Directed bonding colloidal assemblies
Y. Wang, Y. Wang, D. R. Breed, V. N. Manoharan, L. Feng, A. D. Hollingsworth, M. Weck, D. J. Pine
•The
ability to design and assemble three-dimensional structures from colloidal
particles, such as open structures for photonic band gap applications, is
limited by the absence of specific directional bonds.

Finding a glass needle in a haystack
S.Y. Ding, Y.H. Liu, Y.L. Li, S.W. Sohn, C. S. O’Hern, A. Taylor, and J. Schroers (Yale University)
Metals that are glasses and can be formed like plastics are called bulk metallic glasses (BMG). But not all metals can be glasses and one has to sort through a large number of chemical compositions to find a good BMG. a trial and error processes could take up to a day to decide if a single composition can be molded. Sorting through hundreds of BMGs that are composed of four chemical elements would take up to a year. Now, with CRISP’s new combinatorial deposition system, more than 800 different compositions can be synthesized and characterized in a day.

Engineering the Electronic Structure of Crystalline Oxide Layers

One avenue to creating new materials with useful electronic properties is to take existing materials and modify their structure at the level of the bonds between the constituent atoms: this is feasible because the distribution of electrons around an atom is sensitive to subtle atomic-scale distortion of its bonds. For this type of approach to succeed, one needs theoretical input on how the atoms should be arranged to achieve some desired electronic distribution.

Spontaneous Motion in Hierarchically Assembled Active matter
T. Sanchez, D. Chen, S. DeCamp and Z. Dogic
Most conventional materials are assembled from inanimate building blocks. We have explored the behavior of soft materials in which constituent energy consuming units that are assembled from animate energy consuming components. Thousands of these components spontaneously coordinate their microscopic activity to yield novel gels, liquid crystals and emulsions that crawl, flow, stream, spontaneously fracture and self-heal, thus mimicking some of the characteristics of living biological organisms.

A New Mechanism for Flagella-Like Beating
R. Chelakkot, A. Gopinath, L. Mahadevan, M. F. Hagan
The
planar dynamics of a semi-flexible filament anchored at one end and comprised
of connected, self-propelled, spheres were predicted using Brownian dynamics
simulations and continuum elastic theory theory.
For certain parameter ranges the filament undergoes periodic motion. With a
clamped anchor, the filament undergoes flagella-like beating (top right), while
a pivoting end leads to a steadily rotating coiled conformation (bottom right).

Bridge Program for Physics Graduate Students
OSU, CEM and the OSU Department of Physics have established
and funded a M.S.‐to‐Ph.D. Bridge Program at OSU; OSU is one of
the first sites funded by the American Physical Society Bridge
Program. The program seeks to enhance the diversity of qualified
applicants to physics Ph.D. programs at OSU and at other
universities. The first cohort of students for this 2‐year transitional
M.S. program will begin in June 2013.

Researchers Discover the Grail of Graphene Electronics: Semiconducting Graphene
J. Hicks, M. Nevious, C. Berger, W.A. de Heer and E.H. Conrad
Researchers Discover the Grail of Graphene Electronics: Semiconducting Graphene (.PDF)
The stumbling block to developing graphene electronics has been the inability to produce a semiconducting form of graphene. Researchers at the Georgia Tech MRSEC have finally found a solution to this elusive goal, graphene bent over SiC steps. This semiconducting graphene can operate at temperatures above 200 C and is easily scalable to industrial fabrication.
