ANN ARBOR, Mich

.— Twisting spires, concentric rings, and gracefully bending petals are a few of the new three-dimensional shapes that University of Michigan engineers can make from carbon nanotubes using a new manufacturing process.

The process is called “capillary forming,” and it takes advantage of capillary action, the phenomenon at work when liquids seem to defy gravity and spontaneously travel up a drinking straw.

The new miniature shapes have the potential to harness the exceptional mechanical, thermal, electrical, and chemical properties of carbon nanotubes in a scalable fashion, said A. John Hart, an assistant professor in the Department of Mechanical Engineering and in the School of Art & Design.

The 3D nanotube structures could enable countless new materials and microdevices, including probes that can interface with individual cells, novel microfluidic devices, and lightweight materials for aircraft and spacecraft. (more…)

ANN ARBOR, Mich.— High blood lipids are a big risk factor for developing heart disease, which is the leading cause of death in the United States. Approximately one of every six adult Americans has high blood cholesterol and about every 25 seconds, an American will have a heart attack, and nearly one every minute will die from it, according to the Centers for Disease Control and Prevention.
