Polymer-Regulated Freezing of Water Droplets Revealed by Synchrotron X-ray Imaging and Raman Spectroscopy
Hyeonjun An, Bomi Kim, Jae Kwan Im +5
Adding a polymer to a sessile water droplet not only lowers its freezing point but also suppresses the tip singularity that forms during its freezing on cold substrates. Here, we e…

X-ray Microscopy Study of Freezing Sessile Droplets
Jae Kwan Im, Hyeonjun An, Seob-Gu Kim +2
A sessile water droplet on a cold substrate freezes into a shape with a sharp apex because of water's expansion upon freezing, yielding a universal tip angle across various conditi…
