  Penn Engineers Grow Liquid Crystal 'Flowers' That Can Be Used as Lenses
 
A team of material scientists, chemical engineers and physicists has made another advance in their effort to use liquid crystals as a medium for assembling structures. In earlier studies, the team produced patterns of "defects," useful disruptions in the repeating patterns found in liquid crystals. The new study adds a more complex pattern out of an even simpler template: a three-dimensional array in the shape of a flower.

  Nanotech Innovation Keeps Surfaces Clean and Transparent
 
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. A spin-off company from Penn Engineering has found a way to solve the problem of keeping surfaces clean, while also keeping them transparent.

Levitation of a Rare Earth Magnet

In the classroom of Daniel Gianola, the Meissner effect is demonstrated with a rare earth magnet above a YBCO high critical temperature superconductor. The superconductor discs were synthesized by undergraduate students as part of the course MSE 250, Nanoscale Materials Laboratory. Watch the video!

Smart Buildings

In the future, buildings may respond to their external environments. Led by Shu Yang, a research team has developed plans for a structure that will respond to its environment in order to optimize comfort, energy efficiency and aesthetic appeal. Learn more!
