|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.

|Penn Engineers Model a Key Breaking Point Involved in Traumatic Brain Injury|
|Even the mildest form of a traumatic brain injury, better known as a concussion, can deal permanent, irreparable damage. Now, an interdisciplinary collaboration is using mathematical modeling to better understand the mechanisms at play in this kind of injury, with an eye toward protecting the brain from its long-term consequences. The findings shed new light on the mechanical properties of a critical brain protein and its role in the elasticity of axons, the long, tendril-like part of brain cells.|

|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.
