Phase behavior of asymmetric copolymers confined in thin films

Arash Nikoubashman, Richard A. Register, and Athanassios Z. Panagiotopoulos, Princeton Center for Complex Materials (PCCM), Princeton University
Thin block copolymer films are highly relevant for many scientific and industrial applications due to their ability to form uniform domains of controllable shape at nanometer length scales. From a technological point of view, the cases of shapes with long axes may be of interest in the fabrication of nanowires, while upright cylinders and spheres could have potential applications in the patterning of hexagonal arrays for data storage.

Lamination of undoped and doped organic homojunctions

A. Kahn and Y.-L. Loo, Princeton University
We investigated the electronic properties of interfaces between two laminated polymer films. The top polymer film (Fig. (a)) is transferred to a soft PDMS stamp, and laminated against the bottom film, previously spin-coated on a substrate. Using electron spectroscopy and Kelvin micro-probe techniques, we demonstrated that the process does not introduce any molecular shift due to interface dipole or surface states. We also showed that the interface is transparent to charge carrier transport, as shown in Fig. (b).

Growing Crystals of Topological Insulators

S. Jia, H. Ji, J. Xiong, H. Beidenkopf, A. Yazdani, N.P. Ong, and R.J. Cava Princeton University
Studying the electronic properties of the surface states on Topological Insulators requires high quality bulk crystals. We have figured out the defect chemistry of these compounds and grown crystals by the Bridgman Stockbarger method.

Complexity from Simplicity. Very Fine Art: Stunningly Beautiful Microscale Sculptures

Aizenberg, Mahadevan, Harvard University
 Artists and material scientists alike bend, melt and mold materials into useful and aesthetically pleasing forms. But nothing human hands have made can match the intricacy of convoluted corals or the delicate and unique geometry of a snowflake. In work reported in Science (May 17, 2013), Aizenberg, Mahadevan, and coworkers exploited nature’s sculpting methods to create visually stunning 3-D structures that may change the way nano- and micro-materials are made.

Hydroglyphics – Visualizing Patterns from Wetting Contrast. Writing Secret Messages with Water

Joanna Aizenberg, Harvard University
Joanna Aizenberg and her colleagues at the Harvard MRSEC developed Hydroglyphics to use readily accessible and safe materials to visually demonstrate the differences between hydrophobic and hydrophilic surfaces to a broad audience. This hands-on learning activity has been effective at teaching both elementary school students and their parents.

Perfectly Organized Gold Nanorings

S. Thayumanavan (University of Massachusetts at Amherst) and T. Russell (University of Massachusetts at Amherst)
Creating well-organized conducting nanostructures in a flexible polymer matrix provides platforms for numerous applications in optics, sensors, and wave-guiding structures.  Working in the Materials Research Science and Engineering Center (MRSEC) on Polymers at the University of Massachusetts Amherst, Thayumanavan and Russell achieved self-assembled hybrid structures from diblock copolymers and gold nanoparticles, where the
