American Chemical Society
Central Ohio Valley Section
This event is an informal get together for members of the section. This is a social meeting for us to get to know one another and family members are welcome to attend. Food, snacks and beverages will be provided by the section.
We are also inviting students from Chemistry programs at colleges located within the section.
In case of inclement weather, we will hold the picnic indoors on the fourth floor of the Science Building.

"Adhesion in Wet Environment: Inspiration from Nature"
AbstractWater is ubiquitous and it has a strong influence on performance of materials. The observations of corrosion of steel structures, peelings of paints, and degradation of composites are some striking examples that are influenced by exposure to humidity and water. Interestingly, nature has developed some unique approaches to protect and function under the influence of water. Geckos use tiny hydrophobic hairs to maintain strong adhesion in dry and wet conditions. Spiders use hygroscopic salts to maintain the glue wet and sticky. In my talk, I will present some unique ideas on how natural systems work under the influence of water. I will also present surface-sensitive analytical techniques we have developed to study the penetration of water and its influence on adhesion. I will discuss the implications of these findings in designing novel adhesives that could function in wet environments.
Ali Dhinojwala is H.A. Morton Professor of Polymer Science at The University of Akron. He obtained a Ph.D. in Chemical Engineering from Northwestern University and spent two years as a research scientist at University of Illinois at Urbana- Champaign. After spending one year at GE Plastics, Dr. Dhinojwala joined The University of Akron in 1997. His current research is in the areas of adhesion, friction, and wetting. His group has developed unique surface technique to study buried polymer interfaces. His recent interest is in understanding how geckos and spiders use adhesives for locomotion and prey capture. These studies have led his team to develop synthetic adhesives using aligned carbon nanotubes.
Awards and Accomplishments include 3M Young Faculty Award, NSF Creativity Award, CAREER Award given by The National Science Foundation, Omnova Signature University Award Outstanding Researcher of the Year, University of Akron, and Whitby Award for Teaching and Research from the Rubber Division
