Rapid and Surfactant-Free Fabrication Method for Sizable Carbon Nanotube Membranes
Carbon nanotubes (CNT) can be manufactured into thin films for a variety of applications such as filtration and construction. To work effectively in these applications, large area films are necessary. Unfortunately, standard approaches to CNT manufacture are only able to produce small area materials through a complex, expensive process which requires...

Mechanophore-Grafted Polymers to Form Stress-Responsive Thermoset Network
Identifying damage detection is critical in many industries to reduce catastrophic failure. Mechanochemistry is the study of stress-responsive molecular units that sense force changes in their local environment to allow for determination of the stress, strain, or damage applied. Certain mechanophores have a florescent emission when undergoing stress....

In-situ damage detection system for mechanpohore-embedded fiber reinforced composites
Composites often fail due to mechanical wear, abrasion, friction and stress they experience during use. Mechanophores have emerged as a strategy for detecting damage caused by these mechanical loads. Mechanophores embedded in composites undergo a chemical reaction when significant damage occurs and typically change to a fluorescent color as a signal...
