Award-Winning Invention

Dr. David Chao (left), Dr. Negli Zhang and Dr. John Sankovic (not pictured) created the award-winning Multidimensional Contact Angle Measurement Device (MCAMD). This breakthrough technology helps engineers understand how liquids spread on different surfaces. This phenomenon is critical to many industries, including paints, coatings and lubricants. In space applications, it is important for determining the optimal performance of heat pipes and fuel tanks. The MCAMD can provide a 360-degree view of the liquid spreading process, rather than only the side view available with previously existing devices. It costs up to 15 times less than current, less-capable commercial systems.
