Penn researchers grow liquid crystal 'flowers' that can be used as lenses
December 18, 2013
A team of material scientists, chemical engineers and physicists at the University of Pennsylvania has made another advance in their effort to use liquid crystals as a medium for assembling structures. Their earlier studies produced patterns of "defects," useful disruptions in the repeating patterns found in liquid crystals and in nanoscale grids and rings. The new study adds a more complex pattern out of an even simpler template: a 3-D array shaped like a flower.

The National Science Foundation (NSF) is an independent federal agency that supports fundamental research and education across all fields of science and engineering. In fiscal year (FY) 2017, its budget is $7.5 billion. NSF funds reach all 50 states through grants to nearly 2,000 colleges, universities and other institutions. Each year, NSF receives more than 48,000 competitive proposals for funding and makes about 12,000 new funding awards.
