Highly Stretchable and Tough Hydrogels
Sun, J.-Y., X. Zhao, W. R. K. Illeperuma, O. Chaudhuri, K. H. Oh, D. J. Mooney, J. J. Vlassak and Z. Suo
Hydrogels are used as scaffolds for
tissue engineering, vehicles for drug delivery, actuators for optics and
fluidics, and model extracellular matrices for biological
studies. The scope of hydrogel applications, however, is often severely limited
by their mechanical behaviors. Most hydrogels are brittle, sensitive to
notches, and do not exhibit high stretchability. We report the synthesis of hydrogels
from polymers forming ionically and covalently crosslinked networks.
Although such gels contain 90% water, they can be stretched beyond 20 times

Precise Stitching, Not Patch Size, Determines the Quality of Atomic Quilts
A. W. Tsen, et al. Science, in press.
Intergrain stitching determines electrical conductance across graphene grain boundaries
The outstanding electronic and mechanical properties of
single-atom-thick layers of carbon, so-called “graphene” films, make
them ideal for next-generation solar cells and transistors. However,
attempts to grow these films over large areas invariably lead to
quilt-like structures of interconnected atomically-perfect patches

Next Generation Materials for Plasmonics and Organic Spintronics (2011)
Spin Organic Light Emitting Diodes (OLED)
Objective: Develop and characterize OLEDs based on spin-aligned carrier injection of which electro-luminescence (EL) is controlled by magnetic field.
Approach: Use ferromagnetic cathode and anode that work as bipolar spin- valve injecting both electrons and holes into a deuterated π-conjugated polymer.

2012 Research Experience for Undergraduates Summer Program
Utah MRSEC sponsored 10 undergrads to work with faculty and graduate student mentors in their labs for a 9-week research program. Research opportunities for Utah MRSEC REU students are of an interdisciplinary focus on topics such as plasmonic metamaterials, and spin effects in organic LEDs & solar cells. Researchers and selected students are from fields such as materials science, electrical engineering, physics, chemistry and applied math.

Periciliary Brush Keeps Lungs Healthy
Brian Button, Li-Heng Cai, Camille Ehre, Mehmet Kesimer, David B. Hill, John K. Sheehan, Richard C. Boucher, and Michael Rubinstein
Mucus clearance is the primary defense
mechanism that protects airways from inhaled infectious and toxic agents. In
the current Gel-on-Liquid mucus clearance model mucus gel is propelled on top
of a “watery” periciliary layer surrounding the cilia. However,
this model fails to explain the formation of distinct mucus layer in health or
why mucus clearance fails in disease. We propose a Gel-on-Brush model in which
the periciliary
layer is occupied by membrane spanning mucins and mucopolysaccharides densely tethered to the airway surface.

Summer School on “Polymers in Soft and Biological Matter"
Dr. Michael Rubinstein, University of North Carolina, Chapel Hill
Founded by physical chemists like Flory and brought into the mainstream of theoretical physics by visionaries like de Gennes, over the last eighty years polymer physics has grown into a mature, rich, and exciting discipline. Now expanded to include also colloids, liquid crystals, interfaces, etc, polymer and soft matter physics span fundamental statistical mechanics and field theory, most advanced materials, as well as technological and biological frontiers.
