What limits the behaviour of a carbon nanotube? This is a question that many scientists are trying to answer. Physicists at University of Gothenburg, Sweden, have now shown that electromechanical principles are valid also at the nanometre scale. In this way, the unique properties of carbon nanotubes can be combined with classical physics "“ and this may prove useful in the quantum computers of the future. "We have been studying carbon nanotubes theoretically, in order to see how they...

Researchers at Eindhoven University of Technology (TU/e, Netherlands) have developed a replacement for indium tin oxide (ITO), an important material used in displays for all kinds of everyday products such as TVs, telephones and laptops, as well as in solar cells. Unfortunately indium is a rare metal, and the available supplies are expected to be virtually exhausted within as little as ten years. The replacement material is a transparent, conducting film produced in water, and based on...

In recent years, many airplane manufacturers have started building their planes from advanced composite materials, which consist of high-strength fibers, such as carbon or glass, embedded in a plastic or metal matrix. Such materials are stronger and more lightweight than aluminum, but they are also more difficult to inspect for damage, because their surfaces usually don't reveal underlying problems. "With aluminum, if you hit it, there's a dent there. With a composite, oftentimes if you hit...

Rice University lab uses ruthenium complexes to dissolve nanotubes, add functionality A lab at Rice University has stepped forward with an efficient method to disperse nanotubes in a way that preserves their unique properties -- and adds more. The new technique allows inorganic metal complexes with different functionalities to remain in close contact with single-walled carbon nanotubes while keeping them separated in a solution. That separation is critical to manufacturers who want to spin...

Carbon nanotubes have many attractive properties, and their structure and areas of application can be compared with those of graphene, the material for whose discovery the most recent Nobel Prize was awarded. In order to be able to exploit these properties, however, it is necessary to have full control of the manufacturing process. Scientists at the University of Gothenburg are closing in on the answer. "Our results show that the metal particles that form the basis of the manufacture of...

Researchers at Brown University and in Korea have described the dynamics behind cutting single-walled carbon nanotubes, cylindrical structures just 1/50,000th the width of a human hair. The tubes are compressed by potent sonic booms, causing them to buckle at certain points at helical, 90-degree angles. The finding could lead to better-quality nanotubes for potential use in automotive, electronics, optics and other fields. Results appear in the Proceedings of the Royal Society A.A pipefitter...

Given their outstanding mechanical and electrical properties, carbon nanotubes are attractive building blocks for next-generation nanoelectromechanical devices, including high-performance sensors, logic devices, and memory elements.  However, manufacturing challenges associated with creating well-ordered arrays of individual carbon nanotubes and the nanotube-devices' prevalent failure modes have prevented any large-scale commercial use. Now, researchers at Northwestern University, the...
