Characterization of superhydrophobic surfaces for drag reduction in turbulent flow
After several years of study, our work on reducing drag in turbulent flow using superhydrophobic surfaces is published in the Journal of Fluid Mechanics! In this work we show how wettability and roughness contribute to turbulent drag reduction, and we design durable superhydrophobic surfaces that can reduce drag by more than 50% in highly turbulent flow conditions. This could significantly reduce the fuel usage or naval vessels. Check out the article!
Smooth, All-Solid, Low-Hysteresis, Omniphobic Surfaces with Enhanced Mechanical Durability
Matt’s work on fabricating low hysteresis, omniphobic surfaces is now published! Check it out here. This is the first report of omniphobic surfaces that can repel essentially all liquids without relying of fragile micro-texture or lubrication. Durability-wise, these surfaces maintain their liquid repellency far better than any other state-of-the-art coating!
ACS Spring 2018: New Orleans
Dr. Golovin will be presenting at the ACS Spring 2018 meeting in New Orleans. His talk will be from 2:20 – 2:45 on Wednesday, March 21st, in La Galerie 4 (New Orleans Marriott Canal Street). He’ll be discussing the latest work on icephobic polymers, this publication. All are welcome!
Students interested in joining Dr. Golovin’s group can arrange a time to meet in New Orleans.
ProQuest Distinguished Dissertation Award
Prof. Golovin wins the ProQuest Distinguished Dissertation Award from the University of Michigan. More information here: http://www.mse.engin.umich.edu/about/news/kevin-golovin-selected-to-receive-coveted-proquest-distinguished-dissertation-award-for-2017
Researcher Positions Available
The Golovin group is always looking for highly motivated students. If you are interested in joining the group, please send Dr. Golovin a cover letter and your CV, and let him know if you require funding. Postdoctoral scholars should also include a brief description of a potential project.
New publication!
Our framework on the design of icephobic surfaces using plasticized polymers has been published in Science Advances. Check it out here!
Megneto-Wheel
Iron oxide nanoparticles self-assemble in a droplet of water. The particle arrange in a very appealing pattern due to the coffee ring (or cheerio) effect.

One Red Hoodoo
Re-entrant texture is key to repelling low surface tension liquids like oils, alcohols, and solvents. Here a texture of “micro-hoodoos” is seen under SEM. False coloured. Image courtesy of Dr. K. Golovin. University of Michigan Materials Science & Engineering calendar winning image, 2016.
Blood-phobic
Superomniphobic surfaces are capable of repelling low surface tension liquids. Here, a superomniphobic aluminum surface (false coloured green) is shown under SEM repelling a droplet of silicone oil (false coloured red). Image courtesy of Dr. K. Golovin.
