Researchers grow carbon nanofibers using ambient air (March 24, 2014). NC State researchers have demonstrated that vertically aligned carbon nanofibers (VACNFs) can be manufactured using ambient air, making the manufacturing process safer and less expensive. VACNFs hold promise for use in gene-delivery tools, sensors, batteries, and other technologies. Conventional techniques for creating VACNFs rely on the use of ammonia gas, which is toxic. “This discovery makes VACNF manufacture safer and cheaper, because you don’t need to account for the risks and costs associated with ammonia gas,” says Dr. Anatoli Melechko, an adjunct associate professor of materials science and engineering and senior author of a paper on the work.

Carbonell elected to National Academy of Engineering (February 7, 2014). Dr. Ruben Carbonell, Frank Hawkins Kenan Distinguished Professor of Chemical Engineering at NC State, has been elected to the National Academy of Engineering (NAE). Carbonell is one of 67 new members and 11 foreign associates announced today. He is the 12th current NC State faculty member to be elected to the NAE, a private, independent nonprofit organization that provides engineering leadership in service to the nation.

Silver nanowire sensors hold promise for prosthetics, robotics (January 16, 2014). NC State researchers have used silver nanowires to develop wearable, multifunctional sensors that could be used in biomedical, military or athletic applications, including new prosthetics, robotic systems and flexible touch panels. The sensors can measure strain, pressure, human touch and bioelectronic signals such as electrocardiograms. NC State News Service

Battery design gets boost from aligned carbon nanotubes (August 6, 2013). NC State researchers have created a new flexible nano-scaffold for rechargeable lithium ion batteries that could help make cell phone and electric car batteries last longer. The research, published online in Advanced Materials, shows the potential of manufactured sheets of aligned carbon nanotubes coated with silicon, a material with a much higher energy storage capacity than the graphite composites typically used in lithium ion batteries.
