Cyberlearning: Materials iLab
11,586 users worldwide have run nearly 16,643 experiments to date
• iLabs are online experimental tools that allow pre-college and college students to access scientific instruments housed at universities to conduct experiments via the internet.
• Use of iLabs has been shown to improve student inquiry skills and experimental design skills resulting in more authentic scientific investigations

Partnership with Museum of Science and Industry
• The NU-MRSEC has partnered with the Chicago Museum of Science and Industry to create a new exhibit focused on materials science and society, scheduled to debut in Spring 2015.
• The exhibit is designed in a manner that it can be easily moved to other locations following its run at the Chicago MSI.
• Approximately 1.5 million guests, including >300,000 children in school groups visit the Museum annually.

Soft Robotic Concepts in Catheter Design: an On-demand Fouling-release Urinary Catheter
Biofilms
form on submerged or moist surfaces when bacteria attach and excrete slimy
biopolymers to protect themselves,
and they are particularly problematic when they develop on urinary
catheters.

Phase Transformations in Binary Colloidal Monolayers
Diffusionless martensitic transformations are a class of solid–solid phase transitions in which the crystal unit cell changes shape and internal structure, while keeping its stoichiometry constant. Because these transformations do not require long-range diffusion, they are fast and repeatable, and thus have been exploited in a number of engineeringapplications.

Shape-Shifting Liquid Metal Becomes a Reality
Terminator
2 is
widely remembered for its
metal shape-shifting
villain.
Impervious
to
bullets, explosives,
and fire,
the T-1000
robot was
capable of changing shape at will. Researchers at the
North Carolina State University
have taken a step towards
making science fiction a
reality by developing a technique for controlling the surface tension of liquid
metals using very low voltages. This technology paves the way for shape-reconfigurable
metal

Probing spin and charge on the nanoscale
We are building a scanning probe microscope to study spin and charge on the nanoscale. The magnetic sensing element is a nitrogen-vacancy center (NV) in diamond, which should afford single electron spin sensitivity with 10 nm spatial resolution.
