Active Emulsion droplet arrays
Irv Epstein, Seth Fraden, Bing Xu
Stabilized
emulsions containing the oscillating Belousov - Zhabotinsky chemical reaction (BZ) show interesting dynamics. Each drop acts as an independent chemical clock.
However, they chemically communicate and exhibit collective behavior. In (a)
six BZ drops are contained in a
capillary tube. The white bars
are light, which set the oscillators in the reduced state. Drops 1 & 6 are
always exposed to light, setting the boundary conditions. Drops 3 & 4 are

How the weak becomes strong: spider silk reveals a paradox of super-strength
Markus Buehler (MIT)
Since its development in China thousands of years ago, silk from
silkworms, spiders and other insects has been used for high-end, luxury
fabrics as well as for parachutes and medical sutures. Now, MRSEC
supported researchers are untangling some of its most closely guarded
secrets, and explaining why silk is so strong, a question that has
remained unresolved. Buehler and co-workers of the MIT MRSEC IRG-II have

Aharonov-Bohm Effect in Neutral Excitons
Greg Salamo, Physics, University of Arkansas
We have made the first experimental observation of the Aharonov-Bohm effect in neutral excitons. In classical mechanics the motion of an electrical charged particle is only affected if the particle enters a region of space with a magnetic or electric field.

Portable SEM for K-12 Schools
Greg Salamo, UA; Matthew Johnson, OU
Expanding outreach with portable SEM for K-12 math/science. Last year MRSEC graduate students at the University of Arkansas brought cutting edge microscopy to local middle-school students and allow them to explore the world of nanoscience in real-time. This year our focus expanded to regional high-school students. The microscope is a portable scanning electron microscope (SEM). The SEM allows the students to explore the world of the “nano”.

Biofabrication of ZnS-binding immuno-quantum dots
A designer protein combining ZnS mineralizing activity with IgG adaptor
capability was built and used for easy and rapid aqueous synthesis of
immuno-QDs. The particles consist of a ≈ 4 nm ZnS wurtzite core, can be
derivatized with a wide variety of unmodified antibodies, and have
ultrasmall (14 nm) diameters.

Undergraduate Partnership with Cal Poly Pomona
The LCMRCconducts collaborative research with Cal Poly Pomona, a Hispanic
Serving Institution. Cal Poly Chemistry Juniors work in the Department’s
research laboratory for two quarters during the AY, then continue their
research full time at the LCMRC labs in Boulder during the summer. Cal Poly
students are able able to take advantage of
the dynamic atmosphere and interdisciplinary expertise of the LCMRC and use

Light and Energy
A new Materials Science From CU program, Light and Energy, enables
students to compare the amount of energy needed to illuminate different types
light bulbs. Seen in this photo during
the annual STEMapaloozza event held in
Denver, Center graduate student Chenhui Zhu encourages a middle student to generate the power
to light an array of incandescent light bulbs.

Cool and Creative Chemistry
Cool and Creative Chemistry is one of the interactive classes of the LCMRC Materials Science from CU K-12 outreach program. MSFCU presentations, designed by Center
faculty and students, have been
presented to 65,000 Colorado children over the past 10 years. The photo was taken during a presentation at
Super Science Saturday at the Steelworks Museum of Industry & Culture in
Pueblo, Colorado. Photo: John Jaques/Pueblo
