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

The Twist-Bend Nematic phase
LCMRC researchers have found an extraordinary nematic liquid crystal phase, a new entry in the most widely studied and widely applied class of liquid crystals. In the whole history of liquid crystals only four distinct nematic ground states have been found: the uniaxial, the biaxial, and, for chiral molecules, the helical nematic and blue phases.

Coupling a Single Electron Spin to a Microwave Cavity
K. D. Petersson (Princeton University), L. W. McFaul (Princeton University), M. D. Schroer (Princeton University), J. M. Taylor (Joint Quantum Institute), A. A. Houck (Princeton University), J. R. Petta (Princeton University)
IRG-D researchers at Princeton University have combined superconducting qubit technology with single spin devices, demonstrating that the microwave field of a superconducting resonator is sensitive to the spin of a single electron. The device may allow two spatially separated electron spins to be coupled, resulting in quantum entanglement.

A Key Signature of Dirac Fermions
Jun Xiong, Y.K. Luo, Y. H. Khoo, Shuang Jia, R. J. Cava and N. P. Ong (Princeton University)
In solids, the kinetic energy of an
electron generally increases as the square of its momentum. By contrast, in a
Topological Insulator such as Bi2Te2Se, electrons on the surface are
predicted to be Dirac Fermions for which the energy increases linearly with
momentum. In a magnetic field B, the
allowed states of an electron are quantized into Landau Levels (LLs). The
sequential emptying of occupied LLs in an increasing field leads to quantum
