University of Pennsylvania 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...

New Level Of Control Over Liquid Crystals Shown By Penn Researchers
2013-01-07 13:50:26

University of Pennsylvania Directed assembly is a growing field of research in nanotechnology in which scientists and engineers aim to manufacture structures on the smallest scales without having to individually manipulate each component. Rather, they set out precisely defined starting conditions and let the physics and chemistry that govern those components do the rest. An interdisciplinary team of researchers from the University of Pennsylvania has shown a new way to direct the...
