Energy-harvesting yarn Researchers at the University of Texas at Dallas and Hanyang University in South Korea developed a carbon nanotube yarn that generates electricity when stretched or twisted. Possible applications for the so-called "twistron" yarns include harvesting energy from the motion of ocean waves or from temperature fluctuations. When sewn into a shirt, these yarns served as a sel... » read more

Modified carbon nanotubes used to track individual cells Carbon nanotubes come to the forefront of scientific research yet again, this time for serving as the most sensitive molecular sensing platforms available. MIT engineers believe they have designed sensors that, for the first time, can detect single protein molecules as they are secreted by cells or even a single cell. The sensors that... » read more

Stamping with electronic ink Engineers at MIT fabricated a stamp made from carbon nanotubes that is able to print electronic inks onto rigid and flexible surfaces. The team's stamping process should be able to print transistors small enough to control individual pixels in high-resolution displays and touchscreens, said A. John Hart, associate professor of contemporary technology and mecha... » read more

Getting to 1nm Researchers at the Lawrence Berkeley National Laboratory, UC Berkeley, University of Texas at Dallas, and Stanford University created a transistor with a working 1nm gate from carbon nanotubes and molybdenum disulfide (MoS2). "The semiconductor industry has long assumed that any gate below 5 nanometers wouldn't work, so anything below that was not even considered," said fir... » read more

Carbon nanotube transistors outperform silicon University of Wisconsin-Madison materials engineers created carbon nanotube transistors that outperform silicon transistors, improving the current 1.9 times. The new transistors are particularly promising for wireless communications technologies that require a lot of current flowing across a relatively small area. "This achievement has been a... » read more
