 2008 and August 2009 at Shangdianzi (SDZ), a rural research station in the North China Plain. These measurements were made in an attempt to better characterize the tropospheric background aerosol in Northern China. The mean particle number concentrations of the total particle, as well as the nucle...

investigations in recent decades have shown an unexpected increase in aerosol concentrations in metropolitan and industrialized regions. it was sometimes followed by heat islands and probably decreases in precipitation due to an inadvertent cloud overseeding process. particle pollutants act like small cloud condensation nuclei in which they form large collections of small droplets in cloud. col...

This study investigates the mechanism of protein particle formation during ultrafiltration/diafiltration (UF/DF), finding that agitation drives particle formation by promoting protein-interface adsorption and desorption. Low conductivity and the presence of surfactant reduced the level of particle formation in small-scale stirring studies, and the same trends were observed in pumping and UF/DF....
