Printed, Flexible Carbon Nanotube Digital Circuits

Dan Frisbie
Graduate student Mingjing Ha working with Optomec, Inc. and Northwestern University collaborators (Mark Hersam) has demonstrated low voltage, fast carbon nanotube (CNT) circuits printed on flexible plastic substrates. The circuits are fabricated by aerosol jet printing from a liquid dielectric ink (ion gel) and a purified semiconducting CNT ink (Northwestern). The printed semiconducting CNTs form the channels in thin film transistors and printed circuits.
Method to fabricate ZnO nanowire matrices in a microfluidic channel. By controlling the seeding step, nanowire matrices of different densities are fabricated without using any nanopatterning steps.

Discovery of a Frank-Kasper σ Phase in Sphere-Forming Block Copolymer Melts

Frank Bates
Ordering of spherical particles represents a fundamental topic in materials science and engineering ranging from the sub-nanometer scale packing of atoms in simple crystals to micron sized assemblies of colloids.

Pleats on Crystals on Curved Surfaces

W.T.M. Irvine, V. Vitteli, P. M. Chaikin
Electrically charged polymer colloids attracted to the surface of water droplets of different shapes crystallize on their curved surfaces. ŸThe curvature frustrates perfect crystallization and defects must be added such as the familiar twelve pentagons which decorate the otherwise hexagonal faces of a soccer ball. The pentagons/disclinations strongly relax curvature.

Lateral Organic Devices

B. M. Dhar, G. S. Kini, G. Xia, B. J. Jung, N. Markovic, and H. E. Katz
Background: Most organic devices, from organic light emitting diodes to organic spintronic devices vertical devices, where the essential interfaces are buried and thus not subject to investigation.
