Program Highlights for year 2012
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
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
A new instrument allows the first imaging
of the movement of electrons in artificial materials
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.
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.
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
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.
Assembling microscopic particles
into macroscopic structures can open new pathways for producing complex
materials that cannot be produced by lithographic methods.
several methods for assembling colloidal particles exist, including controlled
drying, ionic interactions, and dipolar interactions, a general pathway for
In July, 2012, the UW-MRSEC hosted graduate students from the University of Puerto Rico
Mayaguez. While in Madison, Wisconsin the students performed their Science on
Wheels (Ciencias en Ruedas) show at the Wisconsin Institutes for Discovery on the
UW-Madison campus. The show teaches students about chemistry and physics
