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.

Supporting STEM Education and Professional Careers through the REU Program
The long term goals of the Triangle MRSEC REU program are to maximize opportunities for undergraduate involvement MRSEC research, recruit diverse undergraduate students from across the country, and encourage and support future careers in materials science and engineering. Our 2012 class of REU students represented a diverse group of undergraduates with 50% females and 75% underrepresented minorities.

Lasing from an electromagnetic hot spot
supported by coupled metal nanoparticles (NPs)
has been demonstrated for the first time. This
new nanolaser architecture is based on three
dimensional (3D) Au bowtie NPs supported by
an organic gain material. The extreme field
compression, and thus ultra-small mode
volume, within the bowtie gap produced laser
oscillations at the localized surface plasmon
resonance gap mode of the 3D bowties.
Transient absorption measurements confirmed
ultrafast resonant energy transfer between the

Harnessing In-Fiber Fluid Instabilities To Create Multimaterial Particles From Fibers
Ayman Abouraddy (UCF), Yoel Fink (MIT)
From drug delivery to catalysis
to optoelectronics, the need for efficient fabrication pathways
for particles
over a
wide range of sizes, from a variety of materials, and in many
different structures
is
critical to functionality. Researchers in IRG-III have exploited the inherent scalability
of fiber production and an in-fiber Plateau–Rayleigh capillary
