Analysis of atmospheric visibility degradation in early haze based on the nucleation clustering model
Early haze Initial nucleation process Heterogeneous cluster Visible-light absorption
2023/3/1
The initial nucleation of ultrafine particle recently attracts more attention as a key factor in visibility degradation during early haze. In this study, we have performed Density Functional Theory (D...
Surface Nanobubble Nucleation Visualized with TIRF Microscopy
Surface Nanobubble Nucleation Visualized TIRF Microscopy Fluid Dynamics
2012/4/24
Nanobubbles are observed with optical microscopy using the total internal reflection fluorescence (TIRF) excitation. We report on TIRF visualization using Rhodamine 6G at 5$\mu\,$M concentration which...
Distributional fixed point equations for island nucleation in one dimension: a retrospective approach for capture zone scaling
Gap size distribution capture zone distribution
2012/2/27
The distribution of the capture zones of point islands nucleated in one dimension are considered using a retrospective view, providing an alternative perspective on why scaling occurs in this continuo...
