Penn researchers grow liquid crystal ‘flowers’ that can be used as lenses

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. Their earlier studies 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 shaped like a flower.
