Developed and taught a senior-level course in physics
(PHY427/527) called 'Nanoscience and Nanotechnology'. 50% of the
course is a lecture and 50% hands-on work in my cleanroom

We demonstrated the spontaneous motion of water droplets on horizontal surface by designing surface tension gradients on the surfaces of Cu and Al.
The surface tension (i.e. capillary) force is capable of moving water droplets vertically against gravity for about 2 centimeters.
"Chemical" surface tension gradients are created using self-assembled monolayers while 'bare metal' gradients are prepared using laser etching
Currently investigating the use of the same techniques to move ferrofluid droplets.
This work is highly relevant for the efficient use of energy by eliminating water droplets on heat exchangers and in lab-on-a-chip applications
