Breakthrough discovery is 10 times longer than previous current-carrying nanotubes, paves way for supercomputer and health care applications
UC Irvine today announced that scientists at The Henry Samueli School of Engineering have synthesized the world’s longest electrically conducting nanotubes. These 0.4 cm nanotubes are 10 times longer than previously created electrically conducting nanotubes. The breakthrough discovery may lead to the development of extremely strong, lightweight materials and ultradense nano-memory arrays for extremely powerful computers, ultralow-loss power transmission lines, and nano-biosensors for use in health care applications.
A nanotube is commonly made from carbon and consists of a graphite sheet seamlessly wrapped into a cylinder only a few nanometers wide. A nanometer is one billionth of a meter, about the size of 10 atoms strung together.

Tiny pores at a cell's entryway act as miniature bouncers, letting in some electrically charged atoms--ions--but blocking others. Operating as exquisitely sensitive filters, these "ion channels" play a critical role in biological functions such as muscle contraction and the firing of brain cells.
To rapidly transport the right ions through the cell membrane, the tiny channels rely on a complex interplay between the ions and surrounding molecules,...
The miniaturization of the current technology of storage media is hindered by fundamental limits of quantum mechanics. A new approach consists in using so-called spin-crossover molecules as the smallest possible storage unit. Similar to normal hard drives, these special molecules can save information via their magnetic state. A research team from Kiel University has now managed to successfully place a new class of spin-crossover molecules onto a surface and to improve the molecule’s storage capacity. The storage density of conventional hard drives could therefore theoretically be increased by more than one hundred fold. The study has been published in the scientific journal Nano Letters.
Over the past few years, the building blocks of storage media have gotten ever smaller. But further miniaturization of the current technology is hindered by...
