Prompt deliquescence and efflorescence of aerosol nanoparticles
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. Experiments reported herein using a hygroscopic tandem nano-differential mobility analyzer demonstrate prompt deliquescence and efflorescence of ammonium sulfate particles having diameters from 6 to 60 nm....
متن کاملDeliquescence and efflorescence of small particles.
We examine size-dependent deliquescence/efflorescence phase transformation for particles down to several nanometers in size. Thermodynamic properties of inorganic salt particles, coated with aqueous solution layers of varying thickness and surrounded by vapor, are analyzed. A thin layer criterion (TLC) is introduced to define a limiting deliquescence relative humidity (RH(D)) for small particle...
متن کاملQualitative light-scattering angular correlations of conglomerate particles.
The scattering phase functions of micrometer-sized glycerol droplets containing spherical latex inclusions undergo random fluctuations with time. We measure scattering intensities in the near-forward and near-backward scattering directions and find them to have strong positive correlations during some time periods and strong negative correlations during other time periods. The characteristic ti...
متن کاملContact efflorescence as a pathway for crystallization of atmospherically relevant particles.
Inadequate knowledge of the phase state of atmospheric particles represents a source of uncertainty in global climate and air quality models. Hygroscopic aqueous inorganic particles are often assumed to remain liquid throughout their atmospheric lifetime or only (re)crystallize at low relative humidity (RH) due to the kinetic limitations of efflorescence (salt crystal nucleation and growth from...
متن کاملUltraviolet broadband light scattering for single optically-trapped submicron- sized aerosol particles
The QBB trap (left panel in Fig. A) is composed of two perpendicularly arranged counterpropagating Bessel beam (CPBB) traps6, 7. The two sets of CPBB traps are obtained by splitting the beam from the trapping laser (Laser Quantum, OPUS 3 532 nm, typical power: 1000 mW) into two beams using a half-wave plate (λ/2) and a polarization beam splitter cube (PBC). From each of these two beams, a Besse...
