Influence of Filter Inhomogeneity on Air Filtration of Nanoparticles
Collection efficiency Diffusional regime Fiber packing inhomogeneity Pressure drop
2016/3/28
Thermal rebound of nanoparticles on the surface of fibers is of big concern in collecting nanoparticles. Another factor
influencing the collection of nanoparticles is the inhomogeneity of fiber packi...
Nanoparticles in boreal forest and coastal environment: a comparison of observations and implications of the nucleation mechanism
Nanoparticles boreal forest coastal environment the nucleation mechanism
2010/8/16
The detailed mechanism of secondary new particle formation in the atmosphere is still under debate. It is proposed that particle formation happens via activation of 1–2 nm atmospheric neutral molecula...
Atmospheric Nanoparticles Impact Health, Weather Prof Says
Atmospheric Nanoparticles Health Weather
2010/3/4
Nanoparticles are atmospheric materials so small that they can’t be seen with the naked eye, but they can very visibly affect both weather patterns and human health all over the world – and not in a g...
An aerosol chamber investigation of the heterogeneous ice nucleating potential of refractory nanoparticles
aerosol chamber heterogeneous ice nucleating potential refractory nanoparticles

All samples were observed to initiate ice formation via the deposition mode at threshold ice super-saturations (RHithresh) ranging from 105% to 140% for temperatures below 220 K. Approximately 10% of ...
Negatively charged nanoparticles produced by splashing of water
Negatively charged nanoparticles splashing water

The production of splashing-generated balloelectric intermediate ions was studied by means of mobility spectrometry in the atmosphere during the rain and in a laboratory experiment simulating the heav...
From molecular clusters to nanoparticles: second-generation ion-mediated nucleation model
molecular clusters nanoparticles second-generation ion-mediated nucleation model
2009/1/19
Ions, which are generated in the atmosphere by galactic cosmic rays and other ionization sources, may play an important role in the formation of atmospheric aerosols. In the paper, a new second-genera...
Prompt deliquescence and efflorescence of aerosol nanoparticles
Prompt deliquescence efflorescence aerosol nanoparticles
2009/1/16
Literature reports have differed on the possibilities of discontinuous and continuous (i.e., prompt and nonprompt) deliquescence and efflorescence of aerosol particles in the nanosize regime. Experime...
