The winners of the Art Matters exhibition were chosen by popular vote from the audience. Congratulations to these individuals and many thanks to all of the contributors for sharing a bit of the beauty they found in science and engineering!
1st place: Wathsala Jayawardana ---- North Dakota State University
This is a result of a small experiment done under extremely cold weather in Fargo, ND. This phenomenon happened when it was below -20°C.
2nd place: Alexandra R. Spitzer --- University of Illinois Urbana-Champaign
Micro-osmotic actuators bulge as water permeates through thin polydimethylsiloxane (PDMS) membranes due to an osmotic potential difference between an encapsulated salt solution inside the actuator and the surrounding pure water. The elastic nature of PDMS allows for large deformations of the thin films, resulting in these balloon-like PDMS membranes.
3rd place: Paul Lilin --- Massachusetts Institute of Technology
A microliter drop of a 10% aqueous suspension of polystyrene nanoparticles displays an intricate crack pattern as it dries on a glass substrate. A 6-minute time-lapse reconstruction shows the growth of a solid deposit starting from the drop perimeter, and the appearance of radial cracks soon followed by branching orthoradial cracks. The deposit diameter is 2.1 mm.
