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 (.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.

Mussel protein adhesion to mica surpasses biotin-avidin affinity
Danner, Kan, Hammer, Israelachvili & Waite
Asymmetrical films of adhesive protein Mfp-5 show significantly higher reversible adhesion to smooth mica surfaces than the “gold standard” of noncovalent binding: well-ordered avidin-biotin interactions. The insights are crucial for intelligent translation of mussel adhesion to engineered systems.

Teachers Merge Art and Science at the UCSB MRSEC
The
UCSB Materials Research Laboratory’s “Models and Materials” Teacher Institute
teamed secondary art and science teachers to develop interdisciplinary
curriculum projects combining art and science with student-created models. Five
science and four art teachers from Santa Barbara and Ventura County schools
participated in this teacher professional development opportunity and presented
their lesson plans at the MRL Secondary Curriculum Workshop in March 2013.

Altering crystal structure of unique magnetic films manipulates magnetization orientation
Magnetic anisotropy defines the functionality in many
applications including magnetic data storage, strong
permanent magnets, and electrical transformers.
Sr2FeMoO6 (SFMO) and Sr2CrReO6 (SCRO) are unique
magnetic materials whose strong anisotropy aligns with
crystalline structure (“magneto‐crystalline anisotropy”)
that arises from the heavy elements Mo and Re.
