DOI: 10.1126/sciadv.aax0746
Abstract: Hydrophilic solid surfaces having low contact angle hysteresis can induce stable dropwise condensation. Droplet nucleation and condensation are ubiquitous phenomena in nature and industry. Over the past century, research has shown dropwise condensation heat transfer… read more here.
