A team of material scientists, chemical engineers and physicists from the University of Pennsylvania has made another advance in their effort to use liquid crystals as a medium for assembling structures. In their earlier studies, the team produced patterns of “defects,” useful disruptions in the repeating patterns found in liquid crystals, in nanoscale grids and rings. The new study adds a more complex pattern out of an even simpler template: a three-dimensional array in the shape of a flower.

NSF news. (Dec. 18. 2013)
Hanging hundreds of feet off the ground to wash a skyscraper's windows or pumping water out to a desert solar array to keep its panels and mirrors clean is more than just a hassle—it's an expensive problem with serious ecological implications.
Researchers at Penn and the spin off company has found a way to solve the problem of keeping surfaces clean, while also keeping them transparent.
Penn researchers integrate origami and engineering (May 30, 2013)
The quintessential piece of origami might be a decorative paper crane, but in the hands of an interdisciplinary Penn research team, it could lead to a drug-delivery device, an emergency shelter, or even a space station.
Led by Randall Kamien, a professor in the Department of Physics and Astronomy, the Penn team will collaborate with researchers at Cornell University on the National Science Foundation’s Emerging Frontiers in Research and Innovation Program called ODISSEI, or Origami Design For The Integration Of Self-assembling Systems For Engineering Innovation.
The project draws inspiration from the Japanese art of paper folding, but the Penn team suggested adding a variant of the technique, known as kirigami, in which the paper can be cut as well as folded. Allowing for cuts and holes in the material makes it easier to fold rigid, three-dimensional structures.
