Researchers at Rice and Swansea universities have developed a technique to use inexpensive newsprint harvested from newspapers to grow carbon nanotubes for industry. More specifically, the scientists have shown that a particular kind of newsprint can be treated to serve as a three-dimensional substrate for single-walled carbon nanotube growth.

Perovskite nanocrystals hold promise for improving a wide variety of optoelectronic devices, but problems with their durability still limit the material's broad commercial use. Researchers at the Georgia Institute of Technology have demonstrated a novel approach aimed at addressing the material's durability problem: encasing the perovskite inside a double-layer protection system made from plastic and silica.

Researchers at The University of Texas at Austin and the University of California, Riverside have found a way to transfer energy between silicon and organic, carbon-based molecules—a breakthrough that has implications for information storage in quantum computing, solar energy conversion, and medical imaging. The discovery provides a way to boost silicon's efficiency by pairing it with a carbon-based material that converts blue photons into pairs of red photons that can be more efficiently used by silicon.

The University of Southern California has partnered with Carbonics, Inc., to develop a carbon nanotube technology that, for the first time, achieved speeds exceeding 100 gigahertz in radio frequency applications. The milestone eclipses the performance of traditional Radio Frequency Complementary Metal-Oxide Semiconductor (RF-CMOS) technology, which is ubiquitous in modern consumer electronics, including cell phones.

Scientists at Cornell University have used magnets to design self-assembling systems that could be created in nanoscale form. The researchers made centimeter-sized acrylic panels, each containing four tiny magnets in a square pattern. To activate the self-assembly, the magnets were scattered on a shaker table, with the table’s vibrations preventing the magnets from forming bonds. As the shaking amplitude was decreased, the magnets attached in their designated order and formed the target structures. While nanoscale machines and self-assembling systems are not new, this project marks the first time the two concepts have been combined with magnetic encoding.
