Synthesis of structurally pure carbon nanotubes using molecular seeds

08-08-2014

For the first time, researchers at Empa and the Max Planck Institute for Solid State Research have succeeded in "growing" single-wall carbon nanotubes (CNT) with a single predefined structure - and hence with identical electronic properties. And here is how they pulled it off: the CNTs "assembled ...

Nanotubes laid out in stripes

10-06-2014

A number of technical innovations of recent times involve the use of thin layers of carbon nanotubes. In 2013, for instance, scientists from Stanford University (USA) presented the prototype of a computer whose electronic components are based not on silicon but on carbon nanotubes. And nanotubes ...

Research combines graphene and painkiller receptor

14-05-2014

Almost every biological process involves sensing the presence of a certain chemical. Finely tuned over millions of years of evolution, the body’s different receptors are shaped to accept certain target chemicals. When they bind, the receptors tell their host cells to produce nerve impulses, ...

Graphene for real-world devices

New research in phonon scattering sheds more light on graphene as a replacement for silicon

08-05-2014

Graphene, a one-atom-thick form of the carbon material graphite, has been hailed as a wonder material — strong, light, nearly transparent, and an excellent conductor of electricity and heat. But a number of practical challenges must be overcome before it can emerge as a replacement for silicon ...

Nanotube coating helps shrink mass spectrometers

27-03-2014

Nanotechnology is advancing tools likened to Star Trek's "tricorder" that perform on-the-spot chemical analysis for a range of applications including medical testing, explosives detection and food safety. Researchers found that when paper used to collect a sample was coated with carbon nanotubes, ...

Process to 'dope' carbon filaments

Engineers invent a process to 'dope' carbon filaments with an additive to improve their electronic performance, paving the way for digital devices that bend.

19-03-2014

Engineers would love to create flexible electronic devices, such as e-readers that could be folded to fit into a pocket. One approach they are trying involves designing circuits based on electronic fibers, known as carbon nanotubes (CNTs), instead of rigid silicon chips. But reliability is ...
