I have splendid news to conclude this weekend's blogging. Our paper "Surface pinning explains the low heat transfer coefficient between water and a carbon nanotube film" was accepted for publication in Carbon a few days ago. The paper is about a very peculiar phenomenon observed by Betty: the heat transfer coefficient between carboxy-functionalied MWCNT buckypaper and a sessile water droplet is less than half of that between unfunctionalized MWCNT buckypaper and water. This is a major surprise at first glance because intuition suggests that the more hydrophilic buckypaper should be the better performer. We were able to explain the phenomenon on the basis of the layered structure of buckypaper and the localization of the droplet on the top of the buckypaper.
I am very proud of this paper, a truly joint effort by all co-authors: Erzsébet-Sára Bogya has made the measurements and the data analysis and Botond Szilágyi developed the theoretical model and run the fitting and I initiated the discussion and polished their manuscript a bit. Task distribution worked very well. I am thankful to both co-authors and sincerely hope to continue working together in this fashion.
